40 BEES OF GREAT BRITAIN. 



and finely punctured; the flagellum fulvo-piceous towards 

 the apex beneath; the clypeus scarcely produced. Thorax 

 subopake ; the tegulse rufo-testaceous ; the wings hyaline, the 

 nervures pale testaceous ; the base of the metathorax subru- 

 gose, not enclosed ; the legs are dark rufo-testaceous and have 

 a pale fulvous pubescence, their apical joints ferruginous. Ab- 

 domen elongate-ovate, delicately punctured, the base very 

 smooth and shining, the margins of the segments rufo-testa- 

 ceous ; thinly clothed with short' pale pubescence, most dense 

 at the sides and towards the apex, the margins of the interme- 

 diate segments slightly depressed ; beneath, fringed with a long 

 pale pubescence. B.M. 



This species was first captured by Mr. C. Bowring, who pre- 

 sented specimens to the Museum ; since that time it has occurred 

 in plenty at the land- slip at Bonchurch, Isle of Wight, an excellent 

 locality for Hymenoptera, and one of the most beautiful spots in 

 the island. It is very distinct from all the other species, but most 

 nearly approaches the female of H. albipes, from which the neu- 

 ration of the wing at once separates it; the male is not known.

Female. Length 3f lines. Black, the head and thorax closely 

 punctured, a little scattered fulvous pubescence on the face and 

 disk of the thorax, on the sides of the latter it is more dense ; 

 the tegulse pale testaceous ; the wings hyaline, having a slight 

 fulvous tinge, the nervures pale testaceous ; the legs rufo-tes- 

 taceous, their pubescence pale fulvous, that on the tarsi beneath 

 pale fulvous, the tarsi ferruginous; the metathorax rugose. 

 Abdomen ovate, widest towards the apex, very glossy, smooth 

 and impunctate, the apical segments having a short pale pu- 

 bescence ; beneath, the margins of the segments have a fringe 

 of pale pubescence. 



This has hitherto been a rare species in cabinets, the type 

 being the only known specimen until a second was taken by Mr. 

 Dawson at Ventnor, Isle of Wight ; I have myself searched the 

 same locality, but captured H. longulus : I have some suspicion 

 that the latter may be a variety, but I have not felt justified in 

 uniting them ; the typical specimen in the Kirbyan collection is
