Eggs spherical. Larva, in form, highly modified, compared 
with that of Micropteryx, with large, four-jointed antenne and 
very large three-jointed maxillary palpi; no spinneret? No 
abdominal legs, their place supplied by a pair of tubercles 
ending in a curved spine on segments 1-8; a sternal sucker at 
the end of the body. Pupa libera? 
Sub-order IJ. LEPIDOPTERA HAUSTELLATA.? 
This group may be defined thus: Maxille with no lacinia, 
the galee being highly specialized and united with each other 
to form a true tubular haustellum or glossa, coiled up between 
the labial palpi. The maxillary palpi large and fine or six- 
jointed in the more generalized forms, usually vestigial or 
entirely wanting in the more modern specialized families. 
Mandibles absent, as a rule, only minute vestiges occurring in 
the more generalized forms. Wings both jugate and frenu- 
late, but mostly the latter, tending to become broad 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 mesothorax ; the 
abdomen in the generalized forms elongated, and with large 
exserted male genital armature. 
Pupa incomplete, the abdominal segments 3 to 6 or 7 free, 
in the more generalized primitive forms, the end of the maxil- 
lary palpi forming a visible sub-ocular piece or “eye collar;” 
or à flap-like piece on the outside of the maxille; the labial 
palpi often visible ; clypeus and labrum distinct; paraclypeal 
pieces distinct; no cremaster or only a rudimentary one in the 
generalized primitive forms. 
Larva with usually a prothoracic or dorsal chitinous plate; 
the armature consisting, in the primitve forms, of minute one- 
haired tubercles, the four dorsal ones in a trapezoid on abdomi- 
nal segments 1-8, becoming specialized in various ways in the 
later families into fleshy tubercles, or spines of various shapes. 
Five pairs of abdominal legs, with hooklets or crochets forming 
2 If the term haustellata should be thought inapplicable from its frequent use 
by former authors, the term Lepidoptera glossata could-be used instead,
