and intermediate tibiae, and all the tarsi spined in the 

 ? . Length 18—22 mill. 

 Common on sandy banks, &c.

Differs from the preceding in having the 3rd sub- 

 marginal cell petiolated (/. c, almost always), and the 

 metathorax finely and regularly transversely rugose, the 

 rugosities in distinct diagonal lines meeting along the 

 centre ; the colour of the abdomen in the male generally 

 darker than that of .sdhulosa, and more densely covered 

 with silvery hairs. Length 15 — 20 mill. 



Hdh. — Often with the preceding, but generally less 

 common ; abundant however near Chobham, Wey- 

 bridge, &c.

3' , head and thorax black ; largely and rugosely 

 punctured, densely covered with hah-s, which are black 

 on the head and prothorax, and more or less grey on 

 the rest of the body; metathoracic area rugose, not 

 diagonally striate ; petiole of the abdomen black, with 

 long hairs beneath, rather longer than the 2nd segment ; 

 2nd, 3rd, and base of the 4th segment red, the rest 

 black ; abdomen covered with a very short grey sericeous 

 pubescence, giving it a more or less silvery appearance ; 

 2nd segment much widened posteriorly ; legs black ; 

 coxse and femora with long hairs. 



? differs in being larger and more robust, and in 

 having the head and thorax, &c., densely covered with 

 black hairs. The body also is larger and more shining, 

 being glabrous, without the sericeous pubescence of 

 the (? . All the tibiae spinose ; posterior tibiae with a 

 dense silky pubescence on their inner side. Length 

 15—20 mill. 



Hah. — Common in sandy places. 



Can only be confounded with the following ; it differs 

 from the preceding at once by the shape of the 2nd 

 abdominal segment, which in this species is much 

 widened behind, and by the great hairiness of the head 

 and thorax.
