4IO FAUNA HAWAIIENSIS 



(13) Lahrocents flavicornis, sp. nov. 



$ Niger, minus convexus, antennis tlavis articulo basali piceo, pedibus fusco- 

 testaceis ; subtiliter punctatus, breviter griseo-pubescens. Long. 2)\ "I"''- 



A single female is all we have to represent what is clearly a distinct species, and 

 probably allied to L. vestitns. It differs markedly by its clear yellow antennae, which 

 are provided with a smaller, less compact, club than usual. The much shorter, and 

 less conspicuous clothing of the upper surface may, in part, be due to attrition. 



Hab. Hawaii, Kilauea, viii. 1896 (no. 656, Perkins). 



Group 4. 



(14) Labroccrus sctosiis, sp. nov. 



% Niger, longius pallido-setosus, elytris fascia post-basali maculisque ante apicem 

 pallidis, antennis articulis 2° ad 6" pallidis. Long. 3! mm. 



Distinguished from the following species by its larger size, black legs, and by the 

 fact that there is much black hair mi.xed with the pale pubescence. Two specimens. 



Hab. Oahu (Perkins). 



(15) Labroccrus pallipcs, sp. nov. 



Niger, convexus, pallido-setosus, antennis pedibusque pallidis, elytris fascia post- 

 basali maculisque ante apicem pallidis. Long. 3 — 3^ mm. 



This species varies in colour, the black being sometimes much reduced, so that 

 the under surface, and even the front of the thorax, may be largely pallid. The 

 antennae of the male are not very thick, so that joints eight — ten are not strongly 

 transverse, the terminal joint is about as long as the four preceding together. Four 

 specimens.

( 1 6) Labroccrus ajfiuis, sp. nov. 



Niger, parum convexus, antennis testaceis clava lusca, tibiis tarsisque fusco- 

 testaceis ; pallido-setosus, elytris fascia post-basali maculisque ante apicem testaceis. 

 Long. 2| — 3^ mm. 



The antennae of the male of this species are rather more slender and a little 

 longer than usual, so that the penultimate and antepenultimate joints are scarcely — • 

 if at all — transverse. This, and the more slender form of the insect, distinguish it from 

 L. pallipes. Eleven specimens.
