6^,2 FAUNA HAWAIIENSIS 



M 



(43) Mirostermis cognatiis, sp. nov. 



Nicrricans, nitidus, capite pronotoque et parte apicali elytrorum plerumque plus 

 minusve rufescente. M. konano similis et affinis, sed antennarum ^ clavae articulis 

 minus dilatatis, oculisque minoribus distinguendus. Metasternum anterius haud cari- 

 natum. Long. 3 "5 mm. 



I have examined about a dozen examples of M. cognatus and find only small 

 differences between the joints of the antennal club in any of these, although it is 

 hardly possible that both sexes are not represented. The antennae, in fact, are 

 very like those of the female of M. konanus. If, therefore, I understand the species 

 rightly, and both sexes of M. cognatits are present, the males having a slightly 

 more developed antennal club, then this species is entirely distinct from M. konanus 

 by the only slight, sexual dimorphism, and the much smaller eyes and antennal club 

 of the $.

(44) Mirostermis aniatns, sp. nov. 



Rufobrunneus, pronoto sat dense flavo-pubescente. Oculi magni, prominentes, 

 sed sat distantes, unus ex his spatio frontis intermedio vix latitudine aequalis. Anten- 

 narum clava sat mao-na, an^ulis internis sat rotundatis, haud acutis, articuli secundi 

 apice parum producto. Elytra parce pubescentia, nitida, minus subtiliter punctata, 

 apicibus opacis, densissime minute punctatis, densius flavo-pubescentibus, parte basali 

 extrema (nisi juxta humeros) haud dense punctata. Long. 275 mm. 



Closely allied to M. konanus &c. The punctures on the more glabrous parts of 

 the elytra are less fine than usual, and seem uneven in size. Even along the suture the 

 puncturation is not very dense and fine except posteriorly. Along the basal margin the 

 punctures are by no means dense except perhaps close to the humeral prominence. 



1 have seen but one specimen, which having been bred is in very fine condition ; 

 and probably more clothed with hairs on the smooth parts ot the elytra than a caught 

 specimen would be. Its antennae are pale in colour, but this is not likely to be a 

 constant character. The tree from which it was bred was entirely dead, but I think it 

 was a Chcirodendi'on. 



Hab. Oahu, Honolulu range, 1500 ft. 



(45) Mirostei^nus parens, sp. nov. 



Castaneus aut castaneo-niger, sat nitidus, pronoto sat dense pubescentia pallida, 

 saepe flavescente, vestito, subtilissime (anterius perparce) punctato. Oculi $ majores 

 sed sat distantes, feminae, quam maris, multo minores et latissime distantes. Anten- 

 narum clava $ magna, articuli primi apice fortiter producto, angulo interno haud acuto ;
