118 PSYCHE ' [December 



Thorax pale cadmium yellow, the mesoscutum, excepting a marginal path on 

 the lateral and caudal sides, is dusky, making a large triangular dusky marking in the 

 center of the mesothorax; this also involves the pronotum, and its edges are irregular; 

 the entire surface of the mesoscutellum is dusky, excepting the distinct median line, 

 and the extreme margins, and the large axillae are dusky discally, the margins con- 

 colorous with the ground color; also the discal surfaces of the parapsides dusky; 

 the mesal aspect of the mesopostscutellum silvery white; otherwise piceus, together 

 with the metanotum, excepting occasionally at the meson; tegulae pallid to dusky. 

 Mesothorax delicately polygonally sculptured, somewhat coarser and more irregular 

 on the scutellum; median line of scutellum longitudinally striate; the sculpture of 

 the axillae similar to that of the scutellum. Caudal margin of mesoscutum straight; 

 scutellum suboval. Thorax caudad of mesoscutellum, shining; about equal in 

 length to the abdomen or shorter; with a few dark setae scattered over its surface. 



Abdomen shining piceous black, ovate, the tip silvery white, and a broad trans- 

 verse fascia of silvery white across the basal third; this is inclined to be wider toward 

 the lateral margin; incisions of segments paler, but not conspicuous; at least the 

 ventrolateral aspect of the abdomen faintly lined; the dorso-lateral aspect with a 

 silvery sheen. Anal glands distinct, ovipositor shghtly exserted. 



Wings normal, the venation pale yellowish ; the whole of the distal half fuscous, 

 more deeply so in a subquadrate area immediately caudad of the stigmal vein, and 

 less so just distad of the stigmal vein along the costal border of the wing; the dusky 

 area involves about half of the distal third of the marginal vein, and is similar in 

 general to that in the species viurtfeldtii Howard, but broader and less regular in 

 outline; basal portion of the forewings under the submarginal vein very slightly 

 dusky; cilia less dense in the basal part of the wing, under the submarginal vein; 

 a triangular area just proximad of the basal margin of the fuscous area nearly naked, 

 excepting two or three rows of ciha just below the marginal vein, and two very faint 

 rows through the naked area; at least 5 setae arise from the cephahc edge of the 

 marginal vein, 7 from the submarginal, and 1 from the tegula. 



Hind wings normal, hyahne, the distal third of the submarginal vein (that portion 

 not touching the costal border) moniliform; submarginal vein bearing at least four 

 setae from its cephahc edge and the marginal from nine to eleven setae from its surface; 

 fore wings and hindwings densely, uniformly ciliate in the disk, the latter ha\dng at 

 least six or seven rows of cilia at the point indicated by a line drawn transversely 

 across the wing through the apical end of the marginal vein (usually from 6 to 9 rows). 



Entire legs pale cadmium yellow to pallid, the tibiae and tarsi marked as in 

 murtfeldtii Howard; apical tarsal joint blackish at the extreme tip; anterior femora,
