hundreds. In the great islands of the Indo-Malayan 

 region, on the contrary, I never saw a specimen of the 

 genus, and this fact will illustrate its peculiar distribu- 

 tion, as well as the localities of the several species. 



1. LOMAPTERA STRIATA, n. S. (PI. XI. fig. 8) . 



Viridis, lata, sub-convexa ; pygidio conoideo, transverse, 

 compresso, vix carinato ; thorace punctato ; elytris 

 punctato-striatis ; tarsis viridi-cupreis. 



Broad, slightly convex ; head deeply punctate, thorax 

 finely punctate throughout, more deeply at the sides, 

 lobe rather short, entire ; scutellum visible, elongate, 

 triangular ; elytra distinctly punctate-striate, with a few 

 scattered punctures, gradually rounded at the sides, 

 where the punctures merge into coarse transverse strise, 

 apex rather deeply notched ; pygidium broad and short, 

 terminating in an obtuse transverse keel, not projecting 

 beyond the apex of the elytra. Anterior tibias with two 

 strong lateral teeth in the female, in the male much smal- 

 ler, the second almost obsolete ; posterior tibiee stout, 

 with a notch on the outside about one-third from their 

 apex ; sternum with the sides punctured, the sternal 

 process much curved, stout at the base, and ending in a 

 rather acute point, in some specimens with a boss or 

 tubercle between the middle pair of legs. Colour entirely 

 green or bronzy-green, the tarsi more bronzy^ the club 

 of the antennae bronzy-black, and the sternal spine 

 bronzy. 



Length 15-17 lines.

 ?.) (B. M. c?.) 



A fine species, but difiering much from the usual type 

 of Lomaptera by the sub-convex striated elytra which 

 entirely cover the abdomen. It must be considered the 

 most aberrant form of the genus. 



2. Lomaptera timoriensis, n. s. 



Nigra, polita ; thoracis disco tenuiter punctato ; elytris 

 lateribus distincte, disco obsolete punctato-striatis; 

 pygidio conoideo, obtuse. 



Head punctate; thorax smooth, polished, very finely
