Two other species of this genus have been described from this country : 

 auroreum Uhler and pundijerum Walk., the latter red escribed by Dr. 

 Uhler as aciculatum according to Melichar. 



Genus THIONIA St&l. 



This genus is well represented in Central and South America. Meli- 

 char enumerates the following from this country : 



Thionia simplex Germ. Recorded from Washington, D. C, to Texas. 

 I have taken it in Ohio. 



Thionia elliptica Germ. Recorded from Washington, D. C, to Mis- 

 souri. 



Thionia transversalis Mel. Recorded from "N. Am." 



Thionia hidlata Say. Recorded from New York to Georgia. I have 

 taken it in numbers at Niagara Falls and Gowanda, N. Y., and 

 Mr. Palmer took it in North Carolina. Melichar places Issus 

 conspcrsus Walker as a synonym. 



Thionia ocdlata Mel. Recorded from "N. Am." 



I add the following: 



Thionia producta n. sp. 



Form of naso Fowler, but smaller and less elongated. Vertex much ' 

 longer than broad, almost equally five-sided; the basal portion nearly 

 square, its sides slightly diverging anteriorly, the apical portion pro- 

 duced in an angle a little less than a right angle; sides carinate, hind 

 edge very feebly arcuated, surface flat with a feeble median carina at 

 apex. Front narrow, much longer than the head, a little narrower 

 toward the angulated base; apex deeply emarginate for the reception 

 of the clypeus; the three carinse distinct, acutely converging at base; 

 clypeus long, strongly convex with a prominent median carina. Pro- 

 notum shorter than the vertex, strongly advanced and rounded 

 anteriorly between the eyes, truncated behind, ecarinate, with two 

 impressed points on the disk. j\Iesonotum short, not longer than the 

 pronotum, its sides arcuated. Elytra narrower than in hullata with 

 the costa more angled and the apex more obtusely angled, not obliquely 

 truncated as in that species; venation typical of this genus. Wings 

 deeply cleft. Length 6 mm. 



Color dull testaceous, paler on the abdomen. Vertex and pronotum 

 mostly black with a broad median pale vitta; slender edges of the 

 pronotum and some marks behind the eyes also paler; front much 

 invaded with black on the base, sides and apex; clypeus darker, either 

 side with a few oblique lines; cheeks except at base and apex ivory
