1236 COLEOPTERA 



humeral angles ; dorsum somewhat flattened, bordered near each 

 side by a Ime of setae extending from near the base to bej-ond the 

 top of the hind slope, the sides outside these setae punctate ; the 

 disc itself, and the apex, apparently without punctures, but having, 

 near the base, about ten tubercles disposed in two rows along the 

 suture. Tarsi short, third joint widely expanded and lobate. 



Metastermim short ; basal ventral segment depressed, squamose. 



Length (rost. excl.), 3 ; breadth. If lines. 



Mokohiuou Island. One individual, from Mr. P. Sandager. 



2174. A. maritimus, n-s. Convex, quite oval ; covered with 

 small yellowish-grey scales and setae, some longish ones form four 

 indistinct crests nearly in line with the hind thighs ; body obscure- 

 black, tarsi and antennae pitchy-red. 



Distinguishable from A. veratrus by its narrower /or?«, unflattened 

 elytral disc, paler clothing, less rough-looking aspect, owing to the 

 finer and shorter setae, and by the elytra being regularly striate- 

 punctate (the eight or ten minute tubercles are clustered near the 

 scutellar region) . 



Metasternwii short ; first abdominal segment very large, plane in 

 front, the second convex, indistinctly bicristate, third and fourth 

 very short. The frontal portion of the rostrum obsoletely marked 

 off. Pectoral canal extending to the raised border of the raeso- 

 sternum. The anterior narrowed portion of the tliorax more than 

 half the whole length, much longer than in A. veratrus. 



Length (rost. excl.), 2|- ; breadth, 1^ lines. 



I have two specimens, both sent by Mr. Sandager from Moko- 

 hinou. 



2175. A. cryptobius, n-s. Oval, convex; pitchy-red, covered 

 with small, depressed, yellowish-grey squamae. 



This species may be mistaken for A. maritivms ; it differs, how- 

 ever, by being rather broader ; by the absence of set(r on the body, 

 though present on the legs ; the tarsi are more hispid above ; the 

 rostrum is more finely and quite distantly punctured ; the small 

 tubercles extend along the suture of the elytra, which, moreover, 

 are more obviously striate-punctate. 



The basal two segments of the abdomen are almost quite flat, 

 the second being much larger than in A. maritivms, being in fact 

 nearly as large as the first instead of about half that length, and in 

 place of the straight suture between the two it is here quite oblique 

 towards each side. The contracted apical portion of the thorax is 

 half the entire length. 



Length (rost. excl.), 2^ ; breadth, 1^ lines. 



Two examples were found amongst the roots of a Mesembry- 

 anthemum by Mr. Sandager, at Mokohinou Island. 



2176. A. ingens, n.s. Oviform, hroa,d ; squamosity variegate, 

 pale-brown, blackish, and pale-testaceous; that of the last-men- 

 tioned colour covers the basal half of the beak, the head, a line near
