it runs diagonally and downward to antennal fossa; wings hyaline; 

 abdomen finely punctured above. 



Habitat. — St. Clair, Trinidad. 



Described from 7 specimens reared August, 1912, from unknown 

 eggs by Mr. F. W. Urich. 



Type.— C&t. No. 16037, U.S.N.M. 



This species greatly resembles N. jiavipes Ashmead, but in that 

 species the inner orbits are httle or not at all convergent; the diagonal 

 carina running from carina along inner orbit to antennal f ossal touches 

 the latter almost at base and is continued below base. 



The species is named in honor of Dr. W. H, Ashmead, who described 

 not only this genus, but also many others in his generic revision of the 

 Chalcidoidea. 



Family PERILAMPID^. 



PERILAMPIDEA, ne^^ genus. 



Antennae 13 jointed with 2 ring joints, the pedicel shorter than the 

 first joint of funicle; eyes distinctly hairy; mandibles 3-toothed; 

 thorax above coarsely umbilicately rugoso-punctate; parapsidal fur- 

 rows indicated only by an indistinct depression of the surface ante- 

 riorly; axillae widely separated; stigmal vein about two-thirds as 

 long as the marginal; postmarginal longer than the marginal; hind 

 tibiae with 2 apical spurs; abdomen compressed. 



This genus resembles Perilampus in the thorax, but the antennae 

 have 2 ring joints, the eyes are conspicuously hairy, the stigmal and 

 postmarginal vems are long and the abdomen is compressed. 



Type. — Perilampidea syrplii Crawford. 



PERILAMPIDEA SYRPHI, new species. 



Female. — Length about 2.25 mm. Head and thorax very dark 

 blue, back of head and cUsk of mesoscutum bronzy; scape and pedicel 

 testaceous, rest of antennae brown; face rather finely reticulated by 

 carinae, along upper inner orbits becoming umbiUcate ; thoracic notum 

 except extreme sides of scutum and axillae with coarse irregular 

 reticulate umbihcate punctures; parapsidal furrows indicated ante- 

 riorly only by a shght depression of the integument, otherwise obso- 

 lete; under side of projecting apical portion of scuteUum more finely 

 reticulated; wings hyahne, veins light brown; coxae brown with 

 purple reflections; femora brown, their apices and the rest of the 

 legs whitish; abdomen brown. 



Habitat. — Moruga, Trinidad. 



Described from 3 specimens reared by F. W. Urich, in May, 1912, 

 from the larva of a syrphid preying on Dactylopius citri found on 

 cacao. 



Type.— Csit. No. 16038, U.S.N.M.
