The tliive species last named, wliieli are from the Pacitic <3oast or 

 the Nortliwest, may be further distiiiguislied in that H. devorata has 

 the palpi distinctly shorter than in the two others, resembling II. 

 humuli ill that respect and in the less marked angulation of the outer 

 margin, which in the male is very slight. H. californU-a and H. ntodc.sta 

 have excessively long palpi, proportionately longest in the latter, while 

 the outer margin is more angulated; also most obviously in H. modesta 

 and particularly in the male. 



We can follow the modifications of the transverse posterior line in 

 much the same way. H. liumiiU has it irregularly sinuate and bent, 

 with an outcurve in the submedian interspace and an inward tooth on 

 the internal vein. H. decorata has the line nearly rigid, only a little 

 sinuated, has the outcurve in the interspace less marked, but the 

 inward angle distinct. H. californica has the line more rigid, but with 

 small dcnticulatious on the veins; the outcurve in the interspace has 

 disappeared, while the inward angle is acute and well marked. Finally, 

 H. modesta has the line absolutely rigid and even to the inward angula- 

 tion on vein 1.
