THE PSEUDOTRIMERA. 237 



volume, assuming in some species an irregular and 

 toothed appearance. The palpi are nearly equal in 

 balk to the antennae, the apical joint being strongly 

 hatchet-shaped and elongate. The elytra are always 

 more or less distinctly punctured in this genus, which, 

 with Bryaxis, is apterous. 



In Tychus, the fifth joint of the antennae is much en- 

 larged in the male. 



The species of Trichonyx are of considerable rarity, 

 and of (comparatively) large size ; they are light testa- 

 ceous in colour, of more elongate shape, and with the 

 antennae widely distant at the base instead of approxi- 

 mated, as in the preceding. They have been taken 

 under bark, among black ants in a tree, with yellow 

 ants under stones, and (in greater quantity) from moss. 



The Euplecti resemble Trichonyx in miniature, having 

 the antennae distant at the base, but they are more linear 

 and less convex, and occur in rotten wood, refuse heaps, 

 cut grass, etc., being, moreover, often taken on the wing. 



Three species, E. nanus (Plate XVI, Fig. 5), signatus, 

 and Karstenii, are not uncommonly found together in 

 decaying vegetable matter \ and the collector, who has 

 the means of doing so, should not fail to keep a heap of 

 dead leaves, compost, twigs, and cut grass in his garden, 

 as it will be found a constant trap for these and many 

 other species. 



Of the Clavigerides we possess one genus and species, 

 Claviger foveolatus (Plate XVI, Fig. 6), found in chalky 

 districts on the south coast and Surrey hills, associated 

 with small yellow ants, whose nests are formed under 

 large stones. It is very small, entirely yellow, shining, 

 eyeless, wingless, sluggish, with short stiff antennae, and 

 a deep depression in the middle of the abdomen.
