 p. 97. 1. 



Female. Length 10 lines. The pubescence black, the man- 

 dibles bearded with black pubescence ; the wings deep brown, 

 with a violet iridescence in certain lights ; the disk of the ab- 

 domen subpubescent, shining ; the fourth and two apical seg- 

 ments clothed with rufo-fulvous pubescence ; beneath, the basal 

 margins of the segments glossy, smooth and shining, the fifth 

 segment fringed with fulvous hairs. B.M. 



Var. ft. The collar and scutellum obscurely yellow. 



Male. Length 6-7 lines. The pubescence black ; the second 

 segment of the abdomen with a lateral tuft of cinereous 

 pubescence, the four apical segments clothed with rufo-fulvous 

 pubescence ; the tarsi and posterior tibiae fringed with fulvous 

 hairs ; the wings fusco-hyaline, the nervures fusco- ferruginous. 



B.M. 



Var. ft. The thorax anteriorly has a mixture of cinereous hairs ; 

 the first and second segments of the abdomen have a lateral 

 tuft of cinereous pubescence. (A. Albinella, Kirby.) 



Var. y. The thorax anteriorly and posteriorly cinereous, the ab- 

 domen cinereous at the base. (A. frutetorum, Kirby.) 



Var. 8. The thorax anteriorly and posteriorly and the basal seg- 

 ment of the abdomen covered with cinereous pubescence ; the 

 second and following segments have fulvous pubescence. 



The variety of the female has not occurred in this country, 

 but it is met with on the continent ; it is probably the Apis are- 

 naria of Panzer. Of the male, var. ft. is the A. Albinella of 

 Kirby, var. y. the A. frutetorum of Panzer, and var. 8. probably 

 the A. pomorum of that author ; the latter variety is rare. The 

 species is occasionally met with in the London district, but it is 

 not abundant. The female once occurred in great numbers 

 at Coomb Wood, Surrey : the males are frequently met with, 

 and below Southend they have been observed in profusion 

 in the month of August : this species is probably the parasite of 

 B. lapidarius. 



2. Apathus campestris. 



A. hirsutus, ater; thorace antice, scutello anoque flavis; abdo- 

 minis apice acuminato inflexo. 



Apis campestris, Panz. Faun. Germ. 74. 11 . 

 Kirby, Mon. Ap. Angl. ii. 335. 88. t. 18. f. 2.
