THE CANADIAN ENTOMOLOGIST. 79 



Vertex rather narrow, slightly longer than in fuscipennis, parallel- 

 margined and slightly depressed. Anterior margin merged with front, 

 except for a slight production at apex. Front broad and short as in 

 fuscipennis. Pronotum slightly wrinkled in the female, distinctly so in the 

 male. Elytra broad and slightly flaring. 



Colour : Vertex, pronotum and scutellum fulvous, irrorate with 

 tawny, the posterior disc of pronotum and a cloud on scutellum darker. 

 Scutellum with the tip and a pair of lateral spots ivory-white, the lateral 

 spots pointed behind and exceeding the line of the margin. Elytra finely 

 reticulate and slightly irrorate with tawny. A few irregular darker spots 

 on the margin and paler ones on disc. Face finely irrorate with pale 

 tawny, without markings. 



Genitalia : Female segment broad and rather short, posterior margin 

 divided into four evenly rounding lobes equal in length, the median pair 

 slightly broader than the lateral ones, and black margined, median cleft 

 slightly deeper than the lateral ones. Male : valve long, triangular, plates 

 strongly gibbous at base, margins slightly narrowing to the broad, round- 

 ingly truncate tips ; together forming a broad blunt-tipped spoon, scarcely 

 as long as its basal width, and only equalling the tubularly inflated 

 pygofers. 



Described from a single pair taken at Washington, D. C. This 

 species, pusillus, and the following one connect the Uhleri group with the 

 more typical Phlepsids. 



Phlepsius utahnus, n. sp. — Resembling pulchripennis, but smaller, 

 lighter coloured, and with a longer, narrower vertex. Length, $ 5 mm.; 



c? 4-5 mm - 



Vertex obtusely triangular, as long as the basal width, and almost as 



long as pronotum, one-third longer on middle than against eye, disc flat, 

 margin bluntly rounding to the front. Front long, narrow and parallel-mar- 

 gined above, narrowing below to the slender parallel-margined clypeus.

Colour : Vertex yellow, ocelli and four points on anterior margin 

 tawny or brown ; disc with a large black spot, concave in front except for 

 a triangular incision on the median suture, pointed behind where it 

 reaches the base, the surface finely irrorate with yeliow. Pronotum 

 irregularly irrorate with brownish fuscous. Scutellum yellow, a pair of 

 quadrate reticular areas inside the basal angles and a pair of round dots 

 against apex, black. Elytra milky, the nervures pale tawny, surface
