THE BRITISH NATURALIST. [December 



This completes our list of Hymenoptera- Aculeata from the counties 

 of Lancashire and Cheshire, so far as observations have been recorded. 

 It is, I trust, only a preliminary one, containing, as it does, but 164 of 

 the 373 species described by Mr. Edward Saunders in his "Synopsis," 

 as indigenous to the British Islands. 



It will be noticed that the records at present are confined to very 

 few and scattered localities ; there is little doubt therefore that the 

 investigation of hitherto unexplored districts will afiord material 

 additions in the future. 



In conclusion, it may not be uninteresting to compare the above 

 results with the two orders of insects of which local faunas have 

 previously been compiled by the Lancashire and Cheshire Entomo- 

 logical Society, viz: — Lepidoptera and Coleoptera, as follows : 



Species recorded 

 from Lane, 

 and Ches. 



Hymenoptera-Aculeata, 164 ; or 44 % of total British species (373). 

 Lepidoptera, ^355; 65 ,, ,, (2,079). 



Coleoptera, 990 ; ,, 30 , ,, (3.227).

OidcematophoFus lithodactyla, Tr.— This widely distributed and very 

 distinct looking species seems fairly abundant wherever its food plant 

 occurs.

 Similidactyla, Dale "Mag. Hist.", VII., 263; Stphs. " Ih.", IV., 375; 

 Stt. " Cat.", 31. There is a great deal of difficulty relating to the 

 synonymy of this species, which appears to be the tesserndactyla oi 

 Haworth and the siuiilidactyla of Dale. Of this I wrote : — 

 Tessevadnctyla is given as British by Haworth, but the species known 

 on the Continent by this name is not a British insect, the name being 

 applied to a species closely allied to gonodadyla . The Linnaean 

 description, " Systema Naturae " (12th edition, p. 900) might mean 

 anything. It is:- 'y4///t:?7<^ ali.s patentibusfissiscinereo-nebulosis ; posticis 

 fusis.' It is Haworth (quoting Fabricius' description) writes : — 'Alis 

 patentibus fissis cinereo-nebulosis, posticis fusco nebulosis,' which is 

 (except the last two words) exactly the Linnaean description ; but 

 Flaworth adds: — 'Habitat prope Londinium at rarissime.' If the 

 Continental lepidopterists are right in their assignment of the correct
