THE CANADIAN ENTOMOLOGIST 81 



This European species has recently been reported from Quebec and Nova 

 Scotia. Its characters are discussed by Barber in one of his valuable papers 

 on the L\-gaeidce/ where he makes the comment, "The species has not yet been 

 found within the United States, but it should occur in the mountainous parts 

 of New England and New York." Boreal forms are likely to occur anywhere 

 in Maine, becoming restricted to mountainous regions as their range extends 

 southward.

Corythiicha marmorata (Uhler). 31 July, '19. 

 Coryihticha juglandis (Fitch). 10 Aug., '19. 



Corythucha pyrifcrmis, sp. nov. 



Membranous portions very clear hyaline, the surface shining; disc of pro- 

 notum brown; dorsal veinlets of hood very slightly marked with brown; paranota 

 with a single distinct dark brown spot before middle; median carina with a very 

 indistinct brown spot : lateral carinse and apex of angulate process white with a 

 brownish tinge. Hemielytra with distinct dark brown basal and apical bands, 

 the latter equal in width to one-third entire length of hemielytron, enclosing 

 three or four large, almost entirely hyaline areoles, the apical row of areoles 

 largely hyaline from apex of wing inwardly. Antennae, legs except tarsi, and 

 edges of plates forming rostral groove yellow. 



Hood slightly higher than median carina and somewhat longer, its height 

 one-half its length, its width not quite one-third width of entire pronotum 

 (14—46); hood pyriform, slightly constricted, sides convergent anteriorly and 

 but slightly concave as viewed from above, anterior lobe thus not distinctly- 

 marked ofif ; dorsal areoles very large ; hood as seen in profile very slightly rounded 

 above except at ends, moderately arcuate as a whole. Median carina slightly 

 shorter than hood (24—26), slightly and angulately arched, with two rows of 

 areoles at middle, its height less than one-third its length (7—24). Lateral 

 carinae moderately developed, with three or four areoles, terminating far from 

 base of hood. Paranota large, unusually expanded anteriorly and together 

 widest well before middle. Costal margin of hemielytra nearly straight; 

 marginal spines of paranota and hemielytra few and rudimentary; discal eleva- 

 tions of moderate size, with sharp dorsal edge, not strongly inflated; costal area 

 largely triseriate; hemielytra broadly rounded at apex. Antennae with numerous 

 setae. Length cf 4.08 mm.; width 2.34 mm. 



Holotype d", Peaks Island, Maine, 31 July, '19, (G. A. Moore), in my 

 collection. Paratype (f , Franconia, New Hampshire (Mrs. A. T. Slosson), in 

 Mrs. Slosson's collection. 



This species is closely related to pruni Osborn and Drake, although h\ 

 following Gibson's key* strictly it runs to hoodiana Osborn and Drake. From 

 the former it may be distinguished by the structure of paranota and hood, the 

 slight development of marginal spines, and broader form. The latter, known 

 only from Oregon, is described as larger (length 4.3 mm.), with strongly con- 

 stricted hood.
