of areoles in the costal space except near the base ; hind wings less 

 spotted.

Habitat. — I have before me 8 males and 9 females. From Canada; 

 Upper Wisconsin River, Kennicott ; from Hamilton, Ontario, Moffcit ; 

 Michigan, a couple in alcohol, Capt. Meade ; Ludington, Mich., Pierce ; 

 Port Huron, Mich., Hubbard; from New Jersey, Uhler; from S. Caro- 

 lina, Zimmerman, the type of M. Talpi?ius Klug.; from Savannah, Ga., 

 the type of M. irroratus Burm., vol. ii., p. 995, No. 11, with the label in 

 Burmeister's hand-writing; from Millin, Scriven Co., Ga., July, by Morri- 

 son; from Florida, Norton. 



The range of the species is very large ; the largest specimens are from 

 Canada and Michigan, the smallest from Georgia. The wings are more 

 or less sprinkled. 



The species has been raised from a larva which I had supposed to 

 belong to Acanthaclisis congenej-, but Mr. Redtenbacher rightly doubted 

 my determination. I have besides the described larva from Wyoming 

 before me, one from Port Huron, Mich., and one from Crescent City, 

 Fla., both collected by Mr. Hubbard. I can not find any difference be- 

 tween them and a larva from Ludington, Mich., by Mr. Pierce, who 

 intends to describe the full history of the species raised by himself 



When I was still in Europe, I had determined " with some doubt " 

 this species as the Af. abdominalis Say. The large material now at hand 

 has shown me years ago that Say's species is a different one. As there 

 exist before Burmeister two different M. irroratus, Rambur's name has 

 the priority; his type is a female. The M. irroratum Oliv., Encycl., viii., 

 p. 126, No. 30 (copied by Walk., p. 408, No. 207), from Italy and Greek 

 Archipel., is probably M. imbed //us Stein, The AT. irroratus Klug., 

 Symb., pi. 35, f 6, from Arabia Felix, has visible spurs. The type is in 

 the Berlin Mus.; I can not determine the species, but believe it is not a 

 Creagris. After Mr. Taschenberg, there can be no doubt that the type 

 of Burmeister of his M. irroratus in the Halle Museum, is different from 

 his type in Winthem's Coll. The type in the Halle Museum is M. longi- 

 caudus Burmeister, after his type in Winthem's Coll. AI. contamiuatus 

 Burm. is the female of irroratus type (in Winthem's Coll.) ; Mr. Tas- 

 chenberg's description is conclusive. Af. uebu/osuin Oliv., Enc. Meth., 

 viii., 127, 35, from New York, is M. conspersus Rbr.; the description of
