the base of clypeus equal to about one-fourth the distance between 

 the inner eye margins at antennae ; face below antennae a little more 

 strongly sculptured than the posterior orbits, with a nearly quad- 

 rate slightly elevated area in the middle ; f rons coarsely transversely 

 striated with a distinct carina about midway between the anterior 

 ocellus and the base of antennae, this carina angulated on each side 

 of the median line so as to form a low upward projecting tooth on 

 each side of the median line and about midway between it and the 

 eye-margin, the lateral extension of the carina terminates at a small 

 low spiracle-like tubercle near the eye margin; notauli impressed 

 on the anterior one-third of the mesoscutum ; sternauli distinctly 

 impressed from the anterior margin to the middle of mesopleura; 

 propodeum distinctly completely areolated, the carinae fine, areola 

 one and one-half times as long as broad, rounded anteriorly, the 

 carina between areola and petiolarea weak; petiolarea slightly de- 

 pressed; venation normal, the areolet slightly narrowed anteriorly; 

 femora very slightly swollen; abdomen about twice as long as the 

 thorax, slender; postpetiole reticulately rugulose, evenly convex, 

 without dorsal carinae; second tergite with the gastrocoeli obsolete; 

 ovipositor sheaths extending beyond the apex of abdomen about the 

 length of sixth tergite. Entirely ferruginous except the eyes, apex 

 of mandibles, apical joint of all tarsi, and the apex of abdomen 

 beyond the fourth tergite, which are black ; wings hyaline, the veins 

 and stigma black, the latter with a yellowish spot at inner angle; 

 antennae ferruginous, the apex slightly darker. 



Male. — Antennae 22-jointed in the allotype; anterior margin of 

 the clypeus more disitinctly convex than in the female; a line from 

 antennal fossae to base of clypeus equal to approximately one-third 

 the distance between the eyes at antennae; frons transversely striated 

 but without the transverse carina and without toothlike projections; 

 apex of fifth tergite and all tergites beyond black. 



Type-locality. — Washington, District of Columbia. 



Type.— Cat. No. 21614, U.S.N.M. 



Host. — Laspeyresia molesta Busck. 



Six females and two males reared by Mr. E. E. Selkregg from 

 pupae of the above-named host and recorded in the Bureau of Ento-

EXETASTES SUAVEOLENS Walsh. 



Campoplex niger Peovancher, Niit. Can., vol. 11, 1879, p. 148. 

 Exetastes provancheri Dalla Toree, Cat. Hym., vol. 3, 1902, p. 73. 



A specimen compared by the writer with Provancher's type and 

 made a homotype is identical with a homotype of Walsh's species in 

 the collection of the United States National Museum compared by 

 Mr. H. L. Viereck.
