Ethiopia, Mr. Saunders’s determination of it was inevitably 
conjectural; but the insect clearly belongs either to that, 
or to some nearly-related species as yet unknown at any 
rate to the Palaearctic Fauna, such as calopteryx, Handl. 
(from India). It may be desirable, therefore, to give some 
description of its main characters. (Its general appear- 
ance is quite that of atropical,rather than ofa Mediterranean 
insect. ) 
Comparing it with Handlirsch’s Analytic Tables one 
arrives without hesitation at the dichotomy calopterys or 
poecilopterus, but there hesitates because the former is 
called “Species orientalis,” and the latter (‘Species 
africana”) has the propodeum red, while in this specimen 
the “triangular area” at least is black! Such a character, 
however, cannot be thought to be conclusive: and even if 
it holds in the $ ?, the ¢ may differ. 
The head is more or less like those of melanopterus and 
tridentatus, the eyes converging somewhat similarly, and 
the apex of the clypeus folded in at its sides, so as to 
embrace the labrum, as in those species. But the clypeus 
appears decidedly less elongate; and the eyes approach 
much nearer to the posterior ocelli—the interval being 
much less than that which separates the latter from the 
anterior ocellus, or from one another. The neuration is 
just as in the above species (1st cubital cell very narrow 
above, etc., etc.). The insect is entirely without yellow 
markings, and is black only in the neighbourhood of the 
ocelli, on the triangular area of the propodeum, and (more 
or less dilutely) on some of the dorsal abdominal segments. 
Its general colour varies between two reddish shades, one 
lighter, the other darker. The antennae are subclavate, 
the 3rd joint hardly as long as the two following together, 
the apical joint about as long as the 12th much curved and 
sharply truncate. The head round about the ocelli is 
rather tumid and glabrous; but below these swollen areas, 
the face is somewhat impressed, and covered with beautiful 
silvery flat-lying hairs. The convex clypeus is separated 
from the bases of the antennae by a subtriangular “ tecti- 
form” area (so raised centrally as to appear carinated). 
The pronotum is almost without sculpture; the mesonotum 
closely and rugosely punctured, the scutellum finely and 
sparsely so; the propodeum has much larger punctures, 
very sparse in the middle, but becoming dense and even 
rugose on the sides. Behind, the propodeum is not
