74 Mr. D. Sharp s Contributions to the 



as to form two short, stout, almost confluent teeth, and it 

 has also at each outer anofle a rather long-er and more 

 slender pomted spine. 



Rio Purns, 13th October, 1874, and Gan-ao, 11th 

 November, 1874 ; a single male from each locality, cap- 

 tured by Dr. Trail. 



4. Gyrophcena Icevis, n. sp. Sat convexa, nitidula, 

 nigro-picca, antennarum basi pedibusque testaceis; pro- 

 thorace disco quadripunctato ; elytris parce punctatis. 

 Long. Corp. 1 lin. 



In the male the hind margin of dorsal plate of the 7th 

 segment of the hind body is armed in the middle with tAvo 

 fine, pointed, approximate spines, and on each side with a 

 stouter, distinctly incurved spine ; the hind margin is most 

 prominent in the middle, so that though the outer spines 

 are considerably longer than the two middle ones they do 

 not project farther backwards. 



Garrao, 11th November, 1874; two male individuals 

 found in fungus by Dr. Trail. 



Obs. — This species is excessively closely allied to G. 

 parca, and agrees almost exactly with it in most respects ; 

 but it is a little larger and more convex, and is readily 

 distinguished by the different character of the teeth on the 

 7 th segment of the hind body in the male. 



5. Gyroph(Bna juncta, n. sp. Picea, nitidula, anten- 

 narum basi pedibusque testaceis; elytris abdomineque 

 castaneis, hoc ante apicem piceo, illis versus angulos ex- 

 ternos infuscatis ; prothorace valde transverso, disco quadri- 

 punctato, elytris apicem versus fortiter punctatis. Long, 

 corp, 1 lin. 



Antenna? only moderately stout, the first four joints 

 yellow, the others infuscate ; 3rd joint small, very much 

 smaller than 2nd; 4th minute; 5 — 10 differing little from 

 one another, transverse, but not strongly so ; 11th obtuse. 

 Head pitchy, with some fine bvit distinct punctures on each 

 side ; it is much nan-OAver tlian the thorax. Thorax very 

 transverse, the base rounded, the sides only a little nar- 

 rowed toAvards the front ; it is of a shining intchy colour, 

 and on the disc has four rather fine punctures. Elytra 

 distinctly longer than the thorax, of a chestnut-yellow 

 coloiu*, but infuscate at the sides towards the hinder angle ; 

 they are shining, and have some unevenly distributed
