Rio Janeiro. Nearly allied to 7. xanthura, and, notwithstanding 
the difference in coloration, possibly only a variety. My two speci- 
mens differ greatly in the distinctness of the elytral striz, and I suspect 
this character is variable in the whole of the group. The cruciform 
mark of the elytra is of a reddish-piceous hue, and ill-defined from the 
pale tawny ground colour. 
TACHYTA LIVIDA, n. sp.—Elongata, angusta, depressa, livido-testacea, 
nitida, capite marginibusque elytrorum paulo obscurioribus ; antennis bre- 
vissimis, articulo basali flavo-testaceo, reliquis obscuris ; thorace breviter 
cordato, lateribus antice valde rotundatis, postice fortiter sinuatim angus- 
tatis, angulis posticis productis, rectis ; elytris elongatis, parallelis, stria 
suturali solum distincte impressa, disco punctis duobus setigeris, striola 
recurva lata haud profunde impressa. Long. lin. 4 exempl. 
Adelaide, S. Australia. From Mr. J. Odewahn. A curious species, 
distinguished by its elongate, narrow, parallel form. 
Ops. (1) The following species of Tachys are omitted or wrongly placed 
in Gemminger and Harold’s catalogue : 
Tachys monochrous, Schaum, Berl. Ent. Zeit. 1863, p. 90... Melbourne. 
» ornatus, Apetz, de Col. O. et A. Brehm eee &e., 
ci ee Be ... Upper Egypt. 
Bembidium ia ae Me : Harald Cat, 
Oxs. (2) Zachys eneopiceus, Bates, E. M. Mag., vol. vii. I should have 
mentioned, in the description, that this species has the closest 
possible resemblance to Pericompsus metallicus ; the absence of a 
sixth dorsal strive, which excludes it from Pericompsus, furnishing 
the sole definite distinction. 
Oorrerus (group Trechine) Macevyt, nu. sp.—O. elivinoide latior, 
multo minus convexus, fusco-cupreus, subnitidus, mandibulis, palpis basi et 
apice, antennis basi, pedibus, marginibusque elytrorum piceo-rufis ; capite 
levi, sulcis frontalibus latis, plicisque duabus utrinque prope oculum ; tho- 
race vix convexo, quadrato, postice sinuatim leviter angustato, angulis pos- 
ticis productis, acutis, basi utrinque bifoveolato et punctato ; elytris 
‘ellipticis, modice convexis, striis punctatis, leviter impressis, interstitio 3ie 
quadripunctato ; tibiis, presertim anticis, infuscatis.
