British New Guinea, Upper Aroa River {A. S. Meek) ; 

 Babooni [A. E. Pratt). 



Very like L. Annce, Hell., but smaller and of a narrower 

 form, the colour and markings similar, but with a very distinct 

 opalescent iridescence on the thorax and elj'tra ; the head is 

 very much more sparsely and finely punctured, especially 

 towards the apex of the clypeus ; the thorax is also less 

 punctured and narrower at the base (the angles being less 

 divergent) ; the elytra are a little emarginate at the apex, 

 with the sutural angle slightly produced ; the pygidium of 

 the male is similar to that of An nee, but in the female it is 

 less produced than in that species, much broader and almost 

 truncate at the apex ; it is also more coarsely aciculated on 

 the upperside and more deeply impressed on each side beneath. 

 The male forceps of the two species are also very diiferent. 



The extent of the black markings varies considerably in 

 the series before me ; the margin of the clypeus and the 

 basal portions of the sides of the thorax and elytra are 

 generally narrowly edged with black, and in some specimens 

 tills narrow black edging also extends to the apical and basal 

 margins of the thorax and the basal and sutural margins of 

 the elytra ; there is often a more or less distinct black spot 

 on each side of the thorax and on the shoulders, and some- 

 times two small linear marks on the forehead ; in several 

 specimens there are rows of dark punctiform spots on the 

 elytra. On the underside the black coloration frequently 

 extends to the prosternum, coxee, abdomen, and other parts, 

 whilst the tibipe in some are almost entirely black and in 

 others only partially so. 



Mr. Pratt obtained a rather large series of both this 

 species and Aiiha', the latter also showing considerable varia- 

 tion in the extent of the black markings.

 this species named var. pseudorufa by Dr. Heller, there are
