tubercle and the other features agreeing, there is no room for question. 

 Strecker described htia as an Hydraccia in 1899 (Lep. Rhop. & 

 Het., Suppl. 2, p. 6), so the earlier Grote name must be retained. Its 

 early history is unknown, and but one other example identified as 

 such, is all that the writer recalls having knowledge of. So the quest 

 for two rarities merges into one, a thing to be thankful for when we 

 arc seriously pursuing larval histories. 



ANOTHER SPECIES OF PERO HERR. SCHAEF. 



By Richard F. Pearsall,

In Proceedings of U. S. National Museum (Vol. 38, pp. 359-376) 

 Mr. J. A. Grossbeck has recently published a very thorough and excel- 

 lent paper, separating the various species formerly massed as one 

 under the old genus Azclina Hub., and placing them under the genus 

 Pero Herr Sch., where they rightly belong. The inclusion of occi- 

 dcntalis Hulst (Mannarca) and of Colorado Gross., both having den- 

 tate antennae in the males, does not accord with my present opinion, 

 but it does not detract in any way from the value of the service he 

 has performed. In concluding a brief summary of results, he remarks 

 (page 360) "that several examples have been treated as geographical 

 races, but may yet be found to be distinct." One of these I have 

 received since my material was submitted to him in a series of nearly 

 one hundred, including both sexes. Mr. Grossbeck, who has seen 

 them, advises me that he had several poor specimens before him, but 

 the similarity in genitalia to niodcstus Gross and the paucity of his 

 material deterred him from separating them from it at that time. It 

 is to be noted that the home of this new species is in northern Utah, 

 while modest Its occurs most plentifully in southern and central Ari- 

 zona, though I have one straggler from Durango, Col. All of my 

 specimens were taken from May 7 to June 24, excepting a single 

 pauperized male on August 3, while my large series of niodcstus were 

 captured in September and October. Apart from their apparent un- 

 likeness when the groups are contrasted, they can not be seasonal
