284 Mr. P. Cameron on new 



with white hair ; the calcaria black. Wings dark fuscous 

 violaceous ; the nervures and stigma black. Abdomen black, 

 shining, finely punctured, the apical segment thickly covered 

 with long black hair, except on the apex; the ventral seg- 

 ments are fringed with white hair. 



Comes near to T. rufofemorala and T. khasiana, but these 

 species are both smaller and have the middle femora red. 

 The upper half of the second transverse cubital nervure is 

 roundly curved outwardly. 



Tip Ilia denticula, sp. n. 



Long. 12 mm. 6 . 



This species comes near to T. canaliculata, but is more 

 slenderly built ; the depression on the apex of the median 

 segment is not so wide nor so deep, nor is it so regularly 

 striated ; the basal abscissa of the radius is distinctly angled 

 above the middle, not gradually rounded as in canaliculata ; 

 the lower abscissa of the apical part of the radius is longer, 

 and there is a more distinct angle formed by it with the 

 second recurrent nervure. 



Head opaque, closely rugosely punctured and thickly 

 covered with long white soft hair; the front is indistinctly 

 keeled in the middle. Clypeus closely rugosely punctured, 

 its apex smooth and transverse. Mandibles black, as are 

 also the palpi. Pro- and mesonotum shining, closely punc- 

 tured (except on the apex of the former) ; the scutellum and 

 postscutellum are similarly punctured. Median segment 

 irregularly coarsely aciculated ; the three keels extend to the 

 apex, but the outer become weaker towards the apex, which 

 is broadly depressed, shining, and bears a stout longitudinal 

 keel in the centre. The apical slope is coarsely aciculated 

 and keeled down the middle. The basal half of the pro- 

 pleuraj is aciculated and obscurely striated ; the mesopleurse 

 strongly and closely punctured; the metapleura; striolated, 

 aciculated at the base. Wings uniformly fuscous, with a 

 violaceous tinge ; the nervures and stigma black ; the trans- 

 verse basal nervure is thickened near the top, the transverse 

 median is received shortly behind it ; both the recurrent 

 nervures are received shortly beyond the middle. There is a 

 distinct curved broad tooth on the underside of the petiole 

 at the base, from which a keel runs to the middle. The 

 hair on the apical and on the ventral segments is long and 

 white.
