Mr. W. E. Shuckard’s Descriptions 
The abdomen ovato-conical, attached by a short petiole to the 
thorax, and acuminate at its apex $ , obtuse $ . 
Obs. — This genus is scarcely in its place amongst the Pompilidce, 
but seems osculant between it and the Spliegidce ; yet it may pos- 
sibly constitute a new family with another insect that I possess, 
intermediate between the two, and partaking of the characters of 
both. I have named it in allusion to the extension of its legs. 
Species 1 . Exeirus lateritius, Shuck. Plate VIII. fig. 2. 
Niger, pubescens ; capite, antennis, tibiis, tarsis, abdomineque (basi 
excepto ) lateritiis. $ , (j> . 
Length 12 lines. Expansion of the wings 22 lines. 
Black ; the head of a yellow-red, excepting a small spot en- 
closing the stemmata, and extending to the occiput; the apex of 
the mandibles piceous ; the clypeus, face, and cheeks covered with 
a dense silvery down. 
The thorax very pubescent ; the tegulae testaceous ; the wings tes- 
taceous, their nervures fuscous. The anterior legs entirely, excepting 
the coxae, and the knees, tibiae, and tarsi of the remainder, lateri- 
tious or of a yellow red ; of which colour is also the abdomen, ex- 
cepting the basal joint, the extreme base of the second and third 
joints, and the venter. $ , 2 •

Obs. — I have described this insect, which is unique as Austra- 
lasian in my Collection, to show its wide geographical range. I 
know no other extra-European species of the genus, excepting 
those figured in Savigny’s Egypt.
