Megalopygidce. 

 Megalopyge lapena Schaus. 



Megalopyge lapena Schaus, Jour. N.Y. Ent. Soc, IV., 58 (1896). 



Gasina lapena Druce, Biol. Cent. Am. Hot. II., p. 432, 

 PI. 86, fig. 13 (1897). 



Three cf s and one 9 of this species, taken in Chiricahua Mts.,. 

 Ariz., and Palmerlee, Ariz. (Aug.), are before us. 



PyraustincE. 

 Edia scmiluna Sm. 



Lythrodes semiluna Smith, Can. Ent. 37, p. 67 (1905). 



Cynaeda bidentalis Barnes & McDunnough, Cont. Nat. Hist. 

 N. Am. Lep. I, (5) 33 (1912). 



Edia microstagma Dyar, Proc. U.S. Nat. Mus. 44, p. 320 (1913). 



A recent study of the unique type of semiluna Sm. proves 

 conclusively that Smith's generic reference was faulty, as the 

 species is a Pyraustid and identical with bidentalis B. & McD. 

 There seems but little doubt that Dyar has redescribed the same 

 species, creating the new genus Edia for its reception; as a new 

 genus is probably necessary, the synonymy will be as stated abo\'e. 



Noctiielia castanealis Hist. 



Orobena castanealis Hulst, Tr. Am. Ent. Soc. XIII., 157 (1886). 



Thalpochares jativa Barnes, Can. Ent., 37. p. 213 (1905). 



An examination of the type specimen oi jativa shows it to be a 

 Pyraustid and, without much doubt, identical with castanealis 

 Hist., although we have not seen the type of this latter species. 



Mr. Norman Criddle, of Treesbank, Manitoba, has been 

 appointed a Field Officer of the Division of Entomology, Ottawa, 

 to carry on investigations in Southern Manitoba. 



Mr. L. S. McLaine, M. Sc, has been appointed a Field 

 Officer of the Division and is now engaged, through the courtesy 

 of Dr. Howard, in the rearing and collection of the parasites and 

 predaceous enemies of the Browm-tail and Gipsy Moths in Massa- 

 chusetts, in connection with the work of establishing the same in 

 New Brunswick.
