brood, when freshly emerged, has the face clothed with brownish 

 hairs, and is then easily distinguished. It is, perhaps, not always 

 possible to distinguish between the ? $ of the two broods, but 

 generally the niesonotal puncturation is more distinct in the summer 

 form, and in very fresh examples that I have compared, the pubescence 

 of the middle of the face is always longer and more plentiful in the 

 spring brood. The $ <j> of the second brood are often extremely 

 numerous on the flowers of Rubus, and may occur on these quite un- 

 mixed with the following, even in localities, where both occur. On 

 Umhelliferse both are often found together. 



A. minutuloides, sp. nov. All the $ <$ that I have seen have the 

 face clothed with very pale or whitish hairs. In both sexes the thorax 

 is smoother than in minutula. It appears to be rather a heath- 

 frequenting or upland species than the other, which is found in all 

 sorts of localities. It appears to me quite possible that it is the second 

 brood of the following. The variation in thoracic and abdominal 

 puncturation, as well as in the sculpture of the propodeal area makes 

 it most difficult to describe. I have taken the sexes in cop. 



A. parvuloides, sp. nov. I have not found the sexes in cop., and 

 have taken the $ as the type of this form. It appears normally later 

 than parvula, which it greatly resembles. It is no doubt common, but 

 there are few specimens in the collections, I have examined. It appears 

 to frequent the same kind of localities as the preceding. Females of 

 these two are sometimes hardly separable. 



In England, A. spreta, saundersella, and subopaca are very subject 

 to the attacks of Stylops. A. parvula is, I think, very rarely affected. 

 The others I have not found stylopized 



I have to thank all those who have allowed me to examine their 

 specimens, and especially the Eev. F. D. Morice, who lent me both 

 his Continental and British series. From Messrs. A. H. Hamm, 

 J. J. F. X. King, E. B. Nevinson, and Lieut.-Col. Nurse I have also 

 had specimens for examination, and have further examined the ex- 

 tensive Cambridge Museum Collection, and those in Mr. Arnold's. I 

 am still further indebted to Herr J. D. Alfken, who is working at the 

 German species, for allowing me to send him a series of a number of 

 our British forms and for valuable information concerning these. My 

 friend Mr. A. Koebele sent me many fresh specimens from Baden. 

 Though Andrena proximo, Kirby, is a true member of this group of 

 bees, I have not thought it necessary to include it in my tables, its
