tarsal claws ■wdth four inner teeth, the basal portion stout and sub- 

 dentate apicall}^ so at some angles there appear to be five teeth. 



The two species placed in Senoclia by Kirby certainly belong there. 



A gootl series of Senoclia caerulea C^ameron has kindly been given 

 to the National Museum by Prof. E. E. Green. 



SENOCLIDEA, new genus. 



Related to Senoclia Cameron, but may easily be separated from 

 that genus by the dentation of the tarsal claws, longer third antennal 

 joint, and position of the transverse median. In the dentation of the 

 claws, and venation Senoclidea is like Parazarca Ashmead, but may 

 be readily sei)arated from it by the metapleurse (in Parazarca the 

 metepisternum and metepimeron are about the same size, the wing 

 process is composed of both plates, and is not an elongate single 

 piece). Nesotomostethus Rohwer has the antennae and metapleuraj 

 different. 



Belongs to Blennocampini. Clypeus truncate; malar space want- 

 ing; eyes converging to the clypeus; lateral ocelli below the supra- 

 orbital line; antennal furrows and ocellar basin present; antennae 

 thickening apically, third joint longer than the fourth, pediceilum 

 widened apically, not much longer than wide; transverse median 

 slightly basal of middle of cell; hind wings with one discal cell, the 

 lanceolate cell with a long apical petiole; metepimeron smaller than 

 the metepisternum; third wing process single, elongate, narrow; 

 tarsal claws robust, cleft apically; basitarsis III subequal with the 

 three following joints. 



Type. — Senoclidea amala Rohwer. 



SENOCLIDEA AMALA, new species. 



Of the two species of Senoclia this is nearer purpurata (Smith), but 

 the color of the legs will separate it from that species. 



Male. — Length 8 mm. Supraclypeal foveae poorly defined; mid 

 die fovea deep, large, walls straight, triangular in outline, the base 

 of the triangle being above, and open below; antennal furrows 

 nearly interrupted at the crest, but otherwise complete; ocellar 

 basin well defined, not inclosed below, a deep fovea just below ante- 

 rior ocellus; postocellar furrow present; postocellar area a little 

 wider than long, defined laterally by foveas rather than furrows; 

 postocellar line much shorter than the ocellocular line; apical joints 

 of the antennae well defined, the apical joint nearly twice as long as 

 the preceding, which is but little longer than wide; scutellum flat; 

 stigma elongate, rounded below, truncate apically; third cubital cell 

 longer than the second; transverse median a little basad of middle; 

 tarsal claws deeply cleft and with a large, blunt inner tooth; hypo- 

 pygidium broadly rounded apically. Blue-black, the abdomen pur-
