4 ENTOMOLOGICAL NEWS [Jan., 'll 



Our first specimens of pseudocellus were taken on June 7th, 

 and from then on until July loth it was on the wing in abun- 

 dance. Ccllus first appeared about the middle of June, but was 

 not plentiful until July. We at once noted that there were 

 two distinct species, and upon careful examination we found 

 very striking characters. The white color at the base of the 

 club in the new species is distinctive, and the undersides of 

 the secondaries are not flecked with the prominent blue metal- 

 lic scales of ccllns. Pseudocellus is also of a considerably 

 smaller size, although varying somewhat. The band of the 

 primaries above in cell us is clear yellow, but orange in pseudo- 

 cellus. The fringes of the upper surface of the secondaries 

 in cellus are yellow, but gray in pseudocellus. The above 

 differences will at once serve to distinguish the two species. 

 Moreover, Dr. William Barnes writes us that, "We have looked 

 over our box of cellus, and find that we have about one hun- 

 dred of the large form and thirty or forty of the smaller. 

 Have series of each and find they are very uniform. There 

 is no doubt but there are two species, and I think without 

 doubt the larger one is cellus, as it agrees quite well with the 

 figure of Boisduval and Leconte, and we can go no further 

 as there is no description." 



Dr. J. McDunnough has very kindly examined and drawn 

 the genitalia of both species, and we find them to be obviously 

 different. We shall deal with this in a future article. He also 

 writes that a specimen of pseudocellus in the Barnes collec- 

 tion bears the label, "W. Va.," while all the others are from 

 Arizona. It is rather astonishing that such a striking species 

 should so long have escaped notice. 



Messrs. E. A. Schwarz and August Busck, of the Bureau of En- 

 tomology, U. S. Department of Agriculture, will leave for Panama in 

 January to search for parasites of the citrus white fly (Aleyrodes 

 citri) and the cotton boll weevil and allied species, and to make a 

 study of the entomological fauna of the canal zone.
