bv the oblong space on the inner third of the wing, succeeded by a triangular 

 enclosure on the inner edge ol the wing. 



The largest specimen comes from Philadelphia, li differs from all the 

 other specimens which 1 have carefully examined in (he triangular space 

 being merged in with the oblong space, the converging lines being separated 

 \)\ a considerable space. 



It is possible that there are two broods in Texas. 



I am inclined to regard this Philadelphian specimen, and others with the 

 intra- and extradiscal lines farther apart than usual, as GrueneVs Cidaria 

 gracilineata (see my plate 8, fig. 54). His description agrees well with these 

 specimens. There are, however, others connecting the two forms, so that 

 gracilineata may denote a race or strain, but scarcely a variety. 



Larva. — I have found the caterpillars varying from green to brown ; 

 and, while diversilineata feeds on the grape-vine and Ampelopsis, the graci- 

 lineata is said by Guenee to feed on a Vaccinia in, on which diversilineata may 

 yet occur. Mr. W. Saunders, of London, Canada, has found the larva feeding 

 on the woodbine. According to his notes, "the body above is dark-brown, 

 with a slightly- red dish tint, and patches of a darker shade along the dorsal 

 region, being the color of the twigs of its food-plant. It remains in the pupa 

 state about a week." I have found both brown and green specimens feeding 

 on the leaves of the grape-vine in midsummer. The larva is long and very 

 slender, smooth, cylindrical, and in its general shape agrees with the diag- 

 nosis of the genus given by M. Guenee. I regret that I did not draw up a 

 detailed description of the larva. 



Pupa. — The following description is taken from a well-preserved cast 

 skin in the Harris Collection : Body rather stout ; wing-covers reaching to 

 the seventh abdominal ring, counting from t lie end ; the tip is acutely conical; 

 anal spine large, acute, much flattened from above downward : bearing two 

 large, curved spines, with two much smaller, curved, basal spines; abdomen 

 with scattered, acute spinules arising from minute, black tubercles; pale 

 ash, minutely speckled with darker fine points, with a dark dorsal line 

 extending from the head to the end of the anal spine. Length, 0.55 inch. 



Egg. — Cylindrical, much rounded and fuller at the posterior than at the 

 anterior end, which is truncated and contracted, with a swollen rim; white 

 with the surface granulated.
