-eleven joints, as usual in the genus : the third and fourth joints 

 are very short ; the fifth long, suh-couical, with three or four 

 spiny hau's at the tip : as the third and fourth joints are the 

 thickest, the antenna is somewhat elliptical. Feet absent. 

 Eostrum and mentura entirely wanting. Epidermis covered 

 with very slender hairs, w"hich are sparse on the cephalic and 

 thoracic regions but very numerous on the abdomen, and also 

 with many small, simple, circular spinneret-orifices. Sph-acles 

 sixteen, four of which, on the cephalic region, are very large. 

 Anogenital ring simple, with a tubular organ leading to it, as 

 usual in the genus ; at each side of the ring is a sub-circular 

 scar or orifice of the same dimensions. 



Female of the second stage as described in my last paper 

 (vol. xxii., p. 153). I omitted, however, then to state that 

 from the anogenital ring and tubular organ there springs a long, 

 white, slender filament. This filament is sometimes more than 

 an inch long : it protrudes through the waxy covering, and at 

 the extremity there is often seen a minute bubble of honey- 

 ■dew. The filament is excessively brittle, and pieces broken off 

 are frequently observed on the adjacent twig. At the meta- 

 morphosis the exuviae of this second stage remain in the cavity, 

 and become flattened and disc-like : on breaking open the 

 waxy test in late autumn, when the eggs have been laid, this 

 pupal skin is usually the first object visible, covering the eggs, 

 and, as the adult femaJe (as stated above) has shrivelled up, 

 the skin may be at first mistaken for the adult, but the 

 presence of the very large rostrum and mentum at once shows 

 the real state of the case. The filament already mentioned 

 frequently remains protruding, and is found to be attached to 

 this pupal skin. 



Larvr red, elongated, sub-elliptical, tapering somewhat 

 posteriorly, active, sparsely covered with thin white cotton ; 

 length about gVin. Antennae of six joints — the first five 

 cyhndrical, sub-equal ; the sixth very large, ovate. Feet with 

 rather thick femora and tibite ; tibia shorter than tarsus ; 

 claw slender, with a tooth on the inner margin ; no tarsal 

 digitules, the lower pair long, fine, wath a slightly-dilated tip. 

 Mentum large, conical, triarticulate, with a few" hairs at the 

 tip. Epidermis bearing many simple circular spinneret- 

 orifices, which are most numerous in a circular patch at the 

 abdominal extremity, with the usual tubular organ bearing 

 tlu-ee rings of glands ; at the extremity are two very small 

 anal tubercles, each bearing a long seta, and from the "tubular 

 organ there protrudes betvreen the tubercles a thickish pencil 

 of white cotton. 



Male unknown.
