Ripula Tirginaria Hulst. 



This species was described from Florida and I have not any spec- 

 imens before me, yet it seems from the description so near to the 

 Cuban form of Sericoptera mahometaria Herrich-Schaeffer that I doubt 

 if they are distinct. There appear to be two species under this name, 

 one smaller, less strongly marked, the antenn?e of the male heavily 

 pectinated and yellow, which I have referred to as the Cuban form ; 

 the other larger, more strongly marked, the antennae shortly pectinated 

 and dark brown. The latter occurs in Mexico, Peru, Brazil and also 

 in Cuba. This is doubtless the true mahometaria {Seficoptern = Ripula 

 Guen.), which was described from Venezuela. Hulst's measurement* 

 of vh'ginaria agrees with the true mahovietaria ; his description with 

 the Cuban form. Mr. J. A. Grossbeck kindly informs me that the 

 type of vh'ginaria is in the Hulst collection at New Brunswick, N. J., 

 and that the pectinations of the antennae are as long as in vestalis, the 

 markings agreeing with Mexican specimens oi mahovietaria before him 

 in design, but being less strongly developed. R. virginaria, then, 

 will stand as a good species, inhabiting southern Florida and Cuba, 

 where it overlaps the range of R. mahometaria. 



Ripula vestalis Hulst. 



I have two specimens of this species from southern Florida, one 

 collected by myself at Jupiter, Florida, February 21, 1890 ; the other 

 from Cudjo Key, taken by Mr. Pollard. The species has been re- 

 cently redescribed as Gonorthiis bilineata by Mr. Warren (Proc. U. S. 

 Nat. Mus., XXX, 543, 1906). Mr. Warren's type is from French 

 Guiana, but it agrees entirely with the Florida specimens. 



Amphidasys exoticaria, new species. 



Wings brownish gray and pure white ; costal half of basal space brown, dotted 

 with black ; followed by pure white to the inner line ; median space brown, limited 

 by the two lines, black, the inner curved, dentated on median vein, the outer dentated 

 on all the veins, most strongly so on veins 3 and 4 ; a small white discal dot, out- 

 lined in blackish ; a blackish shade paralleling the outer line below vein 2 ; space 

 beyond the outer line white, with two rows of brown blotches partly confluent and a 

 few scattered black irrorations. Hind wings white, irrorated with partly confluent 

 brown dots to the submedian line, which is black, angled on vein 4 ; outer space 

 white, with two rows of brown blotches as on the fore wings, broken between veins 

 3 and 4. Beneath the markings are repeated, somewhat whitish. The top of the 



* The measurement given by Hulst is apparently too large. The type is in frag, 

 ments, but on placing the pieces together the specimen seems no larger than Cuban 

 specimens. Mr. Grossbeck agreed with me.
