British Species of Lathridius. 175 



transversus, Marsh. {Cor tic aria), 

 sculptilis, Gyll. 



6. testaceus, Waterh. 



, Stephens (not of Collection). 



Represented by immature specimens of Z. minutus in Stephens' 

 Collection. L. testaceus is readily distinguished by its short and 

 anteriorly much dilated thorax. 



7. carinatus, Gyll. 

 , Mannerh. 



The first British specimens of this insect which came under my 

 notice were in Mr. Wollaston's Collection. Unfortunately at this 

 moment I am unable to furnish their habitat ; I have latterly taken 

 several specimens in the corridor of the Crystal Palace. 



8. riificoUis, Marsh. (Corticaria). 



, Steph. lUustr., and Coll. 



, Curtis. 



-, (Marsh.) of Kirby's Collection. 



Liliputamts, Villa. 



■ , Mannerh. 



coUaris, Mannerh.? 

 Mannerheim unites the Corticaria riificollis of Marsham with 

 the Latridius constrictus of Gyllenhal — a very different insect, and 

 one to which the name " riificollis!' could never have been applied, 

 since it is uniform testaceous in colour. Judging from Manner- 

 heim's descriptions, I am inclined to refer both the L. Liliputanus 

 and the L. collaris of that author to the present species ; the dif- 

 ferences pointed out between the two insects being so slight that it 

 appeared to me I could refer some of my specimens of C. rvfcolUs 

 to the one, and some to the other description, and yet I fully be- 

 lieve my specimens (at least) to be all of the same species. 



9. elongatus, Curtis. 



, Steph. 



, Mannerh. 



In Mr. Stephens' Collection this species is represented by three 

 specimens of the true L, elongatus of Curtis, and one specimen of 

 L. filiformis, Gyll. 



10. JiUformis, Gyll. 



, Mannerh.
