DAMiEDS CLAVIPES. 423 



Distribution. — I have only found tliis species in the 

 thatch of an old roof near the Land's End, Cornwall. 

 The similarity of habitat and of the nymphs raises a 

 suspicion that this species is only a variety of D. 

 tecticola, but the different length of legs, and the 

 entirely different pseudo-stigmatic organs, seem to 

 preclude their being so treated. 



DAMJ3US CLAVIPES* (Herm.). PI. XXXVIII ; PL D, figs. 



6, 7; PI. E, fig. 5; 

 PI. G, fig. 12. 



Notaspis clavipes, Herm. P. 88, pi. iv, fig. 7. 

 Damceus nodipes, Koch. Heft 30, fig. 6. 



— concolor, — Heft 36, fig. 6 (?). 



— auritus, Nic. P. 462, pi. viii, fig. 3. 



Belba geniculata, Can. e Fan., p. 33 (this applies also to D. 



geniculatus). 

 Oppia glaucina, Koch. Heft 3, fig. 9. Probably nymph of this 

 species. 



Average length about 1'05 mm. 



Average breadth about '70 mm. 



Average length of legs (first pair) about 1'31 mm. 



Average length of legs (second pair) about l"14mm. 



Average length of legs (third pair) about 1*25 mm. 



Average length of legs (fourth pair) about 1*80 mm. 



This species has doubtless been confused with D. 

 geniculatus by almost all of the earlier, and even by 

 some of the later writers (see observations heading 

 the description of D. geniculatus). It is nevertheless 

 very distinct, having the joints of the legs much longer, 

 and more slender, the peduncular portion of each 

 joint being longer, and the club shorter and more 

 distinctly marked off. The whole creature is smaller 

 and slighter, and there are other differences. 



Colour. — When the adult has lately emerged it shows 

 a purplish bloom, and is not dark; older specimens 



* Clava, a club ; pes, a foot.
