A NEW TINGID FROM TENNESSEE. 



Carl J. Drake. 



The genus Leptostyla, founded by Stal in the Eniimeratio 

 Hemipterorum, Band. Ill, p. Ill et 125 m 1873, was based on 

 three new species of Tingitidee from Rio Janeiro, Brazil. Dr. 

 Stal also referred the Nearctic species, Tingis oblonga to the 

 genus Leptostyla. In the Biologia Centrali- Americana (Rhynch., 

 Vol. II, p. 11, 1897) Dr. G. C. Champion amplifies Stal's generic 

 description of Leptostyla and describes seventeen new species from 

 Central America. 



The new species of Leptostyla described herein was taken 

 about fifteen miles west of Clarksville, Tennessee, July 25th, 

 1915, by Mr. D. M. De Long while sweeping for Jassids. This 

 pretty little species is quite distinct from the onl}^ Nearctic 

 congener, L. oblonga Say, and can be easily differentiated from 

 it by the following key: 



First segment of the antennae about three and a half times as long as the second; 

 costal area of the elytra without a broad fuscous fascia just before the 

 middle L. oblonga Say 



First segment of the antennae twice as long as the second; costal area of the 

 elytra with a rather broad, dark, fuscous, transverse fascia just before the 

 middle L. costofasciata n. sp. 



Leptostyla costofasciata spec. nov. 



Somewhat closely allied to L. const ricta Champion, but 

 readily separated from it by the longer third segment of the 

 antennae, the trispinous head, the more heart-shaped anterior 

 portion of the pronotum, and the much less constricted elytra. 

 From the only described Nearctic congener, L. oblonga Say, 

 it is quite distinct and can be readily separated from it by the 

 characters given in the key, and, also, by the rather blunt 

 and less prominent spines upon the anterior portion of the head. 



Body moderately long and comparatively broad. Head short, with 

 three rather blunt, porrect and slightly upwardly directed spines — the 

 two smaller slightly converging spines situated just above the antennae 

 (one on the inner side of each) ; the larger, frontal spine is just above 

 the other two; it extends a little farther forward and is slightly curved 

 downward. Eyes rather prominent, strongly faceted; the facets 

 giving them a morular appearance. Antenna; slender, about one-half 

 the length of the body; first segment swollen, twice as long as the
