the cocoon not being larger than a small pea, whilst the imago is 
nearly an inch long. 
F. Stein has described the pupa state of Osmylus maculatus (the 
largest British species of the family), which is found in damp earth 
in the banks of ditches; when preparing to undergo its final trans- 
formation, it quits its abode, and creeps up the stems of grass. 
(Weigman’s Arch., vol. iv. p. 332.). 
A. singular genus of minute species, which I first described under 
the name of Coniortes (fig. 65. 1. C. tineiformis), (Proceed. Trans. 
Ent. Soc., July 1834; subsequently figured by Curtis under the name 
of Coniopteryx, Brit. Ent., 528. December, 1834, and by Wesmael 
under that of Malacomyza), appears to me, although placed by Curtis 
and Stephens in the family Psocidz, to belong to the Hemerobiide, 
with which it agrees in its head (fig. 65.2.); 5-jointed tarsi (fig. 
65.7.) ; multi-articulate antenne ; labrum (/ig.65.3.); mandibles (fig. 
65. 4.); and maxille (jfig.65.5.). It differs, however, in the slight 
reticulation of the wings; their white mealy covering (exhibiting no 
appearance of ciliz, hair, or scales); the large size of the terminal 
joint of the labial palpi; the obsolete labium (ligula) (jig. 65. 6.) ; 
the absence of tibial spurs; and the smaller size of the posterior 
wings. The species sit with the wings deflexed, and feign death by 
bending their antenne under the body. Mr. Curtis has figured a 
singular larva (jig. 65.8.) belonging to this genus, communicated 
by Mr. Haliday, who thinks it is probably aphidivorous, and enter- 
tains no doubt that it is the larva of C. tineiformis. He says its 
general character is closely allied to the larva of Hemerebius, but 
the structure of the head appears to me to be very different. The fol- 
lowing note has been since kindly communicated to me by the latter 
gentleman. “ Coniopteryx tineiformis, when preparing for trans- 
formation, spins an orbicular pouch of fine white silk of close texture 
generally on the trunk of a tree, in chinks of the bark, or among moss, 
The pupa is quiescent (fig. 70. 1.)” 
The family Sraripa * Leach consists of a few species of moderate 
or large size (fig. 64. 10.—22. Sialis lutaria, and details), constituting
