 and occiput, the strongh^ reticulate episterna and the markings 

 of the abdomen. 



Notoglossa incisura sp. nov. 



cf. Length 3.7.5 to .5 mm. Clypeus five-toothed; head strongly punctate 

 throughout; distance between the two posterior ocelli about three times the dis- 

 tance between one of them and the nearest eye-margin; pronotum margined 

 anteriorly; mesoscutum, mesoscutellum and episterna strongly punctate; 

 posterior portion of mesoscutum, mesoscutellum and metanotum with a 

 strong, longitudinal carina; squamae with a lateral point reaching beyond the 

 tip; metanotal spine about as long as the mesoscutellum, sides almost parallel, 

 not narrowed at the base; spine about twice as long as wide, deeply, widely, 

 and roundly emarginate; upper surface of propodeum obUquely striate, retic- 

 ulate beneath the spine; posterior face of propodeum except median area 

 which is triangular and finely rugose within, transversely striato-punctate; 

 sides of propodeum transversely striato-punctate; abdomen strongly punctate. 

 Color black; mandibles except the tips, small lateral spots on abdominal 

 tergites one and two, front and intermediate tibiae in front, posterior tibiae 

 at the base, anterior tarsi, intermediate and posterior tarsi basally, all yellow-

 and Monroe Canyon, Sioux County, Nebraska, on August 4 and

This species is quite distinct in the form of the squamae, the 

 metanotal spine and the sculpture of the propodeum as given in

 strongly punctured; posterior portion of the mesoscutum, the mesoscutellum 

 and the metanotum with a strong, longitudinal, median carina; squamae

 exceeding the tips of the latter; metanotal spine about as long as the meso- 

 scutellum, rather narrow, the dorsal surface strongly fluted, widely and
