COLEOPTERA 485 



conspicuous depression of A^. lambiaiuts ; posterior margin of the last ventral segment 

 feebly bisinuate, the central emargination fringed with short hairs, while the rounded 

 prominence on either side of it bears a tuft of long hairs rising from slightly behind the 

 margin. 



Fourteen specimens. There is a single very small male from the Waianae 

 mountains.

Brachypeplns toi-jiis Blackburn, Tr. Dublin Soc. iii. 1SS5, p. 133. 



This species was described from a single female taken by Mr Blackburn, by beating 

 flowers, on the Waianae mountains. We have now 27 specimens. 



The form is narrow and somewhat elongate, the pubescence conspicuous. The 

 manner of coloration is characteristic. The elytra have a large dark anterior area, and 

 a smaller dark area along the posterior margin. These areas e.xtend the whole width 

 of the elytron, except for the outer lateral margin, which is light usually throughout its 

 length, and which sends a broad light transverse band across the elytron between the 

 dark areas: the light parts are distinctly yellowish, the dark parts almost black. The 

 thorax and abdomen are dark with lighter margins. Thorax rather elongate, not 

 conspicuously broader than long, narrowed in front, with sides explanate towards the 

 hind angles, which are rounded ; disc somewhat convex, closely punctured. Length 

 from 2^ mm. (small female) to 3-5 mm. (large male). 



Male pygidium with a conspicuous notch and a sharp tooth on either side. Supj^le- 

 mentary segment with a median depression or very slight emargination. Female 

 pygidium long, narrow, tapering, with very rounded apex. 



A single male found at Kawailoa (iv. 1901) differs from the rest in having the notch 

 in the pygidium broad and shallow, while the teeth on either side of it are very short 

 and blunt. 



A single female from the Waianae mountains exhibits marked variation. The 

 black colour is greatly reduced; the thorax is uniform reddish-testaceous, and the 

 elytra are testaceous except for two very small areas, one near the scutellum, the other 

 at the posterior margin. The thorax is more conspicuously narrowed towards the front 

 than in other examples.
