530 Mr. E. Saunders on Hymenoptcra Aculenta: 
the centre by a distinct parting; its sculpture hidden, as is that 
of the thorax ; abdomen pale testaceous. The apices of the segments 
almost colourless and subdiaphanous. All the segments are more 
or less clothed with silvery adpressed pubescence, and there is 
a band of similar pubescence at the apex of each ; according to the 
position the insect is held in, these silvery patches of pubescence 
form different patterns ; beneath with the 2nd, 3rd and 4th segments 
densely clothed with silvery hairs. 
Long, [about 5 or 6 mm.].

Closely allied in general aspect to pictus, F., but with the 
abdomen (at any rate in the specimens before me) entirely rufo- 
testaceous, showing in one specimen only any signs of flavous mark¬ 
ings, and having the apex concolorous (not black as h\ pictus). The 
most important character, however, by which it may be known from 
the above-mentioned species is the form and number of the spines on 
the front metatarsi. These are inconspicuous, only six in number, 
fine, irregular in size and length, and four only of them more or less 
dilated, whereas in pictus they are seven in number, all thick and flat, 
and form a very regular and conspicuous comb. The front femora 
are less dilated, and the intermediate metatarsi are less curved and 
more slender than in pictus. The propodeal area is much more finely 
rugulose, and its sides more finely and densely strigose. The first 
segment of the abdomen also, though finely rugulose, lacks the 
distinct puncturation which exists on that segment in pictus. 
Long. 6-6i mm. 
Unfortunately Mr. Eaton met with males only of this 
species.
