THE CANADIAN ENTOMOLOGIST. 153 



Vertex short and broad, nearly twice wider than long, the anterior 

 margin roundingly angulate, almost parallel with the emarginate posterior 

 margin, vertex scarcely reaching the anterior margin of eyes, beyond 

 which the gibbous front extends for about half the length of vertex. 

 Face very broad and full, convex, with the median carina indistinct or 

 wanting. Elytra broad and flaring, nervures strong, weakly black- 

 punctured and beset with long white hairs. 



Colour: vertex and front dark testaceous, the carina? light yellow, 

 pronotum light, scutellum light testaceous. Elytra milky subhyaline, 

 nervures brownish at the base, then smoky, the cross nervures and apex 

 margined with fuscous, the nervures clothed with long white hairs. 



Male pygofers long and slender, deeply angularly notched with a 

 small tooth. Styles as in conp/ectus, but longer and leaving a large open 

 space in the curve. 



Described from seventeen specimens from Las Animas, Colo. Easily 

 distinguished by the short head. 



My ml us viridis, n. sp. 



Form of impunctatus nearly, but smaller and narrower. Length : $ 

 5 mm, c£ 4.5 mm.; width 1.5 mm. 



Vertex twice longer than wide, very slightly constricted before the 

 middle, face as in impunctatus, the median carinae of clypeus indistinct. 

 Elytra long and narrow, without a stigma. 



Colour : bright grass green, fading to yellowish-green in old 

 specimens. Elytra subhyaline. 



Male pygofers almost truncate posteriorly, with a triangular median 

 tooth. Styles moderately long, their enlarged oval apices slightly 

 overlapping. 



Described from fourteen examples from Grand Junction and a pair 

 from Ames, Iowa. The green colour will at once separate this from any 

 described species. 



Myndus impiger, n. sp. 



Form and general appearance of impunctatus. Smaller and less 

 plainly marked. Length ? 4.5 mm.; width £.5 mm. 



Vertex rather broad, expanded at the base, where it is more than half 

 as wide as its middle length, face broad, the median carina? of clypeus 

 distinct throughout. Elytra similar in shape to those of impunctatus, 

 broader than in viridis and with a distinct stigma.
