tween four anterior coxae. Mesostemal receptacle raised, sides 

 incurved to base, emargination semicircular ; cavernous. 

 Metastemum much shorter than the following segment; epis- 

 terna very narrow. Abdomen moderately large, sutures (ex- 

 cept between first and second segments in middle) deep and 

 distinct ; first as long as second and third combined ; third and 

 fourth combined slightly longer than second or fifth. Legs 

 moderately long; femora comparatively thin, feebly grooved, 

 edentate, posterior terminating before apex of abdomen ; tibiae 

 compressed and feebly bisinuate beneath, in addition to the 

 terminal hook with a very feeble subapical tooth; tarsi 

 moderately thin, not shining, third joint moderately wide and 

 deeply bilobed, fourth elongate. Elliptic, convex, squamose, 

 fasciculate, apterous. 



Very close to Roptoperus, but the scape inserted nearer 

 apex than base of rostrum and the length of funicle, the abdo- 

 men convex, the femora thinner and grooved, the tarsi (though 

 rather thin) not shining, and with the third joint rather wide 

 and deeply bilobed. 



Cairnsicis opalescens, n. sp. 



Black, antennae and claw joints of a rather pale-red. Very 

 densely clothed (except on under-surface) with fawn-coloured 

 scales, denser on prothorax than on elytra; on the former they 

 are large, circular, and condensed into numerous small 

 fascicles, on the latter they are smaller and less rounded and 

 the scales of the (rather numerous) fascicles are shining. Head 

 (except at base) and base of rostrum moderately-densely 

 clothed. 



Head feebly convex ; base impunctate and shining ; near 

 base a circular line formed by dense, small, and confluent punc- 

 tures, before this line shining, elsewhere with coarse, concealed 

 punctures. Rostrum the length of prothorax, almost parallel- 

 sided throughout ; basal third with coarse, concealed punctures, 

 elsewhere polished and lightly punctate. Scape inserted at 

 apical third; two basal joints of funicle equal in length, the 

 others transverse. Prothorax slightly transverse; punctures 

 concealed ; subtuberculate beneath fascicles, with a very feeble 

 shining median carina. Elytra slightly wider than prothorax 

 and about once and one-half as long ; shoulders emarginate to 

 receive posterior angles of prothorax; with series of large, 

 round, partially-concealed punctures; subtuberculate beneath 

 fascicles; a small, shining, conical granule on each side of 

 scutellar region. Under-surface, except third and fourth abdo- 

 minal segments, with moderately large and dense but partially- 

 concealed punctures. Posterior femora extending almost to
