famishes two kinds of hairs, both of which are figured. 

 The entire insect is a good object for a low power. (PI. 

 VII., figs. 2, 3.) 



582. HAIR OF SPIDER (Epeira diademd). These hairs 

 from the legs are fringed with delicate branches, which 

 are spreading in the lower portion and approximate above. 

 (PL VII., fig. 40.) 



583. HAIR OF OX-FLY (Tabanus bovinus). The upper 

 portion of the hairs from the thorax are beset with short 

 fibrils. (PL VII., fig. 49.) 



584. HAIR OF CATERPILLAR (Orgyia antique?). The 

 tufts of dark hairs at the extremity of this common cater- 

 pillar are brush-like at the tips, as shown in the figure, 

 (PL VII., fig. 21.) 



585. HAIR OF TIGER-CATERPILLAR (Ardia cajci). The 

 hairs of the caterpillar of the common tiger-moth are 

 beset with bristly fibrils throughout their length.. 



586. HAIR OF WATER-RAT (Arvicola amphibius). The 

 cellular centre of the larger hairs is occupied by three 

 parallel longitudinal lines of nearly equilateral cells. (PL 

 VII., fig. 42.) 



587. HAIR OF POLECAT (Mustela putorius). Margin 

 of the large hairs serrated. Central portion more distinctly 

 cellular than in the stoat, which the smaller much resemble. 

 (PL VII., fig. 44.) 



588. HAIR OF OTTER (Lutra vulgaris}. Centre of the 

 larger hairs dark and indistinctly cellular. The cells 

 passing across the centre. Margin of small hairs serrated. 

 (PL VII., fig. 45.) 



589. HAIR OF Fox (Vulpes vulgaris). Transparent, 

 except the centre, which is occupied by a row of distinct 

 cells, shorter than broad in the larger hairs, and nearly 

 equal in the smaller. (PL VII., fig. 46.) 



590. HAIR OF STOAT (Mustela ermined). Largest hairs 

 with a dark centre, the cells of which can scarcely be dis- 

 tinguished, the smaller serrated at the margin and the 

 centre with a single series of equilateral cells. (PL VII., 



fig- 47-) 



591. HAIR OF FALLOW-DEER (Datita vulgaris). Large!
