the Xcoclytarlus many individuals emerged of an immigrant 

 Honniopfents (Braconidae) described on another page as 

 H. ragrans. This species attacks the larvae of the Neoclytar- 

 his while feeding near the surface and the full grown larvae _ 

 spin their cocoons in a mass in the horings of the beetle, emerg- 

 ing through a circular emergence hole. This species is gen- 

 erally distributed in the lowlands of Oahu. 



From the material of Euphorbia attacked were found num- 

 erous examples of the immigrant Bethylid Sclerodermus immi- 

 gnms Bridwell Avhich furnished the material for the further 

 studies upon this species published on another page of these 

 Proceedings. 



There was also found attached to this species a large 

 species of Eupelmus, apparently endemic and nndescribed. 



Xcoclytarlus euphorbiae readily oviposited and bred in the 

 wood of the native species of Euphorbia so that a constant and 

 dependable supply of larvae was ol)tained for use in the 

 studies made of the biology of the species of Sclerodermus. 



This species is the first characteristic species of the group 

 called Clytarlus by Dr. Sharp in the Fauna Hawaiiensis 

 of wliich th(^ food plant is known which is not attached to one 

 of the legumes, Acacia Icoa or Sophora chrysophylla. 



Tlie name Clytarlus will unfortunately have to be given 

 u]) fiir this genus since none of this group were included under 

 the name in the first paper (Trans. Ent. Soc Lond. 1878:206) 

 in which it was employed, the only species there included 

 being Clytarlus roJnistus y^\\iu-\)=Pl(H/if]nui/sus pulreriilentus 

 Motschulsky, the ty])e of the genus l^hif/ifhj)n/su''< and cris- 

 fatus Sharp since referi-ed by Dr. Shar]i to CallUh'Un/sus. Tn 

 order to avoid any further shifting of names, the former species 

 may be designated as the type of Clytarlus Sliar]) 187S and 

 being thus isogenotypic with Plagithmysus^ this genus must 

 fall as a pure synonym. Clytarlus Sharp 189G Avith fragilis 

 as Ty])e thus is without a name and for it NeocJytarlus is 

 suggested. Aurivilius in Coleop. Catal. 29:387, 1912, has 

 merged all the Plagithmysine genera of Sharp into Plagithmy-
