56 THE CANADIAN ENTOMOLOGIST. 



Colour : black above, a raised transverse band extending from the 

 costa across the bases of the anteapical cells and running out a little on 

 each nervure, milky white ; the tip of the fourth apical nervure is also 

 white. Below black, a broad crescentiform band across the face, the 

 tibiae and tips of all the femora, yellowish white. 



Genitalia : female segment nearly twice as long as the penultimate, 

 posterior margin rounding, with a slight median emargination. Male 

 valve roundingly triangular, about as long as the ultimate segment ; 

 plates broad, roundingly triangular with the apices acute, nearly three 

 times the length of the valve. 



Described from eight specimens received from the National Museum; 

 from Kern Co., Calif. Coquillett collector. 



Uhleriella signata, n. sp. Plate 2, fig. 4. — Closely resembling 

 Coquilletti, larger and with longer elytra, pattern of marking similar, but 

 without the two white bands on elytra. Length, 5-5.5 mm.; width, 

 1.75 mm. 



Vertex slightly sloping, flat or slightly transversely depressed, not 

 quite twice wider than long, a little over half as long against eye as on 

 middle ; face as in Coquilletti, front narrow, wedge-shaped. Pronotum 

 more strongly convex in front than in Coquilletti, emarginate posteriorly 

 with the outer angles rounded. Elytra long and rather narrow, 

 subhyaline towards the margins, the apex roundingly truncate. Venation 

 resembling Coquilletti in general pattern, but with the outer anteapical 

 cell angled out nearly to the costa and lacking the white bands on the 

 cross nervures, two apical nervures arise from the exposed outer face of 

 the central anteapical cell and run nearly parallel to the costa, forming a 

 long narrow cell ; the second cross nervure wanting. 



Colour: vertex pale yellow, a transverse band just before the middle, 

 parallel with the posterior margin, testaceous brown. Pronotum with 

 four transverse bands parallel with the anterior margin, the anterior one 

 testaceous brown, the next pale creamy or slightly greenish yellow, the 

 third, which does not reach the lateral margins, light testaceous, posterior 

 margin greenish white. Scutellum pale yellow, with large triangular 

 black spots in the basal angles and a pair of interrupted stripes across 

 the disc. Elytra brown, darkest on the clavus, shading out to subhyaline 

 along the margin, the sutural margin and clavai sutures narrowly light, 

 nervures, except the apical ones, broadly so ; apical margin narrowly 

 milk white, bordered inside by a wider smoky band, the bases of the
