oral margin, a little less than half as long as body, distinctly 

 clavate ; the scape slender, compressed ; pedicel as long as the 

 first three funicle joints ; the funicle five-jointed, all joints short, 

 increasingly transverse, the fifth nearly twice as wide as long ; 

 club large, oval, not much wider than the last funicle joint and 

 as long as funicle and pedicel combined, composed of two joints, 

 the basal one being much shorter ; mandibles ( fig. 3, E ) with 

 three long, acute teeth, the ventral one far more basal, the upper 

 two at the apex, with the middle one slightly longer. Thorax 

 small, the visible portion of dorsum hardly more than one-half 

 as long as abdomen ; pronotum very large, fully as long as the 

 mesoscutum and scutellura combined ; mesoscutum very short and 

 transverse, about four times wider than long ; scutellum also short 

 and transverse, a little longer than the scutum, the axillae coa- 

 lesced with it, the sutures not at all visible unless insect is 

 mounted in balsam ; metathorax and propodeum concealed by 

 the base of the abdomen, which overlaps the posterior part of 

 the thorax so that the apex of the first abdominal segment and 

 the posterior margin of the mesopleura lie in the same vertical 

 plane ; wings either absent or vestigial, the front pair visible in 

 some specimens as minute, linear scales, no longer than the scu- 

 tellum, bearing two bristles at apex and one on the side, hind 

 pair of wings apparently entirely absent ; legs short, normal, the 

 middle tibial spur slender, tapering, a little shorter than the first 

 tarsal joint, hind tibiae with two spurs, the smaller one half as 

 long as the other. Abdomen large, oval, depressed, the first seg- 

 ment shortest, the second longest ; ovipositor shortly protruded, 

 otherwise enclosed by the fifth sternite, which reaches to the apex 

 of the abdomen but does not become at all compressed ; vibrissal 

 plates situated at the apical fourth, the vibrissae reaching about 

 to the apex. Surface of head and body nearly smooth, or very 

 finely alutaceous, the frontovertex with extremely minute, shal- 

 low, scattered setiferous punctures; pubescence short, very 

 delicate, pale colored, and hardly visible except under high 

 magnification ; coloration yellow, non-metallic, but with a pearly 

 luster. 



MALE 

 Much like the female, except that the abdomen is consider- 

 ably shorter and wider, the antennal scape (fig. 3, D) a little 

 wider and the club considerably longer and solid.
