apices attenuate ; black, with the flagellum basally rufescent, and 

 scape flavous, beneath. Tliorax with long pubescence ; mesonotum 

 finely and sparsely punctate, notauli inconspicuous ; metathorax 

 gradually declivous, finely punctate and discally nitidulous ; lateral 

 carinae alone traceable ; a strong carina on either side of the 

 basally wanting petiolar area ; basal area indicated and subcircular ; 

 spiracles elongate, vertical and not small. Scutellum subglabrous, 

 immaculate and not convex. Abdomen elongate fusiform, broadest 

 behind its centre and with long white hairs ; first segment very 

 gradually dilated throughout", its basal half with two parallel 

 carinae and discally sulcate to the central spiracles, thence pilose

and obsoletelv punctate ; second segment slightly longer than 

 apically broad, with its apex, whole of third segment, and basal 

 angles of the fourth, dull red ; ventral valvulae exserted and not 

 large. Leys black, with the femora subincrassate ; anterior tibiae, 

 tarsi and inner side of front femora, testaceous ; hind tibiae, except 

 at base and apex, testaceous ; hind tarsi with the basal about as 

 long as the apical joint, and double the length of the second. 

 Wings ample and hyaline ; tegulae and stigma infuscate ; areolet 

 entirely wanting, with the radial nervure curved above it; nerTelltis 

 postfurcal and intercepted at its centre. 



Length 12 miliim. 



UKITED PROVINCES : Mussoori, 7000 ft., x. 06 (H. M. Lefroy). 



Type in the Pusa collection. 



The very distinctly sinuate radial nervure is remarkable, and 

 exactly resembles that of Catoglyptus fortipes, Grav., to which it 

 is also allied in its unusually stout femora ; but the equally biden- 

 tate mandibles, subsessile abdomen and the structure of the 

 nervellus preclude its inclusion in that genus. It is also very 

 distinct from most species of Tryphon in the complete absence of 

 an areolet and metanotal areae. 



Described from a single male.
