This pretty little bee seems to connect Coelioxys (pi. 349.) 

 and Nomada (pi. 419.) ; from the former it is readily distin- 

 tin^uished by the additional submarginal cell, and from the 

 latter by its conical and pubescent abdomen. There are also 

 other more important distinctive characters, but less visible, 

 such as the great length of the basal joint of the labial palpi, 

 with the 2nd joint acuminated, the minute maxillary palpus 

 of one joint, as in Anthidium (pi. 6J.), the obtuse lobe of 

 the maxillae, and the singular labruni with a small tooth in 

 front and two above it, forming a triangle, which seem to have 

 escaped the observation of Mr. Kirby and M. Latreille. 



It is a remarkable fact noticed by Mr. Kirby, that the male 

 of this bee was unknown to him. I have taken a very consi- 

 derable number of specimens, and am much gratified at having 

 discovered one male amongst them, since it enables me to state 

 that Panzer's figure is of that sex, and not a variety of the 

 female ; for my male has an entirely black labrum and scu- 

 tellum, with the lobes also black and less prominent than in 

 the other sex : the 5th and 6th segments of the abdomen have 

 a long transverse band of ochreous hairs entirely covering the 

 back, and the little apical lobe is also black. The male is as 

 large as the female, but the abdomen is more ovate, with 6 

 joints : the antenna3 are rather shorter if anything, although 

 13-jointed, and the basal joint of the hinder tarsi is clothed, I 

 think, with rather longer hairs. 



The females seem to vary considerably in size, and the 

 authentic specimen in the Linnsean cabinet mentioned by Mr. 

 Kirby as having a black scutellum is probably the male. 



In Hampshire this bee is very abundant at the middle and 

 end of August, on sandy and gravelly districts covered with 

 the Calluiia vulgaris and other heaths, as Parley Common 

 and Ramsdovvn near Heron Court. Mr. Samouelle once met 

 with it in a sand-pit near Bexley, Kent, in July, where Mr. 

 Johnson has lately taken it ; Mr. Dale has captured it the 

 beginning of August at Blackgang Chine ; and Mr. Kirby 

 found it, "but by no means common, in the autumn of two 

 succeeding years, 1797 and 1798, flying about sunny banks;" 

 and he adds, " since then I have not met with it."
