76 PSYCHE [August 
take pleasure in announcing the discovery in the State of Illinois of four encyrtine 
and aphelinine parasites new to this host and of the specific determination of one 
other, recorded by Gahan (1907) in Maryland. ‘Three of these parasites proved to 
be new to science and are described in following. ‘The other two are Coccophagus 
lecanii (Fitch) and Coccophagus longifasciatus Howard. ‘The former is a common 
coccid parasite in the United States, attacking no less than eight or nine hosts; 
the latter was described in 1907 from Ceylonese specimens reared from (Lecanzum) 
Saissetia nigra (Nietner) just ten years previously. 
The parasites are described or listed in order of their systematic arrangement. 
Family ENCYRTIDAE. 
Subfamily ENcYRTINAE. 
Tribe Ectromini. 
1. Anagyrus nubilipennis species nova. 
Normal position. 
Female: — Length, 1.9 mm. Moderately large for the tribe. 
General Color shining black, with a metallic sheen; intermediate and posterior 
tarsi fuscous; anterior tarsi dusky; ventral aspect of scape fuscous. Wings normal, 
the oblique hairless line running from stigmal vein, proximo-ventrad to the posterior 
margin present and joined near that margin by another longer hairless line pointing 
distad, both together forming a broad “‘Y” 
cephalad into the wing; discal cilia moderately dense and uniform; marginal cilia 
short and close; an infuscation, rectangular in shape, extends transversely across 
the wing from the stigmal, marginal, and distal fourth of the submarginal veins to 
the posterior margin and includes most of the two hairless lines; the distal (or lateral) 
marking whose mouth opens disto- 
margin of this infuscation is somewhat convex; remainder of the wing hyaline; 
venation dusky or brownish black; marginal vein short and broad, darker, slightly 
longer and broader than the postmarginal vein but equal to the stigmal vein in length. 
Hind wings hyaline, discal cilia close, with a short curved hairless line at basal third, 
originating at the postmarginal vein. 
Antennae clavate, the funicle cylindrical, inserted near the clypeal border. 
Scape long and slender, nearly reaching the vertex, nearly as long as the pedicel and 
first two funicle joints combined, very slightly compressed or dilated distad; pedicel 
obconic, over one-third shorter than funicle joint 1, the latter cylindrical and slightly 
longer than the next joint; funicle joint 2 broader; funicle joint 3 subequal to
