A beautiful little species; the type has the front femora 

 pale, so in my table would be associated with C. facialis, from 

 which it differs in the sharply denned punctures of elytra 

 and in many details of colour, in particular the blue elytra 

 and red head ; regarding a second specimen (having somewhat 

 infuscated front femora) as having entirely dark legs, it 

 might be associated with C. pallidifrons (although the elytra 

 are not metallic), from which it differs in its entirely pale 

 head, sharper elytral punctures, etc. From the description 

 of C. azureipennis it differs in the entirely black abdomen, 

 black scutellum, front legs partly pale, and pale basal joints 

 of antennae. 



Carphurus semirufus, n. sp. 



9 . Black ; head (except for a vague infuscation behind 

 each eye), four basal joints of antennae, prothorax, tibiae, 

 and tarsi reddish. With long, dark hairs, and sparse, pale 

 pubescence. 



Head gently convex between eyes, a shallow transverse 

 impression in front ; with minute punctures, becoming larger 

 near eyes, base transversely strigose. Antennae moderately 

 long, third to tenth joints rather strongly serrated, eleventh 

 almost twice the length of tenth. Prothorax slightly trans- 

 verse, sides strongly rounded, apex slightly wider than base; 

 with a few scattered punctures. Elytra short, scarcelv twice 

 the length of prothorax; with fairly dense and rather sharply 

 defined, but small punctures, becoming still smaller pos- 

 teriorly. Length, 4 mm.

At first glance the type appears to be a Helcogaster, but 

 the sharply defined elytral punctures, and serrations of 

 antennae, should exclude it from that genus. Regarding the 

 species as belonging to G of my table of Carphurus, it would 

 be associated with C. triimpressus, which, with others of G, 

 have been transferred to Balanophorus (the type has combless 

 front tarsi so cannot belong to that genus) ; but regarding it 

 as belonging to GG, it would go with C . facialis, which has 

 elytra longer, more metallic, and with larger punctures,, part 

 of head black, etc. ; the elytra are shorter and with less con- 

 spicuous punctures than in C . basiventris, the head is wider, 

 and abdomen entirely black. 



Carphurus compsus, n. sp. 

 d . Flavous; six apical joints of antennae and part of 

 the preceding one, and a large blotch on elytra blackish. 

 With fairly numerous dark hairs, and in places with very 

 sparse, ashen pubescence.
