620 FAUNA HAWAII EN SIS 



( 1 1 ) Mirostermis duplex, sp. nov. 



Niger, fusco-niger aut piceus, flavido-pubescens. Oculi maris permagni. Anten- 

 narum clava magna, articuli i et 2 angulis interioribus subacutis. Elytra dense 

 subrugulose fortius, apices versus minutissime, punctata, lateribus rugulose punctatis. 

 Long. 3 mm. 



The above diagnosis applies only to the male, which is fairly easily distinguished 

 by the characters given. Except near the shoulders the sculpture on the sides ot the 

 elytra is close and rugulose to, or very near to, the lateral margin. The eyes are very 

 large, the club joints of the antennae in certain aspects have an appearance of being 

 slightly produced at their inner angles, making them acute. 



The female is entirely different in many ways, the eyes are small and very remote, 

 the antennae are much smaller, but the club joints appear to be similarly formed, though 

 the characteristic appearance, owing to their small size, is less noticeable ; the elytra, 

 except on the apical portion, are much more sparsely punctate, while at the sides they 

 are smooth, except for some very fine longitudinal sulci, and very sparse punctures. 



Hab. Hawaii, occurs at Kilauea and the sexes have been taken in cop. 



(12) Mirostermis euceras, sp. nov. 



Major, oblongLis, castaneus, antennis nonnunquam nigricantibus, sat dense fiavido- 

 pubescens. Oculi permagni, spatio frontis intermedio fere bis latiores. Antennarum 

 clava permagna, angulis interioribus baud acutis. Pronotum dense, minutissime 

 punctulatum. Elytra ex majore parte dense distincte punctata, lateribus fere ad apices 

 glabrioribus, parce punctatis. Long. 3'5 mm. 



Distinct by its colour, robustness, sculpture, huge eyes, etc. The elytral punctura- 

 tion is less dense from a little way behind the base, and becomes excessively dense and 

 minute on the apical portion. 



Hab. Molokai, 3000 ft. 



(13) Mirosteriius lanaiensis, sp. nov. 



Praecedenti cognatissimus, sed colore magis nigricante, elytris apices versus plus 

 minus pallidioribus. Elytra parte apicali e.xcepta distincte, minus dense punctata. 

 Long. 3-5 mm. 



The elytra are closely punctate along the basal margin as in M. euceras, and also 

 are more sparingly punctured behind this, while on the apical portion both species have 

 similar dense puncturation, except that in the present species these dense punctures 

 extend to the lateral margins for a considerable distance towards the base. The eyes
