KEICOGONIA. 



Kricogonia, Reakirt, Proc. Ent. Soc. Phil. ii. p. 355 \ 



Kricogonia differs both from Gonepteryx and Anteos in having the outer margins of 

 the wings simple and without angular projections. It resembles Gonepteryx in having 

 a smooth costa to the primaries, which, however, is simply curved as in Anteos, and 

 without a concave depression as in Gonepteryx. The secondary male organs differ widely 

 from those of the species of both these genera. The harpagones at the upper end split 

 into two slightly expanding lobes ; near the upper proximal corner proceed two lobes, 

 the upper and smaller one terminating with two or three strong spines directed outwards, 

 the lower and wider one carrying at the end a cluster of spines which are directed 

 upwards. Near the middle of the ventral edge are two long strong spines, and two 

 more near the base. 



Kricogonia consists of two species, one of which is found throughout our country, 

 North-western South America, and some of the Antilles ; the other, so far as we at 

 present know, occurs only in Guatemala and the islands of Haiti and Jamaica.

The conspicuous spot near the apical angle of the secondaries of the male of this 

 species varies very greatly : in some it is an elongate stripe the eighth of an inch 

 wide ; in others it is only just perceptible ; in others, again, it is wholly wanting, the 

 latter precisely resembling the females in external appearance. None of our males 

 from Guatemala show this character, but we find it everywhere else where the species 

 occurs. 



K. lyside does not appear to be a very common insect ; most of our Guatemalan speci- 

 mens were taken in the interior at an altitude of about 3000 feet above the level of the 

 sea, but it is found at a much lower elevation at such places as the Tres Marias Islands 

 and San Pedro.
