not mucli, narrowed towards the apex and broad bands on 

 the S'*^ and 4"' segments and the stenimaticum, black; the 

 legs of a paler testaceous colour than the body ; wings clear 

 hyaline, the nervures and the basal two-thirds of' the stigma 

 fuscous, the apex of the stigma white. (^. 



Length 3 mm. ; terebra two-thirds of the length of the 

 abdomen. 



Ceylon (Nietn er). 



Head and thorax smooth, covered with short white pubes- 

 cence. The 2"'\ 3'"'^ and 4"' abdominal segments finely, closely 

 transversely striated, the striœ on the 2"'^ running into reti- 

 culations. The P^ abscissa of radius one half the length of 

 the 2"'^ and as long as the 2"'^ transverse cubital nervure. 

 There is a faint violaceous cloud in the apex of the wings. 



Pegarthrum carinatus sp. n. 



Head, thorax, legs and basal segment of abdomen rufo- 

 testaceous as are also the palpi and mandibles, the antennal

 at the base, the costa and nervures dark testaceous, the radius, 

 cubitus and stigma black. Apices of 3^'*^ , 4"^ and 5^'^ abdo- 

 minal segments dark testaceous, the apical entirely of that

 gradually finer ; the 2"'^ with a distinct keel down the centre, 

 the 1^' with a weaker one ; it is about one half longer than 

 the 2"*^, centre of metanotum with a keel down it, the keel 

 in a shallow furrow, the apical slope with 2 transverse stout 

 curved keels intersecting the central one ; the surface bears 

 shallow punctures. The 3''' abscissa of radius is curved upwards 

 and is a little longer than the 2^^'^ ; the recurrent nervure is 

 received in the apex of 1^* cubital cell. The enlarged 2"*^ 

 joint of the maxillary palpi is twice longer than it is wide, 

 is roundly narrowed at the base, the apex transverse, with the
