COLEOPTERA 629 



(35) Mirosfcruus nigrocastaiieiis, sp. now 



NioTocastaneus, minus nitidus, antennarum basi rutescenttj, clava niy;ricante. Oculi 

 magni, singulis ac spatium frontis intermedium fere aeque latis. Pronotum pallide 

 pubescens, nitidum, parum distincte punctatum. Elytra ad suturam dense punctata, 

 ibique pallide pubescentia. parte caetera subtiliter rugulosa, sparsim subobsolete minus 

 subtiliter punctata, sparsim et parum conspicue pubescentia, sutura versus apicem baud 

 impressa. Metasternum ?_, anterius tortiter carinatum. Long, vix 3 mm. 



I have seen but one example, no doubt a male; the antennae are strongly developed, 

 but of usual form, the two basal club-joints triangular, somewhat strongly dilated, with 

 the inner angle blunt.

(36) Mirosteriiits xaiithostictus, sp. nov. 



Nigricans aut plus minusve piceus, antennarum articulis basalibus pedibusque 

 rufescentibus, capite pronotoque pallide pubescentibus, hoc subtilissime minus distincte 

 punctulato. Oculi sat magni sed late distantes. Antennarum articuli 3 ultimi sat 

 magni, horum primo haud acute intus angulato, apice fortius producto. Elytra fla- 

 vescentia, plaga magna subtriangulari basali, fascia transversa postmediana, sutura, 

 marginibusque lateralibus, nigricantibus, fere glabra, parcissime obsoletim punctata. 

 Long. 2*5 mm. 



The two examples described are probably males and the species is unlike any 

 other. A third e.xample taken subsequently and I think in another locality is a marked 

 and perhaps constant variety, the posterior yellow colour of the elytra is reduced to two 

 small spots, the punctures are more evidently serially arranged in shallow grooves and 

 are more distinct, while the antennae are also slightly different. 



Hab. Oahu, Waianae mountains; the variety probably in the Honolulu range.

Miros^tcnuis bicolor Sharp, Tr. Ent. Soc. London, 1S81, p. 525. 



I have seen one example of this insect, taken either by Koebele or myself, when 

 collecting together. Previously I had supposed that the specimens of M. xaiithostictiis 

 would prove to be i\I. bicolor, since they came from the same localit)' as the t)"pe ot the 

 latter species. The two are, however, quite distinct. The eyes of M. bicolor are of 

 moderate size and are widely separated. 



Hab. Oahu, Waianae mountains (Blackburn); Honolulu mountains.
