1158 COLEOPTERA 



This species closely resembles .1. clieescmani (No. 1404). In 

 both there are about seventeen elytral striae, only eight or ten of 

 which usually touch the base, the interstices are narrow and convex, 

 and very sparingly punctured, and a few very slender elongate hairs 

 are distributed over the surface : there, however, the likeness ends. 

 In A. viiniatiim the head is more rugosely punctured, with two small 

 frontal impressions. The thorax is considerably longer, being 

 evidently longer than broad, its sides are more slightly (gently) 

 curved in front and narrowed behind, and the lateral margins are a 

 good deal thicker, especially near the front, and more raised. The 

 basal two segments of the abdomen are longitudinally impressed. 

 The middle coxce rather further apart. 



Length, 5^ ; breadth, 1|- lines. 



I am indebted to Mr. A. T. Cavell for my specimen, which was 

 found at Boatman's, near Eeefton. 



2055. A. gratiosiira, n.s. Bobnst, ovate-oblong, a little convex 

 transversely and somewhat arched longitudinally ; shining, coppery- 

 black, slightly rufescent ; last joint of palpi and first of antennae 

 piceous, the other joints pale-ferruginous. 



Head short, immersed up to eyes, irregularly rugose. Antennce 

 with fulvous pubescence ; third joint nearly twice the length of 

 fourth. Thorax transverse, deeply emarginate at apex, widely 

 sinuate at base, broadest at the middle ; sides gradually narrowed 

 and slightly curved towards the obtusely prominent anterior angles, 

 more abruptly, and a little sinuously, narrowed behind, posterior 

 angles rectangular, resting on base of elytra ; lateral margins thick, 

 the basal and apical much finer ; a little uneven above, side channels 

 broad and more or less distinctly wrinkled transversely, the rest of 

 its sculpture impossible to define briefly, consisting of linear im- 

 pressions enclosing areas of irregular form. ScuteUiim broadly 

 triangular, smooth. Elytra wider than thorax at base, considerably 

 narrowed posteriorly, shoulders obliquely rounded, lateral margins 

 distinct ; tliere is a sutural row of fine punctures on each, the rest 

 of the punctuation is seldom regular, the otlier sculpture consists of 

 irregular, sometimes raised, spaces, and depressions. 



Underside shining, black, finely sculptured ; pleurae rather 

 coarsely rugosely punctated ; head and flanks of prosternum irregu- 

 larly wrinkled. 



The elytral sculpture has some resemblance to that of A. bullatum 

 and A. intricatum, but is even more troublesome to describe minutely. 

 It is the finest species I have seen, though I have several Aus- 

 tralian. 



Length, 8^ ; breadth, 3f lines. 



Boatman's, near Eeefton. Two examples, discovered bv Mr. 

 A. T. Cavell. 



2056. A. turgidulum, "-s. Convex, without superficial in- 

 equalities, shining ; slightly infuscate bronzed-black, tarsi and 

 anteimip piceous, claws red.
