232 Mr. E. Saunders' Synopsis of 



depression near the inner margin of the eye, filled with 

 very short shining adpressed hairs. Thorax much like 

 that of the (? , but less hairy, and the metathorax rather 

 more rugose. Abdomen shining, sometimes black as in 

 the (? , sometimes with the 1st and 2nd segments and 

 apical margin of the 3rd, ferruginous-red ; the base of 

 the 1st and 2nd generally black ; between these forms 

 great variation occurs. Surface very finely punctured ; 

 2nd, 3rd, and 4th segments with a lateral streak of 

 whitish hairs ; 5th and 6th clothed densely with golden 

 hairs ; segments beneath fringed with long hairs. Legs 

 black ; tarsi more or less testaceous : tibise clothed with 

 long golden grey plumose hairs. Length 14 — 16 mm. 



Hah. Ventnor ; Erith, Darenth, Birch Wood, Kings-

 Devon ; and S. Wales. It is found chiefly on the common 

 Scabious, according to F. Smith, and the high coloration of 

 the ? he thinks depends upon the dryness or heat of the 

 season, as in hot dry summers he has found nearly all 

 the females coloured.
