446 Coleopterological Notices, IV. 



The vestiture is pale yellowish in color throughout, the integu- 

 ments in echinus being dark red-brown. In both of the species the 

 prothorax is very obliquely truncate at the sides, so that the head 

 and beak are invisible from above ; the ocular lobes are small. The 

 antennal funicle is 7-jointed and not 6-jointed as indicated in the 

 original description. 



MICROMASTCJS Lee. 



The principal sternal characters of this genus appear to have been 

 in great part misconceived by the author. The beak is moderately 

 thick and perfectly free, the prosternum broadly, feebly impressed, 

 the impression punctate, setose and much wider than the beak, the 

 anterior coxae large, conoidal, prominent and subcontiguous. The 

 intermediate coxa3 are somewhat Avidely separated, the mesosternum 

 between them transversely tumid, densely punctate and setose. The 

 metasternum is only moderately short and is longer than in Acalles ; 

 epimera and episterna both invisible, the third and fourth abdomi- 

 nal segments short. Micromastus is an isolated genus intermediate 

 between Conotrachelus and Acalles. 



ACALLES Schoiih. 



The following is a large species belonging in the neighborhood of 

 nohilis : — 



A. profusiIS n. sp. — Oval, convex, black rather sparsely clothed with 

 large recumbeut scales, without erect setse, the scales dark brown in color but 

 in great part white and denser on the head and basal parts of the beak, in 

 several small isolated spots on the prothorax, on the elytra especially near the 

 sides in basal fourth and in a transverse band near apical fourth, on the 

 femora toward apex and throughout the tibife. //eacZand beak rather coarsely, 

 densely punctate, the latter finely carinate along the middle, rather longer than 

 the prothorax ; antennae inserted at the middle. Prothorax very nearly as long 

 as wide, the sides broadly arcuate, somewhat more convergent toward apex, 

 the subapical constriction fine ; apex broadly arcuate and a little more than 

 three-fourths as wide as the base ; disk coarsely, very densely punctate, the 

 median impunctate carina strong but not entire. Elytra oval, more than twice 

 as long as the prothorax, and, in the middle, nearly one- half wider ; foveas 

 very large, deep and close-set, each with a rather small subquadrate scale. 

 Abdovien coarsely, rather closely punctate. Length 7.5 mm. ; width 3.7 mm.
