4 AUG. R. GROTE. 



by a white shade ; subtcrminal space dull brown, not as in C. viduata and the 

 preceding; species bright brown. Fringes of secondaries pure white. Thorax 

 bright grey with the black markings distinct. Expanse SO to 85 mm. 



Common throughout the Middle and Southern States in various 

 localities. 



6. Catocala retecta, Grote. 



% 9 . — This species closely resembles C. desperata, but it is smaller. 

 The diffuse black median shade is wanting. The black longitudinal 

 dashes at base, across the t. a. line, and across the t. p. line on sub-me- 

 dian interspace, are very distinct and the two subequal teeth of the 

 transverse posterior line are, as usual, shaded with black. Beneath 

 much as in C. desperata. Expanse 70 mm. Length of body 30 mm-. 



A few specimens examined from the Middle States. 



7. Catocala flcbilis, Grote. 



% 9.— Peculiarly pearly cinereous, quite unlike in tint of primaries to any 

 of its allies, than which it is smaller. The black longitudinal dashes of C. des- 

 perata and C. retecta, are less prominent. Transverse lines not geminate, fine, 

 distinct but fading towards internal margin. Reniform vague, with a narrow 

 outer whitish ring and nearly filled with a pale brown center; subreniform en- 

 tirely open, concolorous, slightly touched with blackish from the diffuse shad- 

 ings crossing the t. a. line. Subterminal line very indistinct. The usual black 

 shading running upwardly from the teeth of t. p. line to external margin. 

 Hind wings very black with white fringes. Beneath body and base of wings 

 white. Differs by the narrowness of the white space between the central 

 black fascia and the broad border on hind wings. Primaries have a whitish 

 blotch on cell and external white facia nearly obsolete. Expanse 66 to 69 mm. 



Several specimens examined from Pennsylvania. 



8. Catocala tristis, Edioards. 



% 9 ■ — I have seen but two specimens of this pretty little species 

 from New York and Pennsylvania. It is readily recognisable from 

 the secondaries being unhanded beneath. It is the smallest known 

 species with black secondaries, and resembles rather C. gracilis or even 

 C. androphila, than the species with which I here associate it from the 

 color of its secondaries. My detailed description is lost with my ori- 

 ginal MS. and I have returned my material. 



9. Catocala relicta. Walker. 



% 9 • — This is the North American representative of the European 

 Catocala fraxini. In the male the primaries above are nearly entirely 

 white and the blackish powdery ornamentation is subobsolete. The 

 female is darker and has the lines of the primaries evident. The nar- 

 row central fascia of the secondaries is pure white. It cannot be mis- 

 taken for its European ally, than which it is a little smaller and Guenee,
