identified by Cameron for Colonel Nurse as anthracina, 

 Sm. ; but, as I have pointed out in other papers, that 

 insect is an Anthobosca and is Australian ; not Indian, as 

 stated by Smith and Bingham.

Long. $, 18 mm; (J, 17 mm. 



$. Cljrpeus sparsely but rather strongly punctured, with a low 

 median carina which does not reach the broadly truncated apex. 

 Head coarsely and closely punctured, more sparsely on the vertex 

 than on the front, antennal tubercles well defined. Scape smooth 

 above, beneath punctured, with long pale fulvous setae towards 

 the apex. Pronotum coarsely and closely punctured, subcarinate 

 longitudinally in the middle; scutellum and mesonotum rather 

 more sparsely punctured; pleurae more finely and shallowly 

 punctured. Median segment subopaque, with a longitudinal 

 impressed line on the dorsal surface, the puncturation shallow and 

 obscure, finer at the base than at the apex, the posterior slope 

 shallowly punctured-rugulose, the sides of the segment very finely 

 and closely striated and clothed with short white pubescence. Abdo- 

 men shining, sparsely punctured, more closely on the fourth and fifth 

 than on the basal segments, ventral segments more coarsely punctured 

 than the dorsal. Sixth dorsal segment closely longitudinally striated, 

 the apical margin broadly smooth and rather broadly truncate at 

 the apex. Second abscissa of the radius as long as the third, first 

 recurrent nervure received close to the middle of the second cubital 

 cell, second just before two-thirds from the base of the third cubital 

 cell> Basal joint of the hind tarsi with a close row of hairs beneath 

 mingled with a few spines. 



Q. Clypeus finely punctured, clothed with white pubescence.
