30 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



I feel that I should apologize for reviving these papers, but 

 systematic workers will see that they must be considered and 

 those having access to them should make an effort to identify 

 as many species as possible. 



Considerable discussion followed on the advisability of 

 adopting Rafinesque names. 



A NEW GENUS OF SAWFLIES FROM CHILE. 



[Hymenoptera, Tenthridinida?] 

 BY S. A. ROHWKR. 



Trichotaxonus, new gxmus. 



Belongs to Emphytinas of Dr. A. D. MacGillivray. 



Head, thorax, venter, and legs with long hairs; head transverse, the 

 vertex raised as in many Nematids ; eyes oval, prominent, subparallel : 

 malar space wanting: clypeus truncate, mandibles long, slender; anten- 

 na? 9-jointed, pedicel much longer than wide, but little longer than the 

 scape, third joint longer than the fourth : thorax normal ; basal plates 

 widely separate at apex: abdomen of the usual type: hind basitarsis

 teeth ; anterior wings of the normal type, transverse median in the mid- 

 dle of the discoidal cell : hind wings with a surrounding nervure, no 

 closed discal cells, lanceolate cell petiolate, M.. leaving the anal nervure

Type: Trichotaxonus rccdi Rohwer. 



The male of this genus is unknown, but there can be no 

 doubt that it would be much like the female.

 ing : scutellum with a few large punctures : scutellar appendage polished,
