subhyaline, iridescent, and faintly obscured towards their apical 

 margins, the nervures rufo-testaceous ; the intermediate and pos- 

 terior tarsi, the apical joiuts of the anterior pair, and the posterior 

 tibiae pale rufous, the latter having usually a fuscous stain beneath ; 

 the floccus white ; the scopa of a golden yellow, having in certain 

 lights a glittering silvery brightness. Abdomen ovate, convex, and 

 shining, very delicately and finely punctured, the punctures faintly 

 impressed ; the three intermediate segments have on their apical 

 margins a narrow fringe of pale yellow pubescence ; the two apical 

 segments have a scattered short rufous pilosity ; the apical fimbria 

 is pale fulvous. B.M. 



Male. — The face clothed with griseous pubescence ; the clypeus 

 strongly punctured : the antennas nearly as long as the thorax, 

 their extreme apex testaceous, the joints subarcuate. Thorax the 

 pubescence griseous, that on the disk has a slight fulvous tinge ; the 

 legs covered with pale glittering pubescence, that on the tarsi 

 beneath golden yellow ; the apical joints of the anterior and inter- 

 mediate tarsi, the posterior pair, and the extreme apex of the tibiae 

 rufo-testaceous ; the wings as in the female. Abdomen ovate- 

 lanceolate, punctured and fringed as in the female. B.M. 



This species appears about the middle of April, and is found during 

 May and June ; it has not occurred, to my knowledge, in the imme- 

 diate vicinity of London ; it is found at litigate, Weybridge, Farn- 

 ham, and at Blackwater, and plentiful near Norwich ; but it must be 

 regarded as a local insect. Mr. Dale used to take it very plentifully 

 at Glanvilles Wootton, and noticed the remarkable circumstance 

 that a very large majority of the specimens were attacked by 

 Stylops.
