12 BARNES AND McDUNNOUGH: CATOCALA 



Catocala sappho Strecker 



Plate I, fig. 14; PL XVIII, figs. 31 and 32 (claspers). 



Catocala sappho Strecker, 1874, Lep. Rhop. Het., p. 95, PL xi, fig. 4. 



This is one of the rarest of the black-winged Catocala and is at once recognized by the large amount of whitish suffusion 

 on the primaries. Nothing is known of the life-history. The species was described from a single specimen from Texas 

 and has been recorded from Virginia, South Carolina, Florida, and various states of the Ohio and Mississippi valleys. It 

 is probably as wide-spread as the majority of the hickory-feeders, although seldom captured.

Figure 1 on plate I represents the males which are rather constant in color; the females are much more contrastingly 

 marked and more variable, several of the more marked forms being represented by figures 2, 3, and 5; figure 4 represents 

 a rare aberration, specimens of which, according to Beutenmiiller's manuscript, are contained in the National Museum 

 at Washington and in the Strecker Collection in the Field Museum at Chicago. The form subviridis Harvey, of which 

 barnesi French is a synonym, is characterized by the greenish suffusion over the primaries; a female from our own collec- 

 tion is depicted in figure 6. Holland's figure under this name (PL xxxi, fig. 4) is incorrect and should be referred to agrip- 

 pina; the maculation points to it being a female but the body looks like that of a male. 



Nothing is known of the early stages or food-plant. The species is distinctly a southern one, being fairly common in 

 Texas and the Gulf States and extending up the Mississippi Valley to the neighborhood of St. Louis, Missouri. It has also 

 been recorded as rare from New Jersey (Smith, 1910, Cat. Ins. N. J., p. 478), Pittsburg, Pennsylvania (Ehrman, 1895, 

 Ent. News, V, p. 212), and Ohio (Dury, 1877, Can. Ent., IX, p. 178). 



Group VI 



Egg (as far as known) flat, disk-shaped, with slight raised rim. Larva with lateral filaments, usually without a dorsal 

 prominence on the fifth abdominal segment. Male claspers more or less asymmetrical. 



When more is known of the early stages it may become necessary to subdivide the group; concerning the early stages 

 of dejecta, nebulosa, subnata, and euphemia, nothing is known, and these species are only tentatively included here; the 

 early stages of several other species are more or less incomplete, so that a definite arrangement is impossible. The known 

 larvae are all hickory- or walnut-feeders. 



Concerning the species with black hind wings, we doubt if they have all sprung from the same parent form; retecta 

 seems, both in the larva and in the genitalia, to be closely associated with residua and flebilis, but may be separated by 

 the presence of the lateral filaments in the larva; the other species show considerably more asymmetry in the genitalia 

 than the above species, the apex of the left clasper being rather broad and prominently extended beyond the thinly chiti- 

 nized area, while in the right clasper it is quite sharply pointed and scarcely projecting. 



In the yellow-winged species the same discrepancies occur; palceogama larva has a distinct wart-like ridge on the 

 dorsal portion of the fifth abdominal segment, but the species approaches close to lachrymosa in the form of the male geni- 

 talia; neogama has a larva approaching more the normal form but rather rougher in appearance; concerning the larvse 

 of the other species nothing is known.
