NEW FOSSOMAL HYUENOPTERA. 1)/ 



species at Weybridge, in 1845, and described it in the Zoolo- 

 gist, vol. iv. 1157, as A.jaculata. I supposed it to be a new 

 species; but on obtaining the sexes of A. stigma from France, 

 I find it to be the female of that species ; the male has not 

 been met with in England. 



Genus Trypoxylon, Latr. 



4. Trypoxylon attenuatum, Smith ; described in the 

 Catalogue of British Hymenoptera, App. 120. I received 

 the species from Bristol, where it appears to be abundant. 



Genus Ceratophorus, Shuckard. 



5. Ceratophorus anthracinus, Smith ; described in the 

 Zoologist, vol. ix. App. 126 ; this species I received from 

 Devonshire. 



Genus Crabro, Fab. 

 Crahro interstinctus, Smith ; described in the same page 

 as the former ; the locality is Weybridge. 

 Genus Vespa, Linn. 



6. Vespa arborea, Smith (Zoologist, vii. App. GO). I 

 discovered this species in Yorkshire in 1836. It appears to 

 be a northern insect ; it has been taken in Cumberland and 

 Scotland. M. Saussure has met with it near Geneva. 



Notes on the Myrmicidte and Formicidje. 

 Family MYRMicnxas (Formica, pt. Linn.) 



1. Myrmica scabrinodes, Nylander; very abundant in all 

 parts of England. 



2. M. ruginodis, Nylander ; equally abundant with the 

 former species; this species I believe to be identical with 

 the M. rubra of our lists. 



3. M. lavinod/s, Nylander; not so abundant as the pre- 

 ceding ; found at Shanklin, Isle of Wight ; Weybridge, &c. 



4. J/, (-(cspituin, Latr.; this name appears in the Sys-
