might probably belong to it, but the specimen is not in the Kirbyan 

 cabinet : it is described as having the head clothed with black hair ; 

 the antennae short. Thorax above dark rufous ; the nervures of the 

 wings yellow. Abdomen lanceolate; the margins of the segments 

 have a dense fringe. 





Sp. 41. Andrena articulata, Smith. 



Male. — (Length 5^ lines). Black ; the face clothed with fuscous 

 pubescence, a little black along the margins of the eyes ; the antennae 

 rather short, stout ; the joints subarcuate, nigro-piceous, exceptin 

 the two basal joints, which are jet-black. Thorax thinly clothe 

 above with pale fulvous, very pale at the sides and on the metathorax ; 

 the tegulae dark piceous ; the wings subfuscous, and slightly clouded 

 at their apical margins, the nervures testaceous ; the legs rufo-pi- 

 ceous, their pubescence fulvous; the apical joints of the tarsi ferrugi- 

 nous. Abdomen oblong-ovate, punctate, the margin of the basal seg- 

 ment sometimes rufo-piceous ; all the segments have a thin pale ful- 

 vous fascia ; beneath, the second segment is either rufo-piceous, or 

 has two rufous maculae, sometimes the rufous colouring is obsolete. 



This is a very distinct species, and I suspect is a very local insect. 

 I do not know any female to which I could imagine it might be 

 united. Mr. Desvignes and myself have each a single specimen. 



Sp. 42. Andrena rufitarsis. 

 Melitta rufitarsis, Kirby. 



Female. — (Length 5 lines). Black ; the face clothed with grayish- 

 white pubescence ; along the inner margin of the eyes, as high as the 

 vertex, is a line of short pale down ; the antennae beneath rufo- 

 fulvous, the basal joints black. Thorax clothed with dense pale yel- 

 low pubescence ; the tegulae rufo-piceous ; the w T ings subhyaline, 

 very slightly clouded at their margins, their nervures piceous ; the 

 legs rufo-piceous, and have a pale ochraceous pubescence ; the floc- 

 cus is of the same colour; the scopa inclining to fulvous ; all the tarsi 

 rufous. Abdomen oblong-ovate ; the margins of the segments are 

 narrowly piceous, and have a thick fringe of pale yellow pubescence ; 

 the anal fimbria fulvous. 



This is a rare species : I have never met with it, nor have I seen 

 it in any but the Kirbyan cabinet ; it closely resembles the next spe- 

 cies A. fuscipes, but its legs are of a paler colour as well as their pu-
