yellowj and by the second abdominal segment being marked 

 with yellow at the base. In the presence of the two yellow 

 marks on the base of the second abdominal segment it agrees 

 with artifex and variegafa, from which it is otherwise very 

 distinct. 



Antennte dark rufous, darker above ; the scape yellow 

 below. Head daik rufous ; the clypeus, the inner orbits to 

 the top of the eye-incision, the upper half of the antennal 

 tubercle, the outer orbits (narrow above, broader below) from 

 near the top to the base of the mandibles, the palpi, the man- 

 dibles (except at the apex), a transverse line on the prouotum 

 above, one on its sides, the postscutellum, two large marks on 

 the metanotum, an oblique squarish mark under the teguUe, 

 a larger oblique one (narrowed at the base) on the lower side 

 on the apex of the mesopleura, a mark on the top of the 

 metapleurfe, triangularly dilated below, on the sides of the 

 mesosternuni is a large mark turned outwardly at the base 

 and largely dilated at the apex, on the apex is a larger 

 oblique mark, at the tubercles a smaller one, and on the 

 lower half of the metapleur^e is a large mark, incised in the 

 middle above, and the base of the propleurai, all clear yellow. 

 Scutellum nairowly furrowed in the middle from the base to 

 the apex ; the median segment widely but not deeply furrowed 

 down the middle. Wings fuscous-hyaline; the apex of the 

 costal cellule and the radial cellule smoky, especially above. 

 The four front legs yellowish, the trochanters, the femora in 

 front (except at the apex), the basal half of the tibite, and 

 the basal joint of the tarsi fuscous; the middle coxae broadly 

 on the inner side below, the basal half of the femora, the 

 basal two thirds of the tibiae and the tarsi black ; the hinder 

 legs similarly coloured, but with the black more extended. 

 Petiole dark rufous ; the sides (except at the apex) and a 

 mark on the sides of the dilated part, two large marks on 

 the sides of the second segment at the base, two large marks 

 on the base of the third, two smaller ones on the base of the 

 third and two large marks on the last segment, the sides of 

 the petiole beneath, a large mark (narrowed at the base) on 

 the base of the second, a large transverse line (dilated at the 

 sides) on the base of the third, and a narroweroue on the base of 

 the fourth segment, lemon-yellow. Thesides of the clypeus are
