with tribulus (as there identified), but really duponti, from 

 which and from all its varieties it is readily distinguished by 

 the highly-polished abdomen and very different prothorax, 

 the rostral sculpture also is different. Regarding the breast 

 as unarmed, it would be associated with horni, with which 

 it has scarcely anything in common. The clothing is irregu- 

 larly distributed, the scales being very dense on the scutellum, 

 elytra, base of head, antennae, and legs ; the setae are dense 

 on the apical slope of elytra, muzzle, antennae, and legs, and 

 sparse elsewhere; the prothorax is fairly densely clothed 

 about the base, but sparsely elsewhere, and such setae as are 

 present do not project upwards, but are almost buried in the 

 derm, in consequence the upper-surface has a softly-polished 

 appearance, strikingly at variance with most species of the 

 genus; the abdomen is highly polished and with but few 

 setae. The inter-ocular fovea appears to be little more than 

 a puncture of moderate size. The median carina of the 

 rostrum appears as a wide obtuse elevation, scarcely separated 

 from the intermediate ones (these being practically absent) ; 

 the sublateral sulci are fairly deep, subcrescentic in shape, 

 and closed at both ends; the scrobes are wide and shallow 

 posteriorly. From above the second joint of funicle appears 

 to be slightly longer than the first, but from the side it is 

 seen to be slightly shorter. Some of the elytral punctures 

 are quite round, but the majority are separated by very 

 irregular zig-zag or vermiculate lines. The carina on the 

 third interstice is continued to beyond the middle, and is 

 then broken up into from two to four small tubercles; on 

 the fifth interstice the carina on two specimens is shorter and 

 posteriorly broken up into feeble tubercles, but on one 

 specimen it is continued as a feeble regular elevation till it 

 vanishes ; on the seventh interstice the carina is short and 

 posteriorly is represented by from ten to twelve small 

 tubercles ; all the tubercles are small, but the most conspicu- 

 ous ones are those on and about the apical slope. 



Leptops insularis, n. sp. 



Black. Densely clothed with pale scales and setae. 



Head with inter-ocular fovea narrow and rather deep, 

 but almost concealed before abrasion. Rostrum not very 

 long; median carina narrow and acutely elevated, the inter- 

 mediate ones rather less acutely elevated ; sublateral sulci 

 rather narrow, somewhat dilated, and open posteriorly. 

 Antennae moderately thin; second joint of funicle somewhat 

 longer than the first, none of the others transverse. Pro- 

 thorax lightly transverse, * sides evenly rounded, surface 

 vermiculate-rugose. Elytra briefly subovate, at widest fully
