species {lucasi Sm., tctragona Wlk.) we should not be surprised to 

 find our reference correct ; the S resembles lanceolata Sm. but may 

 be distinguished by the basal fovea ; veins 3 and 4 of secondaries are 

 stalked in both sexes. 



CATOCALINAE 



CaENURGIA TRIANGULA sp. HOV. (PI. XV, Fig. 13). 



Head and thorax light purplish-gray ; primaries with the cell, costal region 

 to t. p. line and inner margin purplish gray; reniform narrow, gray, slightly 

 oblique, continued by an oblique broader band of similar color bordered finely 

 with white to a point above anal angle ; the large triangular basal area formed 

 by this band, the cubital vein and vein 1 is deep black brown, its lower margin 

 straight and bordered by a fine whitish line; before reniform and near base 

 of wing just above inner margin slight blackish streaks ; t. p. line white, rigid, 

 from a point on costa before apex to near inner margin where it connects 

 with the upper border line of the pale band joining the reniform with the 

 anal angle thus forming at this point a sharp acute angle ; this angle as far as 

 vein 3 is filled with a triangular patch of black-brown ; between veins 3 and 4 

 from their point of origin to t. p. line is a pale brown shade and between veins 4 

 and 6 in the space between reniform and t. p. line a quadrilateral black-brown 

 patch above which the costal region is purple-gray; s. t. space light brown 

 bordered outwardly by a blackish s. t. line, rigid, parallel to t. p. line and some- 

 what diffuse below apex ; terminal space purplish-gray bordered by a fine dark 

 terminal line ; fringes dusky. Secondaries smoky crossed by a pale postmedian 

 band somewhat bent above anal angle ; a darker subterminal shade and dark 

 terminal line. Beneath light smokj' ochreous with traces of paler postmedian 

 band on both wings. Expanse 28-30 mm.

The species is allied to infcrcalaris Grt. (PI. XV, Fig. 14), but 

 has a much longer triangular black basal patch, the lower margin of 

 which is straight and not curved up near base as in Grote's species ; 

 the paler area separating the two dark patches beyond the reniform 

 is confined to the area between veins 3 and 4 in our species whereas 

 in intercalaris it extends between veins 3 and 5 and is much paler in 

 color ; various other points of distinction may be noted from our illus- 

 trations. We also figure (PI. XV, Fig. 15) diagonalis Dyar which 

 we are not convinced is specifically distinct from intercalaris. 



DoRYODES BiSTRiALis Geycr. (PI. XVII. Figs. 4, 5). 



In sorting over our material of this genus we were struck by the 

 fact that specimens from the Northern Atlantic and New England
