the suture, then to the shoulder, after rounding which, at 

 the very base, it turns down and sends an elongated stripe, 

 parallel, or nearly so, to the exterior margins, sometimes con- 

 tinuing more or less distinctly round the whole elytron, till it 

 reaches the suture near the apex, where there is almost always 

 a testaceous patch on each side of the suture. The sides of 

 the elytra are not quite parallel, being a little expanded behind 

 the middle. Each elytron is deeply punctate striate, as fol- 

 lows, viz., — a single regular row of punctures runs next the 

 suture, then follows a space with two or three irregular rows, 

 then two regular rows, then two or three irregular rows, then 

 two regular rows, two or three irregular rows, two regular 

 rows, and the remainder irregular rows. Margin with a re- 

 flexed border, which is expanded about the middle of the 

 elytron. Pygidium testaceous, rather large, smooth and im- 

 punctate ; upper side of penultimate segment of abdomen 

 finely punctate. Under side of body wholly testaceous ; meso- 

 sternum clothed with long fulvous hairs ; prosternum less 

 hairy, and abdomen with only a few hairs along the margins of 

 the segments, where, as well as on the sides, there are a few 

 punctures Legs testaceous, with a tinge of piceous or brown 

 at the knees, and along the outer margin of the tibiae ; the 

 anterior tibiae have three teeth. The tarsi wholly piceous, long 

 and slender. The claws simple, and of equal proportions. 



This species bears considerable resemblance to A. ustulata 

 (Dej.), Burm. Its system of coloration is the same, and its 

 general form is also very near it ; but it is larger, of a coarser 

 texture, and has the head and thorax punctate, and the elytra 

 punctate and geminato-punctate striate ; whereas in ustulata, 

 the head and thorax are smooth and impunctate, and elytra 

 only very faintly punctate. 



I have received many specimens of this species from Pro- 

 fessor Jameson, in honour of whom I have named it, but I do 

 not find in any of them the thickening of the anterior tarsi, 

 usually seen in the males in this genus. It may be that they 

 are all females, but I have not been able to ascertain this by 

 dissection, in consequence of the interior of the insects having 

 been eaten away by larvae on their way home.
