42 NOLA ALBULAL1S. 



these tubercles (six on a segment) bore little fascicles 

 of hairs, the central hairs considerably longer than the 

 others, that is, generally one or two on each tubercle 

 excessively long; each segment was in itself plump 

 and well defined, and with one transverse subdividing 

 wrinkle very close to the segmental division. 



In colour some were of an almost ivory whiteness, 

 some of a pale flesh tint, others, again, of a bright 

 pinkish- orange colour ; in all there were twin dorsal 

 light greyish lines and velvety black subdorsal marks, 

 or blunt wedge-shaped spots in some commencing on 

 the seventh segment and ending on the eleventh. 



In one instance the lobes of the shining flesh- 

 coloured head were marked with brown, and the plate 

 on the second segment was brown, divided dorsally 

 with the ground colour, the subdorsal black marks 

 commencing faintly and small on segments 4 and 5, 

 stronger on 5, and still stronger on 7, as a right-angled 

 mark, thick at the angle, which extended across the 

 back as far as the dorsal lines, the tubercles on this 

 segment only being rose-pink. The right-angled black 

 marks were continued, but rather thinner, on segments 

 8, 9, 10, and on 11, where they end; they are even 

 thicker on the eleventh than on the seventh, thus 

 forming nearly a bar of black across the beginning of 

 the segment; the legs brown, the ventral prolegs 

 tipped with brown, the fascicles of short hairs whitish, 

 the longer hairs dark brown. The dorsal pair of 

 tubercles on the eighth, ninth, and tenth segments 

 finely outlined in part with black. 



This last individual I watched at intervals con- 

 structing its curious cocoon, which is made on a dry 

 grass stem of the thickness of a duck-quill ; it com- 

 menced by gnawing in a line downwards at the longi- 

 tudinal fibrous exterior of the stem, loosening it in a 

 long thread, then another and another thread, and so 

 on in succession until a great number of small threads 

 were loosened of the length of nearly an inch, but not 

 detached as yet. This gnawing was patiently and
