11. sputjitor. The thorax is brown, concolorous with the wings, 

 williout marks; beneath, similar to II. sputator, but the color is 

 everywliere lif^lit lirown, not bhickisli brown. Both species are un- 

 doubtedly typical Uadenas, and very closely allied. Mr. Walker's 

 generic references are therefore inexplicable, Avhile neither species 

 can be recognized with certainty by the descriptions in the British 

 Museum Lists. The form described above under a necessarily new 

 name bears a resemblance to the European Alopecurus, Engramclle, 

 fig. 373, b, not «; 1 have, liowever, both sexes of our American 

 species, corresponding with each other in color. On the other 

 hand Hadena dubitans resembles, but more distantly, Engramelle's 

 fig. 373, a. The typical Hadena rurea, is represented in the collec- 

 tion of this Society by a New York specimen. 



2. Ipimorpha pleonectusa, G'/'o^e. 



(5 . — This species is allied to the European suhtusa. It ditfers by 

 its larger size and different tint. Instead of olivaceous, it has a faded, 

 dusky, warm testaceous hue. The ornamentation is similar, but the 

 claviform spot is proportionally larger in the American species, in, 

 which it equals the orbicular. The subterminal line differs by being 

 outwardly pale-lined, and notably more jagged and distinct than in 

 the European congener. Beneath, the usual lines are not perceptible. 

 A longer description is not necessary ; the different tone of the deli- 

 cate evenly diffused tint of the nearly concolorous species (with its 

 even pale median lines, and large pale-circled concolorous ordinary 

 spots), its larger size and the differences in the markings detailed 

 above, easily separating it from the European subtusa,^\\i\\^\\\\c\\ it 

 coincides in the shape of the wings and the presence of the clavi- 

 form spot, the latter absent in retiisa.

 Varies in the color of the reniform spot, which is sometimes white 

 (as I have described it), sometimes fulvous (as Guenee describes it).
