158 Arthur M. Lea : 



Tliere appear to be no special laasculine features. The male 

 is smaller, usually much smaller, than the female, somewhat 

 thinner, with the fourth abdominal segment more noticeably in- 

 curved at apex, and the subbasal impression of the jDrothorax 

 somewhat closer to the base. 



Tmesi pliorus yoncrae, n.sp. 



i- Of a rather dark reddish-castaneous ; elytra and metas- 

 ternum somewhat paler, palpi somewhat flavous. Clothed with 

 pale pubescence, sparser on head and prothorax, and denser at 

 apex of elytra and under surface of abdomen, than elsewhere ; 

 but under surface of head with a distinct fascicle behind each 

 eye. 



Head with dense distinct punctures ; with two small shallow 

 foveae between eyes, base feebly imj^ressed, the impression very 

 feebly continued to between the antennae, where it suddenly 

 deepens. Antennae fairly stout, extending to middle coxae, first 

 joint distinctly longer than second, second slightly but dis- 

 tinctly shorter than third, and slightly longer than fourth, 

 fourth to eighth short and subequal, ninth and tenth larger 

 and wider, their combined length about equal to that of eleventh, 

 which is ovate. Palpi with the antepenultimate joint setose at 

 apex, the subapical with a thin appendage, and the apical pro- 

 duced at apex and dilated on one side of base. Protltorax 

 slightly longer than wide, strongly convex ; punctures as on 

 head ; with a small round, subbasal fovea, and a larger and 

 somewhat irregular one on each side near base. Elytra not as 

 long as greatest w^idth and shorter than abdomen ; punctures 

 smaller than on prothorax, each with a strong sutural stria, 

 becoming deep at base, another still deeper and larger at base. 

 and strongly impressed to slightly beyond the middle of disc, 

 where it rather abruptly terminates. Abdomen with a narrow 

 carina towards each side of first segment on upper surface. 

 and continued on to basal third of second ; under surface with 

 a large median fovea common to two segments, but deepei- 

 posteriorly. M eta-sternum rather deeply impressed posteriorly. 

 Legs long and thin; front tibiae curved and widened in middle. 

 Length 2i^ mm.
