liind, each bfu-^al nnjifli' ciulin^' in a sleiulcr proct'ss iliivttrd backward.s ; 

 elytra obovatc, the margins very narrow, lateral, the dink striated, the 

 8tri;e ob.^oletely punctured, the alternate intervals elevat»'d into a sharp 

 line or ridge ; body beneath smooth, black ; legs glossy black. Length 

 8 lines. 



This and the above I received some time ago from W. Macleay, 

 Esq., ^^ithout a precise locality. They are exceedingly well-marked 

 species, the first on account of its flat upper surface with reflected 

 margins to the prothorax and elytra, the second from the absence of 

 humeral angles and the remarkable slenderness of the body above 

 the junction of the elytra and prothorax. In the last species the 

 lateral groove on the prothorax, which on A. WalcJcenaeri is situated 

 at the base, is placed midway between the apex and base ; in A. 

 Macleayi it extends to the middle, but is rather obscurely defined 

 posteriorly. It would perhaps be more correct to regard the epipleurae 

 in A. Macleayi as limited to a portion of the under surface of the ex- 

 panded margin of the elytra exterior to a slightly raised line which 

 may be partially traced, instead of comprehending the whole : it 

 would be more consistent with analogy, although in this case the 

 epipleurae would be all but confounded with llie elytra. 



Atryjphodes erraiis. 



A. niger, nitidus ; prothorace modice convexo, glabro, marginibus an- 

 gustis ; elytris prothorace angustioribus, striatis. 



Hab. Queensland. 



Black, shining ; head with a few foveas in front (as well as the sul- 

 cations common to the genus) ; prothorax moderately convex, rounded 

 at the sides, the margins narrow, latero-basal groove very short ; elytra 

 narrower than the prothorax, slightly convex, the shoulders obsolete, 

 the disk regularly striated ; body beneath and legs glossy black ; the 

 tarsi covered with golden-brown hairs. Length 7 lines. 



Similar to A. Walclenaeri, but glossy, not opake, and a narrow mar- 

 gin to the prothorax, which is also rather broader than the elytra. 



Atryphodes aratus. 

 A. niger, indumento fuscescente tectus; prothorace utrinque foliaceo; 

 elytris subplanatis, inaequaliter striatis, lateribus rellexo-niarginatis, 

 humeris distinctis. 

 Hab. Queensland. 



Closely allied to A. Macleayi, but covered with a brownish liluiy 

 crust, the elytra less flattened, and the striic irregular, the intervening 

 lines being somewhat flexuous, the fifth from the suture more elevated 

 than the rest, and the two or three outer broken up into numerous ob-
