442 Morice and Durrant on " Jurinean " Hymenoptera. 



Formicina would doubtless have been described at 

 length by Shuckard in his Elements of British Entomology, 

 but only one part (Coleoptera) was published (in 1839). 

 It is not necessary to discuss the status of " Formicina 

 Shkd.'' as a possibly valid genus, for Wheeler [Ann. 

 NY. Ac. Sc. 21. 164 (1911)] has very properly cited as its 

 Type Foemica rufa L., and has definitely sunk it as a 

 synonym of Formica L. — Emery's subsequent suggestion 

 that flava L. should be regarded as the Type cannot 

 therefore be maintained. 



[It should be noted that ^Formicina Canestrini (1868) 

 Arachn. is homonymous with Formicina Shuck. (1840).] 



The synonymy of Acanthomyops is as follows : —
