NEW BRITISH COLEOPTERA SIXCE 1839. 127 



scribed a species of Ilisteridce under this specific 

 title : should my conjecture prove correct, we have 

 here not only a species but a genus new to the British 

 list. Plegaderus vulneratus, Kug. [Ulster vulne- 

 ratus, Kugel. in Illig. Kaf. Preus., 62, 18 (1798)]. 

 H. vulneratus, var. b. Gyll. Ins. Suec, i. 97, 29 

 (1808) ; Panz. Faun. Ins. Germ. Fas. 37, tab. 6 

 ,(1797). Plegaderus vulneratus, Eric, in Klug.

 Zool., p. 4196 (1854) ; Murray, Cat. Scot. Col., p. 32 (1853),

Observation. — Mr. Wollaston, Insecta Maderensia, 

 p. 107 (1854), adopts for this insect and its allies 

 the generic title Acratrichis, published by Motschul- 

 sky in 1848 ; I refer the student to the reasons there 

 adduced for the change thus made in strict con- 

 formity with the laws of nomenclature, and for ample 

 generic details.
