172 THE CANADIAN ENTOMOLOGIST. 



Sub-family Arctiin^.. 



This term as here used embraces all the other Ardiidce. I wish to 

 say definitely, however, that I believe we have here at least three good 

 sub-families, and the term is used here simply to separate off the Cydesiince, 

 which have been properly limited. 



Mr. Hy. Edwards uses the term Pericopidce for the genera Gnop/mla 

 and Melanchroia, in Ent. Amer., III., 227, placing them between the 

 families Lithosiidce and Ardiidce. Mr. Grote, in his " New List," placed 

 Gnophoela between Ctcfiudia and Harrisina; genera, with which it has 

 not even a habital, much less a structural resemblance, Melanchroia he 

 omits altogether. I do not adopt Mr. Edwards's suggestion because I 

 have not studied Melanchroia, and cannot find any satisfactory Hmit from 

 Gtiophcela alone. The group is rather tropical than temperate, Gnophoela 

 being from the southwest and west, and Melanchroia still more typically 

 southern — Key West, Mexico, Texas, Arizona. I place the two genera 

 at the head of the series, on account of their Lithosiid tendencies.

The ocelli are present, the eyes small, round and prominent, and the 

 head as a whole, small. Tongue rather long and strong, palpi slender, 

 drooping, with loose thin vestiture. Antennas elongate, in the male 

 heavily and lengthily bipectinated. Legs, subequal, smoothly scaled, the 

 usual spurs small. Primaries with 1 1 veins, one of the series from the 

 end of the sub-costal wanting, 3, 4 and 5 are from the median at the end 

 of the cell, 5 rather close to 4, cell closed by a curved vein : 6 from the 

 end of the subcostal on. a very short stalk with 9, which runs to the apex 

 and gives off one vein about half way to tip. Vein 10 is from the sub- 

 costal before the end of the cell. Secondaries with 3 and 4 on a stalk 

 from the end of the cell ; 5 from a short spur cross vein, not far from the
