HORN EXPEDITION—COLEOPTERA. 
tubercles. The suture and each of the costie bear a close-set row (partially 
doubled on the first costa) of small granules, while the wide space between the 
suture and first costa and between the first and second costie bears a row of 
distantly-placed and manifestly larger granules. The brownish pubescence is denser 
and more conspicuous on the head than elsewhere, and a feebly-defined longi¬ 
tudinal vitta of paler brown pubescence runs down the forehead. I may add that 
Mr. T. G. Sloane, who has made a special study of the Aviycterides, has done me the 
favour of inspecting this insect, and is of opinion that Sir W. Macleay would have 
placed it among the T. granulati near T. nodulosus.

This is a distinct species, notable for its red legs and the very peculiar 
structure of the intermediate tibiae in the male. The sculpture of its upper 
surface resembles that of T. rugiceps, Mach, but the tubercles are smaller on both 
prothorax and elytra ; consequently the rows of tubercles on the elytra are a little 
more widely separated one from another, leaving room for a distinct intermediate 
row of granules.
