ART. 6. STUDIES ON LEUCOSPIDINAE C. J. WELD. 31 



hind margin which covers the posterior transverse carina ; small 

 spots above tegulae; a transverse band near hind margin of scutel- 

 lum ; a small spot on middle of metanotum ; two narrow transverse 

 bands on abdomen, one on constricted portion (third, fourth, and 

 fifth tergites) and the other near posterior margin of sixth tergite; 

 small spot on metapleura below hind wing ; a streak on dorsal margin 

 of hind coxa; spot at base and band along upper margin of hind 

 femur; upper margin of hind tibia and all of tarsal joints; whole 

 of first and second legs except coxae. 



Head as broad as pronotum ; vertex flat, broad, densely punctate ; 

 irons narrowest opposite insertion of antennae ; face silvery pubes- 

 cent; line from median ocellus to lower edge of clypeus 1.1 times 

 interocular distance ; antennocular space less than interantennal ; 

 malar space one-sixth length of eye; scrobes deep, converging above, 

 margin carinate, cavities striate ; triangular spur between scapes has 

 polished median carina; eyes slightly emarginate; postocellar space 

 1.0 times ocellocular; occipital carina weakly angulate forward; 

 antennae gone except first three segments of one; scape cylindrical 

 more than twice as long as wide. Pronotum has two transverse 

 carinae in front of its hind margin, the posterior prominent and 

 almost complete, the anterior much weaker, extends only short dis- 

 tance on either side median line; mesoscutum slightly longer than 

 pronotum, coarsely rugoso-punctate ; scutellum broadly rounded be- 

 hind; lateral foveae of metanotum setigerous punctate, with smooth 

 l^olished hind margins; apex projecting, strongly depressed at mar- 

 gin ; propodeum twice as wide as metanotum, rugosely punctate, with 

 arched median keel and strong lateral carinae; spiracular area 

 covered with long whitish hairs. Hind coxae finely punctate without 

 a spur on upper margin ; hind femora a little over twice as long as 

 wide, with broad blunt basal tooth on lower edge followed by twelve 

 small teeth of which the third, fourth, and fifth are largest; hind 

 tibiae arcuate with two distinct spurs at apex ; fore wings subhyaline, 

 darker along front margin and with large fuscous spot near apex; 

 hind wings nearly transparent. 



Abdomen seen from above constricted in front of middle, swollen 

 behind constriction and compressed toward apex; seen from side 

 the dorsal line is wavy, with elevations in second and sixth seg- 

 ments and with posterior half of abdomen strongly depressed. Sec- 

 ond tergite longer than broad, about half the length of sixth, not 

 carinate medianly but with a smooth shining line which broadens 

 toward its hind margin. Ovipositor reaches three- fourths the dis- 

 tance to base of sixth tergite, its groove deeply cut and V-shaped 

 at tip.
