184 Capt. T. Broun on new 



broadly, but not deeply, impressed near each side. Antennal 

 cavities large at the point of insertion, the groove along the 

 inner side of the eye rather narrow. 



This genus may be placed near Heterargus and Tarphius. 

 The eyes are larger than those of the former, the mentum is 

 much smaller, all the coxte are less widely separated, and the 

 prosternum and epipleurse differ. 



Proimyhius ruficornis^ sp. n. 



Ohlong^ convex, covered with greyish-yellow sappy matter, 

 rufo-fuscous ; antenna^, tarsi, and palpi yellowish red ; legs 

 infuscate. 



Head small, immersed nearly to the eyes, about half the 

 width of the thorax, with a few small granules and fine yellow 

 set£e,the prominences over the antennal insertion not extending 

 laterally beyond the eyes. Antennce short; first joint thick, 

 only its extremity visible from above; second stout, hardly 

 longer than broad ; 3 to 9 slender, third distinctly longer than 

 fourtli, 5 to 9 bead-like, the ninth scarcely larger than the 

 eighth ; club pubescent, large and compact, its basal joint 

 large and transverse, thrice the breadth of the ninth, the 

 terminal slightly longer than the basal one, but hardly as 

 broad as that is. Thorax transverse, its sides somewhat expla- 

 nate, but little curved, not serrate, abruptly contracted or 

 notched close to the base ; apex medially rounded, with a 

 sinuosity inside each of the obtuse angles ; the surface uneven, 

 with five impressions and intervening elevations, its sculpture 

 granular. Elytra oblong, of the same width as the thorax, 

 the apical portion narrowed and nearly vertical ; on each 

 elytron there is a moderatel}' elongate basal elevation, in line 

 with this there are two nodosities, the larger one is on the 

 top of the apical declivity, there is another series near the 

 side ; between the suture and the side there are four series of 

 closely-placed punctures, the interstices are more or less 

 transversely rugose. Legs rather short ; tihi(B but little 

 curved, with fine yellow sette, like those on the body. 



Underside rather plane, rufo-fuscous, with granular sculp- 

 ture and fine seta?. Abdomen with deep broad sutures. The 

 side of the prosternum bears five or six denticles which are 

 not visible above.

Ohs. No. 1167 may be placed in this genus ; the tarsi, 

 however, are more elongate and slender, and the eyes arc 

 larger and more prominent.
