Psyche 
[February 
tened dorsal ly, much wider than the thorax; the four basal 
segments together much shorter than wide; the succeeding, 
apical segments much narrower, gradually decreasing in width, 
partly retractile as a telescope-shaped ovipositor. The last 
segment ends in two comparatively wide, long, straight, bluntly 
pointed lamellae. Legs moderately heavy; femora slightly 
thickened, more distinctly swollen on the forelegs. 
Wings moderately long and narrow, not quite four times as 
long as wide. Costal margin nearly straight; the posterior 
margin gradually narrowed in its basal quarter, where a narrow, 
but distinct alula extends from the axillary excision to the base 
of the wing. Wings distinctly and uniformly smoky; veins 
dark clove-brown; the epaulets and basicosta black; the epaulet 
with a few black hairs. Venation of the usual type of the genus; 
fourth posterior cell with a short petiole at the base; sixth longi- 
tudinal vein very slightly undulate (nearly as in arnoldi); no 
“bulla” at base of second vein; axilla^ vein not developed 
beyond axillary incision. 
Length not including ovipositor (to apex of tergite 4), 
11.5 mm.; greatest width of abdomen, 6.5 mm.; length of 
proboscis, 11.5 mm.; length of wing, 15 mm.; width of wing, 
4 mm. 
This species is exceedingly close to Stenobasipteron gracile 
Lichtwardt, much more so than S. arnoldi. There are, however, 
a number of differences: the body is more thickset; the legs are 
stouter; the anterior ocellus is smaller, not quite twice the size 
of a posterior ocellus; the third antennal segment has a different 
shape; the style is only two-jointed; the sixth longitudinal 
vein is quite straight; the lamellae of the ovipositor are broader, 
etc. It is difficult to believe that these discrepancies are all due 
to individual variation. Moreover, the unknown male may 
show further characters.

The original description of this species (Deutsch. Ent. 
Zeitschr., 1910, p. 615) is extremely brief and is reproduced here 
for the benefit of Rhodesian entomologists. It is said to be so
