tlins suspended, begins twirling round and round, at first . 

 slowly, and afterwards with great rapidity, — a feat I have 

 sometimes seen performed by a sing when suspended by a 

 thread of slime exuded from its own body. Head manifestly 

 wider tlian the segments immediately following, prone, slightly 

 notclied on the crown, which rises in a very marked manner 

 above that part of the back which is immediately behind the 

 head-c the body tapers gradually to the 11th segment, and 

 thence more suddenly tapers in a point ; this ])oint ap- 

 pears to be the anal flap ; on the 4th segment are two closely 

 approximate warts placed transversely : every part of the 

 body is beset with minor warts, each of which emits a hair. 

 Colour of the head pale reddish brown, reticulated with 

 darker brown ; body having the dorsal surface dark umber- 

 brown ; there is a pale, almost white, narrow stripe on each 

 side, commencing close to the head and passing obliquely 

 towards the back, where it unites with a medio-dorsal white 

 V-shaped mark on the 6th segment ; the same marking is 

 continued as a pale brown shuttle-shaped dorsal stripe on 

 the 7th, 8th, 9th and 10th segments, and is intersected 

 throughout by an extremely narrow dark median line ; there 

 is a conspicuous and elongate pale spot on each side of the 

 11th segment; the dorsal warts on the 4th segment and the 

 anal point are reddish ; belly, legs and claspers very pale, 

 and having a very obscure tinge of green. It descends to 

 the ground in September, and changes to a pupa on the sur- 

 face of the eaith or among the leaves, in a slight Aveb. The 

 pupa is brown, the wing-cases having a greenish tinge. —

Description of the Larva of Bryophila glandifera. — The 

 eggs are laid in September, on those flat lichens which so 

 commonly cover the surface of stones used in building walls, 

 bridges, houses, churches, &c. : they are white, and in con- 

 finement are arranged in a perfectly straight line ; they are 

 hatched in October, the little larvae on leaving the egg-shell 

 being perfectly black and very hairy : they appear to hyber- 

 nate in crevices of the stone while still extremely small, but 

 in the following March or February, or even the end of 

 January if the weather happen to be wet and njild, they 

 again begin to feed : each then constructs a house for him- 

 self, a kind of cocoon made of silk and particles of earth,
