APHROPHORA IRRORATA H. Sp. 



Dark rusty-brown, flecked with lighter, very closely 

 resemhling per iimtata; longer and narrower thSiWparaUela, with 

 a much shorter vertex and a less swollen front; length 

 ll-12mm., width 3.5-4mm. 



Vertex short, transversely depressed, only slightly longer on middle 

 than at eye, anterior margin thin, tylus broad and short, nearly twice 

 wider than long, median carina obscure, front moderately inflated, outline 

 a regular curve from clypeus to vertex, angle with vertex acute, inflation 

 of front less than the long diameter of the eye: pronotum transversely 

 depressed before the middle, posterior disc elevated, carina weak except 

 across the depressions, lateral margins short, their length less than the 

 distance between the ocelli; elytra, long and narrow, much exceeding the 

 abdomen, but little windened at center of costa: costal margins scarcely 

 reflexed: costal area narrow, no more than one-half wider at the angle of 

 the first sector than at the discoid cells. ■ 



Color: Vertex, dark rusty-brown, median carina and a spot either side the 

 tylus, light; anterior half of the i^ronotum light, with few dark punctures 

 except along the carina, posterior half densely punctured darker; elytra 

 tawny, interrupted by numerous small circles of white, often inclosing a 

 single dark puncture, these somewhat irregularly arranged, but usually 

 showing three light areas, separated by two darker ones along the costa; 

 an oblique light band from the center of scutellum to the center of the 

 corium: a light spot before the apex of the clavus and another behind. 



Genitalia: Female pygofers short and convex, exceeded by the short 

 ovipositor by a distance of less than one-half their width: ultimate ventral 

 segment of male abdomen longer than wide, narrowing behind, convex, 

 shining: plates broad, parallel margined, inner posterior angles excavated, 

 leaving a rounded notch nearly half their depth, outer posterior angles 

 produced, acutely pointed. 



Described from several examples received from Professor 

 Bruner, taken in Sioux county, Nebraska (War-Bonnet 

 Canon), and others taken in Rist Canon (Ft. Collins), Colo. 



This species resembles parallela quite closely in color and 

 marking, and was probably the one referred to by Say as 

 occurring in Missouri and Arkansas. It is quite distinct 

 structurally and may be readily separated by the short vertex, 

 longer elytra and the striking differences in front and 

 genitalia.
