Andrena Aprilina, Dale, MSS. 



Male. — (Length 4j lines). Black; the clypeus clothed with brown 

 pubescence, with fulvous at the base of the antennae, which are not 

 quite so long as the head and thorax ; the joints subarcuate; the apex 

 of the mandibles ferruginous. Thorax very closely and finely punc- 

 tured, clothed with fulvous pubescence, most sparing on the disk, and 

 palest on the sides of the metathorax ; the tegulae nigro-piceous ; the 

 wings sub-hyaline, slightly clouded at their apical margins ; the 

 nervures testaceous ; the pubescence on the legs fulvous, with which 

 the posterior tibiae are thickly clothed ; the tarsi ferruginous. Abdo- 

 men oblong-ovate, shining, the margins of the segments piceous, the 

 second and third sub-depressed ; the margins of the segments are 

 thinly fringed with fulvous pubescence ; the pubescence on the apical 

 segment is of a brown-black. 



This very distinct species was transmitted to me by Mr. Dale, with 

 the name adopted. It is, I expect, a very local species. The speci- 

 men described, and one in the British Museum, are all that I have yet 

 seen. The female is not known. 



Andrena eximia, Smith (Zool. 1930). 



Female. — (Length 5| lines). Black ; the pubescence on the face 

 and cheeks is fulvous ; the antennae nigro-piceous beneath, the apical 

 segment piceous ; the clypeus smooth in the centre, and coarsely 

 punctured laterally ; tips of the mandibles ferruginous. Thorax very 

 finely punctured, with larger punctures intermixed ; the disk naked ; 

 the sides, and metathorax laterally, clothed with fulvous pubescence ; 

 the wings sub-hyaline ; the nervures rufo-piceous ; the pubescence 

 on the legs above is fuscous, beneath pale fulvous; the apical joints 

 of the tarsi ferruginous ; the floccus and scopa beneath pale fulvous, 

 the latter fuscous above. Abdomen smooth and shining ; the apical 

 margin of the basal segment, and the second and third segments, en- 

 tirely red ; the apical fimbria fuscous, beneath very finely punctured. 



T captured a female of this species some years ago at Darent Wood, 

 and had considered it as an extreme variety of A. Rosae, which it 

 closely resembles ; but Mr. Weir captured a series of specimens of 

 both sexes on the 10th of April, 1846, at Pembury, Kent: they were 

 crawling on a sand-bank, benumbed with cold. My female was cap- 

 tured in the beginning of May, and Mr. Heales captured the males, as
