Mr. Meldola exhibited a living Myriopod fSpirololusJ from San Francisco, and 

 eggs of PhyUium pulchrifolmm from Java. 



Mr. Pascoe, referring to an observation by Mr. F. Walker in " The Entomolo- 

 gist," that the Fire-flies (Luciola italica) seen in abundance in Italy, had probably 

 entered that country from the East, and were hindered by the Maritime Alps from 

 occupying the Mediterranean coast of France, remarked that he had seen the insect 

 in abundance in France between Cannes and the Var, and wished to ascertain if any 

 Entomologist had noticed it farther westward in France. 



Mr. A. Miiller made some further remarks respecting certain pouch-galls found 

 on the leaves of cinnamon from Bombay, exhibited to the Society in March last, 

 which shewed that the question as to the originators of the pouch-galls could not be 

 settled satisfactorily without further evidence. 



The Rev. Mr. Eaton stated that he possessed a specimen of a Tromhidium 

 which had been taken by Mr. Benjamin Lee Smith in September last, in Spitz- 

 bergen ; and also read a paper on the Trichopterous Family HydroptilideB. 



Mr. A. Gr. Butler communicated a Monograpliic List of the species of the genus 

 Gasteracantha, or Crab Spiders, with descriptions of new Bpecies. 



ADDITIONS AND CORRECTIONS to the LIST OF BRITISH STRPHIDJE. 

 BY G. H. YEERALL. 



Since my last communication to this Magazine (February, 1871) 

 on the British species of SyrpJiidcB, I have observed several additional 

 species, including four new to science, and have a few notes on others 

 for publication. 



1. AsciA QUADEiPUNCTATA, Meigeu. — I am convinced that this is only 



a variety of the species generally cdXlGxlfloralis, Mg., as I have 

 captured the females on several occasions in company with ordi- 

 nary A.floralis in marshy lands. 



2. Stephus cokpusus, Egger. — This species, which I originally added 



to the British list from a specimen caught in this neighbourhood, 

 I now believe to be only a variety of S. aJhostriatus, Fallen ; but, 

 while the typical alhostriatus abounds in some large woods, where 

 the males are most indefatigable hoverers, the typical confusus is 

 more confined to gardens and meadows. 



3. Stbphus nigbicornis. — When at Loch Rannoch in June, 1870, 1 



captured six specimens (4 (J, 2 $ ) of a species which is, without 

 much doubt, the ^S*. obscurus of Zetterstedt's Insecta Lapponica 

 (1838), but as the name obscurus was pre-occupied by Say (1824) 

 for an American species, a new name is required, and I therefore 

 propose that of nigricornis. The species is allied to S. lunulatus,
