margins, and elytra yellowish-gray. A rather large spot on each side 

 of the hood, an anterior and posterior area on each i:»ronotal margin, a 

 basal and an apical band on the elytra (also bullate pfirtion) fuscous- 

 Ijrown. Pronotum olive-brown. 



Type specimen labeled "Colo.," received from Prof. C. P. 

 Gillette, Fort Collins, Colorado. A second specimen from the 

 same state agrees in size and form, but is uniformly a trifle 

 lighter. 



Corythucha associata spec. nov. 



This species is quite like C. aesculce, the buckeye Tingid, it 

 being about the same size and of a similar color; but differs 

 from that insect by its shorter and narrower anterior portion of 

 the hood and the posterior portion is considerably more globose. 

 The position of the strongly deflected hood is between aesculce 

 and biilbosa. 



Moderately large and broad. Antennas beset with bristly hairs; 

 first segment swollen, three times as long as the second; second seg- 

 ment short; fourth segment swollen toward the ape.x. Rostrum 

 reaching between the intermediate coxas. Membranous pronotal 

 margins broad, bullate about the middle, slightly turned up posteriorly, 

 rather evenly reticulated, entire margins armed with closely set spines. 

 Hood more highly elevated than in aesculce, very abruptly constricted 

 near the middle; anterior portion short and narrow; globose portion 

 high and quite large. Pronotum punctate; triangular process retic- 

 ulated, the sides raised anteriorly, with a few distinct areola?. Median 

 carina considerably raised. Elytra broad, considerably longer than the 

 abdomen, broadly rounded at the tip, the outer margin slightly concave 

 and the inner apical margin obliquely rounded. Length, 4.1 mm.; 

 width, 2.4 mm. 



Color: General color brownish. Body above and beneath blackish. 

 Antennse yellowish; terminal segment slightly embrowned. Legs yel- 

 lowish; tips of tarsi brownish. Membranous pronotal margins hyaline, 

 with one or two spots embrowned. Hood infuscated, the center of a 

 few areolae hyaline. Elytra hyaline, with a broad band near the base, 

 another at the tip (except the distal part of the apical series of areolee 

 and two large cells within the band) and more or less of sutural area 

 fuscous. 



Described from a very long series of specimens, taken 

 during August and September at Clarksville, Tennessee, by 

 Messrs. Louis Stearns and E. H. Vance, on wild cherry. Primus 

 serotina. We have another specimen, taken June 25, 1915, at 

 Lexington, Tenn., by Mr. D. M. DeLong. This species differs 

 greatly from C. pruni by the larger hood, longer basal segment 

 of the antennae, etc.
