Remarl'fi. — Described from three females. The holotype >Yas 

 reared in 1931 at the Oriental Fruit Moth Laboratory, Moorestown, 

 N. J., from the cocoon of a Macrocentrvs infesting Gmpholitha 

 moUsta (Busck) and recorded as specimen No. 564. A second female, 

 reared at the same laboratory in 1933 as specimen 1504, apparently 

 emerged from a pupa of G. molest a taken at Berlin, ]\Id. One female 

 was reared by H. S. McConnell, of the iMaryland Agricultu.ral Ex- 

 periment Station, from a cocoon of Mdcrocentrus infesting G. molesta 

 taken at Salisbury, Md., in 1929. 



5. ARACHNOPHAGA AUREICORPUS (Girault) 



Anastatus aureicorpus GlRAtrLT, Ann. Ent Soc. Amer., vol. 9, p. 299, 191G. 



In color this species is almost exactly like nocua and can be dis- 

 tinguished only by its much larger size, by the more numerous bristles 

 on tlie scutellum (approximately 50) , and by the fact that the posterior 

 ocelli are placed distinctly more than the diameter of an ocellus in 

 front of the sharp angle formed by vertex with occiput. Also ex- 

 tremely similar to costalis, from which it differs mainly in that the 

 heavily infuscated medial area of fore wing is yellowish (golden in 

 some lights) instead of blackish; the head, thorax, abdomen, and 

 legs are mostly pale yellow with only the prescutum, concave posterior 

 portion of mesoscutum, middle of mesosternum, and to some extent 

 the vertex and f rons blackish with slight metallic reflections. In the 

 type the scutellum is entirely yellow, but in two specimens from South 

 Carolina it is weakly tinged with metallic apically. 



Described by Girault from one female specimen reared by Carl 

 Hartman, at Austin, Tex., from what Girault said appeared to be a 

 syrphid puparium. The alleged puparium, however, is a lepidopter- 

 ous pupa and, according to Carl Heinrich, is that of some species of 

 Lycaenidae. Besides the type, the national collection contains two 

 females from Greer, S. C, taken September 18, 1930, by J. O. Rowell. 



6. ARACHNOPHAGA NOCUA, new species 



Female. — Length 2.75 mm. Color yellowish testaceous, only the 

 ocellar triangle, medioposterior depressed portion of mesoscutum, and 

 middle of mesostermnn dark brownish or blackish ; antennal flagellum 

 and scape brownish testaceous, and club blackish; forewing hyaline 

 from base to beginning of curve in submarginal vein, strongly fuscous 

 from there to apex of stigmal vein, and subhyaline at apex with an 

 irregular transverse band just distad of stigmal vein slightly paler, 

 the coloration of different areas due to differently colored cilia, those 

 on infuscated median portion giving to that area a distinctly yellow- 

 ish tinge in some lights while on the obscure, transverse, pale band
