188 GROTE & ROBINSON. 



of the male shorter, stouter and more lengthily pectinate compared 

 witli Euclea; the pectinations are also more extended, being continued 

 for two-thirds of the antenna from the base. Antennae of the female 

 simple and slender. Labial palpi prominent, exceeding the front, di- 

 varicate and visible from above. " Front" broader than in Euclea. 

 and smoothly scaled. Eyes small and convex. Legs smoothly scaled ; 

 tarsi with short scales, not heavily fringed as in Euclea. Abdomen 

 of the male slight and with a moderate anal tuft; in either sex 

 smoothly scaled and not exceeding the internal margin of the seconda- 

 ries in length. 



Type : Limacodes semifascia, Walker, C. B. M. Lep. Het. p. 1151. 

 (1855). 



This genus is easily distinguished from our North American Coch- 

 liid genera with pectinated antennae by its smooth and close squama- 

 tion, full rounded wings and slight body parts. 



Monoleuca semifascia. (Plate 2, fig. 63 % .) 



Entirely purplish brown, paler beneath. Above, the primaries and 

 thoracic parts are darkest and more intensely colored. On the prima- 

 ries above there is a single prominent silvery white abbreviated band 

 running from the disc to the internal margin at the middle of the 

 wing. This band is distinctly limited, outwardly irregularly and 

 roundedly dentate, and inwardly sinuate. Its width is subject to in- 

 dividual variation. The female is larger and of a brighter brown, 

 with the silvery white band of the primaries above more attenuate. 



Expanse, % 22, $ 24 mil. Length of bodj/, S 9, $ 10 mil. 



Habitat. — West Virginia; Texas. 



(3ur single species is as yet rare in Collections. 



LIMACODES, Latr. 

 Limacodes (lithacodes) rectilinea, u. s. (Plate 2, fig. 62% ). 



Ochreous. Basal half of the primaries evenly and entirely ochreous 

 brown. A median, nearly straight and even transverse dark wood-brown 

 line, edged within by a whitish shade. This is the prominent inner 

 margin of the usual inverse Y-shaped mark. A corresponding line 

 runs from the costa before the apex outwardly, joining the external 

 margin a little below the middle. The ochreous ground color of the 

 wings appears beyond this line over the apex, and forms an inconspi- 

 cuous spot at internal angle. The space included between the lines is 

 paler than the rest of the wing, appearing as if washed with whitish, 

 which latter shade seems to spread outwardly from the median line. 

 Secondaries very dark wood brown, immaculate. Fringes ochreous.
