A distinctive and usnally quite marked feature is the broad median 

 shade, and frequently the reniform will be black and form the most 

 conspicuous feature in tlie wing- appearance. 



The distinctive structures of the male anteunaj aud fore legs have 

 been already described so far as essential. 



Bleptina medialis, new species. 



Ground color bluish gray over luteous l)r(nvn, more or less black 

 powdered. Head and thorax concolorous, immaculate. Primaries 

 varying in tint. Basal line traceable m all si)e('imens before me, very 

 distinct and black in some cases. Transverse anterior line nearly 

 upright, irregularly outcurved in the interspaces, variably evident but 

 traceable in all specimens before me. Transverse posterior line slen- 

 der, indistinct, sometimes obsolete, irregular, but hardly <'renulated; 

 in course as a whole outcurved over the cell aud a little incurved 

 inferiorly. Subtermimil line pale, yellowisli, even, a little outcurved 

 centrally, detined by dark marginal lines on both sides or set in a dark 

 terminal shade which extends from the middle of the subtermiual space 

 to the outer margin. A series of black terminal dots, which are some 

 times wanting. ^Median shade line narrow, brownish, nearly parallel 

 with the transverse i)osterior line, not diffuse nor prominent, and some 

 times wanting. Ordinary spots marked in most of the specimens. 

 Orbicular round, pale-dotted centrally, the defining ring brown or 

 blackish and quite broad. Eeniform marked in all tlie specimens, 

 upright, consisting of concolorous or yellowish central line witli a 

 broad black or brownish defining ring. Secondaries smoky to bhu-kish, 

 immaculate in dark forms, in paler examples with an extra median 

 dusky and a pale subtermiual line. Beneath, dull smoky, powdery, 

 with common extra median dusky and subtermiual pale lines. These 

 are always feebly marked and more or less obsolete on the primaries. 



Expanse of wings, 21 to 24 mm. =0.85 to 0.95 inch. 



Habitat. — Semitropical Florida. 



Four specimens are before me, equally divided as to sex. One male 

 was collected by Mr. E. A. vSchwarz, at Cocoa nut Grove, and i.*; from 

 the collection of the United States National Museum; the others were 

 collected by Mr. Palm in the same region, but the exact locality I do 

 not have. 



The species is a well-marked one in the antennal structure of the 

 male, and three of the four specimens are distinct by the dusk}- immac- 

 ulate secondaries, by the contrasting blackish outer i)ortion of ])ri 

 maries, and bj- the pale centered orbicular. The fourth specimen, a 

 female, resembles some forms of B. caradrinaiis so closely as to make 

 doubt i)ossible. It is smaller, however, and the vestiture is closer, more 

 smooth, the median shade not at all traceable, and the transverse poste- 

 rior line is not crenulated. The species will ]>robably be found to 

 extend into the West Indies.
