56 Mr. R. M‘Lachlan’s Monograph of the 
An extremely abundant insect, frequenting running streams 
and also canals, &c., appearing in autumn in immense numbers. 
It is occasionally found on the blossoms of the ivy. 
On the Continent are found other species very closely allied to 
this, but differing greatly in the structure of the appendices. With 
respect to A. destituta, described by Dr. Hagen in Ent. Ann. 
1859, p. 20, I can say with certainty that the type specimen of 4. 
nigricornis, Steph., on the authority of which Dr. Hagen intro- 
duced 4. destituta (considering them identical), is only a small and 
somewhat distorted example of 4. nervosa. I know A. destituta 
of Kolenati only from description. 
2. Anabolia ccenosa, Curtis. 
Limnephilus ccenosus, Curt. (*) Phil. Mag. p. 123, 24 (1834) ; 
Anabolia coenosa, M‘Uach. Ent. Ann. 1864, p. 149. 
Antenne black, with very indistinct paler annulations. Head 
black. Palpi dark fuscous. Prothorax conspicuously ochreous, 
with yellowish hairs. Mesothorax black, ochreous at the point 
of articulation with the scutellum. Anterior wings pale shining 
fuscous, thinly clothed with greyish hairs, and with long black 
hairs on the cubital veins; a slightly paler spot at the arculus; 
neuration slightly darker than the membrane; first apical cell 
longer than the second, obliquely truncated at the base ; second 
and fourth equal in length, straightly truncated at the base ; third 
longer than the second and somewhat acute. Posterior wings 
subhyaline, iridescent, tinged with pale brownish at the apex ; 
discoidal cell extremely long and narrow. Legs fuscous with 
black spines. Abdomen fuscous. In the male the upper margin 
of the last abdominal segment is shallowly emarginate in the 
middle, with a scabrous black protuberance on either side of the 
emargination and a pale space between; app. sup. small, rounded 
and black ; app. inf. directed upwards, the apical portion intensely 
black, the extreme apex obtuse and furnished with obtuse black 
ridges or teeth; penis bright testaceous. 
Expanse of fore-wings 11 lines. 
There were three specimens of this insect in Curtis’ Collection. 
He mentions Scotland as the locality, but at the time of publishing 
his paper in the Philosophical Transactions appears to have 
known of only one example. A male specimen (from which the 
above description has been made) is in Mr. Newman’s'’ Collection, 
and was probably captured by him near Leominster. . 
It differs considerably from the group of A. nervosa.
