10 HAUSTELLATA. — LEPIDOPTERA. 



with a glutinous substance, and Jines internally with silk : the pupa is brown, 

 and strongly denticulated on the margin of each segment. 



Not uncommon in the south of England at the end of June and 

 beginning of July. " Infests the oaks in every wood and lane near 

 Kimpton." — Rev. G. T. Rudd. " Bottisham, not uncommon." — 

 Rev. L. Jenyns. " Near Deptford, abundantly, in June last." —

Family II.— NOTODONTID^ *. 



Palpi more or less evident, two, rarely four, in number, sometimes elongate, very 

 hairy: maxillw usually distinct, not spiral, resembling two slender filamentous 

 processes. Antennce moderate, more or less bipectinated, especially in the males, 

 or setaceous, frequently serrated or ciUated in the females : body not very stout, 

 the apex of the males tufted ; wings deflexed, entire. Males smaller than the 

 females. Larva sparingly covered with hairs, or naked, greatly diversified in 

 form, frequently with one or more elevated tubercular appendages, the two 

 anal legs sometimes converted into a furcate tail: pupa often folliculated, 

 sometimes subterranean. 



Notwithstanding the abbreviated rudimentary tongue with which 

 the insects of this family are furnished, the general habit, structure, 

 and metamorphoses of the latter present more essential characters 

 of affinity to the Hepialidse than are offered by the Bombycidse, 

 which are usually placed next in succession, from being, in common 

 with the Hepialidse, destitute of that generally important organ. 

 The larvae of this family are mostly naked, or very slightly hairy, 

 and are generally furnished with one or more elevated tubercular 

 points ; they are fleshy, and have in general sixteen perfect legs ; 

 but in some of the genera the two anal ones are transformed into 

 caudal appendages : the pupa is frequently subterranean ; though it 

 is often enclosed in a folliculus, or in a hard case formed of various 

 materials, united by gluten. 



The following indigenous genera appear to belong to this family, 

 and may be discriminated by the subjoined external characters : 



* Many of the species of this family have been frequently arranged amongst 

 the true Le. nocturna ; but they have evidently more affinity to the other Noto- 

 dontidic- than to the Noctua?, both in their larva and perfect states.
