1256 COLEOPTERA 



form, rather slender, but a good deal stouter than the third, the three 

 terminal joints forming a well-marked rather large club ; the ninth 

 longer than broad, gradually broader from base to apex ; tenth not 

 quite so long as broad ; terminal joint longer than tenth, but not so 

 long as ninth. Thorax about as long as broad, much narrower from 

 the base to the front. Carina well separated from the base, gently 

 curved, turned forwards at the sides, forming an obtuse angle ; the 

 surface densely, evenly, and finely rugose. Elytra substriate, the 

 strias consisting of regular series of very distinct punctures. Legs 

 and tarsi black, more or less pubescent at the knees. 



Although closely allied to A. incertus and A. vates, this is dis- 

 tinguishable at a glance by the uniform black colour.

2213. A. COILCOlor, n.s. (Sharp ; Trans. Roy. Dub. Soc., 1886,

 corporis dimidii longitudine, clava obscura. 



Long., 4mm. 



This agrees in most particulars with A. inornatus, but differs in 

 the more pallid colour, and has also shorter, more slender antennae ; 

 the thorax, too, is a little less elongate. In sculpture and all other 

 characters the two species are very similar.

2214. A. ObtUSUS, n.s. (Sharp ; Trans. Boy. Dub. SoC., 1886, 

 p. 435.) Subcylindricus, nigro-fuscus, squamulis variegatis vestitus ; 

 antennis pedibusque fusco-rufis, illis corpore brevioribus ; prothorace 

 carina transversa ad basin per-propinqua, angulis posterioribus haud 

 acutis. 



Long., 4mm. 



This is remarkably similar to Etnalis spinicollis in appearance, 

 but differs in important structural characters, so as to stand sys- 

 tematically intermediate between the species named and A. huttoni. 

 The antenna, are slender, a good deal shorter than the body, the 

 basal joint much exposed ; third joint very slender, elongate, not at 

 all clubbed at the apex ; 4-8 each infuscate at the apex ; ninth 

 broader from base to apex, slightly longer than broad ; tenth shorter, 

 terminal joint obtuse, about as long as broad. Rostrum short and 

 broad. Eyes moderately large, emarginate, but not deeply so in 

 front; the surface very densely and minutely sculptured, feebly 

 pubescent. Thorax not so long as broad, only a little narrower in 

 front, the sides scarcely sinuate in front of the base ; the carina 

 straight, extremely near the base ; it is not continued upwards along 

 the sides, but is scarcely prominent at the angles ; the surface is 

 covered with fuscous scales or hairs, and has a large patch of white, 

 or pallid-ochreous colour, on the basal portion of each side. Elytra 

 not elongate, behind the base a little transversely depressed, with 

 series of punctures, which are quite obsolete on the apical portion, 

 the external ones being more distinct ; they are covered with gri- 

 seous, fuscous, and nearly-black hairs or pubescence, in an irregular
