COLLETlD.e. IT9 



dull colour and small size it resembles marginala. Head and 

 thorax somewhat remotely punctured ; abdomen shining, 

 basal segment clothed with long pale hairs, finely, and in 

 the ? remotely, punctured, the following segments in both 

 sexes still more finely punctured, each with an apical band 

 of pale pubescence, second and following segments in the ^ 

 clothed with long black erect hairs, in the ? with shorter 

 dusky hairs, sixth ventral segment in the (^ with a strong 

 blunt hairy tooth on each side, armature with the sagittfe 

 very long, and resembling two concave knife blades, quite 

 unlike those of the other species. 



L. 8-9 mm. 



Probably the commonest species of the genus ; it occurs, 

 like the others, in July and August, and is very partial to 

 Chamomile flowers, Senecio, &c.; often forms large colonies 

 in hard sandstone. 



C CUnieularia, Linn. — Almost twice as large as any 

 of the preceding, black- brown, head and thorax densely 

 clothed with dull brown hairs, those on the face of the (J 

 paler, head very closely and rugosely punctured, thorax 

 largely and remotely, antennte in the ($ reaching to about 

 the scutellum, those of the ? shorter, abdomen clothed 

 with erect, brownish hairs, each segment with a narrow, 

 paler, apical fringe, subelliptic in the c?, broadly ovate, its 

 apex pointed in the ? , more or less shining, its punctura- 

 tion fine, more rugose and coarser in the c? ; armature of 

 the S with the sagittaj narrow, longer than the stipites ; 

 legs in the c? clothed with pale hairs, in the ? with brown 

 hairs externally, with pale on their inner sides. 



L. 14-15 mm. 



Quite unlike the other species of the genus ; could only 

 be mistaken for an Andrena or a Hive Bee. It occurs at 

 Wallasey; Southport ; Waterloo Coursing Ground, near 

 Liverpool; Crosby; Blackpool; Rock Ferry ; Chester. It 

 is a spring species, the females being taken at Sallow 

 blossoms; this year, 1893, the male occurred as early as
