*Trogocryptus longiusculus, n. sp. 
Moderately elongate, rather broad, subparallel, very shining, 
glabrous; ferruginous, the apical half of the elytra, the disc of the 
thorax, and part of the under surface sometimes piceous or black. 
Head very broad in fully-developed 3, narrower in 9, finely and 
somewhat thickly punctate, transversely grooved or bifoveate behind 
the epistoma; antennae short, joints 4-8 strongly transverse, the 
club very abrupt, joint 10 wider than 9. Thorax transverse, 
moderately convex, rounded at the sides, and a little narrowed 
towards the apex in 9, broader anteriorly in 3, finely margined, the 
angles obtuse; finely, somewhat closely punctate. Elytra com- 
paratively short, finely punctate-striate, the interstices minutely 
uniseriate-punctate. Beneath with a few scattered fine punctures 
along the sides, for the rest almost smooth. Legs short; tibiae 
rapidly widened outwards, acutely dilated at the outer apical angle, 
and spinulose along their apical margin. 
Length 31-33 mm. (¢ 9.)

Eleven specimens, some of them uniformly ferruginous, 
others with the dise of the thorax and the apical half of 
the elytra infuscate, those with broader head and thorax 
assumed to be males. This species is considerably less 
elongate than 7’. mgripectus, Sharp, and also differs from it 
in the transverse thorax and the finely punctate-striate 
elytra. 
*Trogocryptus senecionis, n. sp. 
Elongate, subcylindrical, moderately convex, shining, glabrous; 
black, the head, antennae, and legs, and in one specimen the sides 
of the thorax, the humeri, and the under surface also in great part, 
ferruginous. Head alutaceous and finely punctate, transversely 
grooved behind the epistoma, the eyes not prominent; antennae 
reaching very little beyond the middle of the thorax, joints 4-8 
transverse, the club abrupt, rather large, joints 9 and 10 equal in 
width. Thorax convex, transverse, rounded at the sides, about 
equal in width at the base and apex, the sides sinuate before the 
rectangular hind angles, the base distinctly margined; thickly 
punctate, the punctures oblong in shape, the interspaces finely 
alutaceous. Elytra elongate, scarcely wider than the thorax, 
parallel to beyond the middle; punctate-striate, the interstices
