FA UNA HA IVAIIENSIS 



(69) Mirosternus obsairus Sharp. 

 Mirosternns obsairus Sharp, Tr. Ent. Soc. London, 1881, p. 523. 



I refer to this species a series of specimens obtained on four of the islands. It varies 

 in colour from brown to pitchy or almost black. The club joints of the antennae are 

 usually pale, or at least not black, and compared with most species of the genus the club 

 joints are unusually ill-developed. The eyes are small and very widely separated. 

 The dense puncturation is continued right to the lateral margins of the elytra, and 

 extends along these the whole way to the base. Very fresh examples from Oahu have 

 the pubescence of the elytra more irregularly disposed than those from Hawaii, but 

 otherwise seem to be identical. 



Hab. Oahu, Molokai, Maui, Hawaii. — Widely distributed on Hawaii. 



(70) Rlirostcrmis solidus, sp. nov. 



Major, fusco-niger, antennis testaceis. Oculi mediocriter magni, latissime distantes. 

 Antennarum clava parum magna, articulo primo elongato, parum fortiter dilatato, angulo 

 interno baud acuto. Pronotum crebre et distincte ubique punctatum, dense pallido- 

 pubescens. Elytra distincte crebre punctata, apices versus densissime minutissime 

 punctulata, ubique flavido-pubescentia, lateribus usque ad humeros dense punctatis. 

 Metasternum baud carinatum ; abdominis segmentum ultimum ventrale ad apicem sat 

 distincte impressum. Long. 375 mm. 



I have seen only one example of uncertain sex. The pubescence is of a rather 

 obscure yellowish colour. The species is allied to M. obscitrns Sharp. 



Hab. Kauai, 4000 ft. 



Earn. BOSTRYCHIDAE'. 



All the Bostrychidae found in the islands have, no doubt, been introduced by man. 

 Some of them are now extremely common and Schistoceros cortiuitis, Apate lifuana and 

 Sinoxylon conigeruni may be considered as injurious insects, and perhaps some of the 

 others should be placed with these.

Hab. Hawaiian Islands, abundant. I have taken the same species in Mexico. 

 Hawaiian specimens vary greatly in size. Widely distributed in America and the 

 Antilles.
