broader than thorax, their obtusely porrect humeral angles clasp the 

 thorax, the sides are a little uneven, rounded, and rather abruptly narrowed 

 posteriorly, the declivity is nearly perpendicular ; they are very coarsely 

 seriate-punctate, much more finely behind ; there is a slight elevation 

 each side of the scutelhim, and there are 4 small crests on top of the de- 

 clivity which are absent in my specimen, the male. 



Scape implanted at or just before the middle, reaching the eye, 

 slightly flexuous, gradually thickened, glabrous. Funiculus sparingly 

 and finely setose, 2nd joint of about the same length as the basal, 

 joints 3-7 successively thickened, so that the last is as broad as the 

 subovate club, the basal joint of which is longer than the following two 

 combined. 



Femora long and stout, subangulate and minutely dentate in the male, 

 less so, the anterior not at all, in the female. Legs sparsely setose. Tarsi 

 glabrous above in the male, with yellow hairs in the other sex, their 3rd 

 joint moderately dilated and lobate. Scutellum present, tilted forwards. 

 In the female the rostrum is more finely punctate. 



The solitary mounted specimen in my possession does not permit 

 a thorough examination of the sternal structure ; had another been 

 available this species, together with 2942 and 2951, would have been 

 placed in a new genus, the more salient characteristics being the pre- 

 sence of the scutellum, porrect humeral angles, and indefinite femoral 

 armature. 



Length (rostrum exclusive), 4J mm. ; breadth, 2| mm.

Xenacalles Broun gen. nov. 

 89. Xenacalles squamiventris sp. nov. 



Opaque, piceous, covered with pale-brown or tawny depressed squamae 

 and erect occasionally greyish ones, which sometimes form a pair of small 

 crests on the suture at the summit of the posterior declivity ; just in 

 advance of these there is a large transverse somewhat diamond-shaped 

 fuscous spot ; rostrum piceous or reddish, antennae and tarsi ferruginous 

 or fulvescent. 



Rostrum as long as thorax, finely punctate, squamose near the base. 

 Scape medially inserted. Thorax slightly longer than broad, gradually 

 narrowed anteriorly, not constricted in front, rounded and bearing erect 

 setiform squamae there, its punctation concealed by the scales, some of 

 which are fuscous. Scutellum distinct. Elytra slightly broader than 

 thorax at the base, rather wider before the middle, evidently narrowed 

 posteriorly, seemingly punctate-striate ; the striae more distinct along the 

 declivity than on the disc. Legs elongate, thickly squamose ; tibiae usually 

 fuscous near the middle. 



Underside densely covered with tawny scales, and with some almost 

 white ones on the basal two ventral segments and basal half of the femora ; 

 the 3rd and 4th segments, singly, more than half the length of the 2nd. 



The following characters differentiate this species from Acnlles : Scutel- 

 lum distinct. Pectoral canal extending to front of metasternum, deep 

 there. Tarsi with hairy instead of spongelike soles. Metasternum not 

 longer than 2nd abdominal segment. Body elongate, subfusiform.
