DESCRIPTIONS OF NEW NORTH AMERICAN 



TINGIDiE/^ 



Carl J. Drake. 



Corythucha platini new species. 



Hood moderately elevated, abruptly constricted at the middle, 

 about one and a half times as long as high, the width and height of 

 globose portion subequal. Median carina noticeably less than one-half 

 of the height of the hood, not strongly raised or strongly arched at the 

 middle, its length subequal to length of hood. Lateral carina not 

 widely separated from the hood, with five or six distinct areolae, highest 

 near the- middle, the areolae becoming smaller towards both anterior 

 and posterior ends. Margins of paranota and elytra with spines much 

 reduced or entirely wanting, the anterior margins of paranota with 

 spines nearly normal. Tumid elevations of elytra normal. Rostrum 

 extending to meso-metastemal suture. Costal area of elytra with three 

 rows of areolae, the outer margin nearly straight. Length, 3.7 mm.; 

 width, 2.1 mm. 



General color pale testaceous, a few of the nervelets embrowned. 

 Body beneath piceous. Legs and antenna brownish, the tips of each 

 darker. Areolae hyaline. Hood with some of the nerv^elets brown. 

 Pronotum pale brown, the posterior portion becoming lighter; paranota 

 with two or three nervelets in front of the middle usually brown. Elytra 

 with a spot on the tumid elevation, a narrow band near the base, and a 

 very narrow oblique band near the apex brown. In both bands the 

 areolae are hyaline and the apical one is more or less indistinct. 



Six specimens from California; Kerman, April 26, 1917, 

 and Fresno. This insect infests the sycamore tree, but it is 

 quite distinct from either Corythucha ciliata Say or C. con- 

 frater?ia Gibson. In general appearance it somewhat resembles 

 C. drakei Gibson or C. essigi Drake. OfT-color or teneral 

 forms of C. obliqua Osborn and Drake somewhat resemble 

 platini, but the low median carina of the latter readily 

 separate the species. Types in my collection.
