ADOP^EOIDES. — ANCYLOXYPHA. 471 



et margine interno quoque fuseis : subtus anticis fulvis, apice flavescenti, striga lata in margine interno a 

 basi angulum analem versus fusca ; posticis fiavis, linea (interdum secunda marginem internum versus) 

 a basi ad marginem externum extendente pallidiore. 

 $ mari similis, sed alis obscurioribus. 



Bab. Mexico 1 2 (mus. Staudinger), Ciudad and Milpas in Durango (Forrer), Amula 

 in Guerrero, Mexico city (H. H. Smith), Puebla, Orizaba (H. J. Ehves), Potrero, 

 Cordova (fide Felder). 



So far as we know, this species is confined to Mexico, whence we possess a consider- 

 able series. The secondaries of some examples show one or two pale longitudinal 

 streaks beneath, while in others these are almost or entirely wanting. The primaries 

 usually have a short transverse blackish line at the end of the cell on the upperside. 

 A. simplex bears a strong superficial resemblance to the European Adopasa linea, but 

 the males have no brand on the primaries. Mr. Rothschild informs us that Felder's- 

 type cannot now be found. For the genitalia of the male, see Tab. XCII. fig. 33. 



2. Adopseoides bistriata, sp. n. (Tab. XCII. fig. 34, 2 .) 



$ . Alis fuseis, squamis fulvis sparsim tectis, linea discocellulari nigrescente : subtus anticis fulvis, marginem 

 internum versus late fuseis ; posticis fuseis, squamis fiavis sparsim tectis, lineis duabus a basi ad marginem 

 externum extendentibus. 



Hab. Mexico. Milpas in Durango (Forrer). 



Of this insect we possess only a single female example. It closely resembles 

 Oarisma poivesheik, but may be readily distinguished from it by the two white 

 longitudinal stripes on the secondaries beneath. The underside of the fringe, moreover, 

 is not bordered internally with white as in that species, and the primaries above have 

 a dark discocellular line. 



Hesperia boeta, ILew.,=Apaustes bilineata, Dognin, from Ecuador, has the secondaries 

 similarly coloured beneath, but we hesitate to place our Mexican female with that 

 species. 



ANCYLOXYPHA. 



Ancyloxypha, Felder, Verh. zool.-bot. Ges. Wien, xii. p. 477 (1862) (part.) ; Watson, P. Z. S. 1893, 

 p. 97. 



The type of this genus is the North- American Hesperia numitor (Fabr.) (=Thymelicus 

 puer, Hiibn.); and Beteropterus arene, Edw. ( = Copceodes myrtis, Edw.), is also an 

 Ancyloxypha. A. melanoneura, Felder, is perfectly congeneric with these, but his 

 A. simplex, A. gracilis, and A. corades belong elsewhere. A. brunnea, Scudd., from 

 Guatemala, as already stated, is a Butleria. 



The antennae are very short, not half the length of the costa, with a moderately 

 stout, blunt club. The palpi have a long, slender, erect third joint. The primaries 

 are short, blunt at the tip ; the cell is much less than two-thirds the length of the 

 costa; the discocellulars are subtransverse, the lower one a little shorter than the
