Hymenoptera aculeata collected in Algeria: the Sphegidae. 129 
ties, with definable colour-differences, and obviously dis- 
similar apices to the g antennae, are in all probability 
really distinct; and that, for the present at least, it is 
safest to call them by separate names. 
The accompanying figures, or rather “silhouettes,” of 
the apices of the f antenna in antennatus, hemixanthopterus, 
and claripennis (placed as nearly as I can manage it in 
the same position and viewed from beneath) are obtained 
by photography from actual specimens in Saunders’s and 
my own collections.

Handlirsch (Mon.) mentions this species as unknown to 
him. Mr. Saunders identified the A. E. E. ¢ from com- 
parison with a specimen sent to him as “ galactina” by 
M. Vachal. The $f by Handlirsch’s Table work out as 
pallida, Rad., but they cannot be that species, as (apart 
trom colour-differences) the intermediate femora have 
rather long, sharp and quite conspicuous “ spinulae ” on 
their inferior margin. Dufour’s description, as far as it 
goes, suits them, and his type was an Algerian insect (from 
Ponteba). Mr. Eaton has a note, “ EKyes subolivaceous, 
light markings of the thorax and abdomen ashy blue.” 
(In the latter character, however, there seems to be con- 
siderable variation—some specimens having also a distinct 
tinge of greenish yellow—much as in chlorotica, which 
galactina superficially a good deal resembles.)
