HALESIDOTA MACULATA Harris, variety ALNI Henry Edwards. 



This species occurs in three forms in the United States. Those 

 inhabiting the northern Atlantic region and the northern Pacitic 

 region, respectivel.y, are indistinguishable in the moth state, though 

 different as larvaj. I have several times received II. maculata from 

 Colorado, but never knew to which race to refer the specimens. Mr. 

 Caudell took a larva near Salida and Professor Gillette has in his 

 collection some cast skins. Both show the red dorsal hairs of ahti, 

 proving the Coloradan form the same as the northern Pacitic coast one.
