(38) Afiros/erims glabripcnnis Sharp. 



Miroste7-nus glabripennis Sharp, Tr. Ent. Soc. London, 1881, p. 524. 



This species greatly resembles M. juontanns and allied species in sculpture but is 

 easily distinguished by the much larger eyes, the width of one of these being not much 

 less than the space, where least, between them. There is a slight tendency in the 

 elytra to become uneven from longitudinal grooves or depressions and of the very 

 sparse subobsolete punctures to be serially arranged. Whether the types, which are 

 supposed to be ^ and $, are really so, and not slightly differently developed examples 

 of one sex is I think doubtful. 



Since the above was written I have myself taken an example of M. glabripennis, 

 which before was wanting in my collection, in the Honolulu range of mountains, and 

 still more recently another yet nearer to Honolulu itself. I have never found it in 

 the Waianae mountains nor is it likely to exist there now at so low an elevation 

 (1000 ft.) as that at which it was found by Blackburn. The antennae are sometimes 

 rufescent. 



Hab. Oahu, Waianae mountains (1000 ft.) Blackburn; near Waialua and near 

 Honolulu, 1 200 — 1 500 ft. 



(39) Mirostcrmis pallidicornis, sp. nov. 



Nigrocastaneus, nitidus, capite, pronoto elytrorumque apicibus plus minus rufes- 

 centibus, antennarum clava lucide testacea. Oculi majores sed late separati. Anten- 

 narum clava ($ et Z ?) mediocriter magna, articulo primo triangulari, angulo interne 

 haud acuto. Pronotum parum nitidum, pubescens, subtilissime punctatum. Elytra 

 elongata, nitida, ex majore parte fere glabra, tantum juxta suturam (praecipue apicem 

 versus) dense et minutissime punctulata, ibique aureo-pubescentia, parte glabra spar- 

 sissime minus subtiliter punctata. Long. 3*75 mm. 



Very closely allied to M. glabripennis Sh., but distinguished by the more elongate 

 elytra, which become very gradually narrower from base to apex. Having seen but 

 one example, I do not know whether the colour of the antennae is constant. The same 

 pallid colour is known to appear as a variation in several other species and probably 

 occurs in most. 



Hab. Kauai, 4000 ft. 



(40) Mirosfernus peks, sp. nov. 



Nitidus, niger, pronoto pallide pubescente. Elytra elongata, fere glabra, niti- 

 dissima, sparsissime punctata, circum suturam (saltem posterius) minutissime punctata, 

 pallideque pubescentia, parte apicali latera versus obsolete ruguloso-sculpturata. Oculi
