218 FAMILY VI. — COREID^E. 



male with inner mai-gin not dilated, but finely toothed, outer dilation 

 widest at basal third, there angulate and narrowed, thence feebly sinuate 

 and gradually evanescent, disappearing at apical third; of female with 

 inner margin narrowly dilated on basal third, quter one more widely 

 dilated than in male, the dilation narrowed at basal third then slightly 

 widened, again strongly narrowed and obsolete beyond apical third. 

 Length, 18 — 20 mm.; width, 6 — 7 mm. 



Frequent throughout southern Indiana, April 26 — Oct. 16; 

 taken in Marshall County only in the north. Occurs for the 

 most part on the foliage of various shrubs, trees and tall weeds 

 along fence rows, woodland paths, margins of thickets and 

 roadsides. In autumn it often occurs on the flowers of golden- 

 rod, boneset and joe-pye-weed in low moist grounds. When 

 approached it usually rises quickly and flies for some distance 

 to a new resting place. This is the only known species of the 

 genus in the northern states, ranging from New England to 

 Colorado and south to Louisiana, Oklahoma and Texas. It has 

 been recorded from Florida by Uhler and Van Duzee, but there 

 is no definite station record from the State, though it perhaps 

 occurs in the northern counties. While its known range is a 

 wide one, it is nowhere so common as to be injurious. Uhler 

 (1876, 298) says that "in Maryland, it occurs, sometimes in 

 large numbers, on the branches of twigs and bushes along the* 

 borders of oak woods, in September and early October." The 

 males are usually narrower and darker than the females, and 

 freshly moulted specimens often have the antenna? concolorous 

 throughout. 



Uhler (1871, 98; 1878, 381) described from the Harris col- 

 lection a Metapodius instabilis from Pennsylvania and North 

 Carolina and states that the Pennsylvania specimen had been 

 labelled "Anisoscelis prominulus Say Mss." by Say for Harris. 

 Though Uhler does not mention this species in any of his sub- 

 sequent papers or his Check List, Van Duzee includes it as No. 

 241 of his recent Catalogue. Uhler's description fits very well 

 the terminalis of Dallas, and his name has, in my opinion, been 

 properly placed as a synonym of that species by Gibson & 

 Holdridge (1918, 240). It is unlikely that such a frequent 

 and widely distributed undescribed species as terminalis was 

 unknown to Say, but there is no published description in his 

 works which agrees with it, and his manuscript name prominulus 

 was therefore probably based on that species.
