84 ON SOME NEW AND RARE BRITISH ARACHNIDA. 



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. i. 



Adult female, length i length nearly (2.5 mm.). 



The male of this species was described as new to science in 

 Proc. Dors. N.H. and A.F. Club, Vol. XXVI., p. 58, 1905, PL A, 

 Figs. 6, 7, 8. The female resembles the male in general 

 appearance and characters. The eyes 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 tibiae of the first pair and the tibiae and femora of the 

 first two pairs, which are suffused with a darker yellow brown. 

 The tibiae also of the fourth pair are similarly suffused, most 

 strongly at the fore extremities. The height of the clypeus is 

 about one and a-half times that of the transverse diameter of the 

 ocular area. The caput is furnished with coarse hairs or bristles 

 like the male, but not in so marked a degree, and the fakes 

 (which are weak), with the maxilla, have also numerous bristly 

 hairs at their extremities. 



The abdomen is large round-oval, and very convex also. Its 

 upper side is thickly covered with minute impressed punctures and 

 coarse hairs, and its colour is brownish black. The form of the 

 genital aperture is very characteristic and distinctive. 



One example of the female was found at the beginning of 

 July, 1905, by Dr. A. R. Jackson in the Isle of Portland, in the 

 same locality as that in which the male was found in June, 1904.
