34 CATOCALA DESPERATA. 



very pale grey; the space frou tliis latt?r to tlie transverse posterior line is brown of no very 

 decided tint. 



Secondaries, base covered with greyisli iiairs, rest of wing blaclc, with broad pure white 

 fringes. 



Under surface, primaries M'hite, with black marginal, median and sub-basal bands, whicii 

 arc confluent near interior margin ; fringes white, with grey at the terminations of veins. 



Secondaries white, wiili broad black marginal and narrower mesial bands; fringes M'hite. 



The caterpillar which is figured by Abbot feeds on various species of oak. 



The commonest of all tJic black winged Catocahc, and is found in most localities from 

 Xew York to Florida. 



There has been the most interminable confusion in regard to the identity of this species ; 

 for years it has been confounded with, and represented in x'Vmerican collections the C. Viduafa 

 or Vidua of Gucnee, a larger and entirely distinct species peculiar to the Southern States; by 

 comparing the figure of the latter on plate III of this work with that of tlie present species on 

 plate V, the many obvious points of difference will be readily perceived without inflicting on 

 me the misery of pointing them out piecemeal.

Expands 3| inches. 



Head and throax, above, pale grey with dark brown lines ; abdomen bright oclirc yellow ; 

 beneath yellowish white. 



Upper surface, primaries greyish white with pale blueish and brown shades; transverse

 large and open ; fringes brown.

Habitat. Middle and Southern States, of rare occurrence. 



This has the appearance of being an improved edition of and is closely allied to C. 

 Xeogaraa, but can be easily distinguished from that species by its much greater size, the more 

 brilliant yellow of abdomen and secondaries, and by the open sub-reniform, also the ground 

 color of primaries is much lighter aiid the markings generally more prominent. 



The c? figure on plate IV, Vol. Ill, Proc. Ent. Soc. Phil., which accompanied IMr. 

 Grote's original description of C. Subnata, resembles it in size and shape, but the markings 

 mainly, and the colors precisely are those of Neogama, it has even the closed sub-reniform
