10 BRITISH GALL-INSECTS. 



X. AULAX. 



28. Sahaudi, H. (Marshall, E. M. Mag. iv. p. 273). Bred. 



29. Brandtii, Ratz. (Marshall, E. M. Mag. iv. p. 274). 

 I do not know this species from autopsy. 



30. fjlechomatis, H. (Marshall, E. M. Mag. iv. p. 274). 



31. hrevlcornis, Curtis, (Marshall, E. M. Mag. iv. p. 



275). 

 Also unknown to me. Potentilla should be examined for 

 this or an allied species. 



32. Bhceadis, Kt, 



Bred from inflated capsules of Pajjaver rhosas et duhiiwi, 

 containing numerous egg-shaped larval cells imbedded in the 

 pith. 



TENTHREDINID.^. 



My collection contains specimens collected in localities as 

 far distant as Devonshire and the Shetlands and from many 

 a county between ; but it is useless to enumerate my mate- 

 rials, owing to the chaotic state of my knowledge of the 

 indigenous forms. Long series of both insects and their galls 

 from different parts and from different willows can alone 

 mend matters; but how can they mend so long as our Ento- 

 mologists do not take to the breeding of the saw-flies as easily 

 as to that of the favourite Lepldoptera ? The iQVf species 

 enumerated below do, therefore, only just help to show, how 

 much there remains to be done ; they are the only ones as 

 yet cleared up out of a number of some thirty unnamed 

 species !
