LEPIDOPTERA. — ALUCITID. 413 
I have already (p. 324.) stated the grounds for my opinion as to its 
location amongst the Lepidoptera. My fig. 113.11. represents Acen- 
tropus Garnonsii; 12. the head and prothorax seen sideways, showing 
the tippet ; 13. the palpi, having a minute lateral pair of appendages, 
which I regard as the other pair of palpi; 14. the front of the head, 
distinctly exhibiting a pair of maxille ; 15. the base of the hind wing, 
showing the spring or bridle; 16. scales of the apex of the wing; 
and 17. scales of the disk of the wing. 
Mr. Curtis has described a Lepidopterous insect, supposed by him 
to belong to this family, under the name of Cecidoses Eremita 
(Trans. Zool. Soc. vol. i. pl. 40.), the pupa of which inhabits a gall 
found on a Brazilian shrub. Réaumur has also described a similar gall 
and insect from Cyprus (Mém. tom. ii. pl. 39. f. 1—4:.), but Mr. Mac 
Leay assures me that the supposed galls are in fact the cocoons 
formed by these insects. 
The fifteenth and last family, ALuciTIp#, or the Fissipennes of 
Latreille, is nearly allied to the preceding family, both in respect to 
the elongated form of the body and narrowness of the wings ; but the 
latter, except in one genus, are singularly cleft into narrow feathered 
rays ( fig. 113.18. Pterophorus pentadactylus); the fore wings having 
two, three, four, or six, and the posterior wings three or six of such 
rays, which are beautifully feathered on each edge; they are carried 
horizontally in repose ; the antenne are long, slender, and setaceous ; 
the labial palpi vary considerably in length, being somewhat recurved 
in Alucita, and still less so, as well as much shorter, in Pterophorus. 
The spiral maxille are long, and the maxillary palpi are not evident ; 
in which respects these insects approach the Yponomeutide ( fig. 113. 
19. head of Pterophorus). The legs are long and slender; the fore 
tibiz with one, the intermediate with two apical, and the posterior 
with two apical and two subcentral spurs. 
These insects are of small size; they vary in the time of their 
flight; the Pterophori, being crepuscular, flying over low plants ; 
whilst Alucita frequents our gardens, and enters outhouses, sitting with 
its beautiful fan-like wings. The larvee somewhat resemble those of — 
the Arctiidae, being clothed, although sparingly, with rather long 
hairs, with sixteen feet ; they are very inactive ( fig.113. 20. larva of 
Pteroph. pentadactylus) ; the pupz are variable, being either naked,
