9 39 mm. Width, pronotum at widest point $ 4.5 mm., 9 8.5 mm. ; 

 elytron at middle $ 4.5 mm., ? 8 mm. ; hind femur at widest point $ 

 4 mm., 9 6.25 mm. 



Besides the holotype and allotype there are two other speci- 

 mens, paratypes A and B, both males with the same data. 

 These exhibit very little divergence from the holotype described 

 above. One shows the antennae somewhat more uniformly 

 dark for the entire length and the color of the insect as a 

 whole slightly more intensive, most noticeable in the darken- 

 ing of the pronotal disk. The size varies slightly, one specimen 

 showing a wing-length of 29 mm., and the other measure- 

 ments in about the same proportion. 



The above type material is in the National Museum, Cata- 

 logue No. 24069. 



The name of the collector of these specimens is not stated, 

 but Mr. Davis informs me it is G. R. Pilate. 



This beautiful red- winged Hippiscus has an elytral macula- 

 tion somewhat similar to that of the macropterous form of 

 Agymnastits in gens, imparting to this more slender insect a 

 superficial resemblance to that rare and more robust species. 



Note on the Genus Cryptonotus (Membracidae, Homop.). 



In his Monograph of the Membracidae (London, 1903), G. B. Buck- 

 ton erected the genus Cryptonotus (p. 43) for the accommodation of a 

 single species Cryptonotus militaris. The species has never been men- 

 tioned in literature since its original description and has apparently not 

 been recognized. No other species have been added to the genus. 



A study of a series of specimens of this species collected by Mr. 11. 

 L. Parish in Iquitos, Peru, Feb. 28, 1920, shows that the insect undoubt- 

 edly belongs in the old genus Mcmbracis. Buckton apparently sepa- 

 rated Cryptonotus from Membracis entirely on the character of the 

 wrinkled and irregular margin of the pronotum, as suggested by the 

 generic name. This condition is, of course, common in cabinet speci- 

 mens of many of the very foliaceous forms of the genus Membracis 

 and cannot be considered a generic or even a specific character, 

 insect is a well-marked and distinct species, but shows no character-, 

 which can be considered of generic value and the species must therefore 

 be placed in the genus Membracis. 



The specific name militans is. however, preoccupied in the .minis 

 Membracis (Fabr. Syst. Rhyng. 15: 39, 1803) so that a new name must 

 be given to Buckton's species. This seems necessary even though the 

 Fahrician species has since been placed in the genus Gelastogonia. 

 therefore propose the name Mcinhnicis buck:- this species to take 



the place of Cryptonotus militans Buckton. \Y. I). FuNKHOUSER, Lex-
