118 Mr. D. Sharp's Contributions to the 



■uitli a fine black pubescence ; Oth finely pnnctured, Ttli 

 more sparingly and finely punctured, these two with a 

 concolorous yelloAv ])u])escence. 



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 very long projecting 

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

 segment has a large triangular notch ; tlie a^leagus 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 individuals of this sex the mandil)les and 

 palpi are more elongate, and the elytra are iurnisiied near 

 the outside Avith a longitudinal fold or plica of variable 

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

 anterior tarsi are quite simple. 



Ega ; nine specimens. 



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

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

 pubescentibus ; antennis articulis duobus ultimis albidis. 

 Long. corp. 7 lin. 



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

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

 antennae 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 curved line of long 

 projecting hairs, and its hind margin is rather dee])ly 

 emarginate; the 7tli segment bears a large triangular 

 notch. The a^deagus is similarly formed to that of 

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

 the bifid processes at its extremity are shorter and more 

 rounded. 



Para; a single specimen found by ]Mr. Bates; it is 

 labelled " stump fungus." 



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

 males of I*, tricolor, and find its Ibrm to be completely 

 similar in the three, I cannot consider this individual to 

 be a mere variety of the Ega species. 



.3. Plocioptrrns nit/riprs, n. sp. ^« iger, nitidus, caj)ite, 

 prothorace, elytrisque cyaneis; antennis articulis idtimis 

 tribus testaceis, abdouiine apice rufo-testaceo; elytris 

 fasciis duabus, abdomine fascia singula ciuereo-tomeutosis. 

 Long. corp. 5^ lin.
