NOTES ON AMERICAN TINGIDiE WITH DESCRIPTIONS 



OF NEW SPECIES.* 



By Herukrt (Jsbokx and Carl J. Drake. 



Since the publication of recent papers on Tingidae we have 

 examined a number of collections and specimens sent in for 

 determination by Professors Cooley, Lovett, Ewing, Swenk, 

 Doane, Ferris, and Melander. This material with our private 

 collections enable us to present the following notes. 



Atheas insignis Heidemann. 



Two specimens, one taken at Vienna, Virginia, August 8, 

 1913, by Mr. Barber and the other at Bladensburg, Maryland, 

 July 21, 189(3, by Heidemann. The Blandensburg specimen 

 bears the label, " Leptostyla exquisita Uhler MS," as identified 

 by Mr. Heidemann. 



Atheas mimeticus Heidemann. 



Four specimens; one specimen taken at Fort Collins, 

 Colorado, August 8, 1898, and the other three at Albuquerque, 

 New Mexico, August 30, 1888, by Wickham. The Colorado 

 specimen is a little darker than our New Mexican forms and 

 the color indicated in the original description and drawing, but 

 agrees in other characters. 



Atheas annulatus spec. nov. 



This species is closely allied to A. fuscipes Champion, from 



Mexico and Central America, but readily separated from it by 



the annulate first segment of the antennae, the much longer 



discoidal area, the brown transverse nervures along the inner 



row of cells in the costal area, and the testaceous legs. 



Pronotum feebly convex, closely punctate, distinctly tricarinate, 

 converging anteriorly; membraneous margins narrow, slightly concave, 

 with a single row of small, round or oval areolae and three extra cells 

 along the inner margin at the widest part just in front of the middle. 

 Head rugulose, a little broader than long, the antenniferous tubercles 

 stout, pointed and slightly divergent. Antennae slender, slightly longer 

 than froin the apex of head to tip of triangular process of the pronotum ; 

 basal segment constricted beyond the middle, and forming a fairly 

 distinct annulus, a Httle more swollen, and nearly one and a half times 

 as long as the second; third segment longest, slenderest; fourth segment 

 thickened, twice as long as the second and a little more than one-half 

 the length of the third. Rostrum reaching between the intermediate 

 coxae. Mesostemal laminae diverging posteriorly. Elytra reaching 

 considerably beyond the abdomen, rounded at the tip, widest before
