202 Mr. E, Saunders' Sijnopsis of 



the others which have apically banded segments, by the 

 clear yellow tibise ; the J by its simple mandibles, and 

 the bands, not spots, at the sides of the segments. 



Hah. Common in many sandy places. 



2. Halictus quadricinctus, Fab. 



Fab., Syst. Piez., p. 319 ; Smith, Cat. Brit. Hym., 

 2nd ed., p. 80. 



Black ; head and thorax rather densely clothed with 

 hairs in <? , sparingly clothed with dull brown hairs in 

 the ? ; segments of the abdomen with white apical 

 bands. Wings hyaline. 



(? . Head elongate ; clypeus much produced, with 

 a whitish yellow transverse spot at the apex ; mandibles, 

 looked at sideways, dilated at the base. Antennae long, 

 reaching to beyond the thorax ; surface of the head 

 closely punctured. Thorax punctured as the head, rather 

 thickly clothed with greyish brown hairs ; metathorax 

 finely rugose. Abdomen elongate, subclavate, punctured, 

 and clothed with very short erect hairs ; the first four 

 segments each with an apical band of white pubescence, 

 that of the 1st segment largely interrupted in the middle ; 

 beneath flat, almost glabrous ; 4th and 5th segments 

 emarginate, and fringed at the apex with short golden 

 hairs ; (for genitalia see pi. viii., tig. 7). Legs covered 

 with short hairs. Anterior and intermediate femora in 

 front, and all the tibiae and tarsi, testaceous ; posterior 

 tibiae with a black spot on each side. 



? . Something like that of ruhicundus, but with all 

 the legs black, the hairs only being golden, and the tarsi 

 more or less testaceous. Head and thorax punctured ; 

 metathorax finely rugose. Abdomen scarcely shining, 

 closely and evenly punctured all over ; first four segments 

 each with a white apical band of pubescence ; those of 

 the 1st and 2nd segments interrupted ; 5th segment 

 with pale golden hairs on each side of the central rima ; 

 beneath densely clothed with long golden hairs. Length 

 9 mm. 



Hah. Very rare. Sir Sidney Saunders has taken 

 the ? near Eastbourne, and both sexes near Brighton 

 in August ; and I am indebted to him for the specimens 

 from which I have described. Mr. Dale took the ? in 

 the Isle of Portland, and Mr. Kirby quotes the London
