24 ANNALS OF SCOTTISH NATURAL HISTORY 



darker, clothed with short gray hairs and some strong bristles at the 

 fore part of the caput ; the two oblique lateral indentations at the 

 junction of the caput and thorax are strong, and marked by a strong 

 black stripe on each side, which is continued on the margin of the 

 fore extremity of the caput, and there is a black patch on either side of 

 the middle of the posterior slope. The thoracic indentation is indi- 

 cated by a blackish longitudinal line, furcate at its fore extremity ; the 

 lateral converging indentations are also indicated by dark brown, 

 dusky lines. Eyes, in normal position; the line formed by those of the 

 posterior pair is rather the longest ; the other two lines are nearly 

 equal. The eyes of the middle line are largest. Legs, moder- 

 ately long, strong, tapering, fairly but not densely clothed with 

 gray and other hairs, and armed with spines ; these are strongest on 

 the legs of the third and fourth pairs. All the tibiae and metatarsi 

 have three pairs in two parallel rows beneath them, excepting the 

 metatarsi of the fourth pair, beneath which the spines are stronger, 

 rather more numerous, and not so symmetrically disposed as on the 

 metatarsi of the first and second pairs. The colour of the legs is of 

 an orange yellow hue ; the coxal, exinguirial, and posterior half of the 

 femoral joints are more or less suffused and marked with black and 

 deep brown ; the other joints are faintly and imperfectly annulated, or 

 marked with brown or blackish. The hairs beneath the tarsi and 

 metatarsi are blackish ; beneath the former they almost amount to a 

 scopula. The Fakes are long and powerful, and of a black hue, with 

 an orange-brown patch in front, and clothed with hairs and bristles. 

 The Maxilla, Labiitm, and Sternum are black, the two former slightly 

 tipped with whitish. Abdomen, oval, of an orange-yellow-brown 

 colour, brightest above, especially towards the fore extremity, 

 clothed with short gray and, thinly, with longer dark hairs. Along 

 the middle of the anterior half the position of the dorsal vessel is 

 indicated by a longitudinal, tapering stripe densely clothed with 

 short white hairs or pubescence, broadest and slightly angularly 

 prominent near the middle, and obtusely pointed at its hinder 

 extremity. The angular prominences and the hinder extremity of 

 this stripe are rather strongly dashed or marked on the margins with 

 black, and following it towards the spinners are 3 to 4 transverse 

 angular lines or small chevrons ending in a black spot on each side ; 

 just above the spinners are two short, pale, whitish yellow, nearly 

 parallel longitudinal lines. The anterior extremity of the abdomen 

 is marked with a short curved black bar on each side of the central 

 white stripe, and the sides have each two nearly straight rows of black 

 spots directed obliquely backwards. The under side is dark brown 

 with a broad, longitudinal, central black-brown band. The genital 

 aperture is not conspicuous, but of characteristic form.
