 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.

 pedesque testaeei; tibiis tarsisqne nigro-spinosis. Abdomen supra 

 nigro-terminatum ; appendicibus superioribus ])arvis, brevibus, fimbri-

Hab. America boreali {in Mus. aiict.). 



The whole body, including antennte, palpi, and legs, testaceous ; tibisE 

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

 the abdomen is couically 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 

 hah's, 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 

 tliyridium, 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 Ilampsliire, 

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

 to the European S. hieroglypliicus, striatus, &c., in whicli the wings 

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

 longer than the succeeding cells.
