one) are narrow and transverse, the 8th especially so, and 
not modified ; the cheliferous segment ordinary, sessile, the 
claws short and stout. In the anterior wings the sub-costa 
extends into the pterostigmatical space, in the posterior it 
is abbreviated; the wings without dark markings. The 
rostrum very short, triangular ; maxillary palpi having the 
3rd and 4th joints very much dilated, and concave within, 
2nd and 5th thin, Ist very short, the others longer and 
subequal ; maxillary lobes narrow, but the inner broader 
than the outer, and furnished with a crest of cilia at the 
tip; labial palpi with the joints short and not dilated, but 
the 2nd slightly clavate; labrum (rostrum) with a deep 
triangular notch at the apex. Tarsal claws simple (not 
serrate), strongly curved. 
_ This genus is, in many respects, intermediate between 
Panorpa and Euphania (Westw.). By its very short 
rostrum and narrow and unmodified penultimate and ante- 
penultimate male segments it approaches the latter, while 
in the form of the wings and in the composition of the 
cheliferous segment it is more allied to Panorpa. In 
Euphania the costal area of the wings is broadly dilated 
and the cheliferous segment bears only modified claws, 
the whole segment being considerably different in structure 
from that of Panorpa. As heretofore, I am inclined to 
consider Huphania identical with Chorista (ilug), though 
Klug neither describes nor figures the dilated costal area. 
If C. australis be not /. luteola, then it is some insect 
that has not since been observed: and I must admit 
that the details of the mouth-parts of C. australis, as 
given by Klug, do not agree with those of 2. luteola, in 
which the maxillary palpi have the 3rd and 4th joints very 
much dilated, as in Panorpodes; but in £. ruficeps 
(Newm.) these palpi are formed much in the manner as 
indicated for Chorista, still, however, with the characteristic 
dilatation of the costal area in the wings. 
P. paradoxa, sp. nov. 
Testaceous. Head shining-black between the ocelli; 
antenne fuscescent, excepting at the base. Legs testa- 
ceous. Wings wholly pale yellowish, shining, without 
markings, only that the pterostigmatic region is more 
opaque and finely granulose; veins pale fuscous, the trans- 
verse veinlets nearly transparent and almost colourless.
