bottomed pill-boxes, and noticed that those which laid eg<j;s all 

 possessed caudate appendages. The eggs are stalked as iii ('hry- 

 sopido', and the stalk is formed much in the same mannei'. The 

 appendages appear to be of value in helping tlie insect to draw 

 out the stalk to its full length, as they act as a kind of lever to 

 the end of the abdomen. When not in use, thty are folded 

 under it, w ith their tips directed forwards. 



Bearing in mind, then, the foregoing facts, it seems fairly 

 certain that McLachlan was examining fhnalt's, and not males, 

 of hoscelipteron, and that the development of the scales on the 

 wings is confined to the females. 



The scales on the hindAvings of the females of Sp^nnttjiliori'Iln 

 are interspersed with hairs of the usual form. They ai-e small, 

 black, club-shaped, arising from a short stalk, and scarcely 

 flattened at all. Their insertions in the cliitin of the vein do 

 not (bfler, as far as I could see, from the ordinary form of inser- 

 tion of a hair. (Plate xviii., fig.30).

Characters as given in the table above, with the following 

 ailditi«ms. No ocelli, antennte of moderate length (a little less 

 or greater than half the length of the forewing). Coupling ap- 

 paratus of wings absent, except for a rudiment of a jugal pi'ocess. 

 Costal area of forewings exceedingly narrow at base, then widen- 

 ing rapidly, then narrowing towards pterostigma. Costal cross- 

 veins branched; no recurrent, basal, costal veinlet. Pterostigma 

 well developed in all four wings. P>etween Sc and Pi, only one 

 cross-vein, continued downwards on to Cu,. Rs connected to 11 

 by three cross-veins in the forewing (one under the pterostigma, 

 just beyond the fusion of Sc with R), and by two only in the 

 hindwing. Four or five branches of Rs in both wings. M fused 

 basally with R, and with a cross-vein between it and R close to 

 its origin. A single gradate series of cross-veins in the forewing, 

 running parallel to R obliquely through the middle of the wing;
