Pseudohazis, n.gen. 



The body is comparatively slender, avid shortly and sparsely 

 scaled. Head, small ; clypeus, narrow, evenly and rather densely 

 covered with short squamation. Eyes, improminently small or 

 sunken. Antennae, rather long, with broad, dependent pectinations, 

 which are strongly setose. The antennal insertion is brought more 

 forward than in Hemileuca. Thorax, slender and narrow, shortly 

 and sparsely scaled. Legs, short and slight, finely scaled and 

 feebly armed. Wings, ample, rather long, evenly and closely 

 covered with short scales. Nervules, long and straight. Compared 

 with Hemileuca, in which the median nervules are short, arched, 

 and arc thrown off from beyond the middle of the wing, the dif- 

 ference in the course and length of the discal nervules is very 

 palpable. On the primaries the 2d m. nervule is thrown off 

 before the discal cross vein ; the 3d shortly follows, nearer to the 

 base of the wing, and all three median nervules are longer, and go 

 more straight! y to the external margin of the wing. The same is 

 true of the median nervules of the secondaries, where, also, the 

 course of the sub-costal nervules is opposed to that in Hemileuca. 

 In the present genus, the s. c. nervules run straightly to the 

 external margin, whereas in Hemileuca they are bent upwards, and 

 are shorter, the first s. c. being prominently arched to the apex 

 of the secondaries. The hind wings are more rounded and less 

 ovate in Hemileuca. 



The habitual coloration exhibits a resemblance to that of 

 the genus Hazis, Boisd., and has suggested the generic name. 

 The species are yellowish and black, with a common extra 

 mesial band and discal blotches on both wings. 



Our species are Pseudohazis eglanterina {Saturnia cglante- 

 rina, Boisd., Telea eglanterina, H — S. Lep. Exot. 445) from 

 California, and Pseudohazis hera {Saturnia Hera, Harris), 

 from the Rocky Mountains. 



The North American genera, belonging to the tribe Jlemi- 

 leucini, are as follows : Hemileuca, Walk., (maia) ; Pseudo- 

 hazis, G. & R., (eglanterina, hera) ; Coloradia, Blake, (pan-
