NEW BRITISH SPECIES NOTICED IN 1859. 113 



The broader form, dark colour and coarse sculpture readily 

 distinguish this species. Sturm's figure is not altogether 

 satisfactory; the thorax there appears widest at the base; but 

 in my specimen its greatest width is at about one-sixth from 

 the base. 



Having on a former occasion given the bibliographical 

 references, I need not here repeat them. I will merely add: 

 Redtenb. Faun. Austr. Ed. ii. 325 (1857). 



24. Olibrus oblongus, Eric. ; Waterhouse, Proc. Ent. 



Soc. 4 April, 1859, Zool. 6614 (1859). 

 Olibrus oblongus, Eric. Naturgesch. d. Ins. Deutschl. 

 iii. 121, 10 (1845) ; Redtenb. Faun. Austr. Ed. ii. 322 

 (1857). 

 Very closely allied to O. piceus, but smaller and relatively 

 narrower ; the elytra with the deep sutural stria shorter, and 

 each interstice with a row of very minute shallow punctures. 

 Found by Mr. H. Squire, in the spring and autumn, at 

 Whittlesea Mere and Horning. I secured several specimens 

 in Holme Fen, early in May last.
