well preserved to establish indentity without doubt. Easily recog- 

 nized by its coloration ; the apical transverse spot is frequently 

 interrupted in the middle. It seems to vary but little in size, the 

 above measurements included 14-16 specimens in my collection. 

 On trunk of trees August and September, also attracted to light. 

 Mr. A. Busck — Proc. of the United States Nat. Mus., Vol. xxvii, p. 

 275 — erroneously refers this species to Monopis. 



— — TRYPTODEJIA gen. nov. 



Type sepulchrella. 



Head and face strongly rough haired. Labial palpi cylindrical, 

 rather stout, second joint with apical setae, terminal nearly as long 

 as the second, acuminate. Maxillary palpi plicate, very small. 

 Eyes globose, salient. Antennae nearly as long as the forewing, 

 rather thick, simple. Forewings elliptical lanceolate, 12 veins, all 

 free; large secondary cell ; l 6 simple. Hindwings not as wide as 

 the forewings, lanceolate, costa not retuse, 8 veins, 5 and 6 stemmed, 

 cell open between stem of 5 and 6. Cilia under 2. 



The type of the genus is an obscure looking insect. Its nearest 

 ally is Hijbroma Clem., from which it differs principally by the 

 much longer antennae. In appearance no similarity exists. One 

 species. 



T. sepulchrella n.sp.— PI. I, fig. 3. — Labial palpi dark fuscous externally, 

 apex pale, grayish fuscous within. Maxillary palpi grayish fuscous. Head russet, 

 somewhat brown before the insertion of the antenna?, the latter grayish fuscous, 

 indistinctly annulate with pale. Thorax yellowish, spotted with fuscous, patagia 

 more fuscous, especially in front. Abdomen grayish fuscous. Forewings dark 

 brown, interspersed in varying extent with pale yellow scales, especially so along 

 middle of wing, a large dark brown spot near the base and connected with the 

 costa. a conspicuous spot in middle of disc and one at end of cell, between these 

 two spots the yellowish scales form a pale streak, a spot in middle of fold, from 

 which again extends a pale streak, more or less distinct, to dorsal margin at begin- 

 ing of cilia; the latter ochreous fuscous, speckled with brown scales which form 

 an indistinct dividing line about the middle of their length ; underside fuscous, 

 slightly bronzed. Hindwings grayish fuscous; cilia concolorous. 



Exp. 8.0 mm. ; 0.32 inch. 



Hab. — Maryland (Plummer's Island). 



Taken by Mr. Busck in month of August, who kindly has placed 

 a specimen in my cabinet.
