34. EXARTEMA MELANOMESUM Heinrich 



(Fig. 83) 



Exartema melanomesum Heinrich, Proc. Ent. Soc. Washington, vol. 25, 



1923, p. 119. 



Cyolomia nortana Kearfott (ms), Ins. New Jersey, 1910, p. 539. 

 Cymolomia melanomem Forbes, Memoir 68, Cornell Univ. Agr. Exp. Sta., 



1924, p. 466. 



Kearfott never published a description of his nortana and the 

 name therefore has no standing. Moreover, all the specimens he 

 had set aside under that name except two from New Jersey are from 

 Manitoba and are a different species which I am describing else- 

 where in this paper (p. 154) as hrevirostratum. The specimen to 

 which he refers in the New Jersey list I found in the Barnes' collec- 

 tion after the description of vielanoinesutn. Otherwise I should have 

 used his manuscript name. 



Harpe of male genitalia of type figured. 



Distribution. — Maine and New Jersey. There is also a paratype 

 from Ithaca, New York in the collection at Cornell University. 



Alar expanse. — 15-17 mm.

35. EXARTEMA VALDANUM McDunnough 



(Fig. 89) 



Exartema valdannm McDunnough, Can. Ent., vol. 54, 1922, p. 38. 

 Cynwlomia micantana Forbes, Memoir 68, Cornell Univ. Agr. Exp. Sta., 

 1924, p. 464. 



This species is easily recognized by the narrow, clear white ante- 

 median and postmedian areas bordering the broad median fuscous 

 band on fore wing. 



Harpe of male genitalia figured from specimen in National Col- 

 lection from District of Columbia (male, Schoenborn). Female 

 genitalia as in permundanuin. ■ 



Distribution . — District of Columbia, New York, Massachusetts, 

 Maine, New Hampshire, Quebec, Ontario, Manitoba. Except the 

 types, these specimens (several of them reared) represent a large 

 series which Kearfott had set aside as a new species under the manu- 

 script name micantanuni but which he never described. 



Alar expanse. — 13-18 mm. 



Type. — In Canadian National Collection. 



Type locality. — Fort Coulonge, Quebec.
