26 GROTE AND ROBINSON. 



cul. annulate, moderate, ordinary spots: the first, spherical ; the last elon- 

 gate, sub-reniforiu in shape. Below the median nervure, a slight ag- 

 gregation of brown scales. A brown transverse posterior line, slightly 

 trembled below the costa, but running straightly outside the disc, 

 over median nervules, where it is strongly inflected backwards to a 

 point beneath the outer discal spot, running thence straightly to inter- 

 nal margin. A very distinct, deep brown, terminal, regularly inter- 

 rupted line. Fringes, rather long, with a faint linear basal shade on 

 both pair. 



Secondaries, resembling primaries in coloration, thinly scaled. A 

 brown discal spot, and a single brown transverse line, analogous to the 

 transverse posterior line of primaries, and prominently inflected back- 

 wards below the discal cell. A terminal, distinct, macular, brown line 

 as on primaries. Beneath, both wings are paler than above, with the 

 ornamentation of the upper surface more fluently reproduced. 



Expanse, % 9 , 0.90 inch. Length of hodi/, % , 0.45, 9 , 0.30 inch. 



Habitat. — xVtlantic District. (Mass. to Penna. !) 



A very slender, thinly scaled, and delicate species of common oc- 

 currence throughout the Middle States. Diff'ers by its transparent 

 brownish testaceous color and by the stained costal edge. Specimens 

 occur in which the transverse anterior line of the primaries becomes 

 obsolete along its backward inflection ; the primaries then appear to be 

 crossed by tlLi-ec transverse lines. The obsolescence of this line at 

 this point is not an unusual occurrence in other species of the genus 

 and family. 



Botys adipaloides, n. sp. (Plate 2, fig. 19, 9 )• 



% 9 • Size, moderate. Head, prothorax and palpi, obscure brownish, 

 beneath, white. Thorax, above, shading posteriorly to yellowish. Ab- 

 domen, above, brownish; tlie seg ueuts are edged with whitish scales, 

 basally mixed with yellow scales above. Beneath, the abdomen, tho- 

 racic parts and legs are obscure whitish, silky. 



Wings, shaped nearly as in Botys adipalis, Z-lIcr, as illustrated by 

 Lederer. Primaries arched before apices, on costa. External margin 

 sinuate, retreating within the produced apices, thence outwardly 

 rounded at extremities of median nervules. Secondaries with the 

 apices well produced, the external margin receding immediately 

 below them, thence evenly rounded to anal angle, lioth primaries 

 and secondaries are rather bright clear yellow. All the markings are 

 of an obscure purplish stone color, l^rimaries, dark dull brownisli 

 along costa. An inner transverse narrow line. Two large (quadrate
