The egg, according to Chapman, is «large and spherical«, in 

 confinement as little groups, to the number of twenty-five in all. 



Diagnostic Characters of the Lepidoptera laciniata. — 

 I add the characters of this suborder. Imago : Maxilla with a well deve- 

 loped lacinia and galea, arising as in mandibulate insects from a definite 

 stipes and cardo, the galeae not elongated, united, and differentiated 

 into a haustellum, each being separate from its fellow. The maxillary 

 palpi enormous, 6-jointed; mandibles large, scarcely vestigial, with a 

 broad-toothed cutting edge , and with three apparently functional 

 hinge-processes at the base, as usual in mandibulate insects. Hypo- 

 pharynx well developed, somewhat as in Diptera and Hymenoptera. 

 The 2d maxillae divided into a mala exterior and interior recalling 

 those of mandibulate insects; palpi 3-jointed. Thorax with prothorax 

 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 Micropte7-yx and showing no notable distinction compared with 

 those of that genus ; scales generalized ; fine scattered setae present 

 on costal edge and on the veins. Abdomen elongated, with the male 

 genital armature neuropteroid, exserted, the dorsal, lateral, and sternal 

 appendages very large. 



Egg spherical. Larva in form highly modified compared with 

 that of Micropteryx^ with large 4-jointed antennae and very large 

 3-jointed maxillary palpi; no spinneret? No abdominal legs, their 

 place supplied by a pair of tubercles ending in a curved spine, on 

 segments 1 — S; a sternal sucker at the end of the body. Pupa libera? 



Suborder II. Lepidoptera haustellata^ 



This group may be defined thus : Maxillae with no lacinia, the 

 galeae being highly specialized and united with each other to form a 

 true tubular haustellum or glossa, coiled up between th elabial palpi. 

 The maxillary palpi large and five or six-jointed in the more generalized 

 forms, usually vestigial or entirely wanting in the more modern spe- 

 cialized 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 broad and with highly 

 specialized scales, often ornamented with spots as well as bars, the 

 colors and ornamentations often highly specialized; the thorax highly 

 concentrated, the metathorax becoming more and more reduced and 



4 If the term haiistellata should be thought inapplicable from its use by former 

 authors the term Lepidoptera glossata could be used instead.
