Insects injurious to fruits . hina, infests it anddestroys a large number of the larvse. No. 137.—The Dark-veined Deilephila. Deilephila chamcenerii Iliirris. This moth very closely resembles the white-lined Deile-phila, No. 136, as will be seen from Fig. 267. It has thesame greenish-olive color, and almost the same stripes and ATTACKING THE LEAVES. 257 markings; but there are diiferences wliieli will enable any onewith ease to separate the two species. Lineata is much thelarger insect, measuring, when its wings are spread, about threeand a half inches, while chamcenerii rarely exceeds two inchesand three-quarters. The central band on the fore wings inchamsenerll is wider and more irregular, the thorax also is lessmarked with white; but the most striking point of differenceis that the veins of the fore wings in lineata are distinctlylined with white, a characteristic wanting in chamsenerii. The mature larva measures from two and a half to threeinches in length. The head is small, dull red, with a black Fig. stripe across the front at base. The body above is deep olive-green, with a polished surface; there is a pale-yellowish linealong the back, terminating at the base of the caudal horn,and on each segment, from the third to the twelfth inclusive,there is a pale-yellow spot on each side, about half-waybetween the dorsal line and the breathing-pores, largest onthe segments from the sixth to the eleventh inclusive; thespot on the twelfth segment is elongated, and, extendingupwards, terminates at the base of the horn. There is a widebut indistinct blackish band across the anterior part of eachsegment, in which the yellow spots are placed, and the sidesof the body below the spots are thickly sprinkled wit!)minute raised yellow dots. The horn is long, curved back-wards, retl, tipped with black, and roughened on its surface: 17 258 INSECTS INJURIOUS TO THE GRAPE. the breathing-pores oval, yellow, and margined with dullblack.
