APPENDIX. 



I have unfortunately very little to add of new infor- 

 mation from Britain about the saw-flies ; but since the 

 publication of Volumes I and II great attention has 

 been paid to them by several diligent students on the 

 Continent. Brischke has added greatly to our knowlege 

 of the life-histories of the Tenthredinides ; to von Stein 

 we owe many excellent papers ; while Pastor Konow 

 has revolutionised the classification by creating a large 

 number of new genera, besides limiting the older ones 

 in conformity with these new ideas, after the analytical 

 method now so prevalent. 



TENTHREDINIDES. 



So far as regards our species the only new genus 

 erected by Konow is Rhogogastera, but he also has 

 formed a genus Enearsioneura for Macrophya Sturmi, 

 Klug. I have given Konow's definitions for our genera. 



Tenthkedo (B. E. Z., xxvii, 236). 



Eyes strongly converging beneath, reaching to the 

 base of the clypeus ; frontal area distinct, furrowed 

 down the centre. Antennal joints becoming attenuate 

 towards the apex. 



Our species belonging to Tenthredo as thus limited 

 are —
