punctures that are separated by about 1.2 their diameter; male sub- 

 genital plate ligulate, a little broader apically than in C. haioda and 

 C. jemoralis, its edges upcurved (in dried specimens there are a pair 

 of longitudinal folds that weakly converge apically and may unite as 

 a single median carina before the apex of the subgenital plate) ; female 

 subgenital plate triangular in side view, shorter than in C. pacifica 

 and a little longer than in C. hatoda. 



Black. Longer hairs of head and thorax light brown; apical 0.4 of 

 mandible ferruginous; orbits (broadly mterrupted above and usually 

 also behind), variable areas on the clypeus ranging from an apico- 

 lateral spot to the entire clj^peus, tubercle between the antennae, 

 apical triangular area on underside of scape, small spot on underside 

 of pedicel, hind margin of pronotum, an anterior spot on pronotum, 

 usually the lower corner of pronotum, more or less of the front of front 

 coxa, usually a small spot on apex of front femur behind and a similar 

 spot on apex of middle femur in front, usually small dorsal subbasal 

 and subapical spots on fore and middle tibiae, an apical external

stripe on middle and hind coxae, rarely a small spot on the scutellum, 

 the postscutellum, a wealdy curved lateral apical stripe (broadly 

 separated medially from the stripe on the other side of the tergite) on 

 each of tergites 1 to 4, often an obsolescent narrow apical sublateral 

 spot on the fifth tergite, and a large dorsal spot on the last tergite, 

 creamy white; legs beyond coxae fulvous, the trochanters strongly 

 infuscate and the tarsi wealdy inf uscate ; flagellum tinged with fulvous 

 beneath, especially in the female; maxillary palpi and tegula fulvous 

 with often some infuscation ; wmgs hyaline, a little infuscate apically. 

 In males the front and middle femora may be infuscate and the clypeus
