suggested when similar conditions existing in highland and 

 lower land individuals of Ischnura rambun and /. denti- 

 collis* are recalled. Similarly individuals of Erythrodiplax 

 berenice from the northern Atlantic coast of the United States 

 are larger and more densely veined than those of the coasts 

 of Florida, the West Indies and Central America. f The 

 question needs much further investigation to determine 

 whether a presumably lower temperature is a cause of larger 

 size and denser venation. If this be so, one would expect 

 individuals of S. illotum from British Columbia and the 

 northwestern United States to exceed those of corresponding 

 or lower altitudes in Mexico for example. It is to be hoped 

 that some one with sufficient material will study it from 

 this point of view. A number of the venational features of 

 nigrocreatum given above are not in themselves sufficiently 

 diagnostic to distinguish this form from illotum and its sub- 

 species. They do, however, show the tendency to vary away 

 from the conditions to be found in illotum. 



A New Kricogonia from Cuba (Lep., Rhop.) 



By Chas. T. Ramsden, Guantanamo, Cuba. 



While on a recent visit to the Academy of Natural Sciences 

 of Philadelphia, Dr. Henry Skinner generously called my 

 .attention to specimens of Kricogonia from Guantanamo, 

 Cuba, I had sent him some years before. These differ so 

 much from individuals of other localities that they seem to 

 belong to a new form and may be known as: 



Kricogonia cabrerai n. sp. 



cf Upper side. Primaries: Yellowish white; costa from' insertion of 

 wing to one-quarter of its length is lemon yellow, the remainder slightly 

 tinged with yellowish. 



Secondaries: Same colour as primaries except for a black band 8 mm. 

 long and 3 mm. wide which begins at the costa running toward end of
