from the base to the insertion of the antennee, tlie sulci coarsely punctate, the intervals 

 with fine scattered punctures hardly larger than those on the head. Antennm 

 testaceous brown, joint 2 of the funicle slender at the base and rather abruptly 

 clavate, joint 7 clothed with rather dense grey pubescence. Prothorax subconical, as 

 long as its basal width, broadest at the base and strongly narrowed anteriorly, the sides 

 gently rounded, strongly and closely punctate throughout, with a curved transverse 

 impression about the middle. Elytra with regular sulci containing subquadrate fovete 

 which disappear near the apex and at the sides, the intervals not broader than the 

 foveas, convex and bearing indistinct minute granules. 



Length 11, width 4^ mm.

Described from a single specimen. 



The four other species of Aclees recorded from New Guinea may be distinguished 

 by the following characters : — In A. crihratus Gyl., the prothorax is much longer than 

 broad and is tuberculate at the sides, and the rostrum has no central furrow ; 

 A. (jyllenhali Pasc, which is much larger (18x7 mm.), has the thorax and rostrum 

 somewhat similar, but the elytra bear shallow striee containing rows of granules 

 and the plane intervals are much more distinctly granulate ; in A. ])orosus Pasc, the 

 central furrow of the rostrum is confined to the extreme base, the prothorax is broader 

 than long, and the elytra are very differently sculptured ; finally, in A. granulosus Fst., 

 the striaB on the elytra are comparatively finely punctate, while the broader, flatter 

 intervals bear distinct rasp-like granulation. 



Aclees gillenhali.
