upper border of the abdomen. The head has the face clothed with yellow pubescence, 

 leaving two bare spots above the clypeus. The thorax has a very slight impression on 

 the front of the disc, and another at the base ; the posterior ridge is distinct but short, 

 close to the margin, slightly curved outwards anteriorly. The elytra are a little 

 narrowed before the middle, wider again behind the middle, and then gradually 

 narrowed to the apex ; the apex of each is furnished with a distinct, but not very 

 acute, tooth near the sutural angle. The prosternal chin-piece is arcuately rounded 

 in front. The prosternum is finely rugose and pubescent, a little widened behind the 

 coxae. The metathoracic episterna are finely rugose, the upper half clothed with 

 yellow pubescence. The abdomen has an oblique stripe of sandy pubescence on each 

 side of the basal segment, and there is a spot on each of the following segments slightly 

 removed from the sides ; the lateral carina of the basal segment is uninterrupted, 

 slightly arcuate, almost rectilinear posteriorly (fig. 19 a).

Elongatus, parallelus, subtus seneus ; capite antice asneo, subtiliter punctulato ; thorace aeneo-fusco, basi paullo 

 angustata, lateribus macula alba ornatis ; elytris sordide cupreo-purpureis, rugosis, maculis sex et strigis 

 quatuor albis ornatis ; femoribus sat incrassatis, tarsis longis.

This species somewhat resembles and is allied to A. femoralis (Tab. V. fig. 22), but 

 is shorter, and has the elytra less gradually narrowed to the apex. The head is lightly 

 impressed in front, finely punctured, dark purple-brown on the vertex, brassy in front, 

 with a longitudinal impressed line, and a slight impression above the clypeus, in which 

 is some whitish pubescence ; the face is not much narrowed at the lower part ; the 

 forehead viewed from above is slightly in advance of the eyes, lightly impressed in the 

 middle ; the head in the only specimen before me is protruding from the thorax as in 

 the type of A. femoralis (this may be a natural character, but I did not consider it so in 

 A. femoralis, and it is not so represented in the figure). The antennae are moderately 

 long, but not so long as in A. femoralis. The thorax is not quite so long as in 

 A. femoralis, finely reticulate and punctured, very slightly narrowed in front, distinctly 

 narrowed at the base ; the disc has a very slight impression in front, and is obliquely 

 impressed on each side behind the middle ; the posterior ridge is obsolete. The 

 elytra are a little narrowed at their middle, of an obscure brownish-purple, closely 

 asperate, with the subcosta only slightly indicated ; each elytron has a small round dirty 

 white spot at the base, then a short streak which almost joins a second spot at the 

 middle (close to the suture), and a third spot at one-third from the apex, joining a 

 streak which is continued to the apex. The prosternal chin-piece is slightly emarginate 

 in the middle. The prosternum is rugose, with the margins raised, obliquely acuminate 

 at the apex. The metathoracic episterna are closely punctured, with a white spot
