surface of the coxae; they are longest in C. macro, and shortest in C. 

 divergens, in the latter of which they are of a size about normal for 

 the family. These lobes are actually not sufficiently different in 

 appearance to be useful in species diagnosis, but they do afford a 

 secondary measure of specialization in the genus. Apparently their 

 size is correlated with divergence in gonopod characters. 



Coloration. — The distribution of metatergal pigmentation is not 

 yet well known enough to be discussed in any detail. The character- 

 istic coloration for most of the species is that of a very dark brown 

 dorsum with deep reddish paranotal spots and red legs. The holotype 

 of C. macra, however, was recorded as having yellow spots. Whether 

 this is a normal phenotypic variation is uncertain. In C. bipraesidens 

 the paranotal red spots are linked by broad red crossbands on each 

 metatergite. C. divergens and its nominal subspecies show an unusual 

 pigmentation of intense bluish-purple or violet paranotal spots and 

 crossbands, a coloration so far known only in two other species of 

 xystodesmids.

Diagnosis. — A genus of large robust xystodesmids with the follow- 

 ing characteristics : 



Body composed of head and 20 segments in both sexes; relatively 

 large and compact in form, W/L ratio varying from 23 to 26 percent. 

 Head of normal appearance, smooth, polished, genae not or but 

 moderately impressed, interantennal isthmus rather broad (up to 

 one-fourth antennal length) ; facial setae reduced, epicranial, inter- 

 antennal, and frontal setae absent. Epicranial suture distinct, not 

 ventrally bifid. Antennae extending caudad to posterior edge of 

 third metatergite; distally with four sensory cones, no other sensory 

 structures. 



Terga of body segments generally smooth middorsally, becoming 

 coriaceous laterally toward and on paranota; latter broad, depressed, 

 continuing slope of dorsum, peritremata broad, flattened, and elevated 

 above adjoining discal surface; ozopores large and distinct, in normal 

 sequence, opening dorsolaterally. Prozonites and metazonites of 

 about same diameter, separated by fine, slightly elevated suture line 

 at front side of stricture, latter shallow middorsally, becoming most 

 sharply defined laterally at level of stigmata. 



Posterior segments of typical appearance for family; hypoproct 

 broadly rounded to transversely oval, with (usually) or without distinct 

 median projection.
