"238 PROCEEDINGS OF THE ACADEMY OF [May-Oct., 



Rio de Janeiro. November. Two males, two females. [U. S. 



:n. m.] 



This beautiful species has been reported from as far north as 

 Cayenne, south to Santos, Brazil. The Espirito Santo male has 

 the black areas on the antennae more extensive than in the other 

 specimens.

This species, or at least individuals which we feel compelled to 

 refer to this species, exhibits a most extraordinary amount of 

 variation in structure and, to a certain extent, in coloration. We 

 have before us in addition to the specimens recorded above, indi- 

 viduals of both sex from Sapucay, Puerto Cantera and Alto Parana, 

 Paraguay, and Misiones, Argentina, most of which already have been 

 rreported. These specimens show appreciable variation in the rela- 

 tive width of the head, in the relative size of the ocelli, in the rela- 

 tive length of the tegmina, in the acuteness and degree of develop- 

 ment of the tubercle of the tegmina and in the coloration of the wings 

 and the limbs. The anterior field of the wings may have the colora- 

 tion strongly bicolored, blackish and pea green, or the "ground color 

 pale with the vicinity of the longitudinal veins lined with fuscous; 

 the posterior field of the wings may be unicolored infumate with the 

 principal veins well lined, while in the other extreme the greater 

 portion of the field is pale with the distal section and part of the 

 margin infumate, the veins in the pale area non-infumate. The 

 limbs may be blackish or mummy-brown. At first examination it 

 appears that two distinct species are present, but when all the avail- 

 able material is examined it is found that there is only a partial cor- 

 relation of these characters, one male from Sapucay, for instance, 

 being in every other way characteristic of one of the extremes ana- 

 lyzed above, but having the broad head of the other extreme, while 

 the Peixe Boi individual is in most of its features intermediate be- 

 tween the two types. The genitalic features of all of the specimens 

 seem to be identical for the respective sexes.
