22 HAUSTELLATA. — LEPIDOPTERA. 



Mouffet has admirably delineated the larva of this rare insect, and 

 informs us that in his days it was very common in Norfolk, in Eng- 

 land ; but now both larva and imago are but rarely met with ; the 

 insect is, however, widely dispersed, and one or more specimens are 

 taken nearly annually at Birch-wood, and in the neighbourhood : 

 the male is less frequently observed than the female. From the 

 singular aspect of the larva, Albin termed it the Lobster caterpillar, 

 a name which has since been applied to the imago. " In a wood 

 near Cheshunt."" — Mr. Hatchett. " New Forest, Hants, near 

 Brockenhurst, in July, 1821." — Rev. W. Kirhy. " Near Norwich, 

 once." — W. C. Hewltson, Esq. " Larva near Tunbridge Wells, in

Genus XXXIX. — Notodonta, Ochsenheimer. 



Palpi short, very hairy, biarticulate j basal joint minute, terminal compressed, 

 truncate: maxillce short. Antennce filiform, bipectinatecl in the males, the 

 pectinations short, and nearly vanishing at the apex ; in the females, shghtly 

 denticulated interiorly, and ciliated : head and eyes small ; thorax not crested : 

 abdomen somewhat elongated, robust, subcylindric ; the apex downy : wings, 

 anterior obtuse at the apex, with the hinder margin rounded and denticulated; 

 the interior, or dorsal^ edge, with a projecting tuft of scales in the centre: legs 

 short, robust, densely clothed with scales and hair; the anterior tibice an- 

 teriorly with an elongate lobate appendage; anterior tarsi short, stout, 

 clothed with elongate scaly hair. Larva naked ; with two or more conical 

 protuberances on the back, the anal segment reflected, and bearing two im- 

 perfect prolegs : pupa subterranean, folliculated. 



The genus Notodonta, as above restricted, may be known from 

 the cognate genera by having the anterior wings somewhat rounded 

 at the apex, and very slightly denticulated ; the thorax not crested, 

 the antennae bipectinated in the males alone, and the abdomen 

 slightly elongated. The larvse have several conical protuberances 

 on the back, and the hinder prolegs spurious ; the pupae are subter- 

 ranean and folliculated.
