llie apex of tlic cellule ; tlio third transverse cubital uorvurc 

 is broadly rounded on the lower side. The back of the 

 abdomen has a brownish tinge ; the hair does not form 

 distinct bands, but this may be owing to rubbing ; there is a 

 transverse furrow near the base of tlie apical fourtii of the 

 first segment, and a similar one shortly behind the middle of 

 the second; thea})ical rima is brownish. The ventral surface 

 is ratlicr thicklj' pilose; the dorsal surface is impunctate. 



The teguUw have the basal half black, the apical brownish; 

 there is a wide furrow on the hinder edge of the propleuraj, 

 extending behind to beyond their middle; the pleuriB below 

 this aie striated ; the clypeus is separated from the face by a 

 transverse furrow ; the face is roundly convex. 



A distinct s])ecies, readily known by the area on the median 

 segment not being cletined behind and by its having a few 

 jriegular longitudinal stria', by the furrows on the mesonotum 

 with the incision at the base, by the transverse furrows on the 

 basal t-wo segments of the abdomen, by the form of the base 

 cf the thorax^ and by the keeled apex of the median segment. 



In Bingham's arrangement the species would come in near 

 H. albescens. 



HaHctus cei/Iom'cus, sp. n. 



Black, the vertex and mesonotum with a slight but distinct 

 brassy tint, the base of the median segment striated ; the hair 

 on the head and thorax white, the base of the abdominal 

 segments banded narrowly with white pubescence. ? . 



Long. 8 mm. 



Hab. Ceylon {Rothney). 



Antennai black, slightly brownish towards the apex. 

 Head moderately shining, smooth ; the front and vertex 

 covered with long fuscous hair, this being also the case with 

 the face and clypeus ; the outer orbits are covered with white 

 liair. The clypeus is distinctly separated from the face by 

 a sutuie; its apex is transverse, distinctly and broadly 

 furrowed, and fringed with long rufous hair. Pro- and 

 mesonotum with the scutellum shining, impunctate, and 

 covered with fuscous hair ; the postscutellar region is thickly- 

 covered with white pubescence. The median segment at the 

 base is not so brassy in tuit as the mesonotum , it is there 

 closely longitudinally striated ; its sides are more obliquely 

 striated ; it is not defined behind ; its apical slope has its 

 upper three fourths furrowed in the centre, the furrows being 

 obliquely widened on the top ; the sides are keeled. Tlie 

 ])ropleuKe project broadly behind above, the projecting part 

 Ijecoming roundly narrowed towards tiie apex, 'i'iie hair on 

 the femoia and tibiic is white, on the underside of the tarsi it 

 is rufous.
