VITTATE CHRYSOMELID BEETLES DISONYCHA — BLAKE 57 



fourth joints pale at apex, remainder dark. Prothorax not twice as 

 broad as long, rather convex, sides rounded, a slight depression over 

 scutellum, feebly alutaceous, pale with indefinite pale brownish areas 

 possible indicating spots in a more heavily marked specimen. Scutel- 

 lum pale. Elytra with a narrow dark sutural vitta not extending 

 about scutellum to base or reaching the apex and with a very narrow 

 median vitta not reaching the base, surface alutaceous and feebly 

 shining, finely and rather densely punctate. Body beneath entirely 

 pale, the claws only darker in coloring. Length 7.5 mm., width 3.8 

 mm. 



Type: Male, MCZ 29046, a single specimen with an old label 

 bearing the locality Brazil and the name "Caeporis? nov. sp." 



Remarks: This pale beetle with extremely narrow elytral vittae 

 that do not extend to the base resembles some specimens of the 

 militaris group, but the stouter antennae and very different aedeagus 

 sufficiently differentiate it.
