Female. — Length 12 mm. Black with ferruginous markings; 

 punctation and pubescence average for the genus. Structurally like 

 C. flavofasciata flavofasciata H. S. Smith. 



Head reddish amber except for dark amber to black patches just 

 above the antennal scrobes, the ocellar area, patches on the vertex 

 bordering the eyes and the lower genal area, and the following parts, 

 which are yellowish amber: large frontal eye patches, frons above the 

 clypeal process, lateral lobes of the clypeus, and the basal part of the 

 mandibles; apical part of mandibles and mandibular denticles dark 

 amber; antennae ferruginous becoming dark apicaUy. 



Thorax black except the pronotum, scutellum, metanotum, most 

 of the propodeum exclusive of the enclosure, patch on the pleuron, 

 and the tegulae, all of which are ferruginous; legs reddish amber; 

 wings clouded with amber. 



Abdomen: tergum 1 and 2 reddish amber with a narrow yellowish 

 line on the posterior half of tergum 2 ; terga 3 to 6 black with a trace 

 of dark amber on the anterior part of tergum 3; sternites 1, 2, and 3 

 largely ferruginous. 



Male. — Length 10-12 mm. Black with dark ferruginous mark- 

 ings showing some yellowing; punctation and pubescence average; 

 structurally like the nominate subspecies male. 



Head black except for the face, which is light ferruginous medially, 

 becoming darker on the clypeus ; genae and vertex largely ferruginous ; 

 width of the clypeal extension on the medial lobe about one-half the 

 length of the epistomal suture, with three subequal small denticles 

 on the margin ; mandibles with one prominent acute denticle; antennae 

 normal in form. 



Thorax black except for a broad band on the pronotum, scutellum, 

 metanotum, and large patches on the propodeum, all of which are 

 dark ferruginous; enclosure smooth except for a light medial groove; 

 legs amber; wings clouded. 



Abdomen black except for the first two segments, which are dark 

 ferruginous with a narrow yellowish band on the apical border of the 

 second tergum. 



The males of several closely related species and subspecies in 

 Florida and adjoining areas have been confused by earlier workers.
