NEW AND RARE BRITISH SPIDERS. 2) 



four centrals form a quadrangle, whose length is a little greater 

 than its width, and its fore side shortest, but not greatly so. 



Legs, moderately long, subequal, rather slender (4, i, 2, 3), 

 furnished with fine hairs and a few bristles fas in Sintula). 



Falces, long and strong, straight, outer margins, from in 

 front ; convex towards their base, and along the margin are 

 some short minute pale spines. No teeth on the anterior margin 

 of the fang-groove. 



Maxilhe, short, strong, almost straight, nearly parallel, ex- 

 tremities broadest and rounded on the outer side. 



Labium broader at the base than it is high, semi-circular. 



Sternum considerably longer than broad ; shield-shaped. 

 Anterior margin straight, posterior extremity broadly drawn out 

 between the coxae of the hinder legs, and its termination nearly 

 truncate. The interval between these coxae being about equal to 

 two-thirds of the length of the joint. 



Abdomen large, oval, strongly convex above. Spinners normal. 



Eupolis excavatus, sp. n. 



Adult female, length i line. 



Cephalothorax, falces, maxillcc, labium, and sternum, yellow 

 tinged with brown. The cephalothorax has a narrow dark 

 marginal line, the normal converging indentations being indicated 

 with darker lines. 



Legs and palpi pale yellow. 



Abdomen projects greatly over the base of the cephalothorax. 

 Colour yellow brown. Genital process large prominent. Aper- 

 ture of very distinctive and characteristic form. 



This spider was found some years ago at Bloxworth among 

 herbage in a wood, and mistaken for a female of Sintula oblivia, 

 Cambr. ; it is, however, clearly distinct, and the characteristic 

 form and structure of the cephalothorax, maxillae, and sternum 

 appears to require a new genus for its reception. It is allied to 

 Sintula, Sim., as well as to Microneta, Menge, and in the 

 excavated form of the hinder end of the cephalothorax it 

 reminds one of Auletta, Cambr.
