190 MESSRS. C. HORNE AND F. SMITH ON HYMENOPTERA 
graphie des Guépes solitaires,’ and named Humenes affinissima from its close resemblance 
to the European species E. coarctata and E. pomiformis; but I have nothing to justify 
my considering it to be so. 
2. PTEROCHILUS PULCHELLUS. (Plate XXI. fig. 80.) 
Female. Length 3 lines. Black, ornamented with yellowish-white markings; the 
basal segment of the abdomen red. 
Head—a line behind the eyes, the sides of the clypeus, an oblong spot above it, the 
base of the mandibles and the scape in front yellow white. A transverse line on the 
thorax in front, the tegule, a spot beneath the wings, and the sides of the scutellum 
and postscutellum yellowish white; the wings hyaline and iridescent; the femora and 
the tibia within pale ferruginous, the coxz white in front, the tibize and tarsi white and 
more or less stained with pale ferruginous. Abdomen—the first segment red, small, 
and campanulate, much narrower than the second; the posterior margins of all the 
segments white, and a small ovate spot on each side of the second segment; beneath, 
the second segment with a white apical margin. 
Male. Rather smaller than the female, and closely resembling that sex, but having 
the clypeus immaculate (the female has a black spot), and the second abdominal segment 
without the two ovate white spots.

Worker. Length 9 lines. Black, pubescent, head yellow, the abdomen with orange 
bands, the legs and antenne ferruginous. 
Head sulphur-coloured; the face above the clypeus as high as the posterior ocelli 
black; the emargination of the eyes obscurely yellow; a reversed bell-shaped yellow

Thorax black, with sometimes a very narrow orange line on each side of its anterior 
margin; wings fulvo-hyaline, with the anterior margin of the superior pair fusco-

Abdomen with the first segment bordered with a broad orange band occupying half 
its width; the second segment with a very narrow orange band on its apical margin;

spots unite with the black basal portion of the segment, which is sometimes partly visible 
also; the apical margin of the fourth segment, and the fifth and sixth entirely, orange- 
yellow; the abdomen yellow beneath from the middle of the second segment to the 
apex.
