2. NOMADA. 129 



Male. — This sex closely resembles the female ; but the clypeus is 

 usually more yellow, and the scapo yellow in front, the clypeus 

 eovered with silvery pubescence ; the abdomen has its bands fre- 

 quently more interrupted. B.M. 



Var. /3. Abdomen having all the bands, except the apical one, inter- 

 rupted. This is probably the Nomada interrupta of Panzer. 



This species is at times very plentiful in certain localities, but it 

 is a local insect ; it usually appears in July, and is found in August 

 and September. I once found it entering the burrows of Andrena 

 fulvicrus, in August, at Sidmouth ; but I suspect it is usually para- 

 sitic upon species of Halicti. Kirby describes an insect which he 

 took in spring on the flowers of the gooseberry ; unfortunately only 

 a portion of his type remains. N. jacobcece he could not have found 

 at the time he mentions ; I believe his insect to be a male of iV. 

 snccineta ; it is certainly a larger bee than N. jacobcew. Kirby 's A. 

 jlavopicta is undoubtedly the female of Panzer's insect. This bee 

 is frequently found on the ragwort ; but it also frequents the Scabiosa 

 arvensis, on which flower I took it at Lundy Island.

iV. atra, antennis ferrugineis, scutello punctis duobus flavis, abdo- 

 minis basi ferrugineo maculata fasciisque flavis variegata, labio

Female. Length 4-6 lines. — Black ; a line along the lower portion 

 of the inner orbits of the eyes, the anterior margin of the clypeus, 

 the labrum, mandibles, and antennas ferruginous ; the scape has 

 sometimes a yellow stain beneath, and the flagellum is slightly fus- 

 cous towards the apex. Thorax — the collar, tubercles, tegulae, and 

 two spots on the scutellum yellow ; the legs ferruginous, the knees 

 stained with yellow ; the femora at their base beneath and tho 

 coxae and trochanters more or less black ; the posterior femora black 

 within ; the breast has a ferruginous spot on each side ; the wings
