mity ; in the other this sector divides from, or soon after, its com- 

 mencement, and joins again before the extremity in all the wings, 

 forming along loop). 

 I have two females from Japan. It is a true Grammataulius, 

 and a very strongly marked species. 



Stenophtlax, Kolenati. 



Stenophylax gentilis, nov. sp. S. pallide testaceus. Antennae 

 pedesque testacei ; tibiis tarsisqne nigro-spinosis. Abdomen supra 

 nigro-terminatum ; appendicibus superioribus parvis, brevibus, fimbri- 

 atis, flavis ; app. inf. sursum directis, fimbriatis, flavis, ad apicem nigro- 

 truncatis, dentatis. Alae anticae elongatae, gradatim dilatatae, pallide 

 flavae, immaculatae, subnitidae ; venis flavis ; anastomosibus fuscis ; 

 margine apicali anguste obscuriore ; posticae pallidiores ( <$ ). 

 .Long. corp. 5| lin. ( = 11 mill.); exp. alar. 17 lin. ( = 36 mill.). 

 Hub. America boreali (in Mus. auct.). 



The whole body, including antennae, palpi, and legs, testaceous ; tibiae 

 and tarsi with black spines ; eyes black. The last dorsal segment of 

 the abdomen is conically produced at its apex, which is black and 

 scabrous ; app. sup. small, rounded, concave internally, yellow, and 

 fringed with yellow hairs ; app. intermed. black, truncate (?) ; app. 

 inf. directed upwards, yellow, fringed externally with long yellow 

 hairs, the apex black and truncate, furnished with small teeth. 



Anterior wings elongate, broad, the apex parabolic, nearly uniformly 

 pale yellow, almost nude, and shining, the membrane finely rugulose ; 

 inner margin (area suturalis) deeper yellow ; apical margin narrowly 

 obscure ; veins yellow, the anastomoses fuscescent ; a whitish dot at the 

 thyridium, and another at the arculus. Posterior wings hyaline, 

 tinged with yellow ; anterior margin deeper yellow. 



I have one male, from the "White Mountains of New Hampshire, 

 sent by Mr. H. Edwards, of San Francisco. The species is allied 

 to the European 8. liieroglyphicus, striatus, &c, in which the wings 

 are elongate, and the first apical cell in the anterior pair scarcely 

 longer than the succeeding cells. 



S. ltmbatus, nov. sp. S. rufo-testaceus. Antennae testaceae, fusco- 

 cingulatae. Pedes flavi. Abdomen supra fuscum, infra ochraceum ; 

 segmento ultimo lateraliter productum ; app. sup. parvis, subqua- 

 dratis, flavo-fimbriatis ; app. inf. sursum directis, ad apicem truncatis, 

 extus fimbriis longis instructis ; app; intermed. elongatis, spiniformi- 

 bus, rectis, ad apicem abrupte uncinatis. Alae anticae breves, latae, ad 

 apicem valde obtusae, testaceae ; nebula in cellula thyridii (puncto albo 

 ad thyridium incluso) maculis duabus (una ad basin cellulae apicalis
