curved black bars outwardly, the others entirely pale, tho anal pair 

 with gray reticulations. Tubercles small, i showing blackish; setae 

 fine, obscure. 



HELIOPHILA COMMOIDES Guenee. 

 Two specimens, July 2. 



HELIOPHILA HETERODOXA Smith. 



Five specimens, May 29, June i, 4, 11. The ])asal streak on fore 

 wings may be faint {heterodo.ni Smith) or distinct {luegadia Smith). 

 There is obviously no specific difference between these forms. The 

 species is close to insueta Guenee and apparently only a geogi-aphical 

 expression of it; yet, being lighter and slighter than its eastern ally, 

 it violates the usual rule for western races, and I would not, therefore, 

 unite these forms specificall3\ 



Eggs were obtained from captive females in good season; the larvaa 

 were fed on grass.
