noticeably decreasing in width to base, and with distinct im- 

 pressions. The type is almost certainly a male. Its rostrum 

 is rather wider and more strongly curved, and the antennae 

 stouter, than usual. On the upper-surface the sooty scales 

 are perhaps in the majority, but owing to their colour they 

 are but little conspicuous. On the under-surface the scales are 

 dense and almost setose in character, on a space occupied by 

 the four front coxae and the intercoxal parts of the meso- and 

 metasternum. The prothorax is not carinated along middle, 

 but from some directions a feeble median line can be traced. 

 The punctures on the basal two-thirds of elytra are usually 

 truncated at the base and rounded at the apex, so that they 

 have a subconical appearance ; towards the sides, however, 

 they are more rounded. The front femora each have a 

 moderately distinct tooth in the usual position, but in addi- 

 tion, between this one and the base, there is a swelling in the 

 form of a very obtuse tooth. 



Omydaus longus, n. sp. 



Black; antennae and claw joints obscurely reddish. 



Head coarsely punctured. Rostrum stout, moderately 

 long, strongly curved, somewhat gibbous near base; with 

 coarse punctures throughout. Antennae rather stout; scape 

 inserted two-fifths from apex of rostrum, distinctly shorter 

 than funicle; first joint of funicle slightly longer than second. 

 Prothorax flat, distinctly longer than wide, base strongly 

 bisinuate, hind angles overhanging base of elytra, sides feebly 

 increasing in width from base to near apex, which is suddenly 

 and strongly narrowed; surface uneven and with coarse 

 irregular punctures; with a narrow median carina. Elytra 

 narrow, very little wider than prothorax, sides irregularly 

 parallel, base strongly trisinuate, apex widely rounded, with 

 large irregular punctures and irregular interstices. Under- 

 surface with more or less concealed punctures. Basal segment 

 of abdomen widely depressed, second very little longer than 

 third. Femora stout, hind pair not extending to apex of 

 abdomen. Length, 9 mm.

A narrow roughly-sculptured species with coarse punc- 

 tures on rostrum even to the apex; it also slightly decreases 

 in width from the antennas to base, a most unusual character 

 in the subfamily. On the elytra the punctures are concealed, 

 except on the sides, where they are large and round, but on 

 abrasion the others are seen to be very large, suboblong, and 

 in irregular double series, with the alternate interstices irregu- 

 larly elevated or subtuberculate. The femora are neither
