 median lon^ntudinal carina ; abdomen very closely and 

 minutely punctured ; mesopleurai swollen below, but not 

 tiiberculate ; vagina strongly exserted. Humeral cell of the 

 fore wing divided beyond the middle by an almost perpen- 

 dicular feebly curved nervure. Third abscissa of the radius 

 twice as long as the second.

This is nearly allied to C. viagrettii, Konow, which occurs 

 in the same locality, but differs in the much paler colouring 

 of the thorax and abdomen ; in the longitudinal carina of the 

 propodeum, which almost reaches the apex, but in magreltii 

 is only represented by a tubercle at the base ; in the less 

 strongly swollen mesopleurpe, and in the black antennae and 

 liind tibia3 and tarsi.

? . Clypeus emarginate ; labrum long, narrowly rounded 

 at the apex and sparsely punctured. Eyes converging 

 toward the clypeus ; antennae clothed with \ery short black 

 hairs, the third joint about one-quarter longer than the 

 fourth ; frontal sulcus with strongly raised lateral carinaj 

 which are raised into rounded tubercles above the base of the 

 antennae, and extend posteriorly to the hind ocelli ; vertical 

 area broader posteriorly than long, but as long as the ante- 

 rior breadth, finely and closely punctured and divided by a 

 very shallow longitudinal groove. Thorax finely and closely 

 punctured ; acutellum raised into a conical tubercle ; the 

 mesopleurae produced into a large blunt tubercle below, very 

 distinctly carinate behind the tubercle; mesosternum witli 

 an acute tubercle on each side before the intermediate coxie. 

 The fuscous border of the fore wing reaches te the apex of 

 the stigma.

This belongs to the group of T. xanthoptera, Cam., and 

 may be distinguished from otiier species of the group by the 

 wholly black antennae ami tlio wholly ochraceous abdomen.
