This remarkable insect bears a superficial resemblance 

 in general form to O. insccatus ; it will probably have to 

 be separated as a distinct genus ^N\\QuOx7jteli are jn'operly 

 studied. Antennte long and stout, gradually thickened 

 from the 4th to the 10th joint, the three basal joints red, 

 the others dusky; from the 4th to the 10th joint, each is a 

 little longer and stouter than its ]^redecessor, the 10th joint 

 about as long as broad. Head slightly broader (in the male ?) 

 than the thorax, or slightly narrower (in the female?); 

 the sides very thick and convex, so that the fi-ont appears 

 excavated ; at the back of this depressed part are two 

 longitudinal elevations ; the mandibles are reddish, elon- 

 gate and conspicuous. The thorax is nearly as broad as 

 the elytra, very transverse ; it is punctate-rugose, with two 

 strongly elevated lines along the middle, and also with 

 another rather shorter elevation on each side of these ; the 

 elevated parts are smooth and shining, the sides are finely 

 crenulate. The elytra are but little longer than the 

 thorax, pale, shining yellow, rather sparingly and finely 

 l)unctured. Legs pale yellow, anterior tibia3 long and 

 slender, distinctly narrowed at the extremity. 



Three sjjecimens. 



169. Oxytelus Icevior, n. sp. Fusco-testaceus, niti- 

 dulus, antennarum basi pedibusque pallide testaceis, ely- 

 tris testaceis ; parcius strigosus, thorace trisulcato. Long. 

 H lin. 



An aberrant species of the sculjitus group. Antenna? 

 rather long, the four basal joints yellow, the others clouded; 

 1st joint about as long as the four following together, 4th 

 joint very minute, 5th intermediate in size betAveen 4th 

 and 6th, 6 — 10 about equal to one another, not transverse. 

 Head of a reddish colour, distinctly but not coarsely 

 sculptured, the eyes not reaching to the hinder angles.
