1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 24/ 



Trachystola granulosa, Pascoe, op. cit. p. 351. 



Trachystola is placed at the end of this subfamily only provision- 

 ally ; its general form, sculpture, and colour point "to the Dorcadio- 

 nince, and, but for the presence of humeral angles, in that group it 

 would undoubtedly take its place. M, J. Thomson puts it between 

 Aderpas and Anamera in his " groupe Mesositce" a location, I 

 think, very far from natural. T. granulosa is apparently a common 

 insect at Sarawak. A second species is described by M. J. Thomson, 

 from Java.

Batocera victoriana, Thomson, Rev. et Mag. de Zool. 1856, 

 p. 529 ; Arch. Ent. t. 1. p. 23. " Frontispiece." 



Found also by Mr. Wallace in Borneo. The spots on the elytra 

 are of a fine vermilion during life.

This is also a Bornese species. Mr. Wallace found not less than 

 eighteen species of this magnificent genus ; some of them measure, 

 from tarsus to antennae, nearly a foot in length.

 Apriona germari. 



Lamia germarii, Hope, Zool. Miscell. p. 28. 

 The original specimens of this species were from Sylhet, but it 

 appears to be generally distributed in continental India. 



Thestus. 



Antennae subtus fimbriate. 



Prothorax lateribus hand spinosus. 



Tibiae anticee compresses. 



Mesosternum productum. 



Head transverse in front, not dilated below the eyes ; antennary 

 tubercles very robust, approximate at the base ; eyes rather large, 

 broadly emarginate. Antennae longer than the body, densely fringed 

 beneath, except the terminal joints ; the scape obconic, rather short, 

 strongly cicatricose at the apex ; the third joint the longest, the fol- 

 lowing to the sixth or seventh gradually shorter, the remainder about 

 equal. Prothorax not broader than the head, cylindrical, short, 

 slightly toothed at the sides. Elytra broad at the base, the sides 

 nearly parallel, shoulders produced. Legs nearly equal ; tibiae com- 

 pressed. Mesosternum toothed anteriorly. 



The closely fringed antennae, compressed tibiae, and general out-
