284 THE CANADIAN ENTOMOLOGIST, 



NOTE ON THE GENUS DYARIA, NEUM. 



In re-examining the old slide from which the figure of venation (Can. 

 Ent., XXV., 214) accompanying the original description of this genus 

 was made, I see distinctly three internal veins in the hind wings. It 

 would appear as if one of them must have been obliterated by the balsam 

 in the fresh mount, or else an error of observation was made. The 

 correction refers the genus to the Pyralidse and, according to Hampson's 

 classification, to the Epipaschiin^e, where it appears allied to the Indian 

 genus, Ccenodomus, Wals. (Hamps. Trans. Ent. Soc, Lond., 1896, 467.) 

 I would not lay any stress on the apparent presence of the accessory cell 

 in Dyaria. Vein 10 runs so closely approximated to the stalk of 6-9 that 

 it is impossible to be sure whether there is a true anastomosis toward the 

 tip or not in the single specimen mounted. 



It is rather curious that the error in Mr. Neumoegen's figure has been 

 exactly paralleled by Prof Aurivillius, who figures Alippa anomala 

 ( = Ccenodomus Hockingii) with only two veins in the hind wings. He 

 referred his genus to the Limacodidae ! This figure (Alippa = Ccenodomus) 

 much more nearly resembles Dyaria than Hampson's does ; in fact, there 

 is no tangible difference, as he gives vein 6 stalked, and specially illus- 

 trates vein ID running close to the stalk of 6-9, and nearly touching this 

 at the bend before apex. He also italicizes the words, " vein 8 of hind 

 wings touching 7 beyond the end of the cell." (Ent. Tid., XV., 176, 

 1894.) 



At my request, Dr. Hulst has examined the type of Dyaria in the 

 Neumoegen collection, and says : "Palpi upturned, thickly scaled in front, 

 rather short, not over half of the front, end joint very inconspicuous, basal 

 joint not hollowed out ; maxillary palpi very small." In the ? before 

 me the maxillary palpi are small, tufted with scales at the end. Of the 

 antennas. Dr. Hulst says " strongly bipectinate for two-thirds, then rather 

 suddenly shortening, the rest filiform. Process present behind at base, 

 fringed and crowned with long hairs." Dyaria may therefore be referred 

 to the Pyralidffi near Ccenodomus. Its occurrence in North America 

 needs verification, in spite of the positive statement published.
