AMERICAN LEPIDOPTERA. 121 



TORTEIX, Li7in. 

 Tortrix rileyana, n. s. 



9 . Deep ochreous. Primaries evenly washed with purplish, leaving 

 the fringes and costal edge dark ochreous. The markings take the 

 shape of dark velvety brown rounded maculations, generally of small 

 size and faintly shaded with ochreous on the edges. Three of these 

 subterminally at the base of the wing, subequal, situated interspaceally 

 between the nervures. At a little within the middle of the costa are 

 two fused maculations, the most prominent. Before and beyond these, 

 some faint costal marks. At the extremity of the diseal cell, above me- 

 dian nervure, is the first of a series of maculations, normally four in 

 number but not constant, usually uneven in size. A subterminal 

 series of spots is inaugurated on costa by a large compound shaded 

 maculation. Below this, over the median nervules, sweeps an outwardly 

 rounded series of small approximate dots. Two dots on costa, within 

 and at the apex, and a faint terminal series of minute streaks is shortly 

 discontinued. Secondaries of a lustrous bright deep ochreous; pale 

 along costal margin and darker shaded along internal margin. Be- 

 neath, as are the secondaries above ; both wings immaculate, primaries 

 the darker. B:)dy and appendages concolorous, bright deep ochreous. 

 Antennae simple. 



Expanse^ 28 m.m. Length of hndij^ 10 m.m. 

 "No 234, Larva on Hickory". Two specimens. 

 % . Much smaller than the above, of a paler color. The upper sur- 

 face of primaries not washed with purplish but merely of a darker 

 ochreous than the secondaries. The maculations entirely similar but 

 ferruginous, paler than in the 9 and the slighter costal marks are ob- 

 solete. Abdomen with a moderate anal tuft. Legs at base and under 

 thoracic surface almost whitish. 



Expanse, 20 m.m. Eeiujtli of hoJy^ 6 m.m. 

 "No. 234. Larva on Symphoricarpus." Two specimens. 

 Four specimens received from ]Mr. C. V. Riley, to whom I take 

 pleasure in dedicating the species. Whether the differences noted above 

 are sexual (which I incline to believe) or variations concomitant with 

 the different food plants, I am unable to say and have not sufficient 

 material to decide. The two male specimens agree with each other as 

 do the two of the opposite sex. 



Belongs to Tortrix Linn., as more recently defined by Lederer and 

 Heineman.
