132 ARTHROPODA. 



APHIDIPHAGA. Maxillary palpi with the last joint securiform. 

 Antennae short, the last three joints forming a club. 



The bodies of these insects are hemispherical ; they have short 

 legs, and strong powers of flight. They feed on Aphides, both 

 in the larval and perfect states. 



Coccinellidcs (Lady- Cbilocorus. Scymnus. 



birds). Coccidula. Synonycha. 



Epilachna. Cranophorua. Coccinella. 



Exochomus. Ehizobius. Megilla. 



FUNGICOLA. Maxillary palpi with the last joint filiform. An- 

 tennae moderately long, flattened, or with a flattened club. 



The European species only are known to feed on fungi both in 

 their larval and perfect states. Trochoideus has 4-jointed an- 

 tennae. Mycetaeidae contains a number of genera of uncertain 

 affinities. Their tarsi are 4-jointed; nevertheless their nearest 

 allies appear to be the Endomychidae. Orestia is referred by 

 Erichson to the Halticidas. Trochoideus is a very aberrant genus, 

 simulating the Paussidae.

Head not rostrate. 



Maxillae with one lobe XYLOPHAGA. 



Maxillae with two lobes. 

 Antennae linear. 



Body elongate LONGICORNIA. 



Body ovate or round PHYTOPHAGA. 



Antennae clubbed at the end CLAVIPALPI. 



CLAVIPALPI. Last three joints of the antennae forming a com- 

 pressed club. Maxillary palpi with the last joint broadly trans- 



These insects are apparently vegetable-feeders ; they are mostly 

 exotic ; the few British species are found in fungi.
