594 Insects. 



Male, (6 lines). Head, face as in the female, but the mandibles, 

 &c., not stained ; the scape of the antennae sometimes yellow in front, 

 sometimes totally black ; six or seven of the basal segments black 

 behind, the remainder rufous : the tegulae pale yellow : scutellum with 

 two yellow spots, sometimes obsolete : abdomen with six yellow fas- 

 ciae, the first, second and third widely interrupted, so as to form six 

 oblong maculae ; beneath, the third, fourth and fifth segments have a 

 yellow fascia, the margins piceous ; the sixth is yellow, with a biden- 

 tate black stain at the basal margi^. This sex is the Nomada sex- 

 fasciata, Jurine, and the Apis connexa, Kirby. 



It is a rare species. I have, however, taken it abundantly para- 

 sitic upon Eucera longicornis, at Highgate ; excepting there I never 

 captured but a single specimen, — a female, at Darent wood.
