13EMBIDIIDyE, TACHYPUS. 27 



Sp. 3. acutus. Nigro-osneus, nitidissimus, elytris subattenuatis acutis, tibiis 



pallidis. (Long. corp. 1 j lin.) 

 Ca. acutus. Mar sham. — T a. acutus. Steph. Catal. p. 41. No. 400. 



Entirely of a brilliant glossy bronzed-black, shining, as if varnished : the elytra 

 rather attenuated and pointed, punctate-striated, the striae not reaching to the 

 apex : legs pitchy-brass ; the tibiae pale testaceous : antennae fuscous, with the 

 base reddish. 



I strongly suspect that this supposed species is merely an imma- 

 ture state of the preceding. I have the original pair from Mr. Mar- 

 sham's cabinet, and one that I captured myself near London. 



Sp. 4. chalceus. Supra virescenie-ceneus, antennis pedihiisque piceis, elytris sub- 



tiliter punctata- striatis. (Long. corp. 2 lin.) 

 Ta. chalceus mihi. — Steph. Catal. p. 41. No. 402. 



Similar to the foregoing, but the antennae and legs differently coloured, the 

 elytra without impressed spots, &c. Bright brassy, shining : head with two 

 rather shallow parallel frontal sulci : thorax slightly convex, with a faint dorsal 

 line, the base with an impressed striola on each side: elytra bright glossy 

 brass, finely striated, the striae punctate, and not reaching to the apex : legs 

 pitchy : tibiae and tarsi sometimes rather paler : antennae pitchy, with the base 

 palest. 



The upper surface is sometimes greenish or bluish. 



A few specimens caught by myself near London, which appear 

 dissimilar to any of the preceding, being considerably larger, and 

 differing in other points as above described. 



Sp. 5. orichalcicus. Supra ceneus, antennarum Jemorumque basi tibiisque tes- 

 taceis, elytris subtiliter punctato-striatis, punctis duobus impressis. (Long, 

 corp. 2 lin.) 



El. orichalcicus. Illiger? — Ta. orichalcicus. Steph. Catal. p. 41. No. 401. 



Rather larger than the foregoing ; of a shining greenish-brass : head rather cu- 

 preous, with two parallel frontal sulci : thorax virescent, with a faint dorsal 

 line, and a very deep fovea on each side at the base : elytra bright coppery or 

 greenish brass, with two obsolete impressed dots ; faintly punctate-striated, the 

 striae not reaching to the apex, which is very smooth : body pitchy-brass be- 

 neath: legs pitchy-testaceous ; femora sometimes pitchy: antennae with the 

 base testaceous ; the apex dusky. 



I am not certain whether this is referable to the Eiaphrus orichalcicus of Illiger ; 

 it decidedly is not of Duftschmid ; though it accords with Panzer's figure, 

 which professes to be a representation of Illiger's insect : but not having this 

 last author's work, I cannot determine the point : it is very closely allied to 

 the two foregoing. 



Taken in the neighbourhood of London, and near Swansea.
