(See Plate xxiv; figs. 6, 6a.) In the genus Xyloteres, according to Le-conte (Rhynchophora, p. 357), the club ofthe antennae is oval, compressed, and solid,without articulations; the shining corne-ous part extends forwards in a narrow baudas far as the middle, except in ,where it is entirely basal, and the club isindistinctly divided by one round suture ;the rest of the surface is opaque, finelypubescent, and sensitive. The fuuicle iscomposed of two parts as in the two preced- fig. ii^.-xyioteres uvutatus—a. an-iug genera; the first joint is large, and stout i^ed-Gisfier27 ^as usual, the remaining part is about equal in length, forming a pedicel to the club, and is divided by two not wellmarked transverse sutures, thus causing the fuuicle to be 824 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. The eyes are moderately finely granulated and completely head is large, exserted, and in the 3 is deeply concave. The pro-thorax is broader than long, and strongly asperate in front in the 9 , lessin the $ . The tibiae are dilated, finely serrate on the outer edge, roundedat tip, and very feebly mucrouate at the inner angle; the tarsi have thejoints 1-3 rather stout, nearly equal in length ; fourth very small, fifthslender, as long as the second and third united, with simple divergentclaws. The hairs are not serrate or verticillate, as in Pityopthorus, butslender and four species in our fauna are easily recognized : Elytra with well defined striae of punctures, interspaces nearly smooth 2.
