ZOOLOGY.

creeps out of the chrysalis by a slit taking place down 

 the back. 



The abdomen is almost throughout covered with hair, 

 which is indicative likewise of a strong mucous secretion. 



They take in their fluid nourishment by suction, but 

 the mechanism by which this is effected is not yet 

 known, as from the jaws themselves forming the proboscis, 

 there can be no suckers lodged within the latter that 

 might act. It is probably effected by expansion of the 

 abdomen taking place during respiration. Their deglu- 

 tition would be therefore a respiratory act. 



Besides their very non-artistic webs, no artistic instincts 

 are to be observed in this order. The ova are just layed 

 without more ado upon plants, and rarely upon other 

 objects. The Butterflies are generally related to the 

 plants, and especially to their corollas, whose colours and 

 forms they carry in themselves. 



They divide according to their proximal orders into 

 three families. 



Fam. 1. Dipteroid Lepidoptera, Moths. 



Antennae filiform, wings mostly thrown like a mantle 

 round the body ; proboscis short. 



Small and nocturnal in their habits, proceeding from 

 tolerably apodal Caterpillars, which reside mostly con- 

 cealed in plants, or make themselves cases of hairs and 

 leaves. 



Alliance L Typical Moths, Tineida. 



a. Typical Tineidae : Alucitidae. 



b. Pyraloid : Tinese. 



c. Tortrix-like : Crambidae. 



Alliance 2. Bombycoid Moths, Pyralidce.

b. Typical : Hydrocairmse. 



c. Tortrix-like : Deltoiaes or Hermmise. 



Alliance 3. Homalopteroid Moths, Tortricidcc, 



a. Tinea-like : Fruit -Tortrices. 



b. Pyraloid : Heterogenese. 



c. Typical : Leaf-rolling Tortrices. 



Fam. 2. Hymenopteroid Lepidoptera, Silk- Spinners. 



Antennae filiform, wings tile-shaped. 



Lepidoptera of considerable size, proceeding out of
