314 JOURNAL OF THE WASHINGTON ACADEMY OF SCIENCES VOL. 37, NO. 9 a sharp tooth at each corner; surface very smooth and often impunctate, in some specimens a very fine punctation; reddish brown with a large transverse dark band, in paler specimens this band broken into two large spots. Elytra with small humeri and short intrahumeral sulci, a slight depression below basal callosities; punctation not very coarse and only the two lines next to the suture entire, the other rows of striate punctures becoming indistinct toward the apex; yellowish or reddish brown with piceous markings over the basal callosity and below humerous on the edge of the elytron, in darker specimens a spot on the side and one on the margin halfway down the elytra. Body beneath and legs pale and shining. No teeth on femora; in darker specimens a dark ring about constriction of femora near the apex; claws toothed. Length 2.7-3.4 mm; width 1.4-1.6 mm. Type male and 3 paratypes, M.C.Z. no. 27682; 1 paratype, U.S.N.M. no. 58359. Type locality.——Guanica, Puerto Rico, collected June 25, 1934, by C.M. Matos (Stuart T. Danforth Collection). Remarks.——In its unusually heavy prothorax this species resembles M. cinctipes Blake from the Dominican Republic. It is a considerably smaller species with less distinct punctation. Alethaxius tortuensis, n. sp. Fig. 7 Length 4 mm, broadly oblong, shining, densely punctate, deep bronzy dark green with a bluish luster over the prothorax; legs and antennae and undersurface reddish brown. Thorax with two undulating teeth on the sides; all femora toothed; female without noticeable elytral rugosities, the punctation on the sides somewhat coarser and with a slight tendency toward costation in apical half. Head with fine wrinkles radiating from the vertex and on back of head becoming striate punctation; lower front coarsely and not very densely punctate; deep shining greenish black, the mouth parts brown. Antennae reaching well below the humeri, the five distal joints thickened and with the apical half dark. Prothorax not twice as broad as long, with a prominent tooth at apical angle, two rounded teeth on the margin, and a small tooth at basal angle; basal margin sinuate; surface shining, densely punctate in basal half, the punctures in apical half becoming striate and less dense, with the smooth intervals between them a little raised; except for these costae and somewhat larger lateral punctures, little trace of other rugosities. Body beneath deep reddish brown, lightly pubescent. Legs with all the femora sharply toothed. Length 4 mm; width 2 mm. Type female, U.S.N.M. no. 58360. Type locality.——Bassin Bleu, Isle Tortue, north of Haiti, collected in April 1929 by E.C. and G.M. Leonard. Remarks.——This is the broadest species yet examined from the West Indies, and unlike the females of other species it has little trace of the elytral rugosities usually present along the sides. Other individuals may show more as there is often considerable variation. Alethaxius acuñai, n. sp. Fig. 9 About 3 mm in length, oblong, densely punctate, shining, deep reddish brown with a faint aeneous lustre more marked on the prothorax; hind femora with a prominent tooth; margin of prothorax entire; elytra in female with nodulation below the humeri and along the sides, in both sexes the apical half somewhat costate. Head shining, without depressions, with scattered punctures more densely placed on lower front. Antennae brownish, extending well below the humeri, the five distal joints wider and with darker tips. Prothorax about a third wider than long, with rounded, entire sides, a tooth at basal and apical angles; surface densely and moderate coarsely punctate. Elytra in both sexes densely punctate in basal half, in apical half the punctures becoming striate and less dense with the interspaces becoming a little costate; in the female, the lateral costae more developed and irregular, in some specimens with nodules down the sides below the humeri. Body beneath shining reddish brown, the legs and abdomen a little paler, lightly pubescent; the hind femora with a distinct tooth, the two anterior pairs of femora with vestiges of toothing. Length 2.8-3.6 mm; width 1.4-1.7 mm. Type male and 2 paratypes (female), U.S.N.M. no. 58361; 1 paratype in M.C.Z. Type locality.——Moa, Oriente Province, Cuba, collected November 3-16, 1945, by J. Acuña. Remarks.——This is the second species to be
