Agallia bigelovia Bale. 



Psyche, V'll., 240, Sup., p. 26, i8q6. 



Form similar to sangioinolenta, but broader, more robust, color pale- 

 grayish, obscurely marked with fuscous, spots on vertex and scutellum 

 large, black. Length, 3 mm., width, 1.50 mm.; c? slightly smaller. 



Vertex very broad and full, nearly half as long as pronotum, eyes 

 much wider than pronotum. Face broad, genae with a very slight con- 

 striction, then almost straight-margined to the clypeus. Front broad 

 above and nearly parallel-margined, rounding below, but much broader 

 than clypeus. Pronotum short and broad, lateral margin obsolete, 

 humeral margin rounding, very oblique, elytra broad, not as strongly 

 convex as in sanguinolenta, somewhat exceeding the abdomen. Vena- 

 tion slightly irregular. 



Color: Pale yellowish-gray , vertex light, with two large round 

 spots as in sanguinolenta, black, sometimes a broad, indistinct median 

 line and a triangular spot next each eye connected with the ocelli by 

 a slender line, reddish-brown, face pale, sutures and frontal arcs indis- 

 tinctly reddish-brown. Pronotum gray, sometimes with indistinct 

 longitudinal brown bands, scutellum with two black triangles just 

 within the basal angles and extending forward under pronotum. 

 Elytra pale-gray with fuscous nerves on the corium beyond the branch- 

 ing of the first sector, a few narrow fuscous lines on clavus. 



Genitalia: 9, ultimate ventral segment broad and short, posterior 

 margin consisting of two lateral rounding lobes and two intermediate 

 acuminate ones slightly narrower and shorter, their median incision 

 reaching nearly to the base, pygofers broad and short, cf' valve nar- 

 row, not more than half wider than long, margins parallel, disc in- 

 flated, convex, plates three times the length ol the valve, sub-cylindri- 

 cal at base, laterally compressed at apex, giving them a long, triangu- 

 lar appearance, pygofers much inflated, enfolding the base of the plates, 

 rapidly narrowing to a point before the apex of the plates. 



Lower California, Mexico; Winslow, and Albuquerque, New Mexico. 



The original description was from a single female with much shorter 

 elytra than the average. Readily distinguished by its stouter appear- 

 ance and distinct genitalia. 



Agallia cinerea, n. .sp. 



Form of a small sanguinolenta, the vertex slightly longer and stronger, 

 elytra even shorter and broader, about equaling the abdomen, pale-
