This very distinct species was first described by Mr. Morrison as 

 a local form of chandlerl, and Mr. Grote for some time was not in- 

 clined to grant it even varietal rank. In his later papers he queries 

 its being a variety and in the new Check List it appears as a good 

 species. In this latter opinion Mr. Grote is correct. The species is 

 readily separated by the ground color, which is constant, by the fact 

 that the ordinary spots are not confluent, by the indefinite band of 

 secondaries, and lastly by the very different genitalia. The harpes 

 are not unlike that of chandleri, but the clasper is rather short, sides 

 parallel to near tip, where it abruptly narrows from inner side and 

 terminates in a moderately long, curved, acute spur. Mr. Tepper 

 has found the specimens in crevices of bath-houses along the beach 

 of Long Island. It is not common.

Head, thorax and primaries ash-gray, variable in depth. Primaries with the 

 transverse line visible only on costa, else obsolete; a narrow variably distinct 

 black longitudinal basal line reaching into the elongate claviform which is nar- 

 rowly black ringed and may be either concolorons or distinctly paler than the 

 ground color. Orbicular elongate, somewhat dilated outwardly or clavate, not 

 reaching the reniform in the specimens before me. Reniform moderate, normal 

 in form, more or less distinctly, but always very narrowly black ringed, concol- 

 orons, or slightly paler, sometimes superiorly only. S. t. line pale, interrupted, 

 more or less punctiform, preceded by a more or less evident series of black or 

 fuscous sagittate marks indistinctly pale ringed. No evident terminal lunules. 

 Fringes fuscous, cut with pale ; the veins are more or less marked with black 

 scales. Secondaries smoky fuscous, paler basally; in some specimens whitish, 

 with an indefinite smoky outer border. Beneath, primaries smoky basally and 

 on disc, whitish outwardly. Secondaries paler, white, powdery with a variably 

 distinct discal spot and a punctiform outer line. Collar with base and tips dusky, 

 centrally paler. Expands 1.30 — 1.40 inches; 33- -35 mm.

This species varies somewhat in the depth of the gray ground 

 color and consequent distinctness of maculation, but not otherwi.se. 

 The characters given by Mr. Grote to separate curvicolUs from major, 

 are evanescent and a comparison of types proves them identical. It 

 is regrettable that the name curvicolUs cannot be retained since it 

 refers to a character more or less marked in most specimens, wliile 

 major conveys an erroneous impression of size. I regret that the 

 genitalia could not be well studied. The harpes are very like those 

 of 0. glennyi, while the clasper, which was detached and broken,
