This species most nearly approaches spumosum Grt., but its indistinct 

 maculation and ochreous colour readily distinguish it from this species. 



Catocala Beiitenmtielleri, n. sp. 



Ground colour of primaries an even bluish-gray, slightly shaded 

 with darker, especially on outer margin. A black subbasal slightly dentate 

 line extends half across wing at base, and is terminated by a black basal 

 dash. The t. a. line is geminate, composed of a series of outcurved 

 lunules, extending from costa at about one-quarter of its length to middle 

 of inner margin, and shaded outwardly in costal portion with black ; very 

 prominently toothed basally on second anal vein ; reniform yellowish, 

 central portion outlined with darker, slightly toothed at apex and preceded 

 on costa by two dark shades, the basal one of which is most prominent • 

 subreniform similar in colour, faintly outlined with black j t. p. line single, 

 black, with two prominent teeth beyond cell, the upper of which is much 

 the larger ; the inward bend along second anal vein extends nearly to t. a. 

 line, and thence outwardly to a point on inner margin two-thirds from 

 base ; outwardly this line is bordered by a brownish shade, followed by 

 bluish-gray ; marginal area shaded with blackish, and containing a series 

 of elongate black spots ; fringes shaded with smoky. Secondaries orange- 

 vermilion, median black band fairly broad, somewhat attenuate in central 

 portion, sharply angled and not reaching inner margin ; black marginal 

 band broadest at costa, dentate at anal angle, bordered outwardly with 

 vermilion, most prominent near costa and shortly before anal angle; fringes 

 white, marked with black on central portion of wing. Beneath, primaries 

 reddish, with broad black median and terminal bands ; inner margin and 

 basal portion of cell shaded with black. Secondaries as above, lighter on 

 costal portion, no vermilion colour exterior to marginal band. Head and 

 thorax bluish-gray, collar crossed by darker bands. Abdomen reddish, 

 tufted with gray on anal segment.

Type, coll. Barnes. 



This species closely approaches verrilliana Grt., and in markings is 

 practically identical. It may be distinguished by the bluish-gray colour of 

 primaries and their much more uniform appearance, the contrasting shades 

 q{ verrillia?ia being almost totally lacking. It is probably merely a racial 

 form of this species. There is a tendency in the primaries to become 

 rather suffused, the markings losing the clear-cut appearance of the typical 

 specimens. We take pleasure in naming this species after Mr. W. 

 Beutenmueller, who has contributed so much to our knowledge of this group.
