P. MORDELLOIDEA 



111 the Introduc'tioii to his Catalogue (p. 32) Leng proposed, 

 with great hesitation liowever, a series Mordelloidea composed of 

 the following groups: the Mordellidae-Mordellini, the Mordellidae- 

 Anaspidini, the Anthicidae, the Euglenidae, the Eurystethidae 

 ( = Aegialitidae), the Pedilidae, the Pyrochroidae, the Pj'thidae 

 (with the two genera Salpingus and Rhinosimus included), the 

 Cephaloidae, the Oedemeridae, and, with proper reservation, the 

 Meloidae and the Rhipiphoridae. Here only the Mordellidae-Mor- 

 dellini with the main genera Tomoxia, Mordella, and Mordellistena 

 have been retained in this series, and it is even questionable whether 

 these really may constitute a series as their larvae seem rather 

 closely related to the larvae of several of the melandryid genera. 

 The Mordellidae-Anaspidini together with all of the above men- 

 tioned families from the Anthicidae to the Oedemeridae have been 

 placed in the colydiid association of the Cucujoidea ; and in this 

 association are also placed the Othniidae with the genus Ofhnius 

 and the Boridae with the genus Boros which are closely related to 

 the Pyrochroidae and Pythidae. It is however, possible that the 

 Anaspidinae, Anthicidae, and Euglenidae might better be asso- 

 ciated with the Languriidae. The Rhipiphoridae and the Meloidae 

 constitute, according to the larvae, a separate series, the IMeloidea.

Q. CERAMBYCOIDEA 



The series Oerambycoidea contains only one family, the Ceram- 

 bycidae, which is divided into six subfamilies. Of these the sub- 

 family Disteniinae should probably be given family rank because 

 its larva, except in its general appearance, is very aberrant from 

 the larval types of all of the other Cerambycidae. In fact the
