The uniformity that prevails in the structure of these bees, 

 especially in the similarity of the palpi and the antennae of the 

 sexes, renders it easy to distinguish them from the other Ajridce, 

 and nothin'>- can be more natural, I think, than the situation 

 assio-ned to them by Mr. Kirby, for in habit they so much 

 resemble Dasi/poda, that Fabricius (who must have judged in 

 this instance from analogy and not from dissection, as the 

 mouth assumes the more developed form of the Ajndce) had 

 included them in his last work in that genus ; and on the other 

 side they approach very near to Nomada, in the form of the 

 palpi and other parts of the organs of manducation. 



We have but 2 species of this genus ; for as Apis ursina, 

 and A. BanksiaJia of Kirby are constantly found together, the 

 former beinjj all females and the latter all males, it cannot be 

 doubted that they are one species. 



1. Panurgus ursinus, Mr. Kirby took upon a heath in Suffolk, 



in September, and in the middle of June I captured 

 several of both sexes upon a sunny bank near 

 Shooter's Hill. The female having been figured in 

 the Moil. Ap. Angl. tab. 16. f. 1., 1 have preferred 

 giving the male, being in doubt about Panzer's figure 

 of Trachusa atra^fasc. 96. pi. 19. all the tibiae being 

 destitute of the fulvous pubescence. 



2. P. lobata Panz. Both sexes of this rare insect are well 



figured in his Fawi. Ins. Germ. fasc. 96. 18. male, 

 and 72. 16. female. Having received specimens 

 from Germany, and Mr. Stephens having allowed 

 me to compare his specimen, which was the one in 

 the late Mr. Marsham's collection, referred to by 

 Mr. Kirby, there can be no doubt of their being the 

 same species, although the figure in the Mon. Ap. 

 Angl. tab. 16. f. 2. does not show the spines on the 

 posterior thighs, as exhibited in our plate (fig. 8f ), 

 which are quite concealed, except when the legs are 

 spread out ; a proof of the utility of setting insects 

 well when firat taken, or of relaxing them after- 

 wards, as recommended by Mr. Samouelle in his 

 Useful Compendium, p. 321. 

 The female of P. lobata I have never seen ; the males have 

 been taken in September upon Martlesham Heath, near 

 Woodbridge, Suffolk, by Mr. Kirby, whose specific name 

 would most willingly have been adopted, had not Panzer pub- 

 lished his previously. Latreille observes, that our bee is fond 

 of semidosculous flowers ; we have consequently figured Ci- 

 neraria integrifolia (Mountain Fleawort), communicated by 

 Professor Henslow from the Gogmagog Hills.
