THE CANADIAN ENTOMOLOGIST. 309 



segment long, broadly rounding posteriorly ; pygofers moderately long, 

 much inflated, the ovipositor exceeding them by about twice its width. 

 Male antennae with very slight black-marked enlargements some distance 

 from the apex. 



Colour : face pale yellow, a pair of round black spots on vertex, and 

 sometimes a cloud of olive brown between them ; pronotum olive and 

 cinereous, with about six small black spots on the middle half ; scutellum 

 pale yellow, with its basal angles and a pair of spots on disc brown or 

 black ; elytra pale subhyaline olive brown, the tips of the outer claval 

 nervures and sometimes a spot on the inner sector of corium just beyond 

 apex of clavus milky white ; legs and below pale. 



Described from twenty-four specimens from Vancouver Island, B. C. 

 These, together with the specimens of concinnus and amabilis, were part 

 of a nice lot of Jassids sent me several years ago by Mr. Livingstone. 



Idiocerus verrucosus, n. sp. 



Form and general appearance of brunneus, but much smaller, with a 

 long anteapical cell and simple antennae. Pale cinnamon brown, with 

 heavy dark markings on vertex and front. Length, 4.25 mm.; width, 

 1.5 mm. 



Face broad and very deep, not retreating until nearly the middle of 

 front, sides of genre perfectly straight ; pronotum very short and broad ; 

 elytra with the nervures heavily tuberculate, the outer anteapical cell long 

 and narrow. Female segment long, slightly rounding posteriorly; pygofers 

 moderately long and stout, much longer and stouter than in brunneus, 

 exceeded by the ovipositor by about twice its width. Male valve 

 long, but feebly excavated each side the middle. Male antennae with 

 a very fine filament. 



Colour : pale cinnamon brown, tinged with fuscous in the male ; 

 vertex and face down to antennse with a dark brown or fuscous band, the 

 black spots on vertex surrounded by light circles, and the ocelli in the 

 inner ends of transverse light dashes. In light examples this band may be 

 wanting or only present as a pair of black marks against the eyes. 

 Pronotum and scutellum marked as in musteus. 



Described from nine specimens from Dutch Georges and Ward, 

 Colo.
