In colour and general appearance ifc is like several of our species, but I think it 

 more closely resembles pictus than any other ; from this, however, and from all its 

 apparent allies it may be separated at once by the following sectional characters : — 

 Bnsal segment of abdomen without any basal transverse carina, antennae of the $ 

 terminating in a hook as in the Ancistrocerus section ; the ? may be known from 

 any of the Hoplopu^ section by the less cupuliform basal segment of the abdomen 

 and the absence of any central impression near the apical mai'gin. 



Odynerus {Si/mmorplius) hifasciatus, Linn. (Ent. Mo. Mag., xxxviii, 



p. lOG). 

 We are indebted to Mr. W. H. Tuck of Bury St. Edmunds for 

 this addition, of which he found numerous specimens iti his own 

 neighbourhood ; it is very closely allied to sinuatus, but may be 

 known from it by the following characters : — 



The post petiole of the first abdominal segment in hifasciatus, i.e., the portion 

 beyond the basal transverse ridge, is more quadrate and less cone shaped than in 

 sinuatus, the sides diverging from the basal ridge much less rapidly, the general 

 effect being that the post petiole of hifasciatus looks and really is distinctly broader 

 than long, whereas that of sinuatus looks longer than wide, although actually the 

 apical margin is longer than the length of the post petiole, the longitudinal fovea 

 of the disc in hifasciatus is less defined than in sinuatus, the pronotum is entirely 

 black, the legs are less variegated with yellow, and the abdominal bands are slightly 

 narrower. 



Anthophila.. 

 Colletes montanus, Mor. (Ent. Mo. Mag., xxxv, p. 262). 



This species was first sent to me by Mr. A. A. Dalglish, who took 

 both sexes on Irvine Moor, near Glasgow, in July, 18S9. It has since 

 been taken by Col. Terbury at Waterville, in Ireland, in July and 

 August, 1901. 



It resembles C. daviesanus in the shining, finely and comparatively remotely, 

 punctured basal segment of the abdomen, and is very distinct from any of our other 

 species. The ^ may be known from daviesanus by its brighter coloration when 

 fresh, the absence of the hairy tooth at the side of the 6th ventral segment, and 

 the form of the Vth, which is produced into two long parallel-sided processes 

 slightly spatuliform at their apices, and the absence of the long knife like blades of 

 the sagittce so characteristic of the armature of daviesanus. In the ? the face is 

 not so wide as in daviesanus, and the cheeks between the eyes and mandibles dis- 

 tinctly longer, the hairs of the face white ; abdomen coal-black, basal segment rather 

 strongly, but not very closely, punctured, the bands of the segments white. 



V Frosopis spilota, Forst. = masoni, E. Saund. 



The very perplexing group with dilated scapes in the ^ has been 

 carefully studied by Mr. J. D. Alfken of Bremen, who has had the
