400 MODERN CLASSIFICATION OF INSECTS. 
Tineites in the Régne Animal. The family is here made to comprise 
Linneus’s 12 or 14 last species of Geometre, and the whole of his 
Pyralides, which he characterised ‘‘ alis conniventibus in figuram 
deltoideam forcipatam.” (Syst. Nat. vol. ii. p. 809.) 
Of these species those which compose the genus Hypena and its 
allies are the largest in the family, and have the labial palpi greatly 
elongated; the species are found in hedges, and amongst low herbage, 
and the larve are well distinguished by having only three pairs of ven- 
tral feet ; the chrysalis is enclosed in a slight cocoon in a leaf rolled up 
by the larva. (Lyonnet has figured the transformations of several of the 
species P. pinguinalis Linn., &c.) The species of Aglossa, on the 
other hand, are domestic insects, being found in houses, their larve 
feeding upon butter, grease, and other similar substances * ; whilst 
that of Pyralis farinalis Zinn. feeds upon meal, flour, &c. The spe- 
cies of Pyrausta Schr., Pyr. purpuralis Linn., &c., are gaily coloured 
insects, which frequent hedges, and revel in the sunshine, hovering 
over grassy spots, but immediately settling as soon as the sun is over- 
clouded ; whilst those of Hydrocampa and its allies frequent aquatic 
plants, upon which the larvee feed, inhabiting moveable cases, formed 
of portions of the plants; the sides of the body of the larvee in some 
species which reside beneath the surface of the water being furnished 
with elongated filaments (as in some of the Phryganeide ), employed in 
extracting the oxygen from the water. (See De Geer, tom. i. pl. 37.; 
and the Physiological Researches of Dutrochet read before the Aca- 
démie des Sciences upon the subject of these aquatic larve.) Réaumur 
(tom. ii. pl. 32.) and Lyonnet have described the transformations of 
other species, the larvee of which appear to be destitute of these ap- 
pendages. 
I possess some very singular exotic species belonging to this 
family from North America, one of which has the antenne of the 
males elbowed and thickened in the middle (Desmia maculali: 
Westw., in Guér. Mag. Zool. pl. 2.). Another species, apparently 
allied to Hydrocampa, with the labial palpi of the males as long as 
the body, the basal joint porrected, and the two others thrown over 
the back, has been figured by Poey ( Cent. Lepid. Cuba, pl. 8.) under 
the name of Mastigophorus Parra; the same author has also figured 
the transformations of Pyralis hyalinata Linn., a species remarkable 
* Linneus adds, “ In ventriculo humano larva pessima expellenda infuso lichenis 
cumatilis.” (Faun. Suec. p. 351.) Other instances of larve inhabiting, accidentally, 
the human intestines, have been already noticed in this work.
