 closely punctured ; 1st segment impressed at the apex ; 

 2nd and 3rd much impressed at the base, apical mar- 

 gins more or less testaceous and impunctate ; each 

 segment has a slight apical band of pale hairs ; beneath

Smith, Zool. vii., App. 58 ; Cat. Brit. Hym., 2nd ed., 

 p. 95. 



Easily distinguished from the preceding by the short 

 antennae of the c? , which reach only to about the middle 

 of the metathorax, and the bronzy femora, and by the 

 dense pubescence of the ? , which is of a golden, almost 

 fulvous, tinge ; the tegulae and nervures of the base of 

 the wings are pale yellow, and the anterior tibiae in front, 

 and the base of the others, and all the tarsi, are more 

 or less flavous. Length 6 — 7 mm. 



Hah. A verj^ rare species in England, and very distinct ; 

 the only recorded localities are Cove Common, Hants, and 

 Devonshire. It is not rare in the South of Europe.
