have numerous small but distinct tubercles, the rows on the 

 third and fifth terminate near summit of apical slope, the 

 row on the seventh about the middle; in addition, there are 

 numerous small but distinct ones on the suture, and a few 

 still more obtuse ones on the basal third of the second 

 interstice . 



Leptops latipennis, n. sp. 



Black. Densely clothed with small, round, pale, muddy- 

 brown (scarcely fawn-coloured) scales; upper-surface with 

 very inconspicuous setae, but becoming dense and moderately 

 long on abdomen and legs. 



Head with inter-ocular fovea small and partly concealed. 

 Hostrum moderately long; median carina distinct but feebly 

 elevated, the grooves on each side feeble; sublateral sulci 

 rather shallow and open posteriorly; scrobes comparatively 

 narrow, at base directed upwards so as to margin the eyes. 

 Antennae of moderate length; joints of the funicle more 

 cylindrical than usual. Prothorax moderately transverse, 

 sides irregularly rounded, with a rather large median exca- 

 vation; surface roughly vermiculate-tuberculate. Elytra 

 rather briefly ovate, across middle fully twice the width of 

 prothorax; with numerous almost regular rows of rather large 

 punctures : suture, third, fifth, seventh, and ninth interstices 

 tuberculate, tubercles small, but many acutely conical. Legs 

 rather long; tibiae rather strongly denticulate. Length, 

 13-15 mm.

At first glance apparently a member of the group with 

 armed prosternum, but the swellings in front of the front 

 coxae are so extremely feeble that it would be wrong to treat 

 them as armature; the species, therefore, in the 1906 table 

 of the genus would be associated with horni, from which it 

 differs in being considerably larger, rostrum longer and very 

 differently sculptured at sides, and seventh interstice of elytra 

 with a series of small but acute tubercles. In general appear- 

 ance it is somewhat like large specimens of cacozelus, or small 

 ones of parvicorn'ts, but the intermediate carinae of rostrum 

 are not suddenly terminated as on those species. A few of 

 the scales have a golden lustre. The elytral setae are so few 

 in number and so closely resemble the scales that at first they 

 appear to be absent ; even on the apical slope they are incon- 

 spicuous. There is a conspicuous pair of conjoined tubercles 

 on the suture near apical slope, and a few feeble ones before 

 same; on the third and fifth interstices the tubercles are 

 largest (but not very large) posteriorly, on the seventh they 

 are largest towards the base, the tubercles on the ninth are
