(Oolaspis ilavida, Say,) which is described further on, and which, 

 though a vegetable feeder, may often be found in the fold of the leaf 

 in company with some shrunken, half-dead worm. 



THE GRAPE-VINE EPIMENIS.— Psychomorpha epimenis, 

 Drury. 



(Lepidoptera Zygsenidae.) 



Under the head of " Blue Caterpillars of the Vine," an account- 

 was given in my last Report (pp. 83-5) of the Pearl Wood Nymph, 

 (Eudryas unio, Huebner), and of what I thought there was good rea- 

 son to believe was its larva, namely, the smaller of the blue caterpil- 

 lars (Fig. 25, a full grown caterpillar; h enlarged side view of one of 

 the joints; c enlarged hump on the 11th joint). I have since been 

 [i'ig- 25.] able to decide defin- U^e- 26 



itely as to the charac- f^llig^ukj^^l 

 ter of this larva, hav- ^3HhK^ 

 ing bred numerous C, vff 1 

 specimens to the per- ' £ ^"^ 



feet state. It turns out to be an en- 

 tirely different insect to what I had conjectured, and produces a beau- 

 tiful little moth (Fig. 26), which may be known to the grape-grower 

 as the Grape-vine Epimenis. 



This moth is most strikingly marked and bears no resemblance 

 whatever to the Pearl Wood Nymph. Its color is deep velvety-black 

 with a broad irregularly lunate white patch across the outer third of 

 the front wings, and a somewhat larger, more regular patch of orange- 

 red or brick-red on the hind wings. The underside is similarly 

 marked, but that of the front wings is less velvety with two additional 

 white spots inside near the costa, the outer one generally, and some- 

 times both of them, connected with the broad white patch. Espe- 

 cially is this the casein the males; the wing appearing to have a 

 large triangular white patch with two quadrate black spots in it con- 

 nected with the costa. The wings are beautifully tinselled with steel- 

 blue, or purplish scales, which form a narrow band near the outer 

 margin of each and appear more or less distinctly on the basal half of 

 the front wings. On the under side the steel-blue is especially con- 

 spicuous on the costa and hind border of the hind wings. In old spe- 

 cimens the scales get much rubbed off and the general color appears 

 duller and more brown. The antennae of the female are thread-like 

 and with alternate black and white scales. Those of the male are 

 beautifully and broadly toothed on two sides, or bi-pectinate, and he 

 is furthermore distinguished from the female by the more uniform
