Corythucha salicis spec. nov. 



Hood moderately elevated, abruptly constricted about the middle, 

 tapering in front and somewhat globose behind, widely reticulated, the 

 reticulations becoming smaller at the sides in front. Pronotmii with 

 the membraneous margins broad, renifonn, bullate about the middle, 

 and amied with a few spines on the anterior margins; median carina, 

 low, uniseriate (in some specimens with one or two cells divided near 

 the middle); lateral caringe raised anteriorly, with a few distinct cells. 

 Antennae clothed with a few long hairs, the first segment slightly more 

 swollen and twice the length of the second. Rostrum reaching between 

 the intermediate coxae. Elytra broad, the outer margin slightly 

 convex; costal area broad, \yith three rows of areolse, the reticulation 

 very large between the transverse fascias. Claspers in the male strongly 

 curved. Length, 3.5 mm.; width, 1.9 mm.

 testaceous. Legs yellowish-brown, the tip of tibiae and tarsi infuscated.

 posterior portion of tumid elcA^ation embrowned. Body beneath black, 

 the genital segment more or less embrowned. 



Middlesex Falls, Massachusetts, Wisconsin (DeLong) and 

 Bozeman, Montana, June 4, 1912 (Cooley). This species 

 infests willow and currant. Although very distinct it is 

 probably most closely allied to C. arciiata Say. We have seen 

 this species labeled ''Corythucha fiiscigera Stal, " in eastern 

 collections, but it is very distinct from our Mexican speci- 

 mens of this species. 



Corythucha marmorata Uhler. 



The color of this species is somewhat variable and in some 

 specimens the marmorate markings on the elytra are more or 

 less evanescent. We have specimens from Nebraska, Indiana, 

 Michigan, Ohio, Pennsylvania, Maine, Massachusetts, New 

 York, Georgia, Tennessee, Louisiana, Iowa and Colorado. 

 This species has been reported as causing damage in green- 

 houses. 



Corythucha morrilli spec. nov. 



This species was given the manuscript name of C. morrilli, 

 by Mr. Heidemann in honor of the excellent work that Dr. 

 Morrill has done in this genus. 



Hood highly elevated, rather narrow, not very widely reticulate, 

 moderately constricted back of the middle; anterior portion long, the
