THE CANADIAN ENTOMOLOGIST. 197 



Two species, Inopiuatus Hy. Edw., and Oregoneusis Stretch, I have not 

 examined ; the latter species I have been shown, without making any 

 notes upon it, in difterent collections made in New York State. 



The most unusual species is Perlevis, with its partly red secondaries, 

 and which is smaller than the rest and somewhat narrow-winged. Pudens 

 is a thinly scaled, whitish form, looking like, but slenderer than Collan's* 

 A female specimen of Spraguei which I saw in Mr. Von Meske's collec- 

 tion, from Texas, had the stripes tinged with yellowish, not so purely 

 crimson as in my male type from Kansas. Zonalis, Spmguei, Elegaiis and 

 Vivida are, perhaps, the handsomest species in the genus and are not 

 inferior in beauty, from the contrast offered by their colors, to the species 

 of Ardia. The brilliantly tinted stripes and bodies are set off by the 

 neutral tints of the wings. I have elsewhere drawn a parallel between 

 this genus and Ctcnucha in form and color, which is interesting ; the 

 metallic sheen of Cteimcha is wanting in these soft colored species of true 

 Ardiidce. 



ARSILONCHE AND LEUCANIA. 



BY JOHN B. SMITH, BROOKLVX, N. Y. 



During the past two years I have found on the exchange lists of most 

 northern, and ail Canadian collectors with whom I have done any ex- 

 changing, Arsiloiiche albovenosa Goetze under its synonym Ablepharon 

 Henrid Grt., and on their list of " wants " as uniformly appeared Leiicania 

 phragmitidicola Guen. I always sent for Arsilonche, and always received 

 LeJicania phragmitidicola. The latter is a common insect, but the former 

 is more rare, and it may be interesting to know how the two can be dis- 

 tinguished. Superficially they are very much alike ; generically they 

 differ as follows : Arsiio?ic/ie has lashed eyes, Leiicania has them hairy ; 

 the tongue in Arsilonchc is weak and short, in Leucania long and f :orneous ; 

 the legs in the former are shorter and more compact than in the latter, and 

 the spurs of middle and posterior tibiae are much shorter. The vestiture 

 of Arsilonche on thorax and body is entirely hairy, fine and long \ in 

 Leiicania the hair is somewhat flattened, more scale-like and shorter 

 Arsilonche has also the head more retracted, the abdomen longer and the 

 primaries rather more lanceolate. The secondaries in albovenosa are pure 

 white, in phragmitidicola they are more smoky and have a darker border.
