Arenetra leucottenia, n, sp. 



Closely related to rufipes, from which it differs in color and structure. 



Female. — Length, 10 mm. Head and thorax almost uniformly dull, closely 

 punctured, nearly rugoso-punctate, the punctures shallow and not sharply de- 

 fined ; antennaj forty-four jointed, scape and pedicellum together distinctly 

 longer than the third joint of the flagellum, but shorter than the first joint. 

 Dorsulum rather shining and with some well-separated punctures, hardly an 

 indication of parapsidal grooves present; mesopleura with a small, shining, 

 sparsely punctured space above the middle of the sclerite and at the posterior 

 border: carina separating metanotum from metapleura very faint, apparently no 

 carina between the spiracles and the metanotal metapleural carina, an indistinct 

 carina between the spiracles and the posterior carina of the metathorax; wings 

 almost exactly as in nigrita, the discocubital nervure not broken. Abdomen 

 with the first segment almost rugosopunctate, the second segment roughened, 

 the third dullish, the segments beyond polished. Pubescence typical. Black ; 

 femora at tip yellowish, libite brownish, tarsi of four anterior legs pale brownish, 

 the posterior tarsi dark brown ; second and third abdominal segments with a 

 narrow whitish apical and lateral margin, fifth, sixth and seventh segments 

 with an apical whitish margin which extends more or less to the sides; ovi- 

 positor and sheaths of about equal length, nearly as long as the first two ab- 

 dominal segments, ovipositor dark brown, sheaths black ; first fiv« ventral 

 segments brownish with a broad apical margin yellowish. 



Type: University of Kansas. Type locality : Douglas county, Kansas, March, 

 F. H. Snow. 



Nematopodius exclamans, n. sp. 



Related to N. (Mesostenus) gracilipes and longicaudus. 



Female. — Length, 13 mm.; ovipositor, 29 mm. Head shining; face rather 

 dullish, very closely punctured on the median elevated portion, sides of the face 

 along the edges polished, sparsely punctured; cheeks polished, apparently im- 

 punctate; clypeus distinctly bulged, apparently more coarsely punctured than 

 the raised portion of the face : labrum sparsely and rather indistinctly pitted, 

 deeply emarginate on the anterior margin ; mandibles rather sparsely, coarsely 

 punctured, some of the punctures confluent; malar space not much higher than 

 the flagellum is wide at base; antenna? thirty-four jointed, the scape and pedicel- 

 lum together as long or nearly as the fourth joint of the flagellum; an elongated 

 low tubercle between the antenna?. Thorax shining; dorsulum with distinct 

 parapsidal grooves that terminate in or near the middle of the posterior half, the 

 middle lobe with rather sparse punctures, the lateral lobes with the punctures 

 close together, but to a great extent well separated, some nearly adjoining; 

 scutellum polished, rather sparsely punctured; metanotum rugulose, dullish, 

 except the basal lateral area which is to a great extent polished and sparsely 

 punctured, the outer portion shining and closely punctured, metanotum rather 

 distinctly areolated, basal area small, nearly quadrate, areola pentagonal, lateral 

 sides equal or nearly, basal side less than one-half the length of the apical side; 

 petiolarea not distinctly defined, broad, angled below the middle, and occupying 

 the greater part of the metathorax; metapleura rugulose, punctate and closely 

 so, dullish ; mesopleura sculptured nearly like the lateral lobes of the dorsulum ; 

 mesopleura separated from the mesosternum by a distinct, narrow, crenate, 

 undulate groove the mesosternum with a longitudinal, crenate, medial groove 

 that is about as narrow but not so deep as the pleurosternal groove; wings 

 strongly brownish, stigma and nervures dark brown, the stigma pale at base;
