44 Psyche [April 
narrowed and truncate posteriorly; eyes large and prominent; 
prothorax long, narrowly conical in outline, but the sides bulging, 
-the whole thorax very long and narrow; metathorax posteriorly at 
sides with short but distinct teeth, four in all; anterior femora with 
upper margin concave, lower convex; hind femora very broad, cunei- 
form, the large end basad, the basal upper corner very prominent, 
obtusely rectangular; abdomen with a slender petiole, but rapidly 
widening, as in living forms. Hind tibiz with a single long spur. 
The following measurements are in microns: greatest width of 
head 440; length of eyes 224; width of thorax in middle 368; width 
first abdominal segment 592. 
Burmese amber, from R. C. J. Swinhoe. In the same slab as the 
type of Winnertziola burmitica, and 7.5 mm. from it. The speci- 
men shows the ventral view, and the palpi are not visible, so the 
generic reference may be somewhat doubtful. The insert is, 
however, of this immediate alliance, and the relatively large 
laterally placed eyes indicate a more primitive type than typical 
living Scleroderma. Species of this genus (S. tuberculata Magr. and 
S. luteicolle Kieff.) are known in the existing fauna of Burma. The 
great antiquity of the genus is indicated by the fact that although 
the females are wingless, species occur on the most remote islands; 
the Hawaiian Is. (many species), Guam, the Seychelles and St. 
Helena. 
Apenesia electriphila sp. nov. (Bethylide). 
o. Length about 2.5 mm.; black or piceous; wings clear, with 
light ferruginous stigma and nervures, venation typical for genus, 
stigma large, marginal cell open at end. Mandibles bidentate, the 
teeth stout; labial 
palpi 3-jointed; an- 
tennz apparently 
12-jointed, but 
turned down at 
ends, and possibly

flattened, curved; 
flagellar joints short and broad, antennal joints 2-7 longer than
