1 have a long series of this species, concerning which Mr. Good 

 wrote me that at the time of capture they appeared to be engaged 

 iu migrating in vast numbers. Only upon the occasion of this migra- 

 tion did hcj observe them during a residence of eight years upon the 

 banks of the Ogove River. Mr. Triraen confirms, after examining 

 specimens I sent him, the opinion 1 had before communicated to 

 him, that this species is the one nassi&A. producta by him.

The description given by Ploetz of his species named Hesperia 

 ealpis is unmistakable, if care be taken to make the comparisons 

 which he suggests. I have also been able to identify his species 

 by means of a copy of tlie figure contained in his ])lates. Per 

 many years I have kept //. calpis apart from the older species named 

 Hesperia ccenira by Ilewitson, but upon examination I discover 

 that every specimen of //. adpis in my collection, several dozens of 

 them, are females, and all of the specimens of typical H. ccenira are 

 males. Furthermore, there is such absolute agreement in the 

 markings aud coloration of the primaries on the underside of the 

 two forms, as to convince me that they are sexes, and I have 

 accordingly united them as above. The female varies in some 

 instances. I have one specimen in which there is a manifest 

 tendency to an enlargement of the white spot on the primaries, 

 80 that the marking approximates more nearly that of the male 

 than is usual.
