The only addition to Mr. Blandford's list, except the 

 Pericopid moth, is Mechanitis lycidice, Bates, which this 

 authority places in an intermediate position between the 

 above North Central-American and a South Central- 

 American (Costa Rica to Panama) combination. He 

 includes four other species in this intermediate position, 

 but these are so much nearer to the southern combination 

 that no mention of them is necessary here. M. lycidice, 

 however, is extremely variable, and, in Guatemalan speci- 

 mens, the black bar of the hind-wmg is as a rule well 

 developed, as in the northern Mlillerian association. On 

 the other hand, the absence of this feature in many Costa 

 Rican examples permits their introduction into the 

 southern combination.
