some specimens whitish. The limit between these two parts of the 

 wing is not very definite and somewhat variable. 



" In the dark costal part are found lighter, yellowish brown, ir- 

 regular patches, one large indistinct at the middle of the costa, one 

 small, rather more distinct costal spot at the beginning of the cilia 

 and in some specimens others not well defined. In the dorsal light 

 part of the wing are ill-defined darker shadings and the veins are 

 indicated darker so as to produce a striate effect. On the fold at 

 the basal one third is a small, nearly black spot which seems to be 

 constant. Likewise is a row of black dots around the apical edge 

 constant in all my specimens. The other markings are more or less 

 varying. 



" Hindwings a little broader than forewings, light bluish fuscous ; 

 cilia yellowish. Abdomen yellow. Legs dark purple, with yellowish 

 white bars on the outside and with tarsal white annulations. Alar 

 expanse 16 to 17 mm." Busck states that hibiscella is quite near 

 ochreostrigella Chambers, but not so conspicuously streaked and with 

 light, dark annulated third joint of labial palpi instead of the uni- 

 formly dark, nearly black terminal joint in ochreostrigella. 



In Dyar's Catalogue (Bull. 52, U. S. N. M., 1902) the distribution 

 of the species is given as District of Columbia. In New Jersey we 

 have found larvae on hibiscus at the following places : Hammonton. 

 July 8; Gibbstown, July 2; Rutherford; Lawrence Sta., Aug. 19; 

 Arlington, Sept. 10; in Smith's List it is recorded only from Angle- 

 sea, May 30, rare (Kf.). 



So far as is known no measures of control have been worked out 

 for this species. If it should prove troublesome in the nursery, 

 spraying with arsenate of lead should be effective against the young 

 larvae before they enter the rolled leaves or feed in other concealed 

 places. Hibernating larvae could be destroyed by burning all dried 

 stems, fallen leaves, etc., during the winter. At one nursery it was 

 noted that raking up and burning the fallen leaves during the fall 

 reduced the infestation the following spring. 



Several specimens of Idechthis gclechice Ash. (identified by R. A. 

 Cushman through the courtesy of Dr. L. O. Howard) were bred from 

 pupae during the latter part of July.
