 This species seems to be common throughout the Northern and East- 

 ern States and Canada and extends its range westward into Iowa and Colo- 

 rado. Here it mhabits damp swampy spots overgrown with carices where 

 it may be found in greatest abundance during August and September, 

 and more rarely in May when the grass is fresh and green. 



STENOCRANUS LAUTUS, n. sp. 



Form and size of dorsalis nearly. Brownish fuscous marked with a 

 conspicuous pale yellow \ntta from the apex of the head to the tip of the 

 clavus. Front and clypeus deep black with the carinaj pale. Elytra ful- 

 vous brown with the costal and about the two outer apical areoles subhya- 

 line; nervures brown. Inner areoles of the membrane deeper brown or 

 fuscous, and a fuscous cloud may follow the first and second apical nervures. 

 Abdomen black; the lateral margins, narrow edges of the ventral segments, 

 and a medium vitta, pale. Legs slenderly lineated with brown. The de- 

 flexed edge of the pronotum with a brown line. Length 5 mm. 



In most of its characters this species does not differ from dorsalis. It 

 is, Itowever, a little smaller, darker in color, the elytra are darker, especially 

 on the inner half of the membrane, and the outer nervures of the membrane 

 are conspicuously dark. The small apical areole formed by the forking of 

 the second apical nervure is broader and shorter than in dorsalis, and the 

 abdomen is darker in color. 



S. dorsalis is of an almost uniform fulvous yellow color with a paler 

 dorsal line, and the elytra are nearly transparent and marked with one 

 straight longitudinal brown line at apex covering the fourth apical nervure. 

 The wings in both species have a few brown nervures toward their apex. 



From palaetus the present species may be distinguished by the smaller 

 spur, the shorter basal joint of the antennae, and the markings of the 

 elytra which are quite different. 



New York, Virginia. Described from two male examples ; One received 

 from Dr. E. B. Southwick, taken near New York City; the other from the 

 National Museum labeled "Virginia, Oct. 9th, 1881". The latter bears the 

 name which I have adopted for this species. It was applied by Dr. P. R. 

 Uhler but the description was never published.
