lower two thirds of eye; cheeks very coarsely sculptured, irregularly 

 punctate-reticulate; malar carina weak, curving backward before 

 meeting the eye; subgenal and postgenal carinae strong. Antennae 

 very stout, flagellar joints after the second fully twice as wide as long, 

 those near apex nearly three times. Eyes bare; head and body hairs 

 glistening white. Thorax above umbilicately punctate; lateral 

 carinae of pro thorax well developed; each as long as the median 

 space between them. Scutellum at apex with a deeply bilobed pro- 

 jection. Abdomen smooth, with very fine punctures on the sides 

 of the third and following segments. Hind femur about twice as 

 long as wide, with a small projection inwardly near base, their inner 

 surface smooth, outer surface very sparsely and finely punctate; 

 about 13 femoral teeth, basal ones, except first, and apical ones smaller 

 than the others. AVings nearly hyaline; postmarginal vein half as 

 long as the marginal and twice as long as the stigmal. 



C. terribilis may be known by the configuration of the facial carinae 

 and banner-like color-pattern of the hind femora.

9 . Length 3.2-4 mm. Black; the tegulae pale yellow; front 

 and middle knees, tips of tibiae and tarsi honey-yellow; extreme 

 apices of hind femora, ring including basal fourth of tibiae, apex 

 externally of tibiae, and tarsi, yellow. Pubescence of body whitish. 

 Head rugose-punctate above; ocelli in a low triangle, the lateral 

 ones less than their diameter from the eye-margin, eyes bare or nearly 

 so; cheeks smooth; malar carina dividing just below eye, one branch 

 extending along the inner orbit as a light carina, the other branch 

 extending to the hind margin of the head so as to enclose the cheek 

 in the form of a rhomboid between carinae. Antennae rather slender, 

 the middle joints of the flagellum less than twice as broad as long. 

 Thorax closely umbilicately punctate; lateral carinae of pronotum 

 weakly developed, each about as long as the space between them. 

 Scutellum simple, sharply rounded at apex. Abdomen shining, sides 

 of third to sixth segments faintly shagreened, hairy: apical two seg- 

 ments coarsely shagreened. Posterior femora very broad, distinctly 

 more than half as wide as long; internally near base without distinct 

 tubercle, although there is a slight trace of one; underside with about
