the genera Eudryas and Ciris. The present species recalls in this re- 

 spect quite strongly 0. wilsonii, although a much smaller insect. 



PHALAENIDAE. 



FIDONIA, Treiis. 

 Fidonia fimetaria, n. sp. ( Plate 2, figs. S4, 85, 'J, ; Rfi, 9 . 1 



S 9 . — Dark brown and ochreous. Upper surface of wings dark 

 brown ; costa of primaries sprinkled with ochreous scales and an ante 

 apical ochreous transverse band broadly incepted on costal region. 

 Fringes pale interrupted with brown. Female paler than the male 

 and showing a terminal macular band at apices of primaries. Beneath 

 the secondaries are dark ochreous tratisversely banded with whitish 

 nacreous. At base there are irregular sp:)ts. Beyond, an interrupted 

 ante median band ; a second, post median, is continued and there is a 

 regular series of ovate neatly detiiied intersp:tcal spots. These bands 

 of nacreous scales are all relatively narrow and strongly limited by 

 dark scales. Primaries dark with a terminal series of spots inaugu- 

 rated at apices and the inception of the ante apical band marked ou 

 costal region. Body brown sprinkled with ochreous beneath. Abdo- 

 men above ochreous, with segmentary marks more apparent in the fe- 

 male. Exj}. 12 to 24 mm. 



Habitat. — Texas (Belfrage). 



Closely resembles the European F. fasciolaria, IIi(/n. sp. {Fid. cre- 

 braria, Auct.) and represents the genus typically in our fauna. Our 

 species seems a little smaller, the female darker. Ou the undersurface 

 of the secondaries the ground tint is brighter and the comparatively 

 narrow well defined pale bauds contrast strongly with the wide diffuse 

 and irregular white marking of T. fasciolaria. Our species has the 

 thoracic parts beneath ochreous not whitish. Finally the regular ser- 

 ies of terminal ovate interspacal spots on the hind wings beneath in F. 

 fimetaria, are replaced by a vague interrupted terminal band in F. 

 fasciolaria, in which latter species the ante median band is not de- 

 fined, while the % antennae in F. fimetaria are decidedly more .plum- 

 ose. 



Eleven specimens have been sent us from Texas by M. Belfrage, 

 taken in the month of August.
