in the 5th-7th strife where the punctures are exceedingly large; 

 interstices much narrower than punctures, convex, distinctly but 

 sparsely and irregularl}^ punctate. Metasternwm with a distinct 

 depression in middle, nari^owing to the sides. • ^6f?o?new irregularly 

 punctate, basal segment raised above and almost twice the length 

 of 2nd, intercoxal process with a transverse sulcus on each side. 

 Length 3^, rostrum 1 (vix); width 2g; variation in length 3^- 

 5 mm.

 (Acalles cribricollis, Pasc.) 



Upper surface and pectoral canal clothed as in preceding. 

 Abdomen and sterna with a few white scales almost hidden in 

 punctures. 



Head densely and moderatel}' strongly punctate, punctures 

 larger between eyes than else v/ here. Rostrum wide, feebl}'^ but 

 noticeably incur^'ed to middle, irregularly punctate, punctures 

 forming lateral grooves. Scape short, scarcely longer than two 

 basal joints of funicle, inserted nearer base than apex of rostrum 

 and not extending to apex. Prothorax strongly transverse: with 

 dense large punctures. Elytra subcordate, wider than prothorax 

 at base; striate-punctate, punctures large, round or elliptic, distant 

 towards the sides, moderately close towards suture; interstices 

 rounded, much wider than . punctures, with minute scattered 

 granules and without punctures. Metasternum with a deep 

 impression on each side. Basal segment of abdomen almost twice 

 the length of 2nd, with large punctures at sides but small ones 

 in middle, intercoxal process with a deep transverse sulcus on 

 each side; 2nd segment with from eight to ten very large round 

 punctures or foveas forming a transverse row, and about five 

 marking its sutui'e with 1st ; intermediates with a few minute 

 punctures. Length 5 (vix), rostrum ^ \\, ^ IJ; width 3^ mm.

Allied to memnoiiius, but with comparatively smaller and less 



regular elytral punctures, the interstices granulate instead of
