!gment ; the other tubercles of the usual round form. The tubercles 

 five to the skin a rough and uneven appearance, though in reality it 

 i smooth and glossy. 



Ground-colour dingy greyish-olive, of lighter or darker shades in 

 different specimens ; head a warm brown, marbled with dark sienna- 

 Town, the mandibles also dark sienna-brown ; there are no perceptible 

 orsal, sub-dorsal or spiracular lines ; all the tubercles dark smoky- 

 live. Ventral surface and prolegs uniformly of the ground-colour 

 f the dorsal surface, the anterior-legs polished black. 



I supplied them with fresh grass-roots, but they soon commenced 

 ibernation. 



On March 16th they were all lively again, and apparently in size, 

 olour and markings just as when described in the autumn. On April 

 4th, being full grown, I took a number of them out again for further 

 otes. They had not much altered since described on September 24th, 

 pany of them did not exceed the length then given (five-eighths of 

 n inch), and none did I see over three-quarters of an inch. They 

 vere of the same form, and the most material alteration was in the 

 Tound-colour, which had become browner, many, indeed, having quite 

 Dst the olive tint ; the tubercles had also become browner in accord- 

 nce with the ground-colour, and in the centre of each was a minute 

 'lack spot, from which sprang a short hair. The very minute spiracles 

 Iso black. 



They lived in silken tubes spun close to, or on the earth just 

 bove, or even among the roots of the grasses, and came out to feed 

 i'ith avidity at night. As they ceased feeding they spun firm silken 

 ocoons among the roots of the grass, or very frequently against the 

 ides of the breeding pot, but just below the surface of the soil. The 

 mpa is about three-eighths of an inch long, and of ordinary shape ; it 

 s glossy, fairly plump, and has all the parts clearly defined. Ground- 

 'olour bright yellow-brown, the abdominal divisions darker brown, 

 nd the eye-cases and anal point nearly black. 



I bred a good and beautiful series of imagos, the first not ap- 

 pearing until June 14th, though I had noticed the species on the wing 

 ft large three weeks previously.

 f *ppeared in the newspapers to the effect that creatures "like caterpillars" swarmed 

 i. n some of the mountains in S. Wales to such an extent that they were collected by
