hind, each basal angle ending in a slender process directed backwards ; 
elytra obovate, the margins very narrow, lateral, the disk striated, the 
strize obsoletely punctured, the alternate intervals elevated 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., without 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. Walckenaeri 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 epipleurz 
in A. Macleay? 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 
epipleuree would be all but confounded with the elytra. 
Atryphodes errans. 
A. niger, nitidus; prothorace modice convexo, glabro, marginibus an- 
custis; elytris prothorace angustioribus, striatis. 
Hab. Queensland. 
Black, shining; head with a few fovez in front (as well as the sul- 
cations common to the genus); prothorax moderately conyex, 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. Walckenaeri, 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, ineequaliter striatis, lateribus reflexo-marginatis, 
humeris distinctis. 
Hab. Queensland. 
Closely allied to A. Macleayi, but covered with a brownish filmy 
crust, the elytra less flattened, and the strie irregular, the itervening 
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-
