Female. — Differs from lohata lobaia as follows: 
Head. — A yellowish, or yellowish-white spot, or longitudinal 
line usually on each side of the i)osterior portion of the vertex- 
plate, and very often a minute elongate spot at the terminus of 
each arm of the epicranial suture; the black spot on the posterior 
half of the cheek sometimes coalesces with that along the upper 
part of the eye; basal segment of antennae usually black inside, 
and the yellowish line outside sometimes absent. Supra-antennal 
ridges from moderately prominent to prominent. 
Thohax. — Margin of pronotum not interrupted antero- 
dorsally; V-spot on prescutum very often not complete poste- 
riori}^; the following additional parts yellow or yellowish white: 
a short longitudinal line on the mesoscutum on each side of the 
posterior portion of the prescutum, a triangular spot at the 
posterior end of the mesoscutum immediately in front of each 
anterior angle of the mesoscutellum, the anterior margin of the 
mesoscutellum in part rarely, a small spot on the metascutum 
behind and under each cenchrus, and the greater mesal upper 
half of the meta-postscutellum; as a rule only a small spot at the 
upper anterior angle of the meso-episternum, and very often a 
small yellowish-white, or straw-colored spot at the posterior end 
of the pectus on each side of the median longitudinal suture. 
Mesoscutellum from slightly to moderately convex; meso-epister- 
num from moderately to fairly sharply pointed. 
Abdomen. — Venter with only the terga straw color. 
Legs. — Trochanters black above, sometimes almost entirely; 
anterior femora usually black behind; very frequently interme- 
diate femora black except more or less before; the black on apical 
portion of posterior tibiae often more extensive above — about 
half-way up toward base. 
Wings. — Fore wings sometimes hyaline; costa not brown. 
Described from type and five paratypes. Two of the para- 
types are in the collection of the Boston Society of Natural His- 
tory, two in the collection of the American Entomological Society 
at Philadelphia, and the fifth is in the collection of the Connecti- 
cut Agricultural Experiment Station at New Haven, Connecticut.
