pale yellowish grey spots formed by side rows of distinct small oblong 

 well-defined isolated side flecks and by a middle row of less distinct 

 short triangles on the hind margins of the second to sixth (or some- 

 times only to fourth) segments ; the side flecks on the second and third 

 segments sloping from near the base outwards, and isolated as they by 

 no means extend to the hind margins, and outside the flecks the 

 second segment is indistinctly brown or pale reddish brown to a small 

 or very small extent at the basal corners ; on the following three segments 

 the sideflecks less oblique and conspicuous, and gradually becoming smaller 

 towards the posterior segment ; the triangles composed the middle row 

 often extending in a thin point up to the foremargin ; all the surface 

 covered with a grey tomentum especially on the flecks and hindmargins 

 very dense and sometimes with yellowish one, and clothed with nume- 

 ous somewhat depressed short black rather bristly pubescence which 

 becomes more erect and longer on the seventh segment, except on the 

 greyish flecks and hindmargins white pubescent, and the middle incised 

 portion of the basal segment and the very small area just below the 

 lateral margins of the scutellum bearing a few rather frizzled white 

 pubescence ; the side hairs all blackish and longer but the two basal 

 segments whitish and much numerous. Ventre ashy grey with a 

 shimmering light grey tinge caused by the dense light grey tomentum 

 and the somewhat depressed white pubescence which becomes longer 

 and sloping about the middle through the length ; hindmargins of the 

 segments more or less conspicuously and equally pale yellowish ; seventh 

 segment with usi>il long erect though curved black bristly hairs which 

 slightly extend up to the hind border of the just preceding segment. 



Length: 13-14 mm.
