626 FAUNA HAWAIIENSIS 



(28) Mirostermis molokaiensis, sp. no v. 



Niger (nonnunquam plus minus piceus) nitidus, elytris postice saepe, ad humeros 

 nonnunquam, rubromaculatis, pronoto pallide pubescente. Oculi minores, late separati. 

 Antennarum clava angustior, articulo primo haud aut baud multo, quam secundus, 

 latiore, elongate, margine externo internoque ex magna parte fere parallelis. Elytra 

 glabra, nitida, subtilissime rugulosa, parum (saepe vix evidenter) punctata. Long, 

 vix 2 — 2 '5 mm. 



A most distinct species in spite of the variability in colour. I suspect that the 

 examples with the narrowest and most strongly parallel-sided basal joint of the club of 

 the antennae are males, those in which it is more normal, that is more triangular in 

 shape are females. I have seen only eight or nine examples, most of which have been 

 roughly handled in mounting. The bright red markings are very characteristic, when 

 present. 



Hab. Molokai, on the lowest skirts of the forest. 



(29) Rlirostcrmts kcmaicnsis, sp. nov. 



Niger, nitidus, pronoto plus minusve pubescente, elytris fere glabris, antennarum 

 clava tenuissima et elongata, articulo primo angustissimo, elongato, lateribus fere paral- 

 lelis, secundo circa bis longiore quam latiore, tertio angustissimo et valde elongato. 

 Elytra suturam juxta dense subtiliter punctulata, parte caetera sparsim, minus subtiliter 

 punctata, punctis ex majore parte seriatim dispositis. Oculi latissime separati. Long. 

 2 "2 mm. 



Allied to M. niolokaicnsis but with the antennal characters still more exaggerated, 

 and the elytra differently sculptured. One example, probably a ^, taken. 



Hab. Kauai ; 4000 ft. 



(30) Mirosternus ignottis, sp. nov. 



Niger, parum nitidus, pronoto griseo-pubescente, subtiliter punctulato. Oculi 

 minores, latissime distantes. Antennarum clavae articulus primus parum fortiter dila- 

 tatus, hujus et secundi angulo interno haudquaquam acuto. Elytra juxta suturam, 

 necnon in parte basali circa scutellum subfortiter ruguloso-sculpturata, ibique griseo- 

 pubescentia, parte caetera subtiliter rugulosa, punctis obsoletis perpaucis, vix videndis. 

 Long. 2 '5 mm. 



The single e.xample taken had been very roughly manipulated, being partly broken 

 and very dirty and covered with gum. It has not been possible to study it very satis- 

 factorily, as it could only be handled very carefully in cleaning off the dirt. It appears 

 to most nearly resemble some examples (probably ?) of M. molokaiensis, but the basal
