EEIOCOCCUS GREENI. 201 



Habitat. On grass at Budleigli Salterton, Devon. 

 A single specimen was discovered by Mr. E. E. Green 

 in September, 1896. All attempts to rediscover this 

 species both by Mr. Green and myself have so far 

 failed. 



The species is easily distinguished from E. insignis 

 by the spinose character of the dermis, and the larger 

 and stronger legs and antennae.

Adult female "reddish-purple; oval, rounded in 

 front, narrowest and tapering posteriorly " (Green,

 legs, of seven joints, of which the third is generally 

 slightly the longest; formula 3, 4, 2, 1 (5, 6, 7), or 4 

 (3, 2) (1, 5, 6, 7); all the joints, with the exception of 

 the third, with fine short hairs. Rostrum doubtfully 

 trimerous. Anal orifice (fig. 12) with eight compara- 

 tively short hairs, arranged in pairs. Anal lobes 

 (fig. 12) normal, with one long terminal hair, one 

 short hair, and several spines. Dermis above thickly 

 set with large tubular spines, some of which are 

 pointed, others slightly truncate (fig. 13); ventral 

 surface with a few slender hairs and simple spinnerets.
