though coming nearer to that of some examples of Irene than to any 

 other. The markings of the primaries in the several males in my pos- 

 session are sufficiently distinct and pronounced, though not intensely 

 defined; in the two females before me they are heavier and accompanied 

 by dark brown shading more or less. The general style of marking is 

 that of IValshii, Arizo7ics and Aspasia, to which group it belongs. 

 Secondaries with mesial and marginal bands shaped much as in above 

 mentioned allied species; but the red ground color is far more pinkish 

 than in any of them, and exactly the same tint as in Amatrix. The 

 body is, beneath, tawny white, or inclining thereto; the wings differ in 

 nothing decided from allied forms. 



This is the insect taken several years since by the indefatigable Jacob 

 Doll in Arizona, and which, by some curious mistake, has been so 

 generally distributed as the C. Arizoncs, Grote, from which it is in a 

 moment distinguished by its warm maroon or reddish gray color, 

 whilst in ArizoncE the color is, as Mr. Grote says in the description, 

 "dark grayish brown, with a glaucous shade over the more grayish 

 median space." 



In Babayaga the lines of primaries are reddish brown (an intensifica- 

 tion of the paler ground color); in Arizonce, to use Mr. Grote' s words 

 in the description, ' ' black. ' ' Further, in Arizona', says its author, is "a 

 whitish shade before the brown-tinged broadly bis-annulate reniform;" 

 there is no vestige of any whitish shade in the remarkably even uni- 

 colorous surface of Babayaga. 



There are other differences of minor importance, but the above, 

 which have been carefully noted with the types of both Arizona- and 

 Babayaga before me side by side, will doubtless suffice. The descrip- 

 tion of ArizoncE is in the Can. Ent. Vol. V, p. 163, where any one 

 doubtful of the distinctness of the two, can convince themselves. The 

 original type of Arizona is in the Museum of the American Ent. Soc. 

 at Philadelphia. 



There are five insects in this group, all of a large size, that are easily 

 distinguished from each other, though whether they be of different 

 species or only varieties of one species, is for each one to decide as best 

 may suit his own pet theory in that direction. They are: 



IValsJiii, W. H. Edws. , with obscurely marked ashen primaries and 

 brick-colored secondaries. 



Arizona, Grote, with bluish gray, heavily marked primaries. Sec- 

 ondaries same red as in Walshii. 



Aspasia, Streck., with very pale, somewhat yellowish gray primaries, 

 with markings not as dark, and scarcely as pronounced as in Arizona, 

 and secondaries same color as the two preceding. 



Babayaga, Streck., with reddish gray primaries and markings of 

 deeper tint of nearly same color. Secondaries bright deep pink, same 

 color as in Amatrix.
