1*^^ THE CANADIAN ENTOMOLOGIST. 



The small size will readily distinguish this species. In general the 

 $ s are darker and more obscurely marked than the ^ s. Fresh speci- 

 mens also appear considerably darker than those that have been in the 

 cabinet some time. 



Family Notodontidœ. 

 Hyperœschra stragula, var. ochreata. var. nov. 



?• — Primaries pale ochreous brown, maculation as in stragula; on 

 costa between basal and t. a. lines a bar of blue-black extending down- 

 wards to first brown dash in cell and somewhat sprinkled with whitish ; 

 just beyond the discal lunule a large blue-black patch, rather irregularly 

 circular, resting on costa, defined outwardly by the t. p. line, basally by 

 vein 3 ; this contains two whitish patches, one between veins 4 and 5, the 

 other smaller between veins 6 and 7, and opposite the discal lunule it is 

 indented with white ; costal area between it and t. a. line whitish, con- 

 taining the reddish-ochre discal mark ; terminal area blue-black ; basal 

 half of inner margin broadly blue-black crossed by the pale cuived t. a. 

 line. Secondaries white ; fringes shaded with blue-black at inner angle. 

 Expanse, 46 mm. 



Habitat : Provo, Ut. (July 21st), i $ . Type, collection Barnes. 



The large circular black mark beyond cell is very characteristic, the 

 ground colour is paler than in stragula and the s. t. line much less waved. 

 May prove to be a distinct species on receipt of more material. 



Fa mi ]y Jhyatiridœ. 

 Habrosyne redangula, var. arizonejisis, var. nov. 



Ground colour of primaries and thorax mouse-gray with none of the 

 brownish shading characteristic of rectangula ; white dash at base of wing 

 reduced in size ; pinkish-white costal and subterminal shading somewhat 

 reduced ; secondaries similar to ground-colour of primaries, not brownish 

 as in the type form. 



Habitat: White Mts., Ariz., i $. Type, collection Barnes. 



Family Geometridœ. 

 Genus Grossbeckia, gen. nov. (type G. semimaculata^ sp. nov.). 



Antennae of ^ shortly bipectinate ; palpi long, drooping, pointed at 

 extremity, smoothly scaled ; fore legs with the femur slightly hollowed 

 out distally to receive the tibia which is ^ the length of the femur and 

 possesses a slight hair pencil beneath, concealing the epiphysis j posterior
