defined suture as in L. atricillus, distinctly alutaceous, with bold and regular 

 piinctvires, which are more remote tlian in the allied species and are to some 

 extent, especially at base and near suture, seriate. Legs : testaceous, with 

 last joint of all tarsi black ; posterior femora black above, testaceous beneath ; 

 first joint of anterior tarsi in S distinctly dilated ; posterior tibial spurs short . 

 Underside black. Winged. Length 15 — 2 mm. 



This is a species wliicli appears to be rare in Britain, and about 

 which much confusion prevails. It is often represented in British 

 collections by either L. atricillus or L. sntnreUvs. From the former, 

 the quite black thorax, the marked difference in strength of punctua- 

 tion of the thorax and elytra, and the more regular, remote, and 

 subseriate character of the ptmctuation of the elytra, together with 

 the presence of wings, will distinguish it. L. snturalis perhaps more 

 closely resembles L. suturellus, but from this species its more parallel 

 shape, the distinct, if weak, thoracic, and the much stronger elytral 

 punctuation, will separate it.

PSEUDOCHALCOTHEA SHELFORDI, n. Sp. 



P. auripedi ■nmilis. Capite pedihusque viridis, antennis viridi-piceis. 

 J. Tihiis posticis pone medium di/atatia, intus ad basin loho longo, tibire 

 longiore, sat lata, curvuto, apice abrupte recurvato, acuta. ? . Tihiis antiris 

 lateribus nigra piceis. Long.. 35 — 37 vim. 



Very similar to P. auripes, Westw., but a little larger, the legs entirely 

 green, and the antennae piceous, tinged with green. The male differs in having 

 the appendage of the hind tibia? free almost from the base, mvich longer, 

 broader, and more abruptly bent near its apex, and the tibia itself dilated below 

 the middle. In the female the outer side of the front tibiae, including the teeth, 

 is black. In P. virens, Bits., to which it is also closely allied, the appendage of 

 the hind tibiae, in the male, arises from the middle .and is of a diiferent form, 

 and the female has the sixth abdominal segment broadly emarginate and more 

 prominent at the sides.

Both sexes received from Mr. R. Shelf ord, and also in the Sarawak 

 Museum.
