NO. 193». DESCRIPTIONS OF NEW SAWFLIES—ROHWER. 221 



Nebraska, female, April 27, 1902, collected by L. Bruner. Pennsyl- 

 vania, female from C. F. Baker collection. 

 Type.—Csit. No. 14260, U.S.N.M. 



MACROPBnrA TENUICORNIS, new species. 



In Enslin's revision of the Palaearctic MacropJiya this species runs 

 to annulicornis Konow, but has the clypeus and labrum yellow and 

 the antennae long, so it can not be confused with that species. From 

 other species it is quite distinct. 



Female. — Length 10.5 mm. Labrum truncate; clypeus shallowly, 

 broadly, squarely emarginate, lobes narrow rounded apically; supra- 

 clypeal area flat, becoming somewhat convex between the antennae; 

 antennal furrows shallow, complete; middle fovea elongate; ocelloc- 

 cipital line one-third longer than the postocellar line; ocellocular line 

 four times as long as the postocellar line ; postocellar furrow obsolete ; 

 postocellar area slightly wider posteriorly, the anterior width about 

 one- third greater than the length; front sunken, so the cephal- 

 caudad diameter of the head at the antennae is not as great as at the 

 orbit; antennae 6.5 mm. long, slender, the third joint nearly as long 

 as the fourth and fifth; thorax closely, distinctly punctured; stigma 

 slightly narrowing apically, apex truncate; third cubital cell shorter 

 on the radius than the second; sheath narrow, straight above, 

 rounded apically, more strongly so below. Black; clypeus, labrum, 

 mandibles, fourth and fiith antennal joints above, angles of the pro- 

 notum, tegulse, spot on the scutellum, line on metascutum, two large 

 spots on propodeum, four anterior legs except the tips of the femora 

 and tibiae; spot on the posterior coxae exteriorly, basal two-tJiirds 

 of posterior femora, basal two-thirds of posterior tabiae exteriorly, 

 posterior tarsi, except apices, yellow or yellowish. Wings dusky 

 hyaline, venation black. 



Lebong, India. One female collected at 5,000 feet, September, 

 1908.

ZAMACROPHYA, new genus. 



Habitus and head of Macrophya, but the metepimeron is small, 

 as in Tenthredo, etc. From Labidia, to which it is more closely allied, 

 it may be separated by the entire absence of dilations above the 

 antennal sockets, and feebly defined antennal foveae, the front being 

 flat as in Macrophya. 



Belongs to the tribe Tenthredinini. Clypeus deeply emarginate, 



malar space very narrow; nasal margins of the eyes strongly converg- 



! ing to the clypeus ; space between the eyes at the antennae less than 



I the length of the eye; antennal foveae very small; no ridges from the 



nasal margins of antennae, front flat as in Macrophya; occiput car-
