1386 COLEOPTEEA 



these, though not themselves conspicuous, cause a rough-looking 

 appearance. 



Eostrum as long as thorax, parallel, slightly rufescent, apparently 

 rather closely punctured. Thorax narrowed towards the front, 

 only slightly constricted there ; the space along the middle seems 

 plane, owing, no doubt, to the absence of the erect setae seen else- 

 where. Scntellum absent. Elytra widest, and most convex, near 

 the middle, narrowed to the wadth of the thorax at the base ; they 

 bear many erect squamiform setae, but the sculpture cannot be seen. 



Much narrower than A. mimus ; the pair of posterior crests in 

 iiiarked contrast to the prevailing dark colour, and the straight- 

 sided, almost wholly squamositate rostrum distinctive. 



Length (rost. excl. ), 1 ; breadth, i line. 



Moeraki. Mr. Sandager. Unique. 



2418. A. Sympedioides, n.s. SuhoUong, piceous, densely 

 and evenly covered with pale-brown depressed scales, and bearing 

 also a few slrort scale-like setas, which, however, are not conspicuous 

 except near the sides, the apex of the thorax, and at the top of the 

 hind declivity in line with the fifth interstices. 



Rostrum rather longer than the thorax, very slightly narrowed 

 towards the middle, arched, rather closely punctate, a little rough- 

 looking, squamose behind. The scrobe is deep, extending from the 

 middle to the lower and front part of the eye. Scape gradually 

 thickened, with a few coarse decumbent yellow setae. Fimiculus 

 elongate, with some grey hairs, basal joint elongate, the second 

 nearly as long, 3-7 differ but little, seventh moniliform ; club 

 large, oblong-oval. Thorax abruptly contracted in front for nearly 

 half its length, the basal portion a little depressed, with a short 

 indistinct carina. Scutellnm invisible. Elytra of nearly the same 

 width as the thorax, being only slightly broader near the hind 

 thighs, convex, appearing depressed at the base, with series of coarse 

 but not closely-placed punctures. Legs clothed like the body. An- 

 tenna and tarsi dark-red. 



This much resembles Sympediiis vexatus. It is much smaller, 

 the thorax is not so suddenly narrowed in front, the tarsi are shorter 

 with a narrower penultimate joint, and the femora are not distinctly 

 dentate below. The presence of small squamae causes the rostrum 

 to appear asperate in front. 



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



Moeraki. I have seen but one specimen, which was sent to me 

 by Mr. Sandager.

2419. E. elegans, ''-s- Suhdepressed, elongate, slender, sub- 

 opaque, red, the elytra darker on some parts, antenn© and tarsi 

 fulvescent ; clothed with bright- yellow setae, on the thorax they are 

 decumbent, quite hair-like, and elongate ; on the elytra they are
