H. sputalor. The thorax is brown, concolorous with tlio wings, 

 without marks; beneath, simihxr to H. sputator, but the color is 

 everywhere light brown, not blackish brown. Both species are un- 

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

 generic references are therefore inexplicable, while 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, Engramelle, 

 ilg. 373, h, not «; I have, however, 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 ISTew York specimen. 



2. Ipimorplia pleouectusa, Grote. 



5 . — This species is allied to the European suMusa. It differs 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 lineB, and large pale-circled concolorous ordinary 

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

 above, easily separating it from the European 5?<&/«.sa, with which it 

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

 form spot, the latter absent in retusa.

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

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