NOTES ON DANAID BUTTERFLIES — CLARK 539 



DANAUS PLEXIPPUS, ?subspecie» 



Speaking of Danaus plexippus as it occurs on the island of Trinidad, 

 British West Indies, William James Kaye said "The specimens from 

 Trinidad are very richly dark coloured and have the marginal band 

 to the hind wing very dark and very little spotted." From this it 

 would appear that Trinidad is inhabited by a local race allied to that 

 on the neighboring island of Tobago. Mr. Kaye's description cer- 

 tainly does not apply to specimens from the mainland in Guiana, which 

 are unusually bright. 



The only specimen at hand from Trinidad represents Z>. p. plexippu-i 

 and not the form mentioned by Mr, Kaye. 



DANAUS PLEXIPPUS PORTORICENSIS, new subspecies 



Plate 72, Figures 3, 4 



Diagnosis. — Eesembling D. p. nhegalippe from the Guianas but 

 smaller, the fore wing less than 45 mm. long; pair of white spots just 

 beyond the end of the cell in the fore wing absent ; two preapical spots 

 small and pale yellowish; no white spots in the black border of the 

 hind wing. 



Range. — Known only from the island of Puerto Rico. 



Type. — Ciales, north-central Puerto Rico, collected by C. G. Ander- 

 son and A. S. Mills, of the United States Bureau of Entomology and 

 Plant Quarantine, December 5, 1933, $ (U.S.N.M. No. 53527). 



Additional specimen examined. — No data, $ ; received from the 

 Brooklyn Museum. 



Remarks. — The small size, absence of the two light spots beyond the 

 end of the cell, and absence of white spots in the border of the hind 

 wing give this form a very distinctive appearance. It is, of course, 

 possible that it may prove to be merely an abnormally marked dwarf 

 of Z>. p. megalippe.^ but the fact that the two specimens at hand are quite 

 alike would seem to indicate that it is a valid race. 



A specimen of D. p. w,egalvppe from Puerto Rico also lacks the two 

 white spots beyond the end of the cell of the fore wing, and these are 

 occasionally absent from specimens of Z>. p. plexippus taken in the 

 southeastern United States. 



DANAUS CLEOTHERA Godart 



Plate 74, Figukes 3, 4 



Localities. — Texas: Mediiia River near Castroville, Medina County, 

 collected by C. O. Neumann on October 30, 1938, 5 ; Brownsville, Cam- 

 eron County, collected by Armstrong on November 17, 1933, 5 . 



Notes. — The specimen from near Castroville is a rather small male 

 with the fore wing 39 mm, long. It is rather dark and unusually well
