intermediate coxa3 of the S 3'ollow, produced into a long 

 yellow spine, femora yellow, black at the base, tibia) and 

 tarsi yellow. 



L. 12-13 mm. 



Very rare; has occurred near Chobham, Surrey, in two 

 localities, and Mr. Billups has taken it near Virginia Water 

 Station, about four miles from Chobham. The yellow 

 spines on the coxaj of the S and the broad yellow baud of 

 the clypeus of the ? at once distinguish this species from 

 its allies ; it makes curved tubular entrances to its burrows ; 

 these I have only once met with on a level sandy spot on 

 Chobham Common. 



0, basalis, Smith. — Black, more strongly punctured 

 than any of the preceding; head with a spot between the 

 antennae, a line in the lower part of the sinus of each eye, 

 and a spot behind each eye yellow, antennaj beneath 

 testaceous in both sexes, ^ with the rather deeply emar- 

 ginate clypeus, and scape in front pale yellow, and only with 

 the penultimate and apical joints of the antennas recurved ; 

 thorax very largely and closely punctured, pronotum with 

 an anterior band, the tegulre, a double transverse spot at 

 the apex of the scutellum, and in the ? a transverse line 

 on the postscutellum, pale yellow, wings smoky in front, 

 uervures brown, reddish testaceous towards the base; 

 abdomen largely punctured, especially on the basal 

 segment, which is red, except a black central line and the 

 apical pale yellow band, the following four segments have 

 each a pale apical baud, that of the second segment 

 slightly dilated at the sides ; legs simple in both sexes, 

 reddish testaceous. 



L. 12-13 mm. 



Very rare. Mr. Rothney took a ? on Stowborough 

 Heath, Dorsetshire, on the 24th of July, 1878, and 

 Mr. Dale has taken the S in the Isle of Portland. I know 

 of no other records of its capture, and of none of its habits,
