March, 1906.] Smith : New NOCTUID/E. 25 



" It is closely related to the preceding \rivulosa~\ while easily separated 

 from it." The characteristic feature in which the species differs from 

 all its congeners is that there is no complete median space and there 

 are no median lines. From the costa a t. a. line starts normally, but 

 instead of crossing the wing it forms a segment of a circle, reaching 

 the costa again at the place of the t. p. line. On the inner margin a 

 similar mark occurs and between the two segments the ground color 

 extends through the center of the wing. 



On the occasion of a visit to Boston in September, 1905, I had 

 opportunity to look over the very interesting collection of Mr. H. H. 

 Newcomb and found to my delight an example of Schinia const ricta, 

 though not exactly typical. It came from New York in the Emily L. 

 Morton collection, was marked New Windsor, 22, VII, '91, and was 

 a unique. It had the lines marked as in the type ; but the dark shad- 

 ing did not extend across the median space and which was quite obvi- 

 ous throughout. The relationship to rivulosa was now so clear that I 

 determined we had only an aberration to deal with and looked over 

 my own specimens, finding a clear tendency to narrow the space between 

 the median lines. One example had them so nearly approximated 

 that the space was all but divided and was a perfect intermediate 

 between the normal form and the New Windsor specimen. 



Constricta must, therefore, in future rank as an aberrational form 

 of rivulosa and not as a distinct species. The original type is from 

 North Carolina and as the second specimen is from New York, the 

 aberration may occur anywhere within the range of the species. 



Schinia accessa, new species. 



Ground color silvery white, overlaid by pale olive green, so that only the lines 

 show the ground. Head, edge of collar and patagia and disc of thorax white marked. 

 Abdomen whitish. Primaries with the transverse lines in the form of broad, oblique 

 white bands. Basal space shaded with white above and below the median vein. T. 

 a. line with a long outward tooth on the cell extending almost to reniform, inwardly 

 oblique below. The band is inwardly bounded by a darker edging, outwardly with- 

 out a sharp defining edge between the white and olive. T. p. line very oblique with 

 a little outcurve over cell and a little indrawing below ; inwardly indefined, outwardly 

 edged by black scales which may form spots. S. t. line narrower, white, even, close 

 to and parallel with outer margin ; fringe white. The reniform is in the form of an 

 oblique, elongate lunule with the margins black, the center concolorous. Secon- 

 daries white, with a more or less distinct outer blackish band and a blackish discal 

 lunule. Beneath, primaries whitish, with the maculation of upper side incompletely 

 reproduced, the reniform black filled and the orbicular present as a black spot. 

 Secondaries also with markings of upper side feebly indicated.
