A male from Haulover, Fla., 3 March, 

 though of a slightly smaller size, is not 

 different. One from Haiti also of a 

 similar size differs by the unfinished 

 color of the occiput (it is somewhat 

 li\'id) aiul by the presence of a yellowish 

 tinge in the middle of the hind wings. 

 Three males from Mexico are a very 

 little smaller, but do not differ except 

 that the femora are very dark brownish 

 red, the pterostigma a little darker and 

 there is a yellow tinge in the middle of 

 the hind wings.

 and the two basal segments of the 

 abdomen as in the male ; eyes blue, 

 the hind margin of the occiput on 

 each side yellow ; second segment with 

 a transversal brownish median stripe 

 on each side ; a darker anteapical spot, 

 and two apical blue ones ; abdomen

 3 — 9 with two apical blue spots, seg-

 and segments 4 — 6 with two interme- 

 diate blue spots ; appendages light 

 brown, as long as the two last segments, 

 lanceolate with an elevated keel to the 

 tip, which is not sharply pointed ;
