LONGICORN COLEOPTERA FROM BURMA 77 



pearanee. The prothorax is rather feebly and not very closely 

 punctured, it is slightly rugose towards each side of the disk, 

 and on the middle of the disk bears four minute granule-like 

 tubercles. The elytra are strongly and closely punctured, the 

 punctures being only partially hidden by the not very dense 

 pale-grey pubescence. The antennae are about equal in length 

 to the body. The single specimen taken is probably a female.

The antennal tubercles are somewhat more prominent on the 

 inner side and separated by a narrower interval (somewhat 

 V-shaped when looked at from above) than is usual in the genus 

 Sybra. The elytra also are more strongly declivous posteriorly. 

 Each of the intermediate cotyloid cavities, though in fresh spe- 

 cimens appearing to be completely shut off from the epimeron 

 on the outside, in reality extends out to it; the narrow outward 

 extension being occupied by the trochantin when the femur is 

 turned backwards. Lacordaire has laid stress upon the closing 

 in of the intermediate cotyloid cavities in the group to which 

 Sybra belongs. « Pris dans son ensemble, il est très-voisin des 

 Apomécynides et n'en diftère essentiellement que par la ferme- 

 ture des cavités cotyloides intermediaires » . Tliis is not however, 

 a reliable character. A careful examination of the different species 

 of the Ptericoptides will show that in very few% if any, are the 

 intermediate cotyloid cavities completely shut off from the meso-
