doubtful as to the status of the present species, which was de- 

 fined as follows : "Thorax as in aspcra LeC, elytra with the 

 humeri subacute; disk sculptured zmtli distinct tubercles, 

 which usually show a serial arrangement, alternate series larg- 

 er and not at all rugose." 



Habitat. — California (Siskiyou County, collections U. S. Na- 

 tional ]\Iuseum). 



Papulosa is larger and more robust than granulala, and us- 

 ually of an intense black and feebly shining. The pronotal 

 punctuation is like that of Upis ceramboides, only that the punc- 

 tures are distinctly separated and not coalescent. The elytral 

 tuberculation is almost like that observed in granosa. (See p. 

 i3i,Bull. 63, U. S. Nat. Mus.)

Key to the Nearctic Species of Gargaphia with the 

 Description of a New Species (Hem., Heter.) 



By Carl J. Drake, Ohio State University, Columbus, Ohio. 

 The genus Gargaphia Stal is represented by five described 

 Nearctic species and a new one is added herein. The genus 

 can readily be separated from the other genera of the Tingidae 

 by the transverse, sinuous carina which interrupts the rostral 

 sulcus between the meso- and metasternum. 



Key to the Nearctic Species of Gargaphia. 

 I — Elytra broad, costal area with four or more rows of a'-eolae at its 



widest part 2 



Elytra narrower, costal area with not more than three rows 0I 



areolae at its widest part 4 



2 — Lateral membraneous pronotal margins widely expanded, with fivt 

 or more rows of areolae at its widest part; first segment of the 



antennae blackish G. solani Heid. 



Lateral membraneous pronotal margins narrower, with not more 

 than four rows of areolae at its widest part; first segment of 



the antennae testaceous 3 



3— Size small (less than 3.5 mm.) ; membraneous pronotal margins an- 

 gularly expanded about the middle G. angulata Heid. 



Size larger (more than 4 mm.); membraneous pronotal margins 



rounded G. tiliae Walsh. 



4 — Costal area of the elytra narrow, with not more than two rows of 

 areolae at its widest part ; membraneous pronotal margins very 

 narrow, strongly reflected, and forming an acute angle with 

 the thorax G. opacula Uhler.
