284 FAUNA HAWAIIENSIS 



sixth consisting only of three or four rather indistinct punctures ; the pair of impressions 

 on the third interstice small. Five specimens. 



Similar in size and shape to Nesocidiiivi koebelci, but readily distinguished by the 

 colour and the smaller eyes. 



Hab. Kauai. Mountains, Waimea, 4000 ft., June 1894; Koholuamano, April 

 1895 (Perkins). 



(9) A^csocidhnu atoniaritun, sp. nov. 



Nigrum, antennarum articulo basali pedibusque sordide rufis ; prothorace vi.x 

 transverso ; elytris ovatis, conve.xis, seriatim parce punctatis, parte apicali impunctata. 

 Long. 2^ mm. 



Distinguished from N. corticai-iiim by the shorter form, the black colour, and the 

 convex elytra. The antennae are obscure red, with the basal joint red. Thorax not 

 much more than half as broad as the elytra, much narrowed behind, canaliculate on the 

 middle ; the systematic setae long. Elytra very convex, greatly rounded, with similar 

 abbreviated series of punctures, but even more reduced. 



Hab. Oahu. Mountains near Honolulu (Koebele). On Pipfurns, back of 

 Tantalus, August 1900 (Perkins). 



(10) Nesocidiiim scydmaenoidcs, sp. nov. 



Minutum, haud latum, rufulum, nitidum ; prothorace vix transverso ; elytris seriebus 

 paucis et valde abbreviatis punctorum. Long. 2-J mm. 



Smaller than M. atoniarium, narrower, dark red, unicolorous, and distinguishable 

 from all its congeners by the narrow head with small eyes. The thorax is narrow, very 

 shining, extremely finely canaliculate along the middle, moderately narrowed behind, 

 enlarged just sufficiently at the hind angle to bear the seta. Elytra narrowly oval, 

 convex, with a sutural stria extending to the tip and outside this with three other series, 

 extremely abbreviated so that the outer consists only of about seven or eight rather 

 obscure punctures. One male specimen. 



Hah. Oahu. Ridge north of Nuuanu Valley, 2000 ft., October 25, 1S92 

 (Perkins). 



Atelidium, oren. nov. 



Corpus apterum, breve, convexum. Caput brevissimum. Thorax utrinque seta 

 unica ad angulum basalem sita. Oculi mediocres. 



This extraordinary little Bembidiid is much more obese than any of the species of 

 Nesocidium, and is readily distinguished by the absence of the anterior of the two 

 thoracic setae. The striation of the elytra extends considerably nearer to the tip than 

 it does in Nesocidium.
