20 EDWARD P. VAN DUZEE. 



two joints thickeiif^d, black. Proiiotum transverse, anterior and posterior margins 

 straight and parallel, sides depressed with margins ratlier broadly flattened, tlie 

 edge narrowly recurved and slightly arcuated, fringed witli stiff hairs; antei'ior 

 angles rounded, humeri obtuse, not incised as in the European siiecies; color 

 fulvous brown, tlie broad submargins and a few irregular transverse lines on the 

 disk posteriorly, and the calloiisities, i)Iackish. Scutelhun longer than in dorsalis, 

 sides parallel, apex regularly rounded; color fulvous brown, with darker verini- 

 culate markings, which in the male become finer and transverse along the middle 

 where they are interrupted, forming an irregular blackish patch on either sideof 

 the disk, and outlining an indistinct tiiangular apical spot; base with a short 

 longitudinal bhutk line on either side. Pronotuni and scutellum with a common 

 obsolete pale longitudinal median line. Conuexivum alternated with dark brown 

 and pale fulvous. Beneath black; coxal region, an ill-defined spot on the hind 

 edge of the mesopleura, legs and venter, obscure rufous, the latter becoming 

 darker toward the margins. Sides of the propleura strongly depressed, the edge 

 of the pronotum forming a broad slielf beneath. In the female the vermiculate 

 lines on the sctellum are more irregular and coalesce to form a blackish p:itch on 

 the disk either side of the middle; the colors below are more strongly contrasted, 

 and the femora and inner surface of the tibise are black. Length .5 to 6 mm. 



Described from one pair taken at Fort Collins, Colo., May 20, 

 1899, and a female from Independence, Cal., taken July ITtli by 

 Prof H. F. Wickham. Prof. Wickham has also sent me a nymph 

 taken July 27th at Hawthorne, Nev., and more recently Prof Gil 

 lette has sent me a long series taken at Fort Collins during May 

 and June, and Mr. Henshaw one trom Wyon)ing. The Fort Col- 

 lins types were sent to me by Prof Elmer D. Ball, an enthusiastic 

 collector and an able student of the Homoptera, to whom I take 

 much pleasure in dedicating this first described American species of 

 Oclojdoscelis. 



This species and that described below are best located in the genus 

 where I have |)laced them, although the head in tliese American spe 

 cies is longer and the humeri want the incision found in the European 

 species; the general form is afso proportionately longer, but all 

 other characters are those of Odontoscelifi. As this genus has not 

 before been recognized from our fauna, I have included in the 

 description given above a number of purely generic characters. 



OdontoNceliM prodiicta n. sp. 



Closely allied to the preceding l)Ut still more elongated. Head long, slKi]>ed 

 as in Camirns cordctin Germ., above strongly convex, sides subparallel for some 

 distance before the eyes, then obliquely truncated to the l)road rounded apex of the 

 tylus; color black, obscured by a detise coating of matted cinerous hairs above 

 and below; bncula; rounded. Pronotum proportionately longer than in Balli, 

 the margins not so broadly expanded, feebly sinuated anteriorly. Ui)per surface 

 of the wliole insect closely and finely punctured with brownish, and covered with
