Sp. 16. Nomada lateralis, Panzer. 



Female, (5|- lines). Head black ; mandibles, labrum, clypeus, and 

 a line encircling the eyes, rufous ; antennas rufous, the scape stained 

 above : thorax, the collar, tubercles, a large patch on the breast, the 

 tegulae, four lines between them, the scutellum, two minute spots be- 

 low, and two oblique lines at the lateral margins of the metathorax, 

 rufous : legs rufous ; anterior and intermediate coxae black at their 

 extreme base, the posterior pair black at their base within ; the tro- 

 chanters and base of the femora black beneath : abdomen rufous, 

 black at the base, the second and third segments with lateral, large, 

 yellow maculae, acute within, the fourth with a subinterrupted abbre- 

 viated yellow fascia, and the fifth with a square yellow patch ; be- 

 neath rufous, sometimes with dark stains in the centre of two or three 

 segments. 



Male, (4 to 5^ lines). Head black ; mandibles, labrum, clypeus, 

 and inner orbits of the eyes, as high as the base of the antennae, yel- 

 low, the yellow patch on the clypeus being tridentate : antennae ru- 

 fous, the scape yellow in front, slightly stained behind, as well as four 

 or five of the basal segments : thorax, the tegulae and tubercles rufous, 

 a yellow spot below on the breast ; the coxae black ; all the femora 

 black beneath, except at their apex ; all the tibiae with a dark stain 

 behind : abdomen as in the female, but with three pairs of maculae, 

 the interrupted fascia, and the square patch ; beneath, a central, ab- 

 breviated yellow fascia on three or four segments, the margins piceous 

 in the centre : the face, cheeks, underside of the thorax, coxae and 

 femora, covered with silvery pubescence. 



I believe this beautiful species was introduced to the British Fauna 

 by Mr. Shuckard, who found it on Hamp stead Heath, where 1 have 

 also captured it. It frequents the burrows of Andrena albicrus ; is 

 confined to a small patch on the Heath, above the round pond to the 

 south ; and appears in June.
