Olesicampa melanerythrogaetra, n. sp. 



Apparently closely related to L. (Olesicampa?) brachyura, of which it may 

 prove to be the male. 



Male. — Length, 7 mm. Head minutely roughened and indistinctly punc- 

 tured; cheekB dullish ; face dull, rather densely covered with pubescence that is 

 tinted with golden brown; antennte thirty-nine jointed or forty jointed, scape 

 and pedicellum together a little shorter than the first joint of the flagellum. 

 Thorax almost uniformly dull, finely sculptured; doreulum with the faintest im- 

 pressions to indicate where the parapsidal grooves would be impressed, area more 

 densely sculptured and duller than the adjoining area; mesopleura with an al- 

 most triangular, smooth, shining, impressed area occupying the region above the 

 oblique impression or groove, the area beneath closely, rather distinctly punc- 

 tured, the surface between the punctures minutely roughened; metathorax 

 distinctly areolated, the ridges separating the areas very distinct, areola and petio- 

 larea confluent, basal area very narrow, about twice as long as wide at base, 

 forming an acute-angled triangle, areola more than twice as long as its greatest 

 width, the lateral ridges of the areola angled at the basal third, basal third of 

 the areola wrinkled beyond, the surface is roughened, petiolarea angled a little 

 above the middle, roughened and with rather coarse transverse strite, lateral 

 areas sculptured somewhat like the dorsulum except the apical lateral area 

 which is rugose; metapleura rather rugosopunctate, very closely sculptured; 

 wings pale brownish, stigma and nervures rather brownish testaceous with a 

 blackish tinge, first abcissa of the radius a little more than two- thirds the length 

 of the second abcissa, areolet quadrangular, petiolate, the petiole as short as the 

 shortest side of the areolet, first abcissa of the cubitus beyond the first transverse 

 cubitus about as long as the second transverse cubitus between the petiole and 

 the cubitus, the first tratsverse cubitus between the petiole and the cubitus 

 shorter than either of the last two sides, of the areolet mentioned, being next 

 in size to the shortest side, discocubital nervure with a trace of a stump a 

 little before the middle, transverse median nervure received a little beyond the 

 basal nervure, second abcissa of the discoidal nervure nearly two- thirds the length 

 of the recurrent nervure. Abdomen somewhat dullish, minutely, rather subtly 

 sculptured; petiole nearly smooth, with no distinct elevated line extending from 

 the spiracles to the posterior margin. Almost uniformly pubescent, the pubes- 

 cence to a great extent of the same color as that on the face, but shorter and not 

 so conspicuous; the smooth area of mesopleura, most of the lateral areas of the 

 metathorax and the areola and petiolarea appearing bare. Black; scape and 

 pedicellum ochreous beneath, brownish above; mandibles, tegular and base of 

 wings yellow, mandibles tipped with brown which shades from pale to dark, al- 

 most black; palpi rather ochreous; legs testaceous, the posterior pair somewhat 

 ferruginous, claws, apical tarsal joint of anterior legs, tarsal joints of middle legs 

 posteriorly, posterior tibite above and tarsi all brownish; abdomen with a rufous 

 band at apex of petiole, the remainder of the abdomen rufous, except the margins 

 of the second segment, a broad apical margin of the third, a narrow apical mar- 

 gin on the fifth, the sixth dorsally and a large portion of the seventh which are 



black. 



Type: University of Kansas. Type locality : Clark county, Kansas, 1962 feet.

Female. — Similar to the male ; petiole of areolet shorter, as long as the short- 

 est side of the areolet or a little shorter ; exserted portion of the ovipositor a little 

 longer than the abdomen, sheaths about three-fourths the length of the abdomen ; 

 abdomen rufous, a narrow black band at apex of petiole, basal two- thirds of peti-
