Ptilium caledonicum, Sharp. 



Also allied to P. Spencei, but very distinct : its thorax is rather narrower than 

 the elytra, much broader than long, with the sides rounded in front and much nar- 

 rowed behind, without any channel. It is fusco-testaceous in colour. Taken by Dr. 

 Sharp and Dr. Buchanan White, under bark of a dead Scotch fir at Braemar. (Ent. 

 Mo. Mag., Tiii, 73.) 



Ptilium c^sum, Er. 



A fine distinct species, easily distinguished by its wide form, large head, and the 

 convergence towards the front of the lateral lines of the thorax : it is dark testaceous 

 in colour. Taken by Mr. Crotch in 1870, in the Cambridgeshire Fens. (Ent. Mo. 

 Mag., ix, 179). 



PlElflDIUM ATOMAEOIDES, Mots. 



Easily distinguished from Pt. evanescens, Marsh, {apicale, Er.), by the smaller 

 size of its head and thorax, and much longer and broader elytra. Taken by Mr. 

 Crotch, probably near Brandon, in Suffolk. (Ent. Mo. Mag., viii, 152.) 



Ptenidium Keaatzii, Matth. 



This very distinct ant's-nest species is probably commoner than is supposed, and 

 is very likely often confounded with Ft. formicetorum, Kr. It is, like that species, 

 reddish in colour, but much darker, and has its elytra strongly punctured with large 

 punctures, whereas the elytra of Ft. formicetorum are almost glabrous. Two speci- 

 mens only (taken by Mr. Foxcroft, in Scotland) were known when the species was 

 described (Ent. Mo. Mag., viii, 152). I now record it for the first time as English, 

 having taken several specimens from ant's-nest rubbish from Buddon Wood, 

 Leicestershire, where it is probably common. 



Ptenidium Wanhowiczii, Matth. 



This species has been considered too close to Ft. apicale to be separated : it is, 

 however, quite distinct, being much narrower, especially in the thorax, the four basal 

 foveee of which are distinct ; in Ft. apicale they are obsolete. 



Ptenidium turgidicm, Thorns. 



Of this very rare and very distinct species hardly any British specimens were 

 known : some time ago, I found an example among some of Mr. Wilkinson's Tri- 

 chopterygidcB, in the possession of Mr. Mason, and Mr. Matthews subsequently 

 detected several others. 



CLAMBIDiE. 



Glanibus punctulutn, G-yll. 



This species must be omitted, the specimens on which Mr. Crotch introduced 

 it being apparently small C. minutus. (Ent. Mo. Mag., ix, 8.)
