404 NEW SPECIES OF HYMENOPTERA 



mesoscutuni at the apex, a narrow median line on the mesoscutum, narrow 

 basal margins of the episterna, wide line above the intermediate coxae, en- 

 closed space of propodeum, and a small triangular spot at the apex of the 

 propodeum, black. First segment of abdomen coarctate; all the tergites and 

 sternites with deep, sparse punctures; last sternite terminating in a short 

 spine; first segment entirely rufous, second sternite rufous, second tergite 

 piceous, remaining segments black; fascia at the apex of the first tergite deeply 

 emarginate medially, wide fascia at the apex of the second tergite slightly 

 emarginate medially; fasciae at the apex of the third, fourth and fifth tergites, 

 a large spot on the last tergite, narrow fascia at the apex of the second sternite, 

 and small lateral spots on the third sternite, yellow. Legs rufous; spot at 

 the apex of anterior and intermediate femora, anterior and intermediate tibiae 

 below, and anterior tarsi, yellow. Wings hyaline, except a fuscous cloud 

 which covers the marginal, the second and third submarginal, and the first 

 discoidal cells; submedian cell longer than the median; cubitus of hind wings 

 interstitial with the transverse median nervure; stigma yellow. 

 9 . Unknown. 



Type, a male collected at Harrison, Nebraska, August 12, 1912, 

 (R. W. Dawson). One paratype, a male collected at Omaha, 

 Nebraska, July 14, 1914, on Chamaecrista fasciculata, (L. T. 

 Williams). The paratype differs from the type in having the 

 legs entirely rufous, no yellow line below the anterior ocellus 

 and in having the basal portion of the second abdominal tergite 

 more reddish than piceous. 



This species is allied to rufocinctiis, but may easily be distin- 

 guished by the general color being rufous, while that of the former 

 is black. 



Hypomellinus tricinctus sp. nov. 



9 . Length 13 to 14 mm. General color rufous; body covered with a fine, 

 subtle pile. Head rufous; eyes slightly converging towards the clypeus; 

 clypeus very convex, basally and laterally with sparse silvery pubescence, 

 basally with coarse punctures, margined at the apex; front, vertex and cheeks 

 with coarse, sparse punctures interspersed with very minute punctures; distance 

 between posterior ocelli slightly greater than the distance between them and 

 the nearest eye margin; antennae long, slender, reaching beyond the mesoscu- 

 tellum, entirely rufous. Thorax rufous, with large, deep punctures; propo- 

 deum rugose; suture between the mesoscutum and mesoscutellum foveolate; 

 episternum and epimeron of mesothorax separated; enclosed space of i)ropo- 

 deum distinct, channelled medially, with coarse, slightly oblicjue striae; wide 

 fascia on the mesoscutellum, and metanotum, yellow. First segment of abdo- 

 men coarctate, with large, deep punctures like those of the mesoscutum; re- 

 maining segments with finer, deep punctures; pygidium margined at the sides 

 with sparse shallow punctures; first and second segments rufous, remaining 

 segments black; pygidium reddish; narrow fascia at the apex of first tergite
