Psyche 
[September-December 
measuring 2.9 X as long as wide; tibiae wholly without spines. 
Fore wing with transverse median vein considerably basad of 
origin of basal vein; radial vein strongly angled at junction of 
second intercubital vein (first intercubital absent, resulting in 
a very long first submarginal cell); second submarginal cell slight- 
ly wider than high; hind wing with transverse median vein erect, 
forming a right angle with anal vein, meeting media far basad 
of origin of cubitus; anal lobe extremely small. 
Remarks. — This striking form resembles mostly closely the 
Central American species insolitus Evans and delicatus Turner. 
It differs not only in the possession of only two submarginal 
cells, but also in having the head ferruginous, the postnotum 
extremely short, and the tibiae wholly without spines.

Description of type female. — Length 9.6 mm; fore wing 7.0 
mm. Head black, except palpi dark brown, mandibles rufotes- 
taceous on apical two-thirds, scape with a large white spot on 
upper surface apically; thorax and propodeum entirely rufous 
except propleura black; abdomen black except for large paired 
white spots on tergites 2 and 5 and a median white spot on 6; 
legs variegated, coxae mainly black but with some white api- 
cally, middle and hind pair rufous basally; femora black except 
front and middle pair streaked with rufous; tibiae black except 
front pair rufotestaceous on inner surface, middle and hind pair 
spotted with white near base; tarsi fuscous. Fore wings strongly 
twice-banded, a broad band crossing wing at basal vein and an- 
other at marginal cell, membrane tinged with yellowish basally 
and between the two bands, at tip of wing more whitish; hind 
wing subhyaline, slightly darker apically. Clypeus broadly con- 
cave apically. Malar space about 0.4 X as long as width of man- 
dibles at their base. Front narrow, middle interocular distance 
0.55 X head width; upper interocular distance 1.1 X lower inter- 
ocular; eyes densely hairy; postocellar line 1.3 X ocello-ocular 
line. Third antennal segment 0.54 X upper interocular distance. 
Postnotum medially about half as long as metanotum; slope of
