FAMILY CERAMBYCIDAE 377 



hair or tufts on the front of the head and basal joint of antenna, joints 2 and 3 and 

 thighs and tibiae of legs densely pubescent ; apices of elytra fringed with hairs, giving 

 them a frayed appearance. On vertex of head, on a median longitudinal line on prothorax, 

 and on elytra, the dense pubescence is placed in the form of elongate yellow or brown 

 longitudinal lines and stripes, the lines curving inwards from shoulders and outwards again 

 in apical fourth. Length, 30 mm. to 55 mm.

Madras, who reported that the beetles had been found 



ringing branches of ]VrigJitia tinctoria. The beetle rings stems and branches 

 in a manner similar to that of Sthenias grisator, and for the same purpose. 

 This appears to be all the record we have at present of this insect. 



The beetle was forwarded to me from Taunggyi by Mr. H. W. Watson 

 with the oak borers Massicui and Ncocerainbyx, but the species of tree 

 infested in that locality by the beetle was unknown.
