Albuna. nov. gen. 



Under this name I separate a number of species, which seem 

 to me to possess characters sufficient to form the types of a new 

 genus. Compared with ySgeria proper, and taking ^g. Acerni 

 as the North American type of that genus, the head is much 

 narrower than the front of the thorax, which is not so far pro- 

 duced beyond the base of the wings. The antennae are compar- 

 atively shorter, stouter and more thickened toward the apex. 

 The palpi are sHghtly longer and more porrect. . The legs are 

 shorter proportionately and the tibiae more densely clothed with 

 hair. The abdomen of the $ is never constricted at the base, is 

 stout, cylindrical, with the caudal tuft small, and not spreading. 

 That of the 2 is fusiform, quite as broad at base as the thorax, 

 and tapering to a point. The markings of the wings are 

 heavier and broader than in yEgcria, the discal mark being al- 

 ways oblique, and the space between the sub-median nervule 

 and the internal marginal nervule always covered with scales. 

 For the group, these are rather large insects, allied to Bejubecia, 

 but the antennae are not so deeply pectinated, the body is more 

 fusiform, and the caudal tuft is not spreading.

5. Fore wings with the whole surface very bright orange 

 red, the costal margin a little shading into golden brown, and the 

 corner of the nervules indicated by golden brown streaks. Hind 

 wings with the margin narrowly orange red. Fringes of both 

 wings golden brown. Beneath, the markings are repeated, but 

 the costal edge of the fore wings is lemon yellow. Head and 

 antennae black, the former with some blue metallic scales between 

 the eyes. Thorax with broad lateral and narrow basal stripe, 

 golden yellow. Abdomen with first, second and third segments 

 broadly banded posteriorly with golden yellow, fifth, sixth and 

 seventh wholly golden yellow, as is also the caudal tuft. Under 

 side of abdomen, palpi, coxae and all the legs golden yellow, the 

 tibiae banded at the joints with black. ?. Similar to the <?, but 

 a little more robust, the posterior segments of abdomen banded 

 with, but not wholly, golden yellow.

Fore wings with the costal margin broadly purplish brown, 

 the internal and posterior margins deep golden yellow, not by 

 many degrees of so red a shade as in the preceding species. The 

 nervules are marked by brownish streaks. Hind wings with 

 costal margin lemon yellow, the outer margin deep golden yel-
