angulated in the same way. Veuation : the costal region is very narrow; the 

 costal vein anastomoses with the subcostal vein; there is no subcostal cell; 

 the anterior discal venule is short and regularly curved, the posterior one 

 very oblique. The hind tibiae are but slightly swollen, the tibia? large, long, 

 and thick. * Coloration: either deep ocbreous, with the basal and extradiscal 

 lines more or less obsolete, or white (subsignaria) and immaculate. 



This genus is readily distinguished by the full, hairy, projecting front, 

 the long, porrect palpi, the heavily-pectinated male antenna?, those of the 

 female being also pectinated, by the deeply-scalloped wings, and the hairy 



body. 



Larva. — The body is rather thick; head large and round; a spine in 

 tin 1 middle and near the end of the body; sometimes the body is thickest 

 near the end of the body. Pupaa pale in color, situated between leaves.

Larva. — The caterpillar closely resembles the twigs of the elm-trees, 

 on the leaves of which il lives, the body being brown, while the large head 

 and terminal segment of the body is bright red. A writer in the "Practical 

 Entomologist" (vol. i, p. 57) states that the caterpillars are hatched as soon as
