about equal to greatest distance between eyes; malar space very short 

 only one-seventh length of eye, cheeks strongly convergent, smooth 

 polished median line on spur, distance across scapal furrow at base 

 nearly three times distance from edge of furrow to eye ; vertex broad, 

 rugosely punctate with striated polished areas on either side of lateral 

 ocelli and in front of median ocellus ; eyes deeply emarginate ; posto- 

 cellar space two times ocellocular, occipital carina low ; antennae 12- 

 segmented, scape about as long as following three segments, first 

 funicular 1.3 times pedicel, tliird, fourth, and fifth subequal, the rest 

 becoming stouter toward club which is conical (pi. 2, fig. 7). 



Pronotum closely punctate, as wide in front as behind, with tw^o 

 transverse carinae parallel to its carinate hind margin, the posterior 

 carina almost complete, the anterior short, obsolete laterally ; mesono- 

 tum transversely rugosely punctate ; mesosternum mostly smooth and 

 polished; scutellum broadly rounded behind; foveae of metanotum 

 parallel ridged with hind margin broadly polished, median area of 

 metanotum punctate, slightly projected, its apex depressed toward 

 middle ; propodeum about twice as wide as metanotum, median carina 

 thin, slightly arched, lateral carinae converging behind, spiracular 

 area pubescent. Hind coxa without a distinct spur on upper margin, 

 punctate without, mostly polished within; hind femur (pi. 2, fig. 13) 

 triangular in shape twice as long as wide, outer surface punctate, 

 inner smooth and polished, its lower margin angled midway with 

 apical half very minutely toothed (more than 25 teeth). Wings 

 transparent, veins brown; front wings clouded along postmarginal 

 and at apex. 



Abdomen pear-shaped, about as long as thorax, its second tergite 

 narrow giving a petiolate appearance, tergites three to five short, con- 

 stricted and fused in median line, the remaining tergites swollen 

 and globular in form, the sixth tergite being much the largest and 

 comprising nearly all of the globular portion. A narrow polished 

 median line extends from the triangular depression at base of abdo- 

 men backward to nearly the middle of sixth tergite; hypopygium 

 short only about one-half length of abdomen. Ovipositor short and 

 spur-like, longer than abdomen, but not reaching dorsum ; its groove 

 just reaches around apex of abdomen. (Abdomen in dorsal and side 

 view shoAvn on pi. 3, fig. 20.) 



Male.— Length 5.5 mm. (head missing). Like female in structure 

 and coloration except in following respects: smaller size; abdomen 

 more elongate and more flattened on ventral surface ; constricted por- 

 tion longer; rufous color covers second tergite and extends laterally 

 on sixth; the front yellow transverse band on abdomen is farther 

 behind constricted region than in female, and there is a yellow median 

 spot on apex of abdomen.
