thinly clothed with very pale ochraceous pubescence ; a fringe of the 

 same on the sides of the metathorax ; the tegulae piceous ; the wings 

 iridescent, sub-fuscous at their margins ; the floccus white ; the scopa 

 of a pale golden yellow above, changing to silvery white beneath ; the 

 basal joint of the posterior tarsi of a golden yellow within ; the apical 

 joints of the tarsi ferruginous. Abdomen sub-ovate, convex, and very 

 shining; the margin of the second, third and fourth segments has a 

 lateral white marginal fascia ; the anal fimbria golden yellow, having 

 in some lights a silvery reflection. 



Male. — (Length Sj lines). Black ; a little whitish pubescence on 

 the face ; the antennae nearly as long as the head and thorax. Tho- 

 rax very thinly clothed with pale ochraceous pubescence, which is 

 also the colour of the pubescence on the legs ; the apical joints of the 

 tarsi ferruginous. Abdomen oblong-ovate, very smooth and shining ; 

 on the margin of the second, third and fourth segments, laterally a 

 little white pubescence, and at the extreme apex a little bright yellow. 



Mr. Kirby's M. digitalis T consider to be a variety of the female of 

 A. proxima. This species I never met with near London : I have 

 taken both sexes in Hampshire : I believe it also occurs at Bexley 

 Heath, and at Highgate, but not abundantly. I believe it is a very 

 local insect. The sexes are now first united : they bear a close re- 

 semblance to each other: in Mr. Kirby's Monograph the male is 

 described under the specific name of Collinsonana.

 the wings iridescent, hyaline, and slightly clouded at their margins ; 

 the tarsi ferruginous ; the floccus white ; the scopa above fuscous, 

 beneath silvery white. Abdomen very smooth and shining ; the mar-
