THE CANADIAN ENTOMOLOGIST. 



Primaries broader, apices marked, but hardly acute ; 



vestiture thin ; color reddish PJu-agmatobia 



Primaries still broader, apices long acute ; secondaries sub- 

 caudate j size large AracJmis 



The synopsis shows plainly the close relation of some of the genera, 

 though the series is arbitrary in its arrangement. Excluding the 

 Cydosiince, which perhaps indicate a tendency to the Noctuidse, we have 

 two fairly distinct series. In the one we find a usually small head, 

 somewhat retracted, and more or less obsolete tongue. The antennas are 

 moderate in length or short. In the other series, the head is larger, more 

 free, the tongue stronger and longer, and the antennae are usually longer 

 and more prominent. The position and origin of vein lo serves as a 

 good basis of division, and this corresponds to some extent with the 

 other characters. The entire family needs further revision. The genera 

 allied to Arctia are scarcely sufficiently distinguished, and so Euhalisidota 

 seems scarcely distinct from Halisidota. 



Melanchroia, Daritis and Kodiosoma are not included in the synopsis. 

 Ectypia and Nelphe are placed partly by guess, from lack of types for 

 examination. 



Eupseudosoma has been sent me by Mr. Conradi, and is a close ally 

 of Halisidota, differing in the broader primaries, and very long oblique 

 outer margin. 



Finally, the present paper consists rather of a series of notes prepara- 

 tory to a study of the family, than a critical study. With a good collec- 

 tion at hand, there should be no difficulty anywhere in the family, except 

 perhaps in Halisidota.
