702 COLEOPTERA 



Lyperobius (p. 444). 



1236. L. carinatUS, n.s. Body sub-ovate, moderately convex, 

 pitchy-black, slightly glossy, and sparingly squamose. 



Rostrum robust, impressed in front of the eyes, and not very closely 

 punctured. Head convex, more finely punctate than the snout, the occi- 

 put densely clothed with elongate griseous scales ; eyes narrow. Antennas 

 piceous, hispid; the scape a little thickened apically; the two basal 

 joints of the funiculus nearly equal, the second, however, rather shorter 

 than the first, the others almost moniliform ; club ovate, finely pubescent. 

 The prothorax about as long as broad, scarcely convex, somewhat curved 

 laterally, sinuously, but not greatly, narrowed behind, with rectangular 

 posterior angles and contracted apex ; its surface is uneven ; the disc, 

 except an elongate space in front of the middle, is sparsely punctate, 

 the punctation towards the sides much coarser and rugose, and bearing 

 the greater portion of the squamosity. Elytra oviform ; each bears four 

 obvious, almost smooth, costae ; the first united at the apex to the fourth, 

 which, though distinct near the point of junction, becomes quite obsolete 

 at the side, the intermediate abbreviated ; the suture also is smooth ; the 

 interstices are scaly, and each contains two rows of punctures separated 

 by a slightly raised interval. Under-side more shining than the upper, 

 sparingly and finely punctured, and, like the legs, bearing fine greyish 

 scales. 



Resembles the typical species, but easily distinguished therefrom by 

 the carinate elytra and scaly covering. 



Length (rost. excl.), 9 lines ; breadth, 4. 



My specimen came from J. D. Enys, Esq., F.G.S. 



Hygrochus. 



Nov. gen. 



Rostrum robust, triangularly excavated at apex, where it is slightly 

 dilated ; scrobes oblique, very large, extending from the apex to the lower 

 margin of the eyes, gradually and considerably expanded posteriorly, 

 quite distinct from above; the true antennal cavity is linear and along 

 the lower part, the upper is less deeply hollowed. Head short, immersed 

 to within a short distance of the eyes. Antenna rather short, scape shorter 

 than the funiculus, attaining the back part of the eye, flexuous, gradually 

 incrassated ; funiculus 7-articulate, the two basal joints of almost equal 

 length, the second more slender than the first; third intermediate in 

 length between the second and fourth, obconical; joints 4-7 sub-monili- 

 form ; club ovate. Eyes nearly round, rather small but prominent, dis- 

 tinctly facetted. Prothorax cylindrical, a little dilated before the middle, 

 base and apex truncate, widely, but not deeply, emarginated near the 

 eyes. Scutellum small, broadly triangular. Elytra oblong-ovate, scarcely 

 exceeding the thorax in width at the base, a good deal widened behind 

 the oblique shoulders, sides sub-parallel, narrowed and declivous pos- 

 teriorly. Legs stout; femora unarmed; tibiae flexuose; tarsi normal, 

 rather short. Anterior coxce sub-contiguous, the other pairs more distant. 

 Sternum and abdomen formed as in Emp&otes. 



This genus should be located near Empcsotes. The scrobes are curious. 

 The only representative was found on moist ground under wood.
