Forst., Yerh. Pr. Rheinl., 1862, p. 276. 
Form and characters of Dacnusa, except as to the wings. Head 
transverse ; maxillary palpi 6-, labial 4-jointedo Mesothoracic 
furrows complete, but faintly traced, with an additional medial 
channel ; metathorax short, pubescent. Wings narrow from the 
base as far as the stigma, enlarged and rounded posteriorly ; basal 
areolets very short ; radial ample, cultriform, reaching the tip of 
the wing ; 2nd abscissa not exactly straight ; stigma linear-lanceo- 
late, as long as two -thirds of the radial areolet, confounded at the 
extremity with the metacarp ; it resembles an elongate bladder, 
pale and empty, except a small oval mass of colouring matter 
collected at the base ; recurrent nervure rejected ; radial and anal 
nervures faintly traced ; nervures of the hindwings nearly effaced. 
I possess only the ^ , which has the abdomen oval, somewhat 
depressed, broader than the thorax ; 1st segment narrow, linear, 
twice as long as its width, with distinct spiracular tubercles. The 
singularity of the stigma is not accidental, as one would be inclined 
to suppose ; Forster states that all his specimens, of both sexes, 
were similar in this respect.

rather lighter than the following. Head smooth, shining ; man • 
dibles quadridentate with very small equal teeth, testaceous ; palpi 
testaceous. Antennae slender, much longer than the body, blackish 
with the scape piceous, filiform, composed of 28 cylindrical joints ; 
1st joint elongate, the terminal joint longer than broad. Middle 
lobe of the mesonotum very shining, the two lateral somewhat 
dull; scutellum, metathorax, and 1st abdominal segment beset with 
whitish hairs ; metathorax dull, coriaceous, without a medial 
carina. Wings hyaline ; squamulas testaceous ; radial, intercubital, 
and cubital nervures pale, indistinct ; anal nervure effaced ; ner- 
vures of the basal portion of the wing brown, together with the 
coloured spot of the stigma, the empty part of which is pale 
yellowish. Legs testaceous ; tarsi fuscous at the apex. First 
abdominal segment striolate, the rest smooth and glabrous ; 2nd 
suture almost effaced ; segments 2-3 together shorter than all the 
following ; 4th as long as the 3rd, the rest progressively decreasing 
in length to the extremity. Length, 1 ; wings, 2\ lines. 
I captured a single specimen last year in Cornwall.
