"Pale grey. At base of primaries is a deep black transverse band, extending 

 quite across the wing. At internal angle and apex are distinct black lines 

 forming circles, the enclosed spaces being dotted with brownish black scales, and 

 there are also several irregular black dashes on the rest of the wing. The sec- 

 ondaries are pale grey, with faint black reticulations. The under side has the 

 markings reepated, but a little more faintly. Thorax and abdomen grey, with 

 blackish mottling. 



Exp. wings 32 mm. Length of body, 15 mm. 



From I male, taken at Jacksonville, Florida, at electric light, by Mrs. A. 

 Trumbull Slosson, to whom I respectfully dedicate it." 



We do not know this species but give the original description of 

 slossoni, as being a little fuller than Walker's. Dr. Dyar has been 

 very successful in clearing up the muddle of synonomy, so long ex- 

 isting between this species and Cossula magnifica, and we would refer 

 for full particulars to his paper (Ent. News, IX, p. 213, 1898). The 

 type locality for basalis has not been known, but in a casual 

 glance through the "Entomological Correspondence of T. W. Harris," 

 ed. by Scudder, 1869, we caine across a letter from Doubleday which 

 has thrown considerable light upon the subject. Referring to a species 

 No. 104, collected by himself at St. John's Blufif, E. F., he remarks 

 that his species is figured by Abbott in soine unpublished drawings he 

 had picked up in London, and presented to Harris. (These plates 

 are now in the possession of the Boston Soc. Nat. Hist, and were seen 

 by Edwards, vide Ent. News, 11, 71, 1891.) Further notes upon the 

 same insect extracted from Doubleday's MSS. are also given on p. 131 

 of the work in question, and leave it without the shadow of a doubt 

 that G. basalis Walk, is the insect in question. As most of Doubleday's 

 specimens came into the possession of the British Museum we can 

 with reasonable probability take it for granted that Walker's type 

 was this very specimen. The locality, East Florida, would thus agree 

 with that of the type of /. slossoni Edw. 



Early stages unknown.
