which aro white spots or tufts of hairs frequently connected by 

 tranverse curved lines of the same nature. The sides are 

 irregularly marked and streaked with black ; the under side 

 being yellowish brown, slightly tinged with red, and clothed with 

 yellow-grey pubescence. 



A very active, pretty, and distinct species ; abundant on the 

 sand hills near Southport, Lancashire, and also received from 

 Scotland. It runs in sunshine only, disappearing instantly on 

 the obscuration of the sun's rays. 



The egg-sac is peculiar, being of a pale flesh-coloured-pink 

 hue. 



TARENTULA ACULEATA. 



Araneus aculeatus, Clerck., Thorell, Syn. Europ. Spiders » 



p. 323-8. 

 Tarentula aouleata, Clerck., Cambr., Entomologist 1877, p. 205, 

 and Ann. and Mag., N. H., s. 5, 1., p. 124. 



Length of the male nearly 4J lines ; female rather larger. 



This spider is exceedingly closely allied to Tarentula pulverulenta, 

 Clk. (p. 364). It is, however, considerably larger, and the legs 

 are proportionately longer ; in the present spider those of the 

 fourth pair are (according to Dr. Thorell, I.e.) nearly three-and- 

 a-half times as long as the cephalo-thorax, while in Tarentula 

 pulverulenta they are scarcely three times as long. 



The cephalo-thorax in Tarentula aculeata is little or no 

 longor than the gonual and tibial joints of the fourth pair 

 togcthor, while in tho other species it is distinctly longer. These 

 comparative measurements hold good in several examples I have 

 examined. In the present spider also the abdomen appears to 

 me to be of a much more generally grey hue than that of 

 'Tarentula pulverulenta , and tho central, longitudinal, thoracic band 

 less clearly defined. 



Found at Braemar, Scotland, and also in the Isle of Arran.
