NEW BRITISH SPECIES NOTICED IN 1856. 75 



gulata, Erich.; Kaf. d. Mark Brand, i. 360, 11 

 (1837) ; Gen. et Spec. Staph. 175, 35 (1839). 

 Taken by myself at Hampstead in November, 1855, and 

 subsequently at Highgate in nests of Formica rufa; Mr. 

 Waterhouse has likewise met with it under similar circum- 

 stances near Erith. 



Genus HOMOEUSA, Kraatz, Naturgesch. d. Insect. 

 Deutschl. ii. 76 (1856). 

 This genus, recently established by Herr Kraatz on the 

 species which follows, and which had previously been located 

 in Euryusa, may be at once distinguished by its pentamerous 

 anterior tarsi, broader form, the acutely rectangular posterior 

 angles of the thorax, and the abdomen narrowed from the 

 base to the apex ; and, furthermore, the ligula and the labium 

 and its palpi, but which I have not had an opportunity of 

 examining, afford important distinctive characters. 



18. Homoeusa acuminata, Maerkel ; Kraatz, Naturgesch. 



d. Insect. Deutschl. ii. 78, 1 (1856). Euryusa acu- 

 minata, Maerkel, Ent. Zeit. Stett. iii. 143, 5 (184*2), 

 in Germar, Zeitschr. f. d. Entom. v. 228, 79 (1844) ; 

 T. V. Wollaston, Zool. 5178 (1856). 

 A single specimen taken by Mr. Wollaston in a nest of 



Formica fusca, beneath a stone, near Bromley, Kent. 



Having recently received from Herr Maerkel an example 



of his E. acuminata, and carefully compared Mr. Wollas- 



ton's specimen therewith, I am enabled unhesitatingly to 



pronounce their specific identity. 



19. Atemeles paradoxus, Grav. ; Kraatz, Naturgesch. 



d. Insect. Deutschl. ii. 116, 1 (1856). Lomechusa 

 paj-adoxa, Erich. 

 A single example found by Mr. Waterhouse at Hamp- 

 stead, in company with Formica fusca.
