25. (9) Encyrtus cecidomyie, n. sp. 
Female.—Length, 1.8™™; expanse 3.84™™; oreatest width of fore wing, 0.72™™, 
Comes closer, perhaps, to the European J. notodonte of Mayr than to any other spe- 
cies. The scape is nearly cylindrical; pedicel somewhat bulbous; funicle joints very 
gradually decreasing in length and increasing in width from joint 1, whichis one and 
one-half times as long as thick, to 6, which is nearly as thick as long; the club is oval, 
much compressed, and as long as the three preceding funicle joints together. Head 
and notum very delicately and uniformly punctured, the punctation of the mesos- 
cutum and scutellum identical. General color metallic-green, flagellum of the an- 
tennee black, all tarsi brown, femero-tibial articulation of front and middle legs, and 
distal tip of middle tibiz and accompanying spur honey-yellow. Marginal vein 
wanting, stigmal a trifle longer than postmarginal. 
Male.—Dimensions, punctation and coloration nearly the same as with 9. Differsin 
the antenne, the scape of whichis very short and slightly emarginate beneath ; pedicel 
short, less than half the length of first funicle joint; funicle joints subequal in 
length, subovoid in shape, well separated, and clothed with moderately long hairs ; 
club oval, as long as last two funicle joints together; club and funicle honey-yel- 
low, scape and pedicel black. 
Described from many ¢ and ? specimens bred, April 12, 1884, from 
the galls of Cecidomyia salicis-siliqua Walsh, collected in Northern Vir- 
ginia. [Dept. Agr. and C. V. R. Coll.] 
Genus CHILONEURUS Westwood. 
Female.—Antenne given off near the border of the mouth, 11-jointed ; pedicel longer 
than the succeeding joint; the flagellum is cylindrical or somewhat flattened; club 
spindle-shaped or compressed. Vertex narrow; head and face not coarsely punctured. 
Mesothoracie scutum is covered with short, delicate, silver-white hairs, and the 
scutellum bears a tuft of long, black, stiff bristles. The ovipositor protrudes slightly. 
Marginal vein long; stigma and postmarginal very short. 
Male.—Differs from the female principally in the antenne; the pedicel is scarcely 
longer than thick; the succeeding joints to the club are long, slender, distinct, and, 
with the exception of the first, are each contracted in the middle, and are furnished 
above with two half whorls of long, diverging hairs; the club is not thicker than the 
preceding joint, and is shorter than the two preceding joints together. The hairs 
upon the seutellum are more scattered than in the ¢, and not gathered together in a 
tuft. 
26. (1) Chiloneurus albicornis Howard. 
A single female of this species was bred, May 7, 1883, from an unde- 
termined species of Lecanium collected on Quercus aquatica, ‘ water- 
oak,” at Biuffton, S. C., by Dr. J. H. Mellichamp. [C. V. R. Coll.] 
In a small collection of chalcids labeled by Walker I find a Chilon 
eurus bearing the label C. elegans Dalm., which closely resembles C. al” 
bicornis, the only difference perceptible (perhaps on account of the poor 
condition of the specimen) being a darkening of the third and fourth 
funicle joints. The Walker specimen, however, differs radically from 
the description of elegans in Mayr’s revision, and furnishes only another 
instance of the proverbial carelessness of the English author.
