COLEOPTERA 479 



(9) Nesopeplns roridns, sp. nov. 



Dense punctatus, evidenter pubescens, haud nitidus, niger, antennarum basi 

 prothoracisque marginibus flavis, elytris flavo-variegatis, pedibus testaceis, plus minusve 

 tuscescentibus ; elytris minus obsolete sculpturatis. Long. 3 — 4, lat. i^ — i^ mm. 



This is really very closely allied to M. vagepictiis, though looking different on 

 account of the dark colour. The antennae are yellow, with the club black. The upper 

 surface has a more or less slightly metallic tinge, and the sides of the thora.x are narrowly 

 yellow ; except for this the insect looks blackish though there are obscure yellowish 

 marks on the elytra. The thorax in the male is extremely densely punctured and 

 quite dull, in the female the punctuation is not quite so dense. The elytra have a 

 rough appearance, the striae being slight but sufficient to interfere with the regularity 

 of the surface, and the punctures are not very minute. The legs are sometimes nearly 

 clear yellow and at others blackish. It is difficult to distinguish the male and the 

 female by the pygidial structure, the male pygidium not being emarginate, but the male 

 is often very different from the female by the larger size, broader thorax, and the 

 very dense punctuation of it and the head ; the female has the legs thinner than the 

 male. 



The above description is taken from Kauai examples which are the most distinct. 

 The small series from Maui does not differ much from the Kauai examples. From 

 Lanai there are two examples, one of them very immature, the other in bad preser- 

 vation ; they appear to come nearer than the others to N. vagcpicius. 



The series from Oahu consists of 24 examples, 18 from Waianae of small size, 

 six from the Kaala mountains and other localities. In these specimens the colour is 

 variable, but the dark pigmentation is less than in the Kauai exponents. There are 

 also three specimens, from the Waianae mountains, which are of the largest size of 

 the species, and are specially deficient in dark coloration, but I can find no definite 

 evidence of anything more than variation.
