II me parait hors de doute que la classification de ees animaux 

 doit se réaliser entre les Tortricidae et los Tineidae. Mais leurs ailes 

 postérieures n'ont qu'une seule veine anale, et lenr frange n'est niüle- 

 ment bien développée, ce qui du coup ne nous permet pas de les in-

clure ni dans une famille ni dans l'autre. Pour cette raison je propo- 

 serai la nouvelle famille : Cecidosidae. 



Cecidoses eremita. Cec. cinereus : alis anticis satúrate brunneo-macti- 

 latis, dense ciliatis ; posticis albidis. Hab. prope Monte Video. Pupa in gallis 

 Celastro abscondita. 



From tlie stoutness of tlie body I am inclined to think that this moth is 

 one of the Tortricidae, but it may perhaps belong to the family of Pi/ra- 

 lidae or to that of Crambidae; if so, however, one would expect to tind 

 tlie palpi more strongly developed, but I liave not been able to discover 

 either them or the maxiUae. Although not analogous in its eecononiy, it may 

 be bere remarked that the maggot so often met with in apples is one of the 

 Tortricidae, and that there are many of the Tineidae that leed only on the 

 parenchyma of plants. 



The recorded instance of a similar oceurrence to which I have referred 

 above is that of an insect described and flgured by Reaumur, which evi- 

 dently belongs to the same group as tlie Cec. .Eremita. This may be regar- 

 ded as a most interesting coincidenee, because Reaumnr's insect was a na- 

 ti^e of the Isle of Cyprus. It difl'ers, however, from the South American 

 one in soine material points, wliich I símil briefly notice. 



Reaumnr's insect í'ormed galls, on what he terms a species of Linioniuní . 

 about the size of those of Cec. Eremita; but although they lia ve a sort of 

 little head or crown opposite to the stalk, no mention is made of an oper- 

 culum. In bis figure 1 a circular space is marked, and there is either a 

 small excrescence in the centre, or the pupa is represented stieking out. 

 This acute observer never saw the Caterpillar alive, but he has no doubt of 

 its piercing the gall to allow of the subsequent escape of the nioth. The ca-
