412 MODERN CLASSIFICATION OF INSECTS. 
to be seen. De Geer figures the history of this or a closely allied 
species (Mémoires, tom. i. pl. 26.). 
The species of Euplocamus are the largest in the family, their 
larve agreeing in structure with those of Chilo; but the antenne 
of the males are more or less strongly fasciculated, especially in the 
reputed British species Eupl. Anthracinellus; the typical species of 
Incurvaria Haw. (I. masculella) has also the antenne of the males 
strongly pectinated. The species of Gracillaria Haw. are distin- 
guished by the length of the antenne, narrowness of the wings, and 
great breadth of the cilize of the hind wings. The moths sit in a 
very peculiar manner, with the head greatly elevated, the hind pair 
of legs concealed, and the two anterior pairs extended nearly at 
right angles from the body, the fore leg on each side being hidden 
by the middle leg, which is densely clothed with scales; the larva 
(fig. 113. 8.) of G. anastomosis Haw. (syringella Fabr.?) feeds upon 
the leaves of the common lilac, which it at first mines, and when 
grown sufficiently strong, it rolls up the ends of the leaves into a coil, 
in which it resides. It is very common, and has afforded me the 
means of studying its history as well as that of its Ichneumonideous 
parasites. The late E. W. Lewis also investigated the history of this 
species, and observed, that Pimpla stercorator punctures the roll of 
the leaf in order to dislodge the caterpillars on which it feeds. (Mag. 
Nat. Hist. vol. vi. p. 414.) 
It is in this family that I would, provisionally, place the genera 
Lampronia and Eriocephala, distinguished by their metallic colour- 
ing, the latter of which, in the great length of its maxillary, and the 
minuteness of its labial palpi, noticed by Mr. Haliday, as well as in 
the nervures of its wings (fig. 113. 10.), offers so great an ex- 
ception to the remainder of the order, and approximates so closely 
to some of the Trichoptera. (See anté, p. 324. note.) It is to be 
regretted, that the transformations of this and other equally anoma- 
lous groups have not been observed with sufficient precision. Delta 
(Ent. Mag. vol. i. p. 389.), however, describes the larva of Lampronia 
capitella as somewhat resembling that of Cossus ligniperda, and as 
burrowing into the young shoots of the currant. 
It is in this order, without hesitation, and provisionally also in this 
family, that I include the genus Acentropus, which Mr. Curtis 
regards as Trichopterous, and which Mr. Stephens at first placed 
amongst the Neuroptera, and subsequently amongst the Trichoptera.
