Mr. G. Lewis on a new Beetle from Japan. 395 



being equal to one third of tlie whole breadth ; the elytra 

 straight at the base, but otherwise completely oval in outline, 

 sides much dilated and formed, especially in the epipleur^e, 

 like Silpha atrata^ L. ; viewed from beneath they are widest 

 behind the humeral angle, and behind the posterior coxa3 tiie 

 marginal expansion narrows and gradually ceases before the 

 apex. The legs are slender and doubtless vary in structure 

 in the sexes. 



Camioleum loripes^ sp. n. 



Alutaceum, parum nitidum, depressum ; elytris ovatis hand abbro- 



viatis, striato-punctatis, marginaliter dilatatis. 

 L. 4 mill. 



Alutaceous ; disks of the head, thorax, and dorsum, with 

 five terminal joints of the antennas, darker ; the antennte are 

 slender, with the joints relatively longer than in Obphrum 

 simplex, Sh. (to compare them with a very common Japanese 

 species), but otherwise the structure of the articulations is 

 sim.lar; the head uneven between 

 the eyes, with irregular and scat- 

 tered punctures ; punctures smaller 

 and fewer between the antennae ; 

 epistoma smooth ; the thorax mar- 

 gined on all sides with a faint stria, 

 anterior margin bisinuous ; angles 

 rounded off, with the edge behind 

 them feebly crenulate, posterior angles 

 rectangular, sides dilated and slightly 

 narrowed behind, punctured some- 

 what more coarsely than the head, 

 surface uneven, with a fovea before 

 the scutellum and two others, less 

 distinct, placed longitudinally on each 

 side of it near the margin (or they are merged in one, as in 

 the figure) ; the scutellum triangular, with a few small 

 punctures; the elytra complete, dilated along the outer edges, 

 ovate, except at the base ; dorsal area striate-punctate, sutural 

 row of punctures and those next to it most distinct, outside 

 the fifth row the punctures become denser and lose their linear 

 arrangement ; the basal segments of the abdomen are infas- 

 cate. Male: anterior and intermediate tibi?e widely bent; 

 in the anterior pair the inner edge of the tibia is swollen and 

 somewhat angular at the point where the bending ceases. 

 Hah. Main Island, near Kashiwagi, 19th June, 1881. 

 I found two males under some marsh-refuse ; the female is 

 not known to me.
