The family Xemopteridae iindudes tin* Spoon-wiiige I La. 'e winy' 
(sul)-family Xemopteriime ) and tlie Thread-winged Lm-ewiiigs (sub- 
family rroeiiiae) wlii(di are the most lannarkable insects in the 
wliole Order Xeuro])tei’a. They ]-ange from the Mediterranean 
FegFrn down to South Africa and across to India, ^vith an exten- 
sion to Western Australia and across to the dry inland ]mrts of 
Queensland. Only a singly species, Croce (fttniHafd Frogg., is 
far known to reach to Queensland; hut Western Australia possesse^J 
S})ecies of hotli snl)-famili('s, tiie Xemopterinat' being r(‘])resejitcd 
there by the fine sj)ecies Chu.^moplcra Initti WT'stwood, found around 
Perth and Guildford. 
The Sjioon-wing'ed lacewings have their hindwings (?f most 
cx.ti aordinary form. The l)asal ]H)rtioii is narrowed and lengtlnmed 
into a slender stalk ]irovided with only three main v(dns, Se., R. and 
M. Distally, this stalk widims out into an irregularly dilated area 
with oblique lateral veins on eitlun- side; at some point within this 
area, Rs comes off from R., lieing marked by a stout bbli(}ue rein, 
and junctions with NQ contimung straight on below R . Tlsc 
dilatation is usually constricted near the middle so as to form two 
distinct lol)es of more or less iriegular form, and the narrow piece 
betwe('ii tliem is generally more or less twisted round upon itself, 
so that the two expanded portions do Jiot lie in the same plane. 
A magnificent ncAv species of the genus CJtasmoptcra, discovered 
at Cimderdin, W.A., has been sent me for description through the 
kindness of Mr. L. Glauert, Biologist of W.A. Museum, Perth. 
Tt is distinguislied from C/i. MitU Wwd., l)y its much larger size, 
paler colouration, and particularly by tlie immense length of the
