versity of Kansas. The male can be distinguished from the male of 

 U-scripta Fox, by the character of the genital stipes as shown in 

 the figures and by the fact that TJ-scripta has the mesosternum and 

 the second and third ventral abdominal segments completely yellow 

 and yellow fasciae on the fifth and sixth. The mesosternum of 

 arcuata is marked with black, sternites two and three have only 

 lateral spots and five and six are entirely black. The female of 

 U-scripta has the mesosternum wholly yellow, lateral spots on stern- 

 ites 2-5, and the apex of six marked with yellow; the female of 

 arcuata has the mesosternum marked with black and the yellow on 

 the sternites confined to small lateral spots on 2-4.

Male. — Black: Labrum, mandibles except apices, clypeus, scape, 

 flagellum below, frons except pair of triangular black spots below 

 anterior ocellus, and pair of widely separated points at base of clyp- 

 eus, broad posterior orbits united across vertex, prothorax entirely, 

 tegulae, broad lateral lines and broad U-shaped discal mark on 

 scutum, broad fascia on scutellum, fascia on metanotum, dorsum 

 and posterior surface of median segment except black band adjacent 

 to postscutellum and narrow border of oblique sutures, sides of 

 median segment, metaplem'ae and mesopleurae entirely, mesoster- 

 num, broad fasciae on tergites 1-5, each with a pair of emargina- 

 tions and a medial notch on anterior border, the emarginations on 

 second and third deepest, three spots on sixth tergite, apex of sev- 

 enth, sternites 1-3 almost entirely, broad fascia on fourth with medial 

 emargination on anterior border, narrow broken fascia on fifth, 

 broader one on sixth, apex of seventh, legs except narrow stripes on 

 posterior surface of anterior and posterior femora, yellow. 



The scape is very short and broad and segments 5-11 of the 

 flagellum are slightly spinose on the posterior sm^face, 8-11 most 

 evidentl}^ so. The apical segment is curved, conical in outline and 

 almost as long as the two segments immediately preceding it. The 

 middle femora are dentate. The middle tibiae are slightly carinate 

 on the inner surface and the anterior margin at the apex is drawn 

 out into a process that bears a short spine at its tip. The middle 

 metatarsi are strongly curved on the inner side and basally bear fom' 

 spines. The second and sixth sternites are without processes of any 

 kind, but the seventh bears a pair of carinae that diverge basally. 

 Tlio eighth ends in a single spine.
