OF WASHINGTON, VOLUME XI, 1909. 67 



Mr. Banks spoke of adopting the superfamily system for 

 the spiders, which in his opinion showed the relationships to a 

 better advantage, and gave an arrangement of the families in 

 the proposed super families : 



Theraphosoidea (Theraphosidae, Atypidae). 

 Scytodoidea (Scytodidae, Dysderidae, Oonopidx, Oeco- 



bidae). 



Drassoidea (Drassidae, Clubionidae, Zodariidae). 

 Agalenoidea (Agalenidae, Dictynidae). 

 Theridioidea ( Theridiidae, Pholcidae, Mimetidae, Liny- 



phiidae). 



Epeiroidea (Epeiridae, Tetragnathidae, Uloboridae). 

 Thomisoidea (Thomisidae, Sparassidae). 

 Lycosoidea (Lycosidae, Pisauridae, Oxyopidse). 

 Attoidea (Attidae, Lyssomanidae). 



Mr. Schwarz made some remarks on the twig-girdling long- 

 icorn beetles of the tribe Onciderini. He said that hitherto the 

 habits of only a few species were known and these all belonged 

 to the genus Oncideres or to very closely allied genera. He 

 now exhibited specimens of Ecthoca quadricornis Oliv.. from 

 Trinidad, W. I., sent in by Mr. J. H. Hart, together with a 

 cacao twig girdled by the adult beetle. This genus is remote 

 from the genus Oncideres and may indicate that the whole tribe 

 possesses the habit, in the adult stage, of girdling twigs. 



Mr. Schwarz added that, since the cacao and various species 

 of rubber trees are being extensively cultivated in Central 

 America, we may expect that quite a number of native insects 

 will attack and injure these trees. He mentioned as an example 

 that the Bureau of Entomology had recently received from 

 Central America the larvae of two species of native Buprestidae, 

 Euchroma goliath and Colobogaster cyanitarsis, with the state- 

 ment that these insects were injurious to rubber trees.
