(dried).—Wings white ; the stronger veins andcross-veins whity-brown ; but the faint traces of finer obso-lescent neuration between the strong veins subopaque subulate continuations decurrent from the forewing, defective, but also white. Cross-veinlets in the mar-ginal area straight and simple, about 27 in number; 9 belowRl and 10 within the sectorial fork. Thorax largely eatenout by cabinet-pests ; mesonotum brown ochreous, intersectedlengthwise by a fine median black suture ; scutum edged atthe sides with whitish; this edging, opposite the fore wings,widened and joined together across the dorsum by a narrow,. Elassoneuria Candida, sp. of wings, with obsolescent interneural reticulation. snbtransverse, slightly retiring whitish band ; prescutum, oneach side of the front margin of the segment, flanked by awhitish spot or streak. Abdomen before oviposition dullgreen, owing to the eggs, but afterwards light drab-colour,with a narrow, black-bordered, medio-dorsal sepia-grey stripefrom the second segment to the tip of the the nerve-ganglia and the nerve-chords for nearlyhalf their length in front of each ganglion are black.
