TEICHOPTERTGID^. 



Ptinella Proteus, Matth. 



This species is identical with P. testacea, Hear. The latter name has the 

 priority, and must be inserted instead of the former. 



Ptinella pallida, Er. 



It is very probable that this insect, which is generally regarded as a variety of 

 P. aptera, Guer., will eventually prove to be a distinct species. 



Trichopteryx convexa, Matth. 



The name of this species must be altered to T. convexiuscula, Mots., which has 

 priority. 



Teichoptertx pratercula, Matth. 



Easily distinguished from other species by the enlarged and peculiarly curved 

 posterior angles of the thorax (resembling the bill of the puffin, Fratercula arctica), 

 and also by the superficial sculpture of the same part. In the British list it comes 

 just before T. grandicollis. Taken by Mr. Matthews near Gumley (Ent. Mo. Mag., 

 XV, 65) . 



Tbichopteetx cantiana, Matth. 



Differs from T. lata in its thorax being much less dilated at the sides, its shorter, 

 more robust, and entirely black antennse, its deep black colour, and very short pubes- 

 cence. Taken by Mr. and Mrs. Wollaston near Tonbridge, and by myself near 

 Eepton (Ent. Mo. Mag., viii, 153). 



Trichopteryx L^titia, Matth. 



Allied to T.fascicularis, Herb8t.,but differs from that species in its smaller and 

 more depressed thorax, shorter and pitchy-black antennae, and in its conspicuously 

 smaller size. Taken in Belgium, near Spa, by Miss L. Matthews, and described as a 

 new species in Ent. Mo. Mag., ix, 189. First recorded as British by myself, in Ent. 

 Mo. Mag., xvi, 160. Mr. Billups and several other collectors have taken the species, 

 which is probably common. 



Trichopteryx Championis, Matth. 



A very distinct species, distinguished by its narrow form and castaneous tint : 

 it must be placed between T.fascicularis and T. seminitens. Taken in Wicken Fen ; 

 given to Mr. Champion by Mr. Hai-ris, of Burton-on-Trent, who received them from 

 a man living in the Fen district (Ent. Mo. Mag., xv, 64). 



Trichopteryx seminitens, Matth. 



Allied to T.fascicularis, but distinguished by the greater convexity of its form, 

 the shining surface and remote sculpture of the thorax, and shorter piceous antennae ; 

 allied also to T. attenuata, from which it differs in its larger size, much greater con- 

 vexity, shorter antennae, and in the sculpture of the thorax (Ent. Mo. Mag., xiv, 36).
