BEMBIDIJD^. TACHYS. 5 



Sp. 1. scuteliaris. Subdepressus, niger, elytris pallidis versus suturam uirinque 



obsolete tristriatis. (Long. corp. l\ lin.) 

 Ta. scuteliaris mihi.—Steph. Catal. p. 36. No. 343. 



Somewhat depressed ; black : head smooth, with a deep impression on each side 

 in front between the eyes: thorax with the disc slightly convex; a strong 

 dorsal channel, and a slight fovea on each side at the base : elytra pale, with 

 the region of the scutellum dusky, and the hinder half somewhat suffused 

 with the same ; on each side of the suture three imperfect and obsolete 

 punctate striae, vanishing at the tip ; the exterior portion of the elytra smooth, 

 with a deep impression on the disc : legs very pale : antennae pale at the base, 

 slightly fuscescent towards the apex : labrum and mandibles pale fulvous, the 

 latter with the tip dusky. 



Two specimens of this species were taken on the sandy coasts 

 of Hants, by an active and industrious collector, Mr. D. Bydder, 

 some years since ; they are the only examples I have hitherto seen, 

 and greatly resemble the insects of the preceding genus upon a 

 transient inspection. 



Sp. 2. binotatus. Nigro-ceneus, elytris striatis puncto apicali, tibiis tarsisque 

 pallidis. (Long. corp. 1^ — 1^ lin.) 



Ta. binotatus mihi. — Steph. Catal p. 36. No. 344. 



Brassy or greenish-black ; slightly glossy : head with a deep longitudinal im- 

 pression on each side, between the eyes : thorax a little convex, obsoletely 

 wrinkled transversely, with a faint longitudinal channel, and a deep im- 

 pressed fovea on each side at the base : elytra slightly convex, striated, the 

 striae composed of punctate dots, and nearly obliterated on the outer edge of 

 the elytra, towards the apex of which is a round pale spot : femora pitchy- 

 black ; tibiae and tarsi pale fulvous : antennae fuscous, with the basal joint 

 rufescent. 



Not uncommon throughout the metropolitan district. " South- 

 end."— Rev. F. W. Hope. 



Sp. 3. vittatus. Nigro-wneus, elytris striatis, vittd apicali pedibusque pallidis, 



(Long. corp. lj — 1^ lin.) 

 Ta. vittatus mihi. — Sleph. Catal. p. 36. No. 345. 



Rather larger than the last ; deep, glossy, brassy-black ; head as in the last : 

 thorax smooth, or very obsoletely wrinkled transversely, with a faint longi- 

 tudinal channel, and a small impression on each side at the base: elytra 

 rather deeply punctate-striated, the striae obsolete at the apex ; the latter witli 

 an undefined pale streak, or sometimes entirely pale: legs entirely pale- 

 fulvous: antennae dusky, with the basal joints reddish. 



Common in damp banks, &c. near London. " In Copenhagen- 

 fields, near ponds." — Mr.. Ingpen.
