recognizable type. Gular sutures not confluent. Pleural sutures 

 of prothorax distinct. Antennae variously constructed. Tarsi 

 with variable number of joints (five to one), exceptionally hetero- 

 merous, but then only in one sex. Testicular follicles sessile. 

 Male genital apparatus with two or three pairs of accessory 

 glands (ectadenia and mesadenia). Four or six Malpighian 

 vessels. Larvee campodeiform or derivative therefrom ; ortlio- 

 or hypo- or pseudortho-gnathous ; sometimes without legs ; 

 generally straight, seldom with curved body, like the cockchafer 

 grub.

3. Family-Series Heteromera. 



Wing-venation of the third type. Gular sutures not con- 

 fluent. Pleural sutures of prothorax distinct. Antennae gene- 

 rally simple, more rarely serrate, pectinate or flabellate, or 

 with thickened club-iike ending. Tarsi heteromerous, five- 

 jointed in the front and middle legs, four-jointed in the hind 

 pair. Testicula,r follicles sessile. Male genital apparatus with 

 two or three pairs of accessory glands (ectadenia and mesadenia). 

 As a rule six, exceptionally only four, Malpighian vessels. Larva? 

 hypognathous ; generally with short legs.

4. Family- Series Phytophaga. 



Wing-venation of the third type. Gular sutures not confluent. 

 Pleural sutures of prothorax distinct. Antennae generally simple, 

 less often serrate, pectinate, &c., or with thickened terminal 

 joints, very rarely irregular. Tarsi crypto-pentamerous, i. e. 

 five-jointed, with the fourth joint very small, firmly united with 

 the fifth, and sometimes very indistinct, the first three joints 

 with broad sole ; rarely distinctly pentamerous and simple.
