As I have seen only one small colony of this species 

 living in this country, I think it advisable to give 

 Mr. Douglas's original description of the external 

 characters of the adult female. He says (I.e.), 

 " Female dingy pale yellowish-grey ; elongate, narrow, 

 ends broadly rounded, side margins slightly curved 

 out, not recurved ; surface smooth, transversely 

 arched, longitudinally level, semi-cylindric, not cari- 

 nate, a band of fairly dark reticulation along the 

 sides [fig. 11], whence, in some examples, faint dark 

 lines radiate to the margin ; the disc occupied with a 

 long, pale, clear, oval spot; or in some mature 

 specimens the scale [female] is unicolorous yellow- 

 brown, the dorsal pale spot partly or wholly covered, 

 and on the sides minute pale dots in place of reticula- 

 tion. Underside all pale, a broad space all round the 

 insect, a conspicuous blackish eye-spot above each 

 antenna." Antennas (fig. 12) very long and stout, of 

 eight joints, of which the second, third, fourth, and 

 eighth are longest ; formula (2, 3, 4, 5, 8), 1, 6, 7. 

 Legs (fig. 14) a little longer than the antennae ; digi- 

 tules to claw dilated, but more or less suddenly trun- 

 cate. Derm-cells (fig. 13) like those of L. hesperidum, 

 but nearly twice as numerous, which character, to- 

 gether with the very large eight-jointed antennae, 

 readily separate this species from the latter. Mr. 

 Douglas says that the species is " remarkable for its 

 length, narrowness, and semi-cylindric form." This is 

 perfectly true for those individuals which attach them- 

 selves to the comparatively slender stems and branches 

 of the food-plants, but examples which I have seen 

 upon the leaves of the food-plant are, except for their 

 large size, very like L. hesperidum. 

 Long, 4-5*50 mm. ; wide, 2-2-25 mm.
