304 THE CANADIAN ENTOMOLOGIST. 



rounding median notch ; whole segment often elevated so as to give it the 

 appearance of being angularly emarginate from the lateral angles. Male 

 valve nearly twice as long as the ultimate segment, posterior margin 

 rounding, disc convex or slightly angularly elevated. 



Colour : deep green, the inner two-thirds of clavus from the pronotum 

 back to the middle, where it is abruptly truncate, the membrane and 

 apical cells reddish brown, elytral hairs black. 



Described from twenty-four specimens from Holly, Trinidad, Pueblo, 

 Palmer Lake and Fort Collins, Colo. 



Pediopsis trivia/is, n. sp. 



Resembling viridis, but larger, as large as erythrocephala, but with 

 longer, narrower elytra than in either species. Light green, the male but 

 little darker. Length : $ , 6 mm.; g , 5 mm. Width. 1.5 mm. 



Vertex very nearly right angled, slightly more acute than in 

 erythrocephala, much more than in viridis ; pronotum rather narrow, the 

 rugne fine and distinct ; elytra long and narrow, with long apical celK 



Colour: female entirely light green, no mark on propleura; male 

 light green, the tips of the elytra often slightly embrowned, the tip of the 

 rostrum an oval spot on the propleura, the apices of the anterior tibia? 

 and the apical segments of all the tarsi black. 



Described from twenty-four specimens from Fort Collins, Lamar and 

 Rocky Ford, Colo. In the key this species would follow erythrocephala, 

 to which it is allied in size and shape of vertex. The absence of colour 

 markings in either sex and the unmarked propleura of the female will at 

 once distinguish it, however. The larger size and more sharply-angled 

 vertex will separate it from all the other green forms. 



Idiocerus dolosus, n. sp. 



Form and general appearance of crataegi, slightly broader and 

 darker. Face and pronotum irregularly immacuhte with brown. Length, 

 5—5.5 nun : width, i.S mm. 



Head as broad as in crataegi, much broader than in the other deep- 

 headed species. Vertex not as much curved as in crataegi, longest 

 against the eye?. Face very deep and straight, front full and rounding as 

 in Provancheri ; clypeus short, constricted in the middle and much 

 widened just at the apex ; elytra similar to those of crataegi, inclined to be 

 more flaring, giving the insect a more robust appearance ; venation 

 somewhat obscure, three anteapical cells, the outer one short. Female 

 segment shorter than in crataegi, the posterior margin broadly rounding,
