being sometimes very small (P. trumata^ fig. 7), or the two are nearly equal 

 (P. diversilineata, fig. 7a); the subcostal venules are long, snbparallel with 

 the costa, and are arranged much as in Glaucopteryx, the second subcostal 

 arising midway between the first and tiiird ; when present, the anterior discal 

 venule is much curved outward, and the posterior venule is bent at a high 

 angle. Hind legs with the tarsi as long as the tibiae. Abdomen very long 

 and slender, ending in a conical tuft, with dorsal' ami lateral projections. 

 Coloration : either gray, with numerous zigzag bands, and an apical, light, 

 zigzag streak, shaded with dark beneath, or some shade of black or yellow 

 oclireous, with fine dark lines enclosing squares and triangles. On the hind 

 wiiigs are usually two rudimentary lines. 



The species of this large genus have a style of coloration and facies 

 that enable them to be distinguished from Glaucojjteryx on the one hand 

 and Ochyria on the other. From the former genus, it ditfers in the more 

 decidedly falcate fore wings, the narrower head, stouter, longer palpi, and 

 smaller, shorter hind wings. From Ochyria, it diifers in the antennae always 

 being ciliated, the cilia being short, in the much longer palpi, and in the 

 much more falcate fore wings, while the species are usually much larger. 

 The natural divisions of the species of the United States are indicated in 

 the synopsis of the species. 



Larva. — "Elongated, smooth, slender, stifl" (raide), pedunculiform, not 

 attenuated anteriorly; with the liead larger than the neck [prothoracic 

 segment], flattened in front, and often bifid at the summit; living on trees 

 or shrubs." 



Pupa. — "Of various colors, spotted or punctuated.'' — (Guen^e.) 



The characters of tiie larva of our P. diversilineata agree with those 

 quoted above from M. Guentie's work.
