erect seta?. 



2. (5.) Prothorax much broader than long, the sides stro)igly rounded. 



3. (4.) Anterior tibise stronglj- dilated towards apex; e3'es approxi- 



mated, prominent ; prothorax sti"onglj' constricted at apex.

4. (3.j Anterior tibi* scarcely dilated ; eyes more distant, not 



Ijrominent ; prothorax only slightly constricted at a])ex. 



IS. castus Boh. 



5. (2.) Prothorax almost as long as broad, its sides only moderatelj'^ 



rounded IS. hauliinice, s\). now 



6. (1.) Elytra with rows of erect or suberect setiB. 



7. (8.) Space between the eyes almost as broad as the rostrum.

ACAXTHORRHIXUS CARIXATUS, sp. uov. (Plate LXVII. fig, 12.) 



LoBg. 8g, lat. 3 mm. 



Head short, strongly punctured on vertex, forehead with a 

 broad and deep central furrow which is continued on to base of 

 rostrum. Rostrum about as long as anterior tibia, subcompressed, 

 broadest at base and somewhat narrowed anteriorly, slightly 

 cm'ved ; upper sui-face convex, finely and evenly punctuied 

 throughout, with a short deep central impression at base (con- 

 tinuous with that on head) and a short latei'al impression in front 

 of each eye ; under surface with two longitudinal fitrrows uniting 

 at base, bvit with no prominences ; antennae black, glabrous. 

 Prothorax longer than broad, base rounded and much broader 

 than apex which is truncate, sides subparallel in the basal half, 

 then roundly narrowed and with a constriction at apex ; upper 

 surface almost plane, with very deep, subi'emote punctures 

 leaving a smooth central line ; colour dull black, bare. Elytra 

 jointly sinuate at base, rather broader than prothorax at shoulders, 

 which are sloping, and from there very gradually narrowed 

 posteriorly, the apices separately rounded ; upper surface slightly 

 convex, with regular deeply punctured striae ; the intervals narrow 

 and impunctate, the 2nd, 4th and 6th depressed, the others 

 elevated and carinate ; colour dull black, bare. Legs black, bare, 

 strongly punctured ; femora and tibia? with a fringe of pale setse 

 along their lower edges.

Type in the British Museum. 



A very distinct species owing to the alternate elevation of the 

 intervals on the elytra ; the fringe of setae on the femora is also a 

 character peculiar to it.
