wild thyuie and on the ragwort. I have taken some hundreds of spe- 

 cimens, but never found a male with the abdomen rufous ; but the 

 females may be found greatly varying in size and colour, ranging from 

 jet black to pale rufous, with every shade of tint between. I feel 

 quite satisfied that the picta and rufo-picta of Kirby are only varieties 

 of Solidaginis. Panzer has figured the male. 



Sp. 9. NOMADA OCHROSTOMA. 



Apis ochrostoma, Kirby's Mon. 



Male, (3 to 4£ lines). Black : face clothed with silvery hair ; cly- 

 peus, labrum and mandibles yellow, the latter rufous at the tips ; the 

 scape of the antennae rufous on the inner sides, the remaining joints 

 rufous, with four or five basal joints stained behind : thorax, the 

 collar, tubercles, a spot below them, the tegulae, and a transverse 

 patch on the scutellum, rufous ; legs rufous ; the coxae black, except 

 the extreme apex ; the trochanters black, with their apex rufous ; an- 

 terior and intermediate femora black at their base beneath ; the pos- 

 terior black beneath : abdomen rufous, first segment black at the 

 base, the second with an ovate acute macula, the third, fourth and 

 fifth generally with interrupted narrow fasciae, the fifth slightly inter- 

 rupted, the sixth entire ; beneath rufous, the sixth segment with a 

 yellow spot, sometimes variegated indistinctly with yellow. 



Var. 1, (4 lines). The clypeus rufous; the maxillae variegated with 

 yellow ; the scape quite black ; five abdominal fasciae interrupted, the 

 sixth entire ; other varieties occur in the latter particular. 



I consider this variety to be the Apis Hillana of Kirby, having spe- 

 cimens exactly agreeing with the description ; unfortunately there is 

 no specimen in the Kirbyan cabinet : the specimen from which the 

 description was drawn up was in the cabinet of Mr. Hill. I consider 

 Nomada vidua to be the female of N. ochrostoma. I take them in 

 company at Colney Hatch wood : it is also found on Hampstead 

 Heath, but is scarce. 



Sp. 10. NOMADA RUFIC0RNIS. 



Apis rujicornis, Linn. Kirby' s Mon. 

 Female, (3j to 5j lines). Black : labrum and maxillae rufous, pi- 

 ceous at their tips, a spot on the face, below the base of the antennae, 

 the clypeus, a line encircling the eyes, and another encircling the 

 stemmata, rufous ; antennae rufous : thorax, the collar, tubercles, a 

 large patch on the breast, the tegulae, four lines between them, the 

 scutellum, and two spots below on the metathorax, rufous ; the api- 

 cal margins of the wings dark, a pale lunule towards their tips ; the
