It is true that the largest and darkest specimen I have ever met with is undoubtedly of this species; but then I have others smaller than even the general run of E. truncatus, and quite light coloured. E. truncatus, Walck.-Blackwall, has been recorded, I believe, as containing one species only--E. lugubris, Sim. There, however, is no doubt but that we have the two in Britain (truncatus, Walck., and lugubris, Simon), and perhaps about equally distributed. I have had types from Mons. Simon, for comparison in deciding which is Walckenaurs' and which is Simon's species. I have met with E. lugubris both at Swanage and Bloxworth, and Dr. A. R. Jackson has also found it in both these localities, as well as in Devonshire. This is the first record of both species as British. Laseola dissimilis, Cambr. Fig. 1.

The female resembles the male in general appearance and characters. The eves in the female sex, however, are more closely grouped together, there being a less interval between the hind-central and hind-lateral eyes, and the central quadrangle is less broad, in proportion, in front compared to the hinder side. The colours in the female were also richer, though this perhaps arose from the male having more recently performed the final moult of its skin, while the female had evidently come to its full colours, the cephalothorax being of a bright orange brown, and the legs of a clearer orange, except the tibia) of the first pair and the tibiae and femora of the first two pairs, which are suffused with a darker yellow brown. The tibia; also of the fourth pair are similarly...
