 tophyes Konow (Xyelinae).

Odontophyes ferruginea n. sp. 



°. 11.5 mm. Length of wing, 12 mm. Dull ferruginous, the follow- 

 ing parts more or less infuscated : eyes, indefinite spot over ocelli, 

 a pair of lateral indefinite spots in front of this, anterior lobe of meso- 

 notum, lateral lobes along the sutures and behind, the lateral spot 

 extending over upon the sides of the scutellum, metanotum, basal 

 plate, two large spots upon second dorsal abdominal segment, the five 

 succeeding dorsal segments excepting their lateral and posterior margins, 

 the latter being extended forward with each side into a light spot nearly 

 enclosed by the dark color. 



These parts yellowish : basal joint, antennae and the nine small ter- 

 minal joints, clypeus and face above to insertion of antennas, anterior and 

 posterior orbits, labrum, mandibles except apex, the other mouth parts, 

 tegulae, summits of coxae, trochanters, anterior and middle femora and 

 tibiae in front, base and extreme apex of hind femora, basal half of hind 

 tibiae, hind tibiae and the venter of the abdomen. 



Wings yellowish hyaline, the nervures and stigma brown. 



The markings of the thorax and posterior regions of the head are in- 

 definite and the colors run into each other. The bands upon the pos- 

 terior legs are particularly distinct. 



Described from one 9 specimen in the author's collection 

 taken by him at Baldwin, Kansas, in April, upon the flowers of 

 the early shrub willow. 



This species agrees perfectly with Konow' s characterization 

 of the genus. From the only species hitherto known O. avi- 

 ingrata Dyar, the ferruginous ground color sufficiently dis- 

 tinguishes it, Dr. Dyar's species being described as steel 

 blue. Odontophyes avii?igrata was described in Psyche 8:213, 

 1898, as a species of Pleuroneitra and the genus was erected by 

 Konow (Wien. Ent. Zeit. 18:41, 1899) for its reception. Our 

 species must resemble rather closely Megaxyela major Cresson, 

 but differs by the generic characters. The genera Megaxyela, 

 Odontophyes and Pleuroneura are very closely related and care- 

 ful collecting may reveal intermediates.
