Morrison.] 124 [ June 16, 



white, even and distinct, bent in the middle, and preceded by a slight 

 bronze shade; in two of the specimens before us, there is in the mid- 

 dle of the median space a large, oblique, somewhat kidney-shaped, 

 intense black spot ; in the other two there is no trace of this spot ; 

 exterior line the same as the interior, acutely angulate above, as in 

 Polenta te^erj Morr., and preceded below by a distinct bronze shade; 

 a blackish triangular space before the apex ; the whitish subterminal 

 line is here distinct, but below it becomes obsolete. Posterior wings 

 uniform olivaceous gray. Beneath gray, on the posterior wings 

 lighter, particularly at the base. 



Hab. Berks Co., Penn., and Leavenworth, Kansas. Collection of 

 Mr. Herman Strecker. 



This, as well as the other species of Schinia, is so strongly marked 

 that it will be quickly recognized if captured. 



Polenta nov. genus. 



We separate this genus from the typical Schiniae, to contain the 

 species described by us as Schinia tepperi. Our type of this species 

 had lost the anterior tibiae ; we supposed that they were armed, as 

 are those of other similar species, but the discovery of fresh speci- 

 mens show that they are plain. This is the principal character on 

 which we separate it generically, as in other structural points there 

 is but little difference, although the markings and general appear- 

 ance are quite different, as will be seen from our original description. 



Tarache obatra nov. sp. 



Expanse, 17 mm. Length of body, 7 mm. 



Closely allied to Tarache candefacta and tenuicula. The thorax 

 and basal space of the anterior wings dark yellow, unmarked. With 

 the exception of the brown terminal space, and a broad yellow costal 

 band, extending from the apex (where it connects with the terminal 

 space) to the middle of the median space, the other portions of the 

 wings are dead black ; the exterior line is strongly projected outward 

 in. the costal light space; below it runs across the black region, and 

 then, as well as above, it is preceded by a more or less distinct brown 

 shade. Posterior wings blackish. Beneath the anterior wings are 

 black, having the base and costal apical portions yellowish ; posterior 

 wings yellowish gray, with traces of a median line and of a terminal 

 gray band. 



Hab. Louisiana. 



The peculiar markings of this insect will at once distinguish it, 

 although its close relation to the species mentioned above is very 

 evident.
