AMERICAN LEPIDOPTERA. 



who says: "je l'ai recue egalement de l'Amerique Septentrionale, ou 

 elle ne differe en riea de nos individus europeeens", in speaking of C. 

 fraxini, must have erred in his locality, for C. fraxini does not occur 

 in North America. Expanse 74 to 77 mm. 



More commonly taken in Canada and the Eastern States, C. relicta 

 is rare in Pennsylvania and I have seen no specimens from the South. 



10. Catocala califoruica, Edwards. 



9 . — This species resembles the European C. elocata, and is another 

 instance of the affinity existing between the Californian and European 

 faunae. Our species from the eastern slope which resemble C. califor- 

 nica, C. elocata and C. nupta, with powdery grey ornamentation of pri- 

 maries and straighter lines, differ by the more oblique external margin 

 and produced apices. C. californica has the secondaries dark rose 

 red. The median black fascia is not constricted but terminates rather 

 abruptly much before the margin. Expanse 58 mm. 



11. Catocala briseis, Edwards. 



9 . — I have seen a single specimen of this species which is recog- 

 nisable from the unusually dark primaries relieved by the white 

 dentate shadings of the subterminal line. It is stouter than C. califor- 

 nica but a smaller species than 0. unijuga. My detailed description is 

 lost and I have no longer the specimen in my keeping. New York 

 State. 



12. Catocala unijuga, Walker. 



£ 9 • — A fine large species with dark powdery grey primaries. Transverse 

 anterior line indistinctly geminate with an evident internal white shade. Disc 

 before the ordinary spots pale and the subreniform is paler than the large con- 

 colorous bisannulate reniform. T. p. line without very prominent teeth but 

 broadly marked and inflected on s. m. interspace. Subterminal line distinct 

 and evenly dentate, preceded by a distinct white coincident shade. Wings 

 strongly dentate. Secondaries bright red. Median band not constricted medi- 

 ally, tapering obsoletely towards internal margin which it nearly attains. Be- 

 neath the band terminates abruptly long before the margin. Expanse 72 to 80 

 mm. 



Not uncommon in Canada and the Eastern and Western States. 



13. Catocala junctura, Walker. 



I have seen the specimen in the British Museum described by Mr. 

 Walker. It seemed to me to differ principally from C. unijuga by the 

 more attenuate median band of the secondaries. I have a specimen 

 before me, which I doubtfully refer to this species, received some time 

 ago from R. Stratton as collected in Maryland and which differs from 

 C. unijuga in the less distinct subterminal line and obsolete white shad-
