the long acute paraglossse, it advances towards the higher Apidce ; 

 this genus, therefore, offers another case which breaks the continuity 

 of such a scale as that proposed in the " Fertilisation of Elowers." 



Again, at p. 53, Dr. Miiller would appear to have placed Mac- 

 ropis on a higher level than Eucera, Anthophora, &c., on account 

 of its having contracted the "new habit " of "moistening the pollen 

 with honey before placing it in the collecting apparatus;" but Macropis 

 is a short-tongued bee, structurally closely allied to Andrena, &c., so 

 that in this case structure and usefulness of habit would not appear 

 to have progressed together. 



At p. 55, it is said of the Dasygastrw that " the whole or nearly 

 the whole ventral surface of the abdomen is covered with a brush of 

 stiff bristles, inclined backwards, which vary in length, closeness, and 

 colour in different species, but are always smooth, without trace of 

 feathery branching." I would only remark here than in many of the 

 species these hairs are beautifully spirally grooved (see Trans. Ent. 

 Soc. Lend., 1878, pi. xi, fig. 3) ; and in one genus, Ohelosfoma, they 

 have distinct long filamentary branches (see Trans. Ent. Soc. Lond., 

 1878, pi. vi, fig. 8). 



I do not make these remarks in any way to dispute Dr. Miiller' s 

 theory of the gradual development of the mouth parts in Hymenoptera, 

 I only think that there are signs that such development did not occur 

 along the exact lines which he suggested ; and having noticed these 

 little inaccuracies, which happen to be in matters to which I have 

 given special attention, I feel bound to point them out. Coming from 

 such an important authority as Dr. Hermann Miiller, one cannot but 

 feel that they would be likely to be accepted, and might be made the 

 foundation of many erratic conclusions.
