The pupa . — Unfortunately we are as yet ignorant of the pupa form. Dr. Chapman has only 
found the headpiece of the pupa, but refers it to tlie “ lucompletm/’ and thinks it probable that 
the pupa has the “ third and follo^vdng abdominal segments free.’^ 
The egg . — The egg, according to Chapman, is “large and spherical,” in confinement dei>osited 
in little groups, to the number of 25 in all. 
Diagnostic characters of the Lepidoptera laeiniata . — I add the characters of this suborder. 
Imago: Maxilla, with a well-developed lacinia and galea, arising, as in mandibulate insects, from a 
definite stipes and cardoj the galeje not elongated, nor united and difierentiated into a haustellum, 
each being separate from its fellow. The maxillary palpi enormous, six-jointed; mandibles large, 
scai'cely vestigial, with a broad-toothed cutting edge, and with three ajiparently functional hinge 
processes at the base, as usual in mandibulate insects. Hypophaiynx well developed, somewhat 
as in Diifiera and Hymenoptera. The second niaxilhe divided into a mala exterior, recalling 
those of mandibulate insects; palpi three-jointed. Thorax with pi^othorax very much reduced; 
metathorax very large, with the two halves of the scutum widely separate. Venation highly 
generalized; both fore and hind wings with the internal lobe or “jugum,” as in Trichoptera; 
veins as in Micropteryx and showing no notable distinction compared with those of that genus; 
scales generalized; fine, scattered setm present on costal edge and on the veins; abdomen 
elongated, with the male genital armature neuropteroid, exserted; the doi'sal, lateral, and sternal 
appendages very large. 
Egg spherical. Larva in form highly modified, compared with that of Micropteryx, with large 
four -jointed antenum and very large three-jointed maxillary palpi; no spinneret 1 No abdominal 
legs, their place supplied hy a pair of tubercles ending in a curved spine on segments 1-8; a sternal 
sucker at the end of the body. Pupa liberal. 
Suborder 11 . — Lkpidoptera nAUSTELLAXA.’ 
This group may be defined thus: Maxillm with no lacinia, the galem being highly specialized 
and united with each other to form a true tubular haustellum or glossa, coiled uj) between the labial 
palpi. The maxillary ])alpi large, and five or six-jointed in the more generalized forms, usually 
vestigial or entirely wanting in the more modern s])ecialized families. Mandibles absent as a rule, 
only minute vestiges occurring in the same generalized forms. Wings both jugate and frenulate, 
mostly the latter; tending to become broa<l and with highly specialized scales, often ornamented 
with spots as well as bars, the colors and ornamentation often highly specialized; the thorax 
highly concentrated, the metathorax becoming more and more reduced and fused with the 
niesothorax; the abdomen in tlie generalized forms elongated and with a large exserted abdominal 
male genital armature. 
Pupa incom])l’ete,.the abdominal segments 3 to 0 or 7 free; in the more generalized primitive 
forms the end of each maxillary palpus forming a visible subocular piece or “eye collar” or a 
fiap-like piece on the outside of the maxillm; the labial palpi often visible; clypeus and labrum 
distinct; paraclypeal pieces distinct; no cremaster, or only a rudimentary one, in the generalized 
primitive forms. 
Larvie with usually a i)rothoracic dorsal chitinous plate; the armature consisting in the 
l)rimitive forms of minute one-haired tubercles, the four dorsal ones arranged in a trai)ezoid on 
abdominal segments 1-8, becoming specialized in various Avays in the later families into ileshy 
tubercles or spines of various shapes ; five pairs of abdominal legs, Avith booklets or crochets forming 
a comx)lete circle in the more generalized forms (in Uepialidm several complete circles), the booklets 
ill the later, more siiecialized groujis usually forming a semicircle situated on the inner side of the 
planta. 
This suborder may be subdivided into two series of suiierfamilies and families, the 
FaleoJepidopicra and the Neolepidoptera. 
•If tho term Zvpidopiera hausteUala should he thought inapplicable from the use of the T^ord Hansiellaia for 
haiistellate insects by former authors, the term Lepidoptera glossaia could be used instead.
