d " Most nearly related to A. simplex, Sharp, but smaller ; 

 reddish yellow, slightly shining, coarsely punctured and quite 

 sparingly clothed with short grey hairs ; the head rather brownish, 

 with a slight metallic lustre. Clypeus semicircular, with the 

 brown margin a little produced and more elevated in the middle, 

 the surface sparingly transversely rugose and thinly hairy ; 

 clypeal suture a little produced backwards in the middle ; fore- 

 head and vertex covered with coarse short transverse impressions 

 derived from confluent ocellate punctures, thinly hairy, with only 

 the middle of the vertex smooth and shining. Thorax only 

 twice as broad as long, with the front margin produced forwards 

 and the hind margin produced backwards in the middle, the sides 

 dilated in the middle ; the rectangular front angles slightly 

 produced, the very blunt hind angles scarcely rounded, the marginal 

 stria well developed all round, and closely and shortly hairy ; the 

 upper surface with sparse horseshoe-shaped punctures, each 

 bearing a quite short grey hair. Upon the elytra the costse are 

 prominent, the primary rows of punctures regular, and the punc- 

 tures in these and in the intervals coarse, deeply impressed and 

 at the bottom black surrounded with brown ; the upper surface 

 thinly clothed with short hairs, which spring, not from the deep 

 punctures, but from the smooth surface; epipleurae short and 

 narrow, with a narrow membranous margin. Propygidium with a 

 rattier produced hind margin, from which arises a thick fringe of 

 hairs. Pygidium rather closely and finelyjugose, rather prominent 

 before the apex and with longer hairs there. Legs rather strong : 

 front tibiae with three equidistant teeth, middle and hind tibiae 

 each with two obsolete sharp spinose carinae. 



" Length, 9 mm. ; breadth, 4 mm. 



" BENGAL." 



Type in Dr. Ohaus' collection. 



This species is very closely related to A. incurvatus, Ohaus.

"Elongate-oval, rf parallel-sided, 5 a little dilated, rather 

 convex ; above reddish testaceous, with the head and thorax dark 

 brown, the lower surface entirely bright yellow, including legs 

 and antennas, or dark in the middle of the sternum and abdomen. 

 Clypeus semicircular in J and $ , reddish, with the black margin 

 finely reflexed, the clypeal suture straight, the surface covered 

 with moderately close and fine granules, behind which short 

 white hairs arise ; the forehead closely and confluently, the vertex 

 less closely, covered with annular punctures, with greyish-white 

 hairs directed backwards, and isolated longer yellow bristles near
