38 PEOCEEDINGS OF THE NATIONAL MUSEUM vol.80 



Head yellow; vertex and occiput brownish; antennae brown or 

 brownish yellow, the basal flagellar segments usually more or less 

 blackish; thorax yellow, the mesonotal lobes more or less fuscous or 

 blackish ; metanotum and propodeum blackish ; legs entirely yellow ; 

 wings hyaline ; stigma yellow with a large brownish cloud, or brown, 

 broadly pale at base; abdomen yellow, with first tergite black, the 

 second blackish on basal half, the third more or less infuscated 

 medially, the following mostly yellowish. 



Male. — Similar to the female, except that the scape is rather con- 

 spicuously thickened; antennae of allotype 49-segmented ; abdomen 

 more completely blackish above than in the type, and antennae 

 darker. 



ry^e.— U.S.N.M. No. 43506. 



Type locality. — Kanawha Station, W. Va. 



Host. — Laspeyresia caryana Fitch. 



Remarks. — Described from six female and five male specimens 

 reared September 7, 1906, by Dr. A. D. Hopkins, at the type locality, 

 and one female and three males reared at Richmond, Ohio, by A. A. 

 Girault. 



In addition to the type series, the national collection contains 

 specimens reared from Laspeyresia molesta Busck at Moorestown, 

 N. J. ; from Carpocapsa pomonella Linnaeus in Virginia, Ohio, and 

 Arkansas; from Acr^hasis species in Texas; from Rhyacionia 

 rigidana Fernald at Valparaiso, Fla. ; and from Laspeyresia caryana 

 at A. and M. College, Miss. There is considerable variation in 

 color, both in the type series and in the additional specimens just 

 mentioned, but nearly always the mesonotal lobes, the metanotum, the 

 propodeum, and the three basal abdominal tergites are at least some- 

 what infuscated; the stigma rarely is entirely yellowish without a 

 distinct cloud. 



25. MACROCENTRUS MELLIPES Provancher 



Macrocentrus mellipes Peovancher, Nat. Can., vol, 12, p. 172, fig. 19, 1880. 



Type. — In the Museum of Public Instruction, Quebec, Canada. 



This species, the type of which I have not seen, has been placed in 

 the key on the basis of the original description and supplemental 

 notes made by S. A. Rohwer on an examination of the type in 1915. 

 The United States National Museum contains a single female speci- 

 men from Montana, which appears to agree with mellipes in struc- 

 ture, sculpture, and color, and although it is somewhat smaller than 

 the type I believe it to be that species. Evidently Tnellipes is very 

 similar to aegeriae but can be separated by the characters given in 

 the key.
