CHRYSOMELIDiE.

Finally the Cryptostomes are very characteristic, the head being 
bent down so that the mouth is below, the antennae inserted close to¬ 
gether at the front of the head. They include the very distinct Cassi- 
dince in which the head is hidden, and the Hispince, which have a 
characteristic outline and are often spiny. Actually if a Chrysomelid 
has not the narrow prothorax, nor the curved ventral abdominal 
sutures, nor the deflexed head and the contiguous antennae, it must be 
one of the Cyclica , the largest division of this large family.

The following is a synopsis of the larval habits as far as they are 
known :— 
Sagrince. —Hoots of trees. 
Donaciince -—In aquatic plants. 
Criocerince. —-On aquatic plants above water, or on land 
plants with excrement over, 
Camptosomes .—In cases, on plants or in ants’ nests. 
Eumolpince —In roots or in soil.
