Habitat.— Arlington, Va. 



Type in Coll. A.shmead. 



Described from a single s]>ecimen, which is readily distingui.she*! 

 from T. americatia by the rugo.sity of the vert«^x, collar, and scutelluin. 



XBNOMERUS W.ilk.r. 



Ent. MiVf,'., Ill, p. :>.".."> (1K^«). 



(Type A. <'»v/fHHrt Walk., <? ; Tekas nutlou 'Wn\]i., 9-) 



(I'l. VIII. Kig. 8. (?.) 



Head large, trausver.se, bioader than the thorax, the oc<'i|)ut slightly 

 emarginated, with a delicate margin; ocelli three in a triangle, the 

 lateral away from the margin of the eye; eyes rounded, pubescent. 



Antenna' 12-.jointed iti both .sexes, inserted on the clypeus, in 9 

 terminating in a 5- or ti- Jointed club, in S pe«licelIate-nodose. with whorls 

 of long hairs. 



Maxillary palpi .'i-jointed. 



Mandibles bidentate. 



Front wings as in Teleas, with a long marginal vein and a short 

 stigmal. 



Abdomen broadly oval, the first and second segments short, the first 

 about twice .as wide as long, both striated, the third segment large,

 .slender; the basal joint of the l.'ud tarsi more than twice as long as 

 the .secon<l; claws simple. 



The genus is readily distinguished in the male sex by the verticillate 

 antenna', and in the female from Tried,", Promcnntha, and allied genera 

 by having distinct mesonotal furrows; from 7Vm«6'aM//u/, which also 

 has mesonotal fnnows, it is distinguished by having a single post- 

 scutellar spine. 



Zenomerus pallidipes, rsp. iiov. 



9. Length, 1.4"'"'. Polished black, shining, sparsely pubescent; 

 head transverse, with the eyes slightly wider than the thorax, the lat-
