Genus Halictus, Lair. 



Div. II. — The females with abdominal fascias on the basal 

 margins of the segments ; the body entirely black. (Sp. 

 7 to 22). Sec. 1. 



7. Halictus xanthopus. 

 Melitta xanthopus, Kirby, Mon. Ap. Angl. ii. 78, male, 



female. 

 Lasioglossum tricingulum, Curtis, Brit. Ent. x. p. 448. 

 Halictus xanthopus, Brulle, Exped. de Moree, iii. 349 ; 

 St. Farg. Hym. ii. 273 ; Smith, Brit. Bees, p. 24 ; 

 Nyland. Revis. Apum Boreal. 238 ; Imhoff, Ins. 

 Switz. No. 3, female. 

 This is the largest species of the genus found in this 

 country : it is very local, and appears to be usually found on 

 the coast, but it also occurs inland : Mr. Kirby took it at

 Hastings, Little Hampton, near Lewes, and at Southend. I 

 have not seen any specimens from the North of England. 



8. Halictus leucozonius.

female.

Bees, 25 ; Nyland. Revis. Apum Boreal. 

 Hylyeus leucozonius, Schenck, Bees Nassau, 366. 

 In this country no species is more abundant : the males 

 are frequently found as late as the end of October, in the 

 flowers of the mouse-ear. When in fine condition, the 

 pubescence of the female is griseous on the head and 

 thorax ; the latter is strongly and closely punctured on the 

 disk, the metathorax being truncate and rugose; the ab- 

 domen finely and closely punctured ; the fasciae at the base 

 of the segments, which are depressed, snow-white and even,
