Mr. T. V. Wollaston on Additions to Madeiran Colcoptera. 341 



who has kindly presented it to the collection of the British 

 Museum. 



In my paper on "Additions to the Madeiran Coleoptera^^ 

 published in the August number of the 'Ann. of Nat. Hist.' 

 for last year^ I stated that the species detected in the grouj) up 

 to that date amounted to 646. I have therefore merely to re- 

 mark that the twelve here enumerated (four of which were first 

 detected by Mr. Bewieke, four by Mr. Anderson, two by Senlior 

 Moniz, one by Dr. Wolff, and one by myself) will raise the 

 number to 658. 



The few following notes may be conveniently inserted here : — 



1. Ptinella ajjtera (Ann. Nat. Hist. ser. 3. viii. 101). — The 

 little insect (detected in Madeira by Mr. Bewieke) which I cited 

 in my last year's paper of "Additions/^ under the name of 

 '^Ptinella afitera, Guerin/' appears to be the ratisbonensis, Gillm., 

 and not the aptera. The mistake arose through the Rev. A. 

 Matthews (who identified the species for me, whilst correcting 

 the nomenclature of the British Trichopteri/gidce) having had a 

 wrong type communicated from Paris. It appears to him, how- 

 ever (and, I may add, to me also) to be coincident specifically 

 with the English examples with which he originally compared 

 it, — the only diflference being that those examples are referable, 

 as he believes, to the P. r-atisbonensis, instead of to the aptera. 

 Its synonymy, therefore, will stand thus : — 



Trichopteryx ratishonensis, Gillm., Sturm's Deutschl. Fauna, xvii. (1845). 

 Ptinella ratishonensis, Matthews, Zoologist, 8058 (1862). 



2. Saprinus metallicus (Ins. Mad. 217). — I find that this in- 

 sect, which I have taken abundantly from beneath rejectamenta 

 on the sea-beach of Porto Santo, is not the metallicus of Herbst, 

 as I had imagined. From specimens which I sent to DeMarseul 

 for comparison, four years ago, and which have but lately been 

 returned, the species appears to be referable to the apricarius of 

 Erichson — an insect which is recorded from Spain, Corsica, 

 Sicily, Algeria, and Egypt. Its synonymy will consequently 

 stand thus : — 



Saprinus apricarius, Erichs., in Jahrb. 194 (18.34). 



, De Mars., Mon. des Hist. 725. 158 (1855). 



metallicus, Woll. [ncc Ilerbst], Ins. Mad. 21/ (1854). 



, Id., Cat. Mad. Col. 75 (1857). 



3. Enneadesmus harbatus (Ann. Nat. Hist. 3 ser. v. 359). — This 

 must be quoted as the XylopertJia barbuta, since it appears that 

 the XyloperthcE have, after all, but nine joints to their antenna), 

 and not ten as has usually been supposed. Consequently Mul-
