Tribe TRYPRONIDES. 



Recent authors have subdi\ided this division, regarded by 

 Holmgren as of equal rank with the Metopiides (his Aspidopi) 

 Bassides (his ScHizoDOXTi) aud ExocHiDES (his Pnosopi), intJ 

 sections vvnich they consider as distinct from each other as from 

 Holmgrens other sections; but this I think incorrect. The 

 whole conformation of the above four great divisions is so 

 dissimilar that they are distinguishable at a glance, \Yhereas the 

 distinction between the Mesoleptini and Tryphonini is Jio more 

 than the comparative sessility of the abdomen, and a distinct line 

 cannot be drawn in this respect; these two diifer from the 

 CTEKOPELMi>fi solely in the absence of tarsal pectination ; and all 

 three are nearly indistinguishable from the Cteniscini, exceptino- 

 in the conformation of their calcaria ; they have a common 

 hacies, and all, I believe, prey upon Sawflies. Hence I prefer to 

 retain them under a common head, Homalopi or Trypuonides.
