Family SATURNIID.E. 



HEMILEUCA MAIA Drury. 



Larva. — Head and feet dark mahooany red in the latst stage, black 

 before that; width 4.5 mm. Body l)laek, thickly covered with second- 

 ary yellow dots centered by black hair tubercles; subdorsal, lateral, and 

 waved substigmatal lines yellow, broken; incisures reddish. Spines 

 all long, some sette white; spiracles black, the elevated spots behind 

 them on joints 5 and 11 reddish. 



This larva is well known in the Atlantic coast region from Massa- 

 chusetts to Florida and has been often desci'ibed. The .voung larvte 

 were found gregariousl}^ on the oak on May 20, in a gulch leading up 

 from the Platte Canyon. They were matured about the 1st of July. 

 No moths were bred, but I can not doubt the identification, as the larva 

 is very familiar to me. 



HEMILEUCA NEVADENSIS Stretch. 



Za/'ri/. — Head, plates, and feet very bright mahQg"aiiy red; width 

 ■4.5 mm. Body with the yellow spots confluent all ovei" the dorsal 

 and lateral spaces, making the ground color yellow except narrowl}^ 

 subdorsally and v(mtrally. Spines of the upper row all bright brown, 

 the long ones with black shafts. 



This larva is well known in the Pacific coast region and through the 

 arid West, and has been described in all its stages. Several were 

 found on willow near Denver by a water course in the prairie, and 

 were matured about the 1st of July, A moth emerged in Septeni1)cr. 



The occurrence of these two species within a few miles of each other, 

 but in different fauna! regions, is interesting, both as illustrating that 

 the}" are different species though so similar, and how the Atlantic 

 coast fauna is interpolated in the middle of the Western one along the 

 foothills of the Rocky Mountains.
