Corythucha crataegi spec. nov. (Plate X, fig. f). 
This species was listed by Morrill in Psyche, Vol. X, p. 132, as a new 
subspecies of C. arcuata under the name of Corythucha arciiata crataegi. 
Morrill finds the eggs of the oak- and hawthorn-inhabitating .species to

distinct species. 
Antennae slender, beset with numerous bristly hairs of various lengths; first 
segment about three times as long as the second; fourth segment swollen on the 
distal half. Rostrum reaching the meso-metasternal suture. Hood considerably
