640 FAUNA HAWAIIENSIS 



(64) Mirostcrnus debiiis Sharp. 



Mirosternus debiiis Sharp, Tr. Ent. Soc. London, 1881, p. 525. 



To this species I refer four examples taken on Oahu, and I believe it to be very 

 variable in colour. Some of these specimens are black with a red spot on each wing 

 case towards the apex, or there may be in addition to these a basal red spot on each, or 

 the whole insect may be reddish, a darker area traversing the elytra behind the base. 

 The puncturation varies in intensity. The eyes are small and very remote. 



Hab. Oahu, Waianae mountains. 



(65) Alirostcrnus varius, sp. nov. 



Niger, elytris ad basim singulis saepe rufo-notatis, versus apices etiam saepe rufo- 

 maculatis, sat nitidus. Oculi minores, latissime separati. Antennarum clava haud- 

 quaquam magna, articuli i et 2 angulo interno haud acuto. Pronotum nitidum, pallide 

 pubescens, sed vix distincte punctatum. Elytra subaequaliter pallida pubescentia 

 vestita, subtiliter sat aequaliter sed plus minus indistincte aut obsolete punctata. 

 Long. 3"2 5 mm. 



Except when more or less brightly marked with four red spots on the elytra (some 

 or all of these spots may be absent), this is an obscure species. It is chiefly distinguished 

 by the small eyes, moderate or small antennae (sometimes even the club being pallid) 

 and the close but indefinite or subrugulose puncturation of the elytra, which is very 

 shallow. Ths clothing of these is evenly distributed. 



Hab. Kauai, 4000 ft. 



(66) Rlirosternus hirsutnlus, sp. nov. 



Brunneus, elytris nigro-marginatis, pubescentia pallida flavescente dense vestitis. 

 Oculi minores, late separati. Antennarum clava angustula, elongata, articulo primo 

 elongato, minus fortiter dilatato, angulo interno haud acuto. Pronotum subtiliter 

 punctatum, sat dense pubescens. Elytra subtiliter, sat crebre subaequaliter punctata, 

 lateribus nitidis, fere glabris, rugulosis et parce punctatis, punctis majoribus, leviter 

 impressis. Long. 2*5 — 3 mm. 



I have examined two specimens, which agree in nearly all respects, except that one 

 is much larger than the other. The pubescence is rather coarse and shaggy. This 

 character, together with the colour and the elongate narrow basal joint of the club of 

 the antennae, the puncturation, and glabrous sides of the elytra will distinguish the 

 species. 



I have also a specimen, given me by Koebele, from Oahu, but without special 

 locality, which differs in the colour of the elytra, the side margins not being black, and
