128 ADErnAGA. [Trechns. 



large fovea on each side near angles ; elytra oblong ovate, much broader 

 than thorax, slightly dilated behind middle, with four strise next suture 

 distinct, the rest more or less obsolete, third stria with two incon- 

 spicuous pores ; legs testaceous. L. 3| mm. 



Sandy places on the coast and inland ; common and widely distributed throughout 

 the kingdom. 



V. nltusus, Er. This variety, which has by many authors been 

 considered a separate species, differs from the type in the following 

 particulars : the thorax is more rounded at the sides, and has the pos- 

 terior angles blunter, so that they almost appear to be rounded ; the 

 elytra are shorter, more rounded at the sides, and rather more dilated 

 behind middle, with two striae next the suture plain instead of four; the 

 pores on the third stria are also more conspicuous ; the wings, more- 

 over, are more or less rudimentary instead of being fully developed as in 

 the type; this last point, however, as we have seen in the case of Qdathus 

 fuscus (supra, p. 81), is of not much weight specifically, and taking into 

 consideration intermediate forms, the other distinctions are so com- 

 paratively slight that they are hardly enough to found a species on. 



This variety is widely distributed over England, and is found in 

 much the same localities as the type, but is always much rarer ; it is 

 common in Scotland both in the Lowlands and Highlands, being 

 apparently the commoner in the latter districts. 



T. rivularis, Gyll. {inciJis, Daws.). Pitchy-black or brown, some- 

 times ferruginous, with a metallic reflection on the elytra ; antenna; 

 reddish testaceous, the second, third, and fourth joints brownish, lighter 

 at apex ; thorax transverse, with the sides rounded, very slightly co]\- 

 tracted behind, side margins plain especially behind, posterior angles 

 small, acute, somewhat projecting, disc rather convex, dorsal furrow 

 fine, basal fovese large ; elytra long oval, somewhat convex, with three 

 deep broad striae near suture, of which the first reaches nearly to apex 

 and is recurved, and the second and third are abbreviated ; a fourth 

 stria is more or less plainly indicated ; underside blackish or reddish 

 with the apex of the abdomen lighter ; legs reddish testaceous. L. 5 

 mm. 



Very rare ; has not occurred for many years, and is perliaps extinct ; Whittlesea 

 Mere, July 1847 (Dawson); Holme Fen, several specimens (Power): the latter 

 locality has been brought under cultivation, or at all events the portion in which the 

 specimens were taken. 



T. secalis, Payk. (Epaphius, Leach). Pitch-brown or ferruginous, 

 shining ; antennae testaceous ; thorax short, very convex, with sides 

 strongly rounded, contracted behind, posterior angles quite rounded ; 

 elytra oval, convex, Avith very coarsely punctured striae, becoming 

 olisolete towards sides, third stria with the two usual pores ; legs testa- 

 ceous. L. 3| mm. 



This very distinct species may be at once known by its short oval
