Gen. ATIMUS. 

 Mentum with a deep median notch without trace of any median 

 tooth, lateral lobes straight at base and inwardly diagonal from the 

 median part to the apex, which is sharp ; ligula triangular, trun- 

 cate at tip ; paraglossae slender, disunited from near the tip and 

 much longer ; last joint of palpi fusiform, truncate at tip ; antennae 

 reaching a little below the shoulder, the three basal joints glabrous, 

 the others from the fifth upwards subcylindrical and twice as long 

 as broad ; head and prothorax of Abacetus ; elytra elongated, parallel, 

 striate, the first stria sinuate inwardly at the base to admit of an 

 accessory stria between the first and the second, and reaching from 

 the base to one-fifth of the length, third interval with a median 

 puncture ; legs of Abacetus. 



Atimus crenato-striatus. 



Deep black, shining ; palpi, basal joints of antennae and legs 

 piceous black ; head smooth, with a short, moderately deep curved 

 frontal impression ; prothorax moderately ampliate laterally from 

 apex to past the median part, and gradually narrowed from there to 

 the base, which is a little narrower than the apex, median longi- 

 tudinal line well defined and reaching from base to apex, the trans- 

 verse lines being obliterated, no outer marginal groove, the basal 

 lateral one is straight but not so deep as in Abacetus, and in the 

 posterior angle there is on each side a shorter and shallower but 

 very distinct groove ; elytra very little broader than the prothorax 

 at base, elongate, parallel, depressed, sinuate behind, striate, the 

 striae deeply and closely punctured, intervals smooth and very 

 slightly convex, the third one with a median puncture. Length 

 12|- mm. ; width 4J~4^ mm.
