Of the species described as having white orbital 

 markings, the present seems to be most closely allied to 

 effodiens, Fert., of which the author has kindly sent me a 

 specimen, but it differs from that species in the absence 

 of the dense beard on the underside of the mandibles. 

 montandoni, Tourn., is without the bristly hairs on the 

 apical segment, signaticejjs has the 3rd antennal joint equal 

 to the scape and 4th taken together, and vagans, Cost., 

 has the base of the pronotum more or less pale. The 

 white orbital streaks vary so much in extent in different 

 individuals that they would doubtless be liable to disappear 

 in some altogether. 



Sp. (?) (1). In general appearance like the above, but 

 smaller, with 3 short black spines on the anterior meta- 

 tarsus, orbital markings as in that species, visible on the 

 face as well as posteriorly.

I was about to describe this form as new, as the males 

 taken by Mr. Morice with his females are clearly distinct 

 from those of the preceding, but I fail to detect any 

 distinguishing structural character in the £> and knowing 

 how often several species of Pompilus are found together 

 in one locality, I feel that possibly the males are those of 

 a distinct species, and so I refrain from describing either. 



Sp. (?) (2). Very like the above, but with 4 longer black 

 spines in the comb of the anterior metatarsus. Orbital 

 markings only visible as a small spot behind the eye, 

 pronotum sharply angulated, propodeum hairy posteriorly 

 and at the sides, wings very dark ; abdomen with the 

 centre of the 1st and the base of the 2nd segment red, 

 6th segment dorsally with a few rather fine exserted hairs.

Sp. (?) (3). A red-bodied species varying to entirely black, 

 orbital markings just visible, prothorax angulated, poste- 

 riorly, propodeum hairy at the sides posteriorly, 5th ventral
