The type-specimen of E. Westringii (dried), the only full-grown 

 female of this species that I have ever seen, so closely resembles 

 E. alpica ?, that I can only distinguish it by the colour of the ab- 

 domen. This specimen is certainly somewhat larger than the examples 

 of E. cucurbitina usually met with in Sweden; the cephalothorax is 

 however not more than 3 millim. (the same measure is given by 

 L. Koch as that of E. cucurbitina and E. alpica), not longer than 

 patella + tibia of the 4:th pair. The cephalothorax is without dark 

 lateral bands; the legs are brownish yellow, the tibiae, metatarsi and 

 tarsi brown at the apex. The abdomen is somewhat drawn out in 

 the middle, in front, not uniformly and' semi-circularly rounded; it 

 has on the upper side, behind, three pairs of black points; its sides 

 are red, as is also the region immediately above the anus; the back 

 exhibits a greenish white band on each side; within these bands the 

 back is surrounded by two greenish bands, which at the posterior 

 extremity, where they meet, become reddish and unite with the red 

 spot above the anus. Within these bands again the back is occu- 

 pied by a narrowly egg-shaped or lanceolate, greenish white area, 

 which is divided into two by a middle band greenish in front and 

 reddish behind, with irregular edges and tapering backwards to a 

 line. The belly is greenish in front, with a reddish shade behind, 

 and shows indications of 4 large yellowish spots arranged in a square. 

 The scapus of the vulva seems to be longer than in E. cucurbitina, 

 furnished with bristles at the base, in front, just as in E. alpica. — 

 Dr L. Koch informs me, that he has lately in the neighbourhood 

 of Nvirnberg captured three full-grown female specimens of E. We- 

 stringii. 



A full-grown (dried) cf , captured here at Upsala by Dr Hag- 

 lund, which I refer to E. Westringii, resembles the female as re- 

 gards the colour of the abdomen above and at the sides; there are 

 however four pairs of black points on the back, behind; the legs 

 have a little stronger shade of red than in the female, and the thighs 

 are somewhat paler at the base: in other respects the legs have the 

 same colour as in the The cephalothorax is destitute of dark 

 lateral bands. The spines on the under side of the thighs are very 

 long, 8 in a row on the anterior pairs: these rows reach quite to 

 the apices of the thighs on the four posterior legs also, and are not 

 interrupted. The forward-curved process above at the base of the 

 lamina, which in E. cucurbitina and E. alpica terminates in a but- 

 ton-like knob, is here at the extremity bent down almost at a right
