cinereous incrustation, and the elytral interstices each with a scattered series of large, 

 oval or rounded, whitish spots, those along the suture being smaller and more crowded. 

 The rostrum is abruptly bent inwards from the widened basal portion. The femora 

 are fringed with long hairs beneath in both sexes. The prosternum has two small 

 flattened prominences, separated by a short sulcus, at the base.

Abundant throughout the warmer parte of Central America, and easily distin- 

 guishable, when in fresh condition, by the conspicuous whitish lines on each side of 

 the prothorax and between the black markings on the disc of the elytra (the large, 

 oval, oblique patch near the middle of the suture, and the oblong patches at the base, 

 being thus sharply denned). The black marks near the middle of the suture are often 

 united into a common, large, heart-shaped patch, which usually extends up the suture 



to the base and is sometimes connected laterally with the humeral spot. The prothorax 

 is nigro-trivittate on the disc, the outer vittse (sometimes interrupted or reduced to a 

 short streak) being placed at some distance from the margin. The variety rubellus 



(fig. 5) (found in numbers at Zapote, Guatemala) is ferruginous, with the black

markings reduced in size and the whitish lines only just traceable. B. quinquemacu- 

 lotus, Chevr. (fig. 6) (the type of which I have seen), seems to be a very dirty, pallid, 

 female example of JR. cinctus. Some of Biolley s specimens were found on a species of 

 Vernonia (order Composite) in Costa Rica.

 apical portion stout and compressed, very sparsely punctate to near the tip, the punctures becoming 

 coarse towards the base ; first ventral segment obsoletely depressed down the middle.
