On comparing Spinola's detailed description of the species 

 which he named intermedia, (and of which he had captured 

 many specimens), with Mr. Wdlker's description of L. dorsi- 

 gera, with which the latter has united it, sufficient differences'^ 

 will be found to warrant their separation ; and the name 

 L. intermedia having been previously employed, I have 

 named it in honour of the celebrated Italian Hymenopterist, 

 by whom it was first described. M. Fonscolombe's descrip- 

 tion of the species which he named L. intermedia, and which 

 is taken from a ? specimen, agrees with Mr. Walker's descrip- 

 tion of L. dorsigera ? ; but not with Spinola's L. intermedia, 

 as used by Mr. Walker without any expression of doubt ; 

 although M. Fonscolombe gives the reference to Spinola with 

 a query, and points out the differences between his own and 

 Spinola's insect. 



^ The different colour of the basal joint of the male antennae, the interrupted 

 anterior yellow margin of the collar in both sexes, the want of the lateral lines at 

 the base of the wings in the female, and the want of the broad fascia on the coxae 

 of L. dorsigera, arc especially observable.
