BARNES AND McDUNNOUGH: CATOCALA 33 



desdemona, which is generally paler in the coloration of both wings (Fig. 14) but which occasionally, in the female, shows 

 a similar brown suffusion to that of the Texan form. We know nothing regarding calphurnia Hy. Edwards, described 

 from a single specimen in the Bailey Collection ostensibly from Kansas; according to Beutenmuller, the species may be 

 either European or an aberration of delilah; we leave it as the latter for the present. The larva of desdemona has been 

 bred by us; it remains to be seen if the larva of the type form shows any distinctive features. 



The species is southern and southwestern in its distribution; it occurs in central Texas and apparently extends up 

 the Mississippi Valley as far as southern Illinois, as French (Can. Ent., XVIII, p. 161) records the capture of two speci- 

 mens in the vicinity of Carbondale. Snow records it as rare at Lawrence, Kansas (Trans. Kan. Acad. Sci., IV, p. 51). 

 The race, desdemona, as already stated, occurs in Arizona and Utah and probably will be found in New Mexico and 

 adjoining states. 



Catocala andromache Hy. Edwards

 Catocala andromache Hy. Edwards, 1885, Ent. Amer., I, p. 50. 



This small species resembles a miniature desdemona. Nothing is known of the early stages. It is entirely confined 

 to the arid regions of the Southwest, occurring fairly plentifully at considerable elevations in Arizona and southeastern 

 California and presumably extending into Mexico. 



Catocala frederici Grote 



Plate VII, fig. 12; PI. XXI, figs. 16 and 17 (claspers). 

 Catocala frederici Grote, 1872, Trans. Amer. Ent. Soc, IV, p. 14. 



This rare species is readily distinguishable from its allies by the pale gray color of the primaries. 

 It is found in central Texas and has been recorded by Snow from Kansas and northern New Mexico. This latter 

 record needs verification; it may refer to andromache, which was undescribed at the time. 



Catocala chelidonia Grote 



Plate X, fig. 9; PI. XXI, figs. 18 and 19 (claspers). 

 Catocala chelidonia Grote, 1881, Papilio, I, p. 159; 1882, 111. Ess. Noct. North Amer., p. 67, PI. iv, fig. 41. 



The dark blackish color of the primaries is quite characteristic of the species. 



The early stages are unknown. Packard (5th Rep. Ent. Com., p. 175) records the food-plant of the larva as scrub 

 oak, according to Mr. J. Doll. 



The species has only been recorded from the mountain ranges of Arizona, where it may be taken in the daytime by 

 beating the bushes and at night at the flowers of the mescal. 



Group XIII 



Egg hemispherical, vertically ribbed. Larva smooth, without dorsal warts or lateral filaments. Male claspers 

 symmetrical. 



The early stages of the species included in this group are too little known to allow of the grouping being anything but 

 tentative. Considerable difference occurs between the ova of illecta and abbrematella, the only two species whose egg 

 stage has been noted. The larvse are apparently of a rather primitive type and are feeders on various papilionaceous 

 trees (Gleditschia, Robinia, etc.). The adult illecta differs from its allies in possessing four rows of spines on the tarsi and 

 may eventually be found to belong in a section by itself.
