ON SOME NORTH AMERICAN TINGID^E (HEMIP.)* 



Carl J. Drake. 



During the past three years the writer has been collecting 

 data and preparing to monograph the American species of 

 Tingid^e occurring north of Mexico. Through the kindness of 

 numerous workers many specimens have been studied from 

 various parts of the United States. As this paper will not be 

 completed for several months, it seems desirable to publish the 

 following notes and descriptions of new species. 



Corythucha montivaga, new species. 



Hood moderately large, slightly constricted near the middle, the 

 height equal to about three-fifths of its length, slightly longer than the 

 median carina and a little more than twice as high. Median carina with 

 large, long (mostly rectangular) areolse, nearly straight in the female 

 but slightly arched in the male ; lateral caringe moderately long, arched 

 near the middle and the areolae becoming smaller towards both the 

 anterior and posterior ends. Paranota with the reticulations slightly 

 smaller than those of the globose portion of the hood, the anterior 

 margins beset with a few spines. Lateral margins of paranota and 

 elytra unarmed. Elytra broad, the lateral margins narrowed and 

 rounded posteriorly; costal area triseriate. Tumid elevations narrow, 

 moderately high and pointed. The elytra (taken together) are subequal 

 in width (near base) and length, the entire insect being broadly ovate 

 in outline. 



General color yellowish brown with fuscous markings. Greater 

 portion of hood, part of paranota and spot on median carina fuscous. 

 Elytra with a band across the base and apex fuscous; both bands con- 

 tain partly hyaline areolae and the apical band extends along the apex 

 of the elytra. Sutural area with fuscous markings. Body beneath black. 



Length, 3.4 mm. ; width, 2.2 mm. 



Type (male) and allotype (female) ,■ collected on Bear Pw. 

 Mt., Montana, Septembers (from the late McElfresh collection). 

 Akin to C. padi Drake, but readiy separated from it by the 

 slightly elevated hood, the shape of the median and lateral 

 carinae and the lateral margins of the elytra.
