mon at Ogden, Utah. The males are very different in form 

 from the females and it is not at all surprising that they were 

 described as a distinct species. I am almost convinced that this 

 is identical with Telamona Rileyi Godg. the female of which 

 was described as Coquilletti Godg. The Cornell University 

 collection has a broken female from Arizona that answers very 

 closely to Goding's description of his Coquilletti. So far as I 

 can make out it is but a color variation of pulckella Ball. 



Genus Archasia Stal. 



The form of the pronotum in this genus is much the same 

 as that we find in Membracis but here the colors are a uniform 

 green with brown or black points along the dorsal carina in 

 some species. Tlielia conica Walker, listed as an Archasia by 

 Goding, is a Telamona near extrema Ball. Thelia pallida Fair- 

 maire, placed in Archasia by Stal, is still unknown to me. Our 

 other two species may be separated as follows: 



Dorsal edge distinctly brown or fuscous, the contour obviously 

 concave before the apex, 2, Bclfragci Stal. 



Dorsal edge concolorous or faintly dotted with brown, contour 

 scarcely if at all concave before the apex, 



i, gal cat a Fabr. 



1. Archasia galeata Fabricius. 



In the northern states at least this species is less abundant 

 than the next. In the south it is probably the prevailing form, 

 I have taken it in Colorado and Georgia. 



2. Archasia Belfragei Stal. 



This larger and more clearly marked species is the predom- 

 inant form about Buffalo and in fact throughout the northern 

 States. Like the preceding it is generally if not always taken 

 on oaks. Prof. C. W. Johnson reports it as common in eastern 

 Massachusetts two seasons ago. Mr. W. J. Palmer has taken 

 it at Mt. Balsam, N. C.
