70 Mr. R. M‘Lachlan’s Monograph of the 
Head, prothorax and mesothorax castaneous, the prothorax with 
long brown hairs. Anterior wings shining brownish-testaceous, 
darkest towards the dorsal margin, the apical edge narrowly fus- 
cous, the hairs springing from the granulations black, and there 
are long black hairs on the veins towards the dorsal margin; veins 
fuscous; three small whitish spots, one at the base of the third 
apical cell, one at the thyridium, and the third below it at the 
arculus. Posterior wings hyaline, testaceous towards the apex, 
and with brown veins. Legs testaceous, with black spines. Ab- 
domen fuscous above, reddish-ochreous beneath. In the male 
the app. sup. are very large, foliaceous, angular, cut off very 
obliquely beneath, testaceous, the lower margin fuscous; app. 
intermed. short and broad, triangular, concave internally, united 
at the bases, the apical portion intensely black; app. inf. very 
short, obtusely pointed. The female appears to be furnished with 
large obtuse superior valves, and lateral valves of about the same 
breadth and length. 
Expanse of fore-wings 10 lines. 
I am only acquainted with four British examples of this sin- 
gular insect; one in Curtis’ Collection, of which I know not the 
locality ; two in my own Collection, taken by Mr. Fereday at 
Scarborough, in September, 1862; and one taken by Mr. B. 
Cooke at Bowden, Cheshire. 
Genus CuzrTorTeryx, Stephens. 
Antenne slender, basal joint stout, slightly curved, a little 
longer than the head. Head transversely quadrate, with a few 
long scattered hairs. Maxillary palpi in the male with short 
broad basal joint, two succeeding joints of nearly equal length, 
the second shorter than the third; in the female the basal joint is 
short and stout, second, third and fourth joints about equal in 
Jength and thickness, terminal joint rather longer and thinner. 
Labial palpi with the three joints of nearly equal length, first and 
second broad, third narrower. Prothorax distinct, hairs few and 
long. Mesothorax slightly broader than the head, subrotund, 
with a broad flat space above. Anterior wings very short, narrow 
at the base, expanding greatly towards the broadly rounded apex ; 
costa much arched; almost the whole of the membrane is thickly 
covered with very distinct granulations, from each of which springs 
a long erect bristle-like hair; marginal cilia rather long, cubital 
veins with very long erect hairs; neuration very strong, radius 
not deeply bent before the termination, discoidal cell long and 
narrow, apical cells short and broad. Posterior wings hyaline,
