foveaB at the posterior angles of the thorax, and by having 

 ihe elytra much antenuated towards the apex; the antennas 

 also are almost entirely black. 



Its place in our lists is next after T.fac'icola, Allib. 



Taken by Rev. A. Matthews near Gumley. 



120. Trichopteryx Guerin-ii, AUibert, Rev. Zool. 



(1844), 52; Fairm.; Rev. A. Matthews, Zool. 7975 



(1862). 

 Intermediate in size (and position) between T. &ericans^ 

 Heer, and T. pyymcBa, Erichs. ; much depressed in shape, 

 with the elytra usually more or less red, sometimes wholly 



so. 



Taken by Mr. Matthews near Gumley ; also by Dr. 

 Power.

iii. 26, 3; Gillm.; (nee Wat. Cat.). 

 canaliculatum var. Mark. 



ccBsiimj Ent. Ann. 1860 ; Wat. Cat. (nee Erichson). 

 Mr. Matthews writes to me that the true Pt. ccBsum, 

 Erichs., has not yet occurred in England ; the specimens 

 bearing that name in our collections, and found by Mr. 

 Gregson in ants' nests sent from Scotland, belonging to this 

 species. 



Mr. Matthews also informs me that the specimens taken 

 by ]Mr. Waterhouse, and referred by the former in Zool. 

 7410 (1861) to this species, are certainly distinct, and 

 probably must be referred to P. discoideum, Gillm. 



122. Ptilium insigne, Matthews, Zool. 7410 (1861\ 



described ; Wat. Cat. 

 Distinguished by the deep and wide longitudinal channel
