cate at base, 2 and 3 coincident from the angle, arising nearly 

 opposite 9, 4 and 5 connate, nearer 6, 7 and 8 out of 6, 9 dis- 

 tant, 11 from beyond middle. Hind wings l /2, a little narrower 

 in the male, with anal angle less distinct, termen emarginate, 

 apex produced ; all veins present, 2, 3, 4 and 5 remote, 5 near- 

 est 6, 6 and 7 very short stalked. 



Genotype : Stereomita andropogonis n. sp. 



Allied to Metzncria and Megacraspcdus, but distinguished by 

 the absence of a vein in the fore wing, and by the thickened 

 third segment of the labial palpi. 



Stereomita andropogonis n. sp. 



Head whitish straw-colored, palpi straw-colored, with a dark brown 

 patch near apex of second segment outwardly, and a dark brown an- 

 nulns around middle of third segment. Antennae pale ocherous, with a 

 narrow brown annulus at the base of each segment, and four broader 

 blackish rings on the outer half of the stalk, separated from one another 

 by two or three pale segments. Fore wings pale ochreous, deepest 

 toward apex, and dusted with dark brown scales, most densely on the 

 costal and dorsal margins with a tendency to longitudinal streaking ; at 

 two-thirds of costa, the dusting usually forms two diffuse oblique 

 streaks. Along termen, there is a series of indistinct brownish dots, and 

 opposite extreme apex, in the cilia, a transverse brownish spot. Cilia 

 brownish, except on costa before apex, where they are ocherous. Hind 

 wings pale brown, cilia ocherous, with a faint reddish tinge. Legs 

 ocherous, dusted with brown. Wing expanse : 8.5-9.5 mm. 



Type ( $ ) and 32 paratypes, Miamiville, Clermont County, 

 Ohio, August 19 and 25. Type and paratypes in the writer's 

 collection ; paratypes in the collection of the Academy of Nat- 

 ural Sciences of Philadelphia and in the U. S. National 

 Museum. 



The larvae feed in the inflorescence of Andropogon scoparins 

 (bear-grass.) Their presence is indicated by yellowish 

 patches in the flower spikes. 



The moths are active in early morning and in the evening, 

 flying at the top of the stems around the flower buds, and 

 alighting head downward. During the middle of the clay they 

 rest amongst the basal leaves and are only disturbed with diffi- 

 culty. In markings of wings, palpi and antennae, and in gen- 

 eral appearance when at rest, this insect remarkably resembles 

 some species of Batrachcdra.
