AMERICAN LEPIDOPTERA. 15 



Two specimens from Texas (Friedrich) examined in the Berlin Mu- 

 seum. Very distinct in appearance from any of its congeners. 



42. C'aiocala microiiympha, Guenee. 



%. — Anterior wings slightly dentate, costa arched to the apices which are 

 produced, chestnut brown varied with whitish grey and blackish. The two 

 median lines distinct but narrow, separated above but nearing below : t. p. line 

 strongly projected opposite the cell where it is bidentate, the inferior tooth 

 greatly reduced, afterwards uniformly waved, without a sinus on the sub-me- 

 dian nervure which is shaded with black along its entire length. Reniform re- 

 placed by a black streak. Median shade well defined, stopping at the cell and 

 thence ascending towards the terminal margin where it touches with black two 

 or three nervules. Subterminal line whitish, undulate or zigzag, nearly per- 

 pendicular, touching in passing the exerted tooth of the t. p. line. Hind wings 

 ochrey yellow, with a broad arcuated hind border, as usual interrupted and 

 forming a spot at anal angle; median band narrow, slightly angulated, with 

 two streaks of blackish scales joining it from the base. Beneath, the median 

 band is broader, especially at costa towards which it nearly spreads to base. 

 Primaries beneath entirely yellow to the first black band. 



I have not identified Guenee's description which I here translate. 

 Size and habit of the European C. protonympha, which it nearly 

 resembles. 



43. Catoeala polygama, Guenee. 



Differs from the European C. hymenea as follows: — % . — The anterior wings 

 are a little narrower, with the terminal margin more rounded, cinereous with 

 a slight greenish tint, much more shaded and powdered with ferruginous, es- 

 pecially behind the t. p. line where this color brings into relief the dentate sub- 

 terminal line. The ordinary lines are less clearly marked, their angles softened. 

 The t. p. line is more lightly waved and, above the s. m. nervure, makes a 

 profound sinus, broad, black and bordered with ferruginous. The median band 

 of the hind wings more constricted on the cell, beyond more greatly arcuated 

 or rounded and it is continued to the terminal margin. The hind broader is 

 less largely intruded upon by yellow scales at the apex and the spot at anal 

 angle is larger. The second joint of the palpi is notably securiform and the 

 third slightly spatulate. 



I translate Guenee's description. I have before me a number of 

 specimens (Canada to Virginia) which differ in appearance among 

 themselves but which I cannot separate into species, and which I refer 

 to Guenee's C polygama. The largest specimens are much shaded 

 with whitish before the ordinary spots, while the median space be- 

 hind is tinged with gliucous. The base of the fore wings is much 

 shaded with deep brown, while the subterminal space is bright brown 

 and usually strikes the eye. But again specimens are before me 

 wanting all pale and bright brown colors, uniform dull brown and 

 blackish and more like Guenee's indifferent figure. The expanse varies,
