18 “Rev. T. A. Marshall’s Monograph of 
except the last and the hypopygium, which are rufous. Terebra 
exserted, curved upwards. 4 similar, according to Nees, but not 
described. Length, 14 lines ; exp., 3! lines. 
I have taken two females of this species, one in 
England, the other in France, at Nantua; they agree in 
all respects except size, the English example being much 
the smaller. Fora iong time I supposed them to be 
D. postica, Hal. (sp. 20), the 2 of which is undiscovered ; 
but the identification is too uncertain to be adopted. 
Taken by Manger in the Sudetsche Gebirge. 
23. Dacnusa aphanta, Marsh. 
D, aphanta, Marsh., lib. cit., p. 488, 2. 
First cubital areolet. more or less confounded with the 1st dis- 
coidal. Black; abdomen piceous; body not very pubescent. 
Head wider than the thorax ; oral parts pale. @ Antenne twice 
as long as the body, blackish, with the scape partly testaceous, 
25-jointed. Mesothoracic furrows obsolete ; a linear fovea before 
the scutellum ; metathorax sloping from the base, not shining, 
bisected by a transverse carina. Wings hyaline ; squamulex pale 
yellow ; nervures and stigma pale brownish; the latter elongate, 
stout, abruptly acuminate at the extremity, emitting the radial 
nervure before one-fourth of its length ; radial areolet large, much 
longer than the ‘prebrachial, dilated and sinuated before the 
extremity ; the nervure dividing the lst cubital from the 1st dis- 
coidal areolet widely interrupted, subobsolete ; recurrent nervure 
interstitial. Legs very pale testaceous, the coxze included ; tips of 
the hind tibize and iast joint of all the tarsi, infuscated. Abdomen 
claviform, as long as the thorax, somewhat compressed towards the 
apex, which is vertically truncate ; lst segment linear, black, 2} 
times as long as its width, hardly aciculate, not shining ; the tuber- 
cles not salient ; the following segments piceous. Terebra briefly 
exserted. ¢ doubtful on account of the antennz, which have 
only 24 joints, and are somewhat shorter than those of the 9°. 
Otherwise it agrees well with the description ; the 1st cubital is 
completely confused with the 1st discoidal; this character may he 
of little value, but I could not find any other by which to fix the 
place of a species so little distinguished. Length, 3 lines ; exp., 
2 lines. 
Taken in 8. Wales and near Plymouth. Forster has 
made a genus Aphanta, possibly intended for this insect.
