TO PROCEEDINGS OF THE ACADEMY OF 



Form comparatively stout. Anterior wings triangular, with 

 straight costal margin and pointed apices ; in color they are light 

 yellow, with ferruginous markings; the latter are very simple, 

 thej' consist only of broad oblique ferruginous fasciae; the first 

 fascia extends from the inner margin, about one-third of the 

 distance from the base to the inner angle, to the apex, it gradually 

 decreases in breadth and at the apex becomes linear ; the second 

 fascia extends from a point on the inner margin, about two-thirds 

 of the distance from the base to the inner angle, to the apex, it is 

 of nearly equal breadth throughout ; the terminal space is shaded 

 with ferruginous. 



Posterior wings yellowish, immaculate, except a ferruginous 

 dash on the costa just before the apex of the anterior wings. 



Hab. Texas. September 11. 



We refer this little species provisionally to this genus ; it differs 

 from the typical species in the form of the wings and the peculiar 

 character of the markings. We hesitate to found a new genus 

 on a single specimen. 



Tarache crustaria, nov. sp. 



Expanse 26 mm. Length of body 12 mm. 



Habitus and markings of the European T. lucida and T. luc- 

 taosa, and much larger and stouter than our native species, except 

 T. terminimaculata, Grote. 



Eyes naked. Legs long and slender, the tibiae unarmed. 



Front and thorax closely scaled as in the allied species. An- 

 terior wings white, much shaded with black ; a distinct basal 

 black dash, around which the basal space is shaded with blackish; 

 the ordinary spots are reduced to two distinct black dots ; the 

 median space is broad, white, crossed between the spots by a wide 

 blackish band (representing the median shade) extending from 

 the costa to the inner margin ; the terminal and subterminal 

 spaces blackish ; the exterior line is only indicated by the con- 

 trast in color between the spaces ; the subterminal line is white, 

 rivulous, most distinct at the costa and internal angle; it is pre- 

 ceded by two small black blotches, one opposite the cell, the other 

 between the second and third median nervules ; a conspicuous 

 black blotch at the apex ; a series of black dots at the base of the 

 white fringe. Posterior wings black, with indistinct discal dots 

 and with a broad conspicuous white median band, extending from 

 the abdominal margin two-thirds of the distance across the wings.
