AMERICAN LEPIDOPTERA. 4") 



from which locality Dr. Harvey's type was received. This example 

 agrees very well with the description, and I have no others that 

 agree as closely. Dr. Harvey's specimen was evidently a very 

 fresh example, in which all the contrasts were well defined. Ordin- 

 arily the examples appear much more sordid than mentioned by him. 

 Only three examples all told are before me and none of those are males. 



Hydreecia margiiiicleiis Gn., pi. 2. fig. 34, % genitalia. 



1852.— Gn., Spec. Gen. Noct., i, 123, Gortyna.

1873— Grote, Bull. Buff. Soc. Nat. Sci., i, 111, Hydroecia.

1893.— Smith, Bull. 44 U. S. Nat. Mus., 177, Hydreecia. 

 Ground color a muddy, yellowish red-brown. Head and thorax with a slight 

 purplish shade, the tip of the collar white, a white tuft at the base of the antennae. 

 Primaries not strongly powdered. As a whole the median space is slightly more 

 reddish or yellowish than the rest of the wing, the basal space and all beyond the 

 t. p. line having a purplish or darker red-brown shading. Basal line geminate, 

 extending to the middle of the wing, and between it and the base the wing is 

 white. T. a. line geminate, not strongly marked, very frequently with white 

 scales between the brown defining lines: its course, as usual, a little incurved to 

 the submedian interspace and then strongly outcurved to the margin. T. p. line 

 broadly curved over the cell, then inwardly oblique. It is geminate, the outer 

 portion heavier, purplish and irregular, the inner more brown and with a strong 

 tendency to become luuulate. S. t. line pale, irregular, dentate on the veins, 

 largely defined by a slight difference in shading between the terminal and s. t. 

 spaces. There is a brown terminal line at the base of the fringes, and the apex 

 is yellowish. The median shade line is narrow, usually fairly well defined, a 

 little irregular, somewhat evenly outcurved, or with only a feeble angle below 

 the reniform. Sometimes it is a little lunulate. The ordinary spots are all 

 present; the orbicular' white, moderate in size tending to become triangular, 

 often with a brown central dot, reniform large in every direction, little con- 

 stricted centrally, considerably broader inferiorly than above. There is the 

 usual irregular central luuule, which, in this species, is also white and is com- 

 pletely surrounded by white spots, which arc bounded by the brown veins. The 

 claviform is as usual broken, the two parts similar in size, the upper crossed by a 

 portion of the t. a. line, and as a whole a little smaller than the other. The sec- 

 ondaries are dull, very pale yellowish, with a rosy tinting. There is an outer 

 line visible in some specimens and this may be modified into an s. t. shade. In 

 some instances a smoky lunule is also visible. Beneath pale, shading from yel- 

 lowish to purplish, more or less powdery along the margins, with a rather dis- 

 tinct and narrow outer line, and a more or less evident discal luuule. which is 

 quite frequently absent on the primaries. Expanse 1.50-2 in. ; 27-50 mm.

This is a large species resembling eerrusata in some respects. It 

 is easily distinguished from the other red species by the irregular 

 reniform, which, besides being very large, has the inferior portion 

 much broader than the upper. In this it agrees with appasionata, 

 but that species is smaller, much deeper in color and more powdery.
