2 <?. — This interesting species, the Hist of the genus known to inhabit 

 the American continent, and the second species known, differs from Cjlitrl- 

 caria of" Europe in the rather broader wings, both pairs being much less 

 excavated on the outer edge. The antennae are much 

 the same, and the markings similar in the two species. 

 Body and wings deep lemon-yellow. Fore wings with 

 four nearly equidistant, large, conspicuous, brown, costal 

 spots. From the third arises a broad, diffuse, sinuous, 

 brown shade, extending on to the hind wings, and forming a slightly-curved 

 median hand. Fringe concolorous with the wings ; apical half of fore wings 

 brown, checkered slightly with brown on the hind wings. Beneath speckled 

 slightly with brown. Four faint discal spots. Two outer costal spots only 

 present; from them arise two faint bands, interrupted by the venules. A 

 single outer line on the hind wings about half-way between the discal spot 

 and the outer edge of the wing. 



. Length of body, <?, 0.50; of fore wing, 0.70; expanse of wings, 1.50 

 inches. 



Oregon (Harford); Colorado Territory (Hidings); Denver, Colo., 

 June 3 (Mead) ; Dakota Territory (Mus. Comp. Zool.). 



The line on the hind wing is less curved in the Oregon specimen than 

 in that from Colorado, and the latter is deeper yellow. The occurrence of 

 this genus on the Pacific slope of the continent is extremely interesting as a 

 link connecting the insect fauna of Western America with Eastern Europe. 



It differs from the European C. jiavaria in having broader wings, both 

 pairs being much less excavated on the outer edge. The antennae, are much 

 the same, and the markings similar in the two species. C. Jiavaria is 

 reported in Staudinger's Catalogue as occurring in Galicia, Hungary, South- 

 ern and Eastern Turkey, Middle Russia, and Armenia.
