-ivith a fine black pxibcscence ; 6th finely punctured, 7th 

 more sparingly and finely punctured, these two with a 

 concolorous yellow pubescence. 



Legs black, with the tarsi obscure reddish. 



In the male the 6th segment on the underside is fur- 

 nished in the middle with a line of yeiy long projecting 

 hairs, and the hind margin is slightly emarginate ; the 7th 

 segment has a large triangular notch ; the {^deagus is 

 large, and is furnished with a stout ligula projecting far 

 beyond the body of the organ and bifid at the extremity. 

 In the larger indiyiduals of this sex the mandibles and 

 palpi are more elongate, and the elytra are furnished near 

 the outside Ayith a longitudinal fold or plica of yariable 

 length ; this is quite absent in the smaller males. The 

 anterior tarsi are quite simple. 



Ega ; nine specimens. 



2. Plociopterus fungi, n. sp. Niger, nitidus, abdo- 

 minis apice rufo-testaceo ; elytris cyaneis, fasciatim cinereo- 

 pubescentibus ; antennis articulis duobus ultimis albidis.

This species is almost the same as P. tricolor in most 

 respects, but it has only two joints at the apex of the 

 antennas white, and the male characters are a little diffe- 

 rent. 



In the male the 6th segment is on the underside, 

 furnished across the middle with a curyed line of long 

 projecting hairs, and its hind margin is rather deejjly 

 emarginate; the 7tli segment bears a large triangular 

 notch. The ledeagus is similarly formed to that of 

 P. tricolor, but its elongate ligula is less produced, and 

 the bifid processes at its extremity are shorter and more 

 rounded. 



Paru; a single specimen found by Mr. Bates; it is 

 labelled " stump fungus." 



Obs. — As I have dissected out the ajdeagus in three 

 males af P. tricolor, and find its form to be completely 

 similar in the three, I cannot consider this individual to 

 be a mere variety of the Ega species.
