CHALCIS NEPTIS, new species 



FiGUEES 8, c; 11, &; 14, c 



This species is closely related to Chalcis divisa (Walker) but is 

 distinguished by the long, narrow body, the longitudinal mesal de- 

 pression of the mesopraescutum, and the conspicuously rugose petiole. 



Description. — Black; two yellow spots on frons near bases of an- 

 tennae; anterior and mesolegs brown, with apices of femora and 

 tibiae yellow; wings brown; metafemora brown, usually with base, 

 an oblique dorsal stripe, and a small ventral spot near apex, yellow. 



Female: 5-6 mm. Antennae inserted slightly ventrad of center 

 of frons; apex of scape just attaining level of posterior ocelli, ring 

 segment one-half length of pedicel ; segment 4 one and one-half times 

 the length of segment 5, segments 5 and 6 equal, following ones 

 slightly shorter and equal in length, suture between 12 and 13 ob- 

 scure; interantennal projection large, terminating in a carina run- 

 ning halfway up scrobe cavity ; width of malar space one-half height 

 of compound eye ; f rontogenal suture extending ventrally from com- 

 pound eye for two-thirds its length, then abruptly recurved toward 

 mandible; a carina extends parallel to suture near mandible, then 

 curves obliquely ventrally at point where suture curves: suture and 

 carina enclose a small triangular area at ventral margin of compound 

 eye ; left mandible with one large, blunt, dorsal tooth and a smaller, 

 rounded, ventral tooth, right mandible with one sharp dorsal tooth 

 and two blunt ventral ones, ventral teeth slightly curved inward; 

 diameter of posterior ocellus one-third width of interocellar space.
