128 Psyche [October 



parallel, the pronotum and epinotum each forming about a third 

 of the dorsal surface, the remaining third being formed by the 

 mesonotum, scutellum and metanotum; the mesonotum very 

 small, scarcely broader than long. In profile the thorax is flat- 

 tened above, rounded in front and behind, the base of the epino- 

 tum long and straight and passing through a strong curve into the 

 short, vertical declivity. Petiole from above nearly four times as 

 long as broad, but little broader behind than in front, with nearly 

 parallel sides ; in profile feebly and evenly convex from before back- 

 wards, ventrally compressed and with an elongate blunt tooth 

 near the middle. Postpetiole twice as broad as the petiole, some- 

 what longer than broad, subtrapezoidal, somewhat broader behind 

 than in front, with convex rounded sides. Gaster long and slender, 

 the first and second segments longer than broad, the first but little 

 broader anteriorly than the postpetiole. Legs short, femora, 

 especially the fore pair, flattened and dilated. Wings very short, 

 scarcely 4 mm. long. 



More shining throughout than the worker, the fine punctures 

 being less dense, even on the thorax and gaster. 



Hairs and pubescence much sparser than in the worker, the 

 pubescence very dilute; only the base of the first gastric segment 

 somewhat pruinose. 



Brownish yellow; mesonotum, scutellum and epinotum some- 

 times a little darker; a broad spot at the base of the first gastric 

 segment and nearly the whole dorsum of the fourth segment fus- 

 cous, or blackish; the middle and hind femora slightly infuscated; 

 a minute spot in front of the insertion of the fore wing, one at 

 each ocellus, and the teeth of mandibles black. Wings grayish 

 hyaline, strongly iridescent, with pale brown veins and dark brown 

 pterostigma. 



Male. (Fig. 3.) Length 4.6-5 mm. 



Head slightly longer than broad, subelliptical, with straight 

 posterior border and behind the eyes with straight sides converging 

 to the posterior corners. Eyes rather convex, about half as long 

 as the head; ocelli large. Cheeks very short. Anterior clypeal 

 border sinuately excised on each side, its middle produced as a 

 distinct, bluntly pointed lobe. Mandibles convex, their apical 

 borders finely and indistinctly denticulate. Frontal carinse short, 

 much more widely separated than in the worker and female.
