[The ground color of thi.s species is very pale red, the thorax is 

 quadrimaculate, the umbone and two spots on the elytra are l)lack, 

 one or both sometimes wanting; the pubescence is longer and denser 

 than in any of the other si)ecies. Annulafm is the older name, but 

 synonymy was made by the author himself for reasons not stated, 

 but probably on account of the name being preoccu})ied.] " Ham."

[The two species of this genus in our fauna may be thus separated : 



Sides of elytra rounded flaiiiiiiata. 



Sides of elytra vertical ain«ena.

Black, hispid with tine erect black hairs, two oblicpie lines on the 

 head, a stripe on each side of the thorax and the margins of the 

 elytra nearly to apex yellow. Var. ardens is more hispid, more 

 coarsely punctured, with the yellow of the margin extending to the 

 middle of the disc. The antennje are hispid from base and annulate 

 from the fourth joint.] "Ham." 



[A. ainceua n. sp. — Length 4.5 mm. = .18 inch. 



Elongate, shining black, anteunaj shorter than the body, with long flying hairs, 

 annulate at the incisures, scape and third joint subequal, fourth much shorter, 

 outer joints gradually shorter. Head wider than long, short, a little retracted, 

 front convex, with an exceedingly fine median line, not impressed between the 

 antenna', surfac^e white, and with the thorax clothed densely with extremely fine 

 short white pubescence. Thorax a little wider than long, cylindrical, a fuscous 

 spot near margin liehind each eye, at base each side of middle two large denuded 

 triangular spots black. Elytra parallel till near apex, then suddenly obtusely 

 rounded, disc flat, limited each side bj- a sharp ridge (humeral carina) parallel 

 with the suture, sides deep, vertical, divided into two broad striie by a subhumeral 

 carina, internal (upper) with two rows of close-set round punctures, punctuation 

 of the outer (lower) which is the wider confused, marginal stria very narrow, 

 impunctate, obliterated in front ; disc moderately finely punctured in rows, which 

 are confused near the suture, each puncture bearing a very fine semi-erect black 

 hair; underside with sparse exceedingly fine siiort pubescence, alutaceous, shin- 

 ing; first joint of hind tiirsi scarcely longer than the second. 



This is a pretty little species with white head and thorax spotted 



with black, and shining black elytra. The vertical and striate sides
