Genera and Species of Coleoptera. 341 



Some individuals of this species are much darker than others, and 

 the spots more confluent. 



Abrijna vomicosa. 



A. robusta, grisescente pilosa, maciilis nigi-is irrorata ; scutello grisescente ; 

 tarsorum articulis duobus basalibus albis. 



Hab. Cambodia. 



Pitcliy-black, ■with a short pale-gi'eyish (or inclining to yellow) pile 

 sprinkled with numerous small black spots ; head rather broad in fi-ont, 

 the spots irregular and confused ; prothorax subtrausverse, with three 

 obtuse tubercles on the disk (2.1), the posterior divided by a deeply 

 impressed longitudinal line, the two lateral teeth very distinct ; scu- 

 tellum greyish ; elj-tra rather short, broadest at the shoiilders, slightly 

 depressed behind the scutelhmi, clothed with a pale-greyish pile, 

 slightly mottled with a darker grey, and thickly sprinkled with small 

 black spots, which are formed almost entirely by the pimctm-es ; an- 

 tennae scarcely longer than the body, the basal joint greyish, spotted 

 with black, the rest black, except the second and bases of the succeeding 

 ones to the ninth inclusive which are ashy- white ; eyes and mandibles 

 dark brown ; legs greyish, spotted with black, the tarsi black, the two 

 basal joints white; body beneath covered with a coarse gi-ejish pile, 

 the sides of the abdomen spotted with black. Length 10 lines. 



The difference between this species and the last is greater than 

 might be imagined from a comparison of the two descriptions, but it 

 may be rendered more obvious by remarking that, while the spots are 

 larger in -4.p«rcZa?«s,they have invariably around the puncture, which 

 forms the centre of each, a circle of black pile, and that these spots 

 often become confluent, having a more or less patchy appearance ; 

 but in A. vomicosa the spots are confined chiefly to the punctures, 

 which then almost entirely constitute the spots ; the two basal joints 

 of the tarsi, nearly of a pure white, offer a remarkable contrast to the 

 deep black of the remainder. 



From Ahrijna, as originally proposed by Mr. Newman, I think it 

 wiU be necessary to separate those species which approach Dorcadion 

 in form and, except very partially in one or two of them, in the 

 total absence of pubescence. For these I propose the term "A_pro- 

 phata," with the following characters : — 



Apeophata. 



Head rounded, not dilated below the eyes in the male, the vertex and 

 front very convex. Eyes deeply emarginate. Antennae scarcely longer 

 than the body, not arising from tubercles, the basal joint short, slightly 

 incrassated upwards, the third joint longest, the fourth neai-ly as long, 

 the remainder shorter and subequal. Prothorax more or less quadrate.
