NEW BRITISH SPECIES x\OTICED IN I860. 65 



also avoid the obstacles it met with in its path, as I have 

 often seen these insects do. But the mystery is now solved ; 

 the many species comprised in the blind section of this genus^ 

 the * sans yeux' of the ^ Faune Fran^aise,' in reality p^ossess 

 as perfect visual organs as fall to the lot of any existing 

 beetle— the only peculiarity of these organs being the fact 

 that they are concolorous with the other parts of the head, 

 and situated mainly on its lower surface, a small portion only 

 being visible from above."— i?ey. A. Matthews, Zool. 7064

12. Ptinella angustula, Gillm. (nee Janson in Ent. 

 Annual for 1860, No. 21) ; Rev. A. Matthews, Zool. 

 7064(1860). 

 Trichopteryx angustula, Gillm. in Sturm's Deutschl. 

 Fauna, Ins. xvii. m, 6, T. 5, f. 6 (1845). 

 Found by the Revs. A. and H. Matthews in the Midland 

 Counties, and by myself in Surrey. Like its congeners it is 

 to be sought for beneath the bark of dead trees. 



In reference to the insect exhibited by me at the Meeting 

 of the Entomological Society on the 4th of April, 1859, and 

 enumerated in last year's Annual under the name of Ptinella 

 angustula, Mr. Matthews states: "While staying in Paris 

 for a short time in February last, I had the opportunity, 

 through the kindness of MM. Allard and Fairmaire, of 

 examining some of the French collections ofTrichopterygidfe, 

 and discovered that the species first taken by Mr. Janson,' 

 and subsequently by my brother, the Rev. H. Matthews, and 

 myself, was not the true angustula of Gillraeister, but one 

 which has been lately found near Paris by MM. Reiche, 

 Fairmaire and others, and described by M. Fairmaire under 

 the name of denticollisr—Rev, A. Matthews, Zool. 7064
