Nigra, arge^iteo Jiirta ; femoribns, tilnis, f arsis, petiolo, 

 abdominisqne segniento i° fere toto, rufis, alis Jiyalinis vel 

 fusco-hyalinis, apice fiimatis, costa testacea ; nervis nigris ; 

 abdomine ccEndeo. ?. Long. 17 — 19 mm. 



Similar to the preceding species, but smaller, with the 

 pubescence shorter and sparser, and of a more silvery tint ; 

 the wings without such a decided yellowish tinge, and with the 

 nervures blackish ; the first abdominal segment is red, except 

 at the apex, and the third antennal joint is shorter, not being 

 twice the length of fourth. Mandibles broadly red at the 

 base, which is striated ; clypeus punctured, densely covered 

 with a silvery pubescence ; its apex with a broad shallow 

 sinuation ; front and vertex shagreened, sparsely and shortly 

 pilose. Antennae with the base of first joint testaceous, the 

 flagellum covered with a pale pile. Pro- and mesonotum 

 strongly transversely striolated ; metanotum more closely 

 and not so strongly ; scutellum strongly longitudinally 

 striolated ; propleura perpendicularly striolated, meso- and 

 metapleura obliquely rugosely striolated ; the raised part of 

 the metanotum shield-shaped. The tubercles and the sides 

 of the middle segment densely silvery pilose. The second 

 joint of the petiole is black above at the base ; the apex 

 has a silky pile ; the hind coxae are white with a dense 

 silvery white pubescence ; the trochanters are red, blackish 

 towards the base and apex, the anterior broadly black at 

 the base ; the tips of four anterior tarsi and the posterior 

 from the base of the second joint blackish ; spurs blackish. 

 Alar cellules pretty much as in y4. biiddha. The ocelli do 

 not form a triangle ; the anterior not being placed very far 

 in front of the posterior. 



The clypeus and tegulae in some specimens are tes- 

 taceous ; the apex of the second joint of the petiole may be 

 black ; the basal joint of the antennse may be testaceous,
