middle fovea deep, elongate, with sloping walls, not extending to 

 the anterior ocellus; head subopaque; front and face with close 

 punctures; vertex with the punctures slightly more separated than 

 those on the front: posterior orbits with widely scattered punctures; 

 postocellar area sharply defined, not arched, twice as wide as the 

 median length: antennae 19-jointed; the median rami subequal in 

 length with the length of the joints; and nearly uniform in width; 

 third joint distinctly longer on the dorsal margin than the fourth; 

 prescutum and scutum with close, well-defined punctures; scutellum 

 wider than long, obtusely angled posteriorly, the surface with uni- 

 form well-defined punctures; mesepisternum with the punctures so 

 close as to appear granular; tergites shining, highly polished; nates 

 shining, when highly magnified the surface is reticulate and there 

 are scattered, setigerous punctures; sheath when seen from below 

 truncate apieally, the pad-like plates three times as long as wide 

 and well removed from the median ridge ; last sternite with a broad, 

 shallow, median emargination; tarsal claws with a small erect tooth 

 at the middle; hind tarsi rather short; the basitarsis only a trifle 

 longer than its apical width; the longer calcarium of the posterior 

 tibiae only a trifle shorter than the hind basitarsus. .Black; head 

 ferruginous except the antennal furrows to the ocelli and a band 

 between the ocelli which are black; pronotum, scutellum, the upper 

 part of the mesepisternum, sides of the tergites, whitish; sternites 

 medianly and nates ferruginous; legs rufo-ferruginous with apices 

 of the anterior femora and the bases of all the tibiae and the base 

 of the hind basitarsi whitish; wings hyaline, venation dark brown, 

 stigma clear in the middle. 



Type locality. — Tomahawk Lake, Wisconsin. 



Described from one female reared from larvae collected on Pinus 

 resinosa by S. A. Rohwer and recorded under Bureau of Entomology, 

 No. Hopk. U. S. 10170. 



Type.— Cat. No. 21775, U.S.N.M. 



NEODIPRION (NEODIPRION) EXCITANS, new species. 



Allied to pinus-rigidae (Norton), but may be distinguished in the 

 female by the longer rami on the antennae, the more sparsely punc- 

 tured head and mesepisternum, serrate upper apical margin of 

 lance, teeth on basal rib of lancet, and only having thirteen teeth 

 (the medium ones being larger) on seventh (from apex) rib of lancet. 



Female. — Length, 8 mm. Anterior margin clypeus depressed, 

 broadly arcuately emarginate; head shining with distinct separate 

 punctures; middle fovea broad shallow; postocellar line distinctly 

 longer than ocellocular line; median cephalo-caudad length of post- 

 ocellar area fully half as great as the anterior width of postocellar 

 area; postocellar area very slightly convex; antennae 16-jointed, 

 third joint distinctly longer than the fourth, fourth, fifth and sixth
