H Mr. Children's Abstract of the Characters of 



margin, which when at rest are elevated, and form a 



tooth-like projection on the back. 

 Antenmv bipectinate in the males ; in the females occasionally 



filiform and simple. 

 Antlia very short. 

 Larva naked, with protuberances on the middle segment; or 



with two points or tubercular projections on the anal 



segment; or quite smooth.

* These insufficient characters are given literally from Ochsenheinier. 

 Mr. Stephens, as seen in the synonyrna above, has divided this group into 

 no less than seven genera, the characters of which I shall annex as the 

 species occur on which they are respectively formed, in order that such 

 entomologists as do not possess Mr. Stephens's elegant and important " Il- 

 lustrations" may, if they please, be enabled to adopt his views, and know 

 on what grounds they are established. 



\ NoTODONTA, Steph. 

 " N. Palpi short, very hairy, biarticulate, basal joint minute, terminal com- 

 pressed, truncate; maxillcB short. Anfennw filiform, bipectinated in the 

 males, the pectinations short, and nearly vanishing at the apex ; in the 

 females, slightly denticulated interiorly, and ciliated : head and eyes 

 small ; thorax not crested ; abdomen somewhat elongated, robust, sub- 

 cylindric ; 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 tibiae anteriorly 

 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 

 imperfect prolegs : pupa subterranean, foUiculated." — Steph. Ilhist. 

 Brit. Enl. Haitst. II. 22. 

 Stephens's second species, No. perfusca (B. perfuscus? Haw.), is not no- 

 ticed by Ochsenheimer. 



" Sp. 2. perfusca— ^\. XIV. f. 2. Alis anticis fusco-nebulosis, litur^ baseos 

 anique flavescentibus, strigis duabus denticulatis obsoletis." — Steph. I.e. 

 p. 23. 

 Stephens is not positive that this insect is distinct from Ko. Dromedarius, 

 but is inclined to think it is. It is found near Dublin.
