(Paper No. 7. — Conclusion.) 

 Family XIV. — Tenthredinid.e. 



This family is probably the most extensive of any of the families of 

 the sawflies, and is of world-wide distribution, representatives of it being 

 found in all parts of the world, although, as a whole, it is more numerously 

 represented in the Palearctic and Neotropical regions than elsewhere. 



I have separated the family into four subfamilies, distinguishable by 

 characters made use of in the following table : 



Table of Subfamilies. 



Lanceolate cell contracted before the middle, but still opeji^ the contracted 

 part not quite extending to or uniting with the submedian vein, and 

 with or without an oblique or straight cross-nervure beyond the middle. 

 Front wings with three submarginal cells. 



Third transverse cubitus wanting, the first and second sub- 

 marginal cells each receiving a recurrent 



nervure Subfamily L, Athlophorinse. 



Second transverse cubitus wanting, the second submarginal 

 cell therefore large and receiving both recurrent 



nervures Subfamily II., Dolerinse. 



First transverse cubitus wanting, the first and third sub- 

 marginal cells each receiving a recurrent 



nervure Subfamily III., Strongylogasterinae (pars). 



Front wings with four submarginal cells, the second and third each 

 receiving a recurrent nervure. .Subfamily III., Strongylogasterinai. 

 Lanceolate cell with a straight or oblique cross-nervure at or a little 

 before the middle ; if contracted, closed, the contracted part extending 

 to and uniting with the submedian vein ; front wings with four sub- 

 marginal cells Subfamily IV., Tenthredininas. 



Subfamily I. — ATHLOPHORiN.t;. 



This subfamily is based upon the genus AtJilophorns, Burmeister, 

 described in 1847, from Java. It is unknown to me in nature, but is
