Diagnosis. — This is the only species known in this well-marked 

 genus. 



Description. — Male : 



Head: Length nearly three-fourths width, 0.64(0.58-0.70): 0.89 

 (0.83-0.98); interocular width, 0.63(0.60-0.68); juga as long as 

 clypeus, narrowing it apically; juga and vertex with numerous, irregu- 

 larly placed punctures; ocelli small, separated from eye by a space 

 almost three times transverse ocellar diameter; jugum ventrally and 

 maxillary plate impunctate. Antennal segments: I, 0.20(0.17-0.23); 

 II, 0.13(0.12-0.14); III, 0.27(0.24-0.29); IV, 0.27(0.23-0.31); V, 0.33 

 (0.32-0.34). Bucculae low, height about half of labial II. Labial 

 segments: I, 0.31(0.30-0.33); II, 0.48(0.46-0.50); III, 0.39(0.36-0.43); 



IV, 0.26(0.26-0.29). 



Pronotum: Length a little more or less than half of width, 1.0 

 (0.90-1.17) :2.02(1.82-2.28); anterior lobe polished, moderately punc- 

 tured except for U-shaped discal area, punctures slightly coarser 

 towards margins; posterior lobe with numerous close-set punctures 

 similar to those of transverse impression. 



Scutellum: Distinctly wider than long, 1.34(1.17-1.49) :1. 02(0.90- 

 1.10); surface, except basal angles, moderately closely punctured al- 

 most to apex, latter with a low, median carina. 



Propleurae, mesopleurae, and metapleurae: As described for genus. 



Legs, sternites, and terminalia: As described for genus, gonostylus 

 as illustrated (fig. 196). 



Length of body: 3.74(3.35-4.12). 



Female. — Very similar to male, but punctures of posterior pronotal 

 lobe a Httle coarser and more distinct; and measurements more 

 variable. 



Head: Length-width ratio, 0.64(0.55-0.68) : 0.92 (0.80-1. 00); inter- 

 ocular width, 0.65(0.56-0.72). Antennal segments: I, 0.21(0.17- 

 0.26); II, 0.13(0.13-0.16); III, 0.28(0.25-0.33); IV, 0.29(0.26-0.33); 



V, 0.33(0.27-0.37). Labial segments: I, 0.34(0.32-0.38); II, 0.52 

 (0.44-0.60); III, 0.40(0.34-0.51); IV, 0.28(0.27-0.31). 



Pronotum: Length-width ratio, 1.08(0.84-1. 19):2. 11(1.75-2.28). 

 Scutellum: Width-length ratio, 1.36(1.07-1.56):1. 10(0.91-1. 19). 

 Length of body: 4.02(3.42-4.35). 



Type data.— Uhler (1876, p. 278) reported the type "From the 

 vicinity of San Francisco." The other locality given in the original
