THE CANADIAN ENTOMOLOGIST. 41 



I quote the original description. Larger series of this species show 

 some variation from the types. With the exception of two specimens 

 from the collection of the 111, State Lab. Nat. Hist. (Ace. 1880-4620), I 

 have seen no specimens taken outside of Colorado. This form may 

 eventually prove to be a variety oi pufictatus. In cotifusus the vertex is 

 evenly rounded, not produced, while in punctatus it is distinctly pro- 

 duced. Cotifusus also lacks the conspicuous maculation of the elytra. 

 In some specimens the markings vary to a bright fulvous.

^ Distinguished by the more or less strongly maculated elytra and 



produced vertex. Otherwise very closely resembling cotifusus. A care- 

 ful comparison between series of the American forms referred to this 

 species, and authentic specimens of the European punctatus, would be 

 very desirable. 



This species is probably widely distributed in the U. S. I have 

 collected it at Ag. Coll., Michigan, and at Fort Collins, Colo., and also 

 have specimens from Ithaca, N. Y. (Cornell Univ. Coll.). There is con- 

 siderable variation in colour, some specimens having strong pink or 

 roseate suffusion, others being quite strongly green. 

 Gnat/iodus occidentalism n. sp. 



Head narrower than pronotum. Face an eighth wider than long. 

 Front about a half longer than wide, and twice the length of the clypeus. 

 Clypeus gradually broadening to the very slightly rounded tip. Genaj 

 broad below lorne. Vertex very slightly produced at the middle. Pro- 

 notum about seven-eighths wider than long, three and two-thirds the 

 length of the vertex, curvature seven-fifteenths of the length. Last 

 ventral segment of female truncate at tip. Ovipositor equalling pygofers, 



*The synonymy of this species is essentially the same as that given by Mr. Van- 

 Duzee in his " List of N. A. Jassoidea." The extended European bibliography I do not 

 attempt to give.
