teplda, for which this species may be mistaken, but the yellowish-white 

 abdomen is rounded, not flattened. The transverse lines are double ; 

 basal half-line dentate, consisting of a black inner line and pale outer 

 shade. Basal space gray; subbasal space wide, blackish. T. a. line 

 with the outer component line most distinct, pale-centred, upright, 

 waved, dentate on submedian vein, running close to orbicular. The 

 claviform spot large, narrowly and incompletely margined with black, 

 with the orbicular whitish-gray; orbicular not closed on median vein, 

 rounded, upright, ringed with black. A square blackish mark connects 

 the claviform with the t. a. line. Eeniform moderate, stained with red- 

 dish or ochreous, annulate with white and with an outer incomplete 

 black ring. T. p. line denticulate opposite cell, with a wider submedian 

 inward lunulation, pale gray, with faint inner black line, followed by a, 

 narrow blackish shade, widening on costa on subterminal space. Sub- 

 terminal space whitish-gray, with a squarish black dash on submedian 

 fold before the line which is near the margin, angulate, cut with black 

 fine streaklets. The narrow terminal space is blackish, with a black 

 interrupted terminal line ; fringes blackish-gray. Outer margin retreat- 

 ing to internal angle below vein 2. Secondaries whitish, with black dis- 

 cal dot, powdered with blackish or fuscous externally, and narrow, me- 

 sial, waved line, accentuated on veins. A distinct, black, terminal line; 

 fringes white. Beneath whitish; fore wings somewhat fuscous; discal 

 dots and faint, common, accentuated, extradiscal line. Expansion, 36 

 millimetres. Centre, N. Y., June {W. W. Hill, esq.). 



Taeache semiopaca, n. sp. 



Allied to caudefacta. White. Thorax, head, and basal half of pri- 

 maries white, immaculate. The median shade-line divides the wing; it 

 is blackish-brown, upright, with a rounded sinus on the cell opposite 

 the spherical, prominent, fuscous, pale-ringed reniform, and a second 

 sinus on submedian fold. The exterior line, somewhat leaden, runs 

 just outside the reniform, which rests on a dark band between the exte- 

 rior and median shade-lines. Terminally the wing is whitish, crossed 

 by an irregular, subterminal, olivaceous-fuscous shading before the sub- 

 terminal line. A faint dark shading on terminal space, a terminal series 

 of black points ; fringes whitish. Hind wings white, touched exteriorly 

 with fuscous. Beneath, hind wings whitish ; fore wings fuscous. Abdo- 

 men white. Expansion, 18 millimetres.

I have received a specimen from Mr. Henry Edwards, which enables 

 me to make the above synonymical reference. The species is so simply
