CLASSIFICATION OF COLEOPTERA. 261 



Testicular follicles rounded and pedicellate. Male genital appa- 

 ratus with only one pair of simple or forked accessory glands 

 (ectadenia). Six Malpighian vessels.* Larvse hypognatbous or 

 pseudorthognatbous (Cerambycidse), witb somewhat short, short 

 or rudimentary legs, or without legs. 



Families : Cerambycidae, Chrysomelidse, and Bruchidse. 



5. Family- Series Rhynchophora. 



Wing-venation of the third type, or approximating to the 

 second type.t Head generally elongated and snout-like. Gular 

 sutures confluent. Pleural sutures of protborax gone. Epimera 

 united behind the prosternal process. Antennae straight, or 

 with elongate first joint and geniculate, the end joints then 

 thickened and claviform. Tarsi crypto-pentamerous, and only 

 exceptionally distinctly five-jointed, sometimes, as in the Proter- 

 rhinidse and Aglyceridae, which probably belong to this group, 

 crypto- tetramerous or trimerous. Testicular follicles rounded, 

 pedicellate. Male genital apparatus with variously differentiated 

 accessory glands. Six Malpighian vessels. Larvae hypognatbous ; 

 with short legs or without legs ; eruciform. 



Families : Anthribidae, ? Proterrhinidae, ? Aglyceridse, Bfen- 

 thidae, Cureulionidae, Ipidae (= Scolytidae). 



6. Family- Series Lamellicornia. 



Wing-venation of the third type, or by means of reduction 

 approximating to the second type. Gular sutures separated. 

 Pleural sutures of protborax distinct. Antennae with highly 

 differentiated club. Legs highly differentiated ; the front pair 

 generally, by the structure of their tibiae, adapted for digging. 

 Tarsi five-jointed, quite exceptionally four-jointed. The front 

 tarsi in many Coprophoga wanting in both sexes or in the male 

 only. Testicular follicles rounded and pedicellate. Male genital 

 apparatus with only one pair of accessory glands (ectadenia), 

 exceptionally (Cetonia) with three pairs (one pair ectadenia and 

 two pairs mesadenia). Four Malpighian vessels. Larvae hypo- 

 gnatbous, generally without ocelli, with thick curved body, and 

 with legs. 



One family : Scarabaeidae. 



Not long after this classification was published, Ganglbauer 

 had to reconsider the position of the family Hydropbilidae, and 

 he decided to withdraw it from the family-series Diversicornia, 



'-'= According to L. Dufour, Donacia forms an exception with only four 

 of these vessels, and other exceptions will probably be made known when a 

 suf&cient number of the more primitive forms have been investigated. 



t An obvious misprint, which I have corrected, occurs here in the 

 original, the 2 and 3 being interchanged. It is copied by Grobben in his 

 edition of Claus's ' Lehrbuch der Zoologie.'
