 elongata basali, exceptis) nigro-fuscis ; prothorace fortiter 

 transverso, Itevigato, canaliculate, marginibus lateralibus 

 late reflexis fortiter rotundatis mox ante angulos posticos 

 vix sinuatis, his acute rectis fere subdentiformibus ; elytris 

 subtiliter striatis, striis subtiliter (nullo modo obsolete) punc- 

 tulatis, interstitiis planis (marginali excepto) Isevigatis.

 This species does not seem to vary in colour and markings, — 

 but some varieties of the preceding species in which the suture 

 is pallid anteriorly are a good deal like it. It appears to be 

 constantly as small as the smallest specimens of A. inornatits, 

 and is a shorter, wider-looking insect. Its elytra are distinctly 

 ovate (i.e., at their widest behind the middle) while those of 

 inornatus are elongate-oval and are scarcely if at all wider 

 behind the middle than at a short distance behind the base. 

 The hind angles of the prothorax are very distinctly sharper in 

 the present species, the strise of the elytra are very much more 

 distinctly punctulate, and those near the suture are scarcely 

 marked in front (being represented by rows of line punctures), 

 while the interstices of the strise are flatter, being absolutely flat 

 in front and even towards the apex scarcely less so ; the cariniform 

 external edge of the 7th stria does not extend so far forward on 

 the elytra,
