222 Mr. H. W. Bates' Supplement to the 



Of peculiar fades owing to its ratlier broad and sliglitly 

 convex elytra, obtusely rounded at the apex ; it is how- 

 ever a true Ileteracltthes, according to Lacordaire's defini- 

 tion and allied to //. sic/iiaticollis fThoms.) The head 

 (with the eyes) is scarcely broader than the thorax, 

 coarsely confluent-punctate behind, with moderately raised 

 antenniferous tubercles. Antennae ( $ ) shorter than the 

 body, fulvous, sparingly setose ; not thickened or carinated, 

 fourth joint much shorter than the third, a little shorter 

 than the fifth. Thorax cyhndrical, with an obtuse tubercle 

 on each side of the smooth, raised median space. Elytra 

 much wider than the thorax, rather convex, and a little 

 rotundate-dilated beyond the middle, apex obtusely 

 rounded ; densely setose ; above punctulated ; the ground 

 colour is chestnut-brown, varied Avith large pale-tawny 

 spots, the first lateral at one-third the length and emitting 

 a streak to the humeral callus, the second beyond the 

 middle forming a rather oblique subdentate fascia, the 

 third rounded at the apex. Body beneath and legs 

 reddish-chestnut. Legs rather short ; femora clavate ; 

 tibia3 without grooves. Prosternum extremely narrow 

 between the coxjb. 



Section B. Eyes finely facetted.

Allied to C vchitiman and holochlorum, but differing 

 from all tropical American Callichromce known to me in 

 the peculiar sculpture of the occiput and thorax, which 

 are closely covered with short fiu-rows, running in a longi- 

 tudinal direction, variously confluent and leaving very fine 

 ridges between them. The scutellum is similarly sculp- 

 tured, with a central impressed line. The elytra are
