398 MODERN CLASSIFICATION OF INSECTS. 
1. f. 5.). In addition to the numerous memoirs upon various species 
of this family contained in the general works of Réaumur, Sepp, 
Admiral, Harris, De Geer, Lyonnet, &c., reference must also be 
made to M. Audouin’s Memoir on Dosithea scutularia above referred 
to, and to a memoir by Ver Huell, on the anomalous structure of the 
hind pair of legs in this species, contained in the Tydschrift voor 
Natuurlijke Geschiedenis, 11se deel. 3de stuk. 
Of the relations of these insects but little can be said. The larger 
species, with feathered male antennez, as Latreille long ago remarked, 
exhibit so strong a relation to some of the Bombycide, that it would 
be rash, looking at the imagines alone, to assert that the relation was 
not one of affinity. On the other hand, we have seen them nearly 
related to the Noctuidae. Mr. Curtis proposes to divide these insects 
into two families, characterised by the structure of the male antenne ; 
but such a step would unnaturally break many strong relations, as 
pointed out by Mr. Stephens. (J/lustr. iil. p. 143.) Platypteryx * (fig. 
109. 14. Pl. falcataria) constitutes a most anomalous group, which, 
in the imago state, seems to be one of the types of form of this 
family ; but its larvee (fig. 109. 13. larva of Pl. lacertula) are altogether 
distinct, and more nearly resemble those of Cerura; but this rela- 
tion is so slight, that Latreille has evidently confounded a relation of 
analogy with one of affinity in uniting them into one tribe, Aposura. 

The eleventh family, PyraLip#, is one of moderate extent, and 
the species are of a small size, having the body slender and elon- 
gated; the antennz simple, or but slightly ciliated in the males; the 
labrum and mandibles small (jig. 110. 6. these parts in Crambus 
(Lyndia) Cannarum Sav. Egypt); the labial palpi (fig. 110.8. labium 
of the same) often greatly elongated and porrected, but occasionally 
recurved, with the maxillary ones occasionally developed (fig. 110. 3. 
m. p.; fig. 110. 4 ;—5. and 7. head and maxillz of Cr. Cannarum) ; the 
maxille themselves are generally of moderate length (fig. 110. 7.), 
although in Hydrocampa very small, and in Aglossa nearly obsolete ; 
the head (fig. 110. 3. head of Botys (Ismene) pelusia Sav. Egypt. 
sideways; 4. maxilla, labium, and labial palpi of the same) is occa-
