4o6 FAUNA HAWAIIENSIS 



Fam. DERMESTIDAE. 



Labrocerus Sharp. 



Labrocertis Sharp, Tr. Dublin Soc. in. 1885, p. 148. 



A correction should be made in my original description of the genus. The 

 prosternal process is not "broad and flat," but delicate, narrow and feebly carinate 

 along the middle.

This is a rather variable species in size, and in convexity, as well as in the 

 distinctness of the marks caused by the grey pubescence that exists on the elytra. In 

 the male the basal two joints of the antennae (PI. XIII. fig. 15) are small and black, 

 the third and fourth joints are small and yellowish, the ne.xt si.x joints are, each one, 

 decidedly transverse (the fifth joint though transverse is only slightly so), the terminal 

 joint is as long as the four preceding together, but is not broader than the tenth ; it 

 is very distinctly emarginate on the inner side, near the base, so as to give rise to a 

 slight appearance of curvation. In the female antenna (PI. XIII. fig. i5«), the club 

 is black, the ninth and tenth joints are short, transverse, the eighth is small, and irom 

 this to the very small third joint the colour is yellowish, the first and second joints being 

 quite black. The prothorax is shining, but bears a good deal of pallid hair ; its basal 

 median lobe is large and considerably elevated. There is much granular sculpture at 

 the base of the elytra : the pubescence is well-marked, and some of it is grey, so as 

 to form one or more faint, very irregular, fasciae (a character that varies very much). 

 The legs are blackish, the apical parts of the tarsi strongly infuscate yellow. Thirty 

 specimens.
