beyond the tip; punctures partially concealed. Prosternum 

 unarmed. Front femora longer than rostrum, finely and 

 acutely dentate; hind femora each with a strong acute tooth 

 and a smaller and more obtuse one ; basal joint of front tarsus 

 lightly curved, about half the length of its supporting tibia. 

 Length, 4|-5 mm.

The very long and thin legs and distinctly fimbriated 

 front tarsi are proofs that the three specimens before me are 

 males, although there are no pectoral spines; but two other 

 species (j)ulvereus and serrirostris, both exotic and very differ- 

 ent from the present species) are similarly unarmed. 



The scutellum is conspicuously white, the paler scales on 

 the prothorax form feeble lines fairly distinct to the naked 

 eye but confused under a lens. The white scales, although 

 not clothing the whole of the abdomen, are continuous across 

 the four apical segments. On two specimens the apical half 

 of the hind tibiae is densely clothed with white scales. On 

 one specimen on each elytron the third interstice has three 

 small tubercles about the middle: on another there are two 

 tubercles on each side, and on the other two on one side and 

 three on the other. 



Mecopus ptctus, n. sp. 



Black: antennas, rostrum (wholly or in part), and tarsi 

 reddish; prothorax and elytra sometimes diluted with red. 

 Rather densely clothed with scales varying from white (usually 

 tinged with ochreous) to slaty-brown. 



Rostrum not twice as long as eyes : apical third shining 

 and with fine but distinct punctures, basal two-thirds with 

 coarser but partially-concealed punctures, and with an acute 

 median carina and several feeble sublateral ones. Second 

 joint of funicle distinctly longer than first. Prothorax almost 

 thrice as wide as the length down middle; punctures normally 

 concealed. Elytra subtriangular ; with series of large, suboblong, 

 partially-concealed punctures ; without small conical tubercles, 

 but with fairly numerous granules, which on the third inter- 

 stice form a feebly-elevated ridge about the base and middle. 

 Prosternum unarmed. Front femora about as long as ros- 

 trum, each with an acute and rather small tooth, middle 

 rather more strongly armed, hind pair each with a large tri- 

 angular acute tooth ; tarsi about as long as tibiae, basal joint 

 of each about half its total length. Length, 3J-5 mm.
