104 Rev. F. 0. Pickard-Cambridge on 



Cambridge taken in Dorset ; but all of them were small 

 specimens and absolutely devoid of colour. 



They are very distinct from any other species of Por- 

 rJiomma hitherto taken in England, though closely allied to 

 egeria, Sim., jjronerpina^ Sim., myops, Sim., and others, 

 characterized by the minuteness of the eyes and their great 

 distance apart. 



The single spine on the femora of the first pair in ollongum 

 will distinguish it from any of these continental species ; 

 while this character and the smallness of the eyes, set very 

 wide apart, distinguish it at once from all other British 

 species of the genus. The more ovate, or more elongate, 

 form of the abdomen seems to me to depend upon the state of 

 the ovaries, and not to be too absolutely relied on for pur- 

 poses of identification. 



Taken at Hoddesdon, Hertfordshire, in April and May by 

 Mr. Campbel], and at Bloxworth, Dorset, by Rev. O. P. 

 Cambridge, and kindly forwarded for my inspection.

 caput bluffly rounded ; not very convex ; clypeus as high as 

 the ocular area, rather closely set with short erect hairs. 



Eyes. — Posterior row straight ; centrals one diameter 

 apart, one and a half from laterals ; central anteriors one 

 half diameter apart, one diameter from laterals, scarcely 

 smaller than laterals. 



Falces three times the length of the clypeus, convex at 

 base, slightly attenuate towards the apex, bearing two conical 

 teeth on inner angle and a third less conspicuous. 



Sternum dark, convex, shiny. 



Legs orange-red, dull. Femora i. with two spines, one in 

 front at apex, another on inner side a little above middle ; 

 ii. with one about the centre of the joint. Tibia' similar to 

 those of errans. 



Metatarsi with no spines at all. 



Abdomen varying from deep black to olive-green, clothed 

 with short curving hairs. 



Palpus of male orange-red, dull ; cubital joint short,
