merely the base of the third red, the second and third segments with 

 a lateral black dot, sometimes also a central dot ; in some instances 

 only the margins of the segments are rufo-piceous : beneath, one, two 

 or three segments red. 



Male. — (Length 4 lines). Brown-black, clothed with pale fulvous 

 pubescence ; the antennae fuscous ; the clypeus white, with two black 

 dots ; the wings subhyaline, their apex clouded. The abdomen ob- 

 long-ovate, the margins of the segments slightly piceous, tip of the 

 abdomen pale fulvous ; beneath, the segments have a marginal fringe 

 of pale fulvous hair. 



The female of this species is extremely variable in the colouring of 

 the abdomen, every shade of variety occurring between the extremes 

 described. The pale fulvous pubescence of recent specimens soon 

 fades, so that the general character is hoary. Mr. Kirby's Melitta af- 

 finis is undoubtedly a variety of A. Cetii. I possess a similar variety 

 taken in company with the highly coloured specimens. Mr. Kirby 

 used to take the female in Suffolk ; the male he did not know, and I 

 believe it is now first described. I have taken this bee in Hamp- 

 shire, and have received specimens from Mr. S. Stevens, taken by him 

 in Sussex, in August.

 mandibles ferruginous at their tips ; the face clothed with dark brown 

 hair. Thorax, the tegulae dark piceous ; the wings hyaline, their ner- 

 vines piceous ; the legs dark rufo-piceous ; the floccus and scopa be- 

 neath pale fulvous, the latter dark brown above ; the tarsi ferruginous. 

 Abdomen, two minute dots on the basal segment, its margin, and also 

 the margin of the second, ferruginous ; the apical fimbria black ; be- 

 neath, the second segment is sometimes wholly, sometimes only at the 

 base red. 



Var. 2. — The red spots on the basal segment obsolete. 



Male. — (Length 5 — 5 J lines). Black, with a light brown pubes- 

 cence ; head large, the pubescence on the face black ; the mandibles 

 long and curved, their tips ferruginous and acute, having a long fili-
