Striated, at the apex of this space there is a strong pit or excavation ; the 

 posterior face irregularly striated; on the sides punctured, with an obHque, 

 foveolate furrow ; hind tibiee and tarsi distinctly spinose ; the anterior 

 femora much broadened, flattened or depressed on its inner side on the 

 basal portion ; wings subhyaline, iridescent ; the marginal cell and the 

 apex of the wing, fuscous. Abdomen shining, petiolate — that is, the first 

 segment is much narrower than the second, broader at the apex than at 

 the base, segments 3-5 above and 2-7 beneath with large, scattered 

 punctures, those on the first segnient dorsally and ventrally, and on the 

 second segment above, not so distinct ; last ventral segment bifid. Black; 

 clypeus, labrum, mandibles, except apex, face, inner orbits broadly, scape 

 and third antennal joint beneath, the second joint entirely, posterior orbits, 

 anterior margin of collar, prothorax above, tubercles, anterior portion of 

 mesopleurpe, spot beneath tegulse, an oblique line on the dorsulum by the 

 tegulae, scutellum, post-scutellum, a large spot on each side of the posterior 

 face of the metathorax, legs, except the upper surface of the coxse, 

 trochanters and femora, a broad band on apical margins of all the 

 abdominal segments above, the one on second segment broadest, and on 

 the ventral segments, with exception of the base, all yellow ; the greater 

 part of the antennae and the posterior tibiae and tarsi, in part, brownish. 

 Length, 9 mm. 



Nevada. Four specimens. Related to notabilis, Handl., from Mexico, 

 but differs in having the tenth antennal joint excised beneath, etc. 



GORVTES RUFOCINCTUS. 



5 . — Ocelli placed in a triangle, the posterior pair connected by a 

 curved furrow; clypeus with large punctures, its anterior margin incurved; 

 eyes diverging towards the clypeus ; front having the appearance of being 

 exceedingly finely granulated, the furrow distinct ; antennae long and 

 slender, the third joint much longer than the fourth. Thorax shining, the 

 dorsulum with exceedingly fine and close punctures; the mesopleune with 

 large, shallow, scattered punctures ; sutures between the dorSulum and 

 scutellum, and the scutellum and post-scutellum, distinctly foveolate ; en- 

 closed space on metanotum large, channelled medially and covered with 

 beautiful, radiating striae ; apical portion of posterior face roughened, the 

 basal portion smooth, shining ; wings subhyaline, nervures and stigma 

 black ; a fuscous cloud fills the marginal, second submarginal and part of 

 the third discoidal cells ; transverse medial nervure of hindwing confluent 

 with the cubital nervure ; medial and posterior tibiae and tarsi distinctly
