MaCRISTIS BILINEALIS B. & McD, 



1912, B. & McD., Contr. Nat. Hist. Lep. N. A., I, (5), 30, Dercetis. 



Apparently a Macristis instead of a Dercetis. Neither the "Type 

 S *' nor the "Type 5 " possess an areole, but the "Cotype S " possesses 

 a small areole on one primary, while on the other primary this areole 

 is so flattened that the veins are almost fused. 



Macristis schausi sp. nov. 



Head, collar, thorax, abdomen, and ground color of primaries concolorous, 

 variable, dark brown to yellowish brown ; t. a. and t. p. lines nearly parallel, 

 dark brov.n, bent outwardly below costa, thence strongly oblique inwardly, and 

 somewhat curved, to inner margin; orbicular not present; reniform a small 

 round dot, whitish or jcllowish, without definite bounding line and with no 

 central darker shade ; s. t. line, when present, ochreous, slightly waved, parallel 

 to outer margin, shaded mesially with smoky-brown; a terminal row of small 

 black dots ; fringes concolorous, with a trace of a pale line separating them 

 from the primaries. Secondaries : whitish ; with traces of waved median and 

 subterminal lines ; a broken black terminal line ; and smoky fringes. Beneath : 

 yellowish, tinged with rufous and ochreous, pov.dered and sufifused with fus- 

 cous ; primaries with faint discal dot and median line ; secondaries with a 

 minute intensely black, discal point, and faint blackish median and s. t. shade 

 lines. 



Expanse: $, 12 yi-U mm.; 9, 15-18 mm. 



Closely allied to bilincaUs B. & I\IcD., but; besides being generally 

 smaller and dilTering slightly in palpi, antennae, wing shape, and vesti- 

 ture of the thorax ; the t. p. line of bilinealis is slightly produced to 

 blunt points in the radial-medial region, while the t. p. line of the 

 present species is narrower, clearer cut, and not so produced. The 

 easiest character to use to separate the two is the reniform, which in 

 bilinealis is elongate and possesses a darker central line, while in the 

 present species the reniform is a small round dot possessing no central 

 darker line or shade. 



The authors are indebted to Mr. Schaus for information that this 

 species has not been described from the tropics.
