84 Mr. D. Sharp on some 



angles are extremely rounded ; tlie sculpture consists of 

 series of somewhat indistinct punctures, with a scanty 

 and extremely fine punctuation on the interstices. The 

 punctuation of the exposed dorsal segments is rather close 

 and distinct. 



Three specimens have been found in flowers in the 

 mountain forests of Oahu ; the one sent me by Mr. 

 Blackburn was numbered 191. 



This specimen is no doubt a male ; the last dorsal plate 

 is emarginate and the last ventral truncate. There is a 

 distinct but short, exposed supplementary segment. 



In company with these three individuals Mr. Black- 

 burn found two others, which he considers to be the 

 female. One of these he has sent as No. 190; it has 

 the head narrower, and the head and thorax much less 

 closely punctured. The elytra are rather shorter, and 

 leave exposed a greater portion of the hind body, and the 

 exposed dorsal segments are much less punctured. The 

 apex of the last dorsal segment is depressed in the middle, 

 but not emarginate, and there is no supplementary segment 

 visible. Mr. Blackburn is probably right in considering 

 this to be the female of the male above described ; still the 

 distinctions are of such a nature that I have not thought it 

 right to treat the tAvo forms as positively the sexes of one 

 species at present. 



B. tinctus is interesting as making a considerable 

 approach to Gonioryctus, from which, however, it still 

 remains distinct by the finely-facetted eyes, and the much 

 less elongated lobes of the third tarsal joint. It should be 

 placed at the head of the Hawaiian Bracliyjoepli, before 

 B. discedens.
