666 FAUNA HAWAIIENSIS 



(14) Proterhinus miniimis, sp. nov. 



Rufescens, elytris utrinque saepius nigro- vel fusco-notatis, antennis apices versus 

 nigricantibus, elytris satis erectis gracilibus parce vestitis. Antennae crassiusculae, 

 clava 3-articulata. Pronotum antice impressum, lateribus plaga densiore squamosa 

 ornatis. Elytra parce squamosa, angulis humeralibus distinctis, sed baud acute pro- 

 ductis. Long. r5 — 2 mm. 



One of the smallest species of the genus, best recognized by the red colour, small 

 eyes and tarsal lobes, the sparse and rather fine erect setae of the elytra, the dense patch 

 of squamosity on either side of the pronotum, and the form of the antennae. The 

 scape in the male is large for the size of the insect and the funicle joints are thicker 

 than usual, giving the antennae a rather stout appearance. Two abraded specimens 

 with entirely red antennae may also belong to this species.
