[[female symbol]] Sphingicampa distigma came out today which had the whole spot next the Costa invisible & the other very small & scarcely noticeable. [[line]] I was mistaken in thinking that in Cordulina the ant. [[image - triangle]] is always full as robust as post. [[image of triangle]], & always slenderer in Lebillulina. In Macromia flavipennis [[underline]] ant [[/underline]] [[image - triangle]] is slender, & in Celithemis eponina [[image - triangle]]'s are nearly alike. [[line]] From Baird's N.A.

When the number of speracles is normal, that is one pair on the thorax & one on [[underline]] all [[/underline]] (?last [[insertion]] ¶ p. 64 [[/insertion]]) abdominal segments, then the larva is called [[underline]] peripneustic![[/underline]] Finally, when there is only one pair [[end page]] [[start page]] (64 (as in Ctenophora) at the end of the body, the larva is [[underline]] metapneustic.
