also agree in the prominent eyes, in form, and in colours. The short 
seutellar stria is very variable ; but all the species have a single large 
puncture on the disc a little behind the middle. The prosternum has 
a slight raised rim at the apex, and is destitute of hairs. The middle 
ventral segments have, very generally, a transverse groove, visible 
chiefly at the sides. The three basal joints of the anterior tarsi of 
the ¢ are moderately dilated, triangular, with the angles rounded, and 
furnished beneath with two divergent rows of pectinated sguame, in 
some cases much elongated. 
Two species of the genus only have been hitherto described, 
differing from any of the following. All are found in Tropical America, 
under rotten, dead leaves, in dry situations in the forest, and run with 
great swiftness. 
ABARIS ROBUSTA, n. sp.—Oblongo-ovata, latiuscula, laete ceneo-cuprea, 
nitida, partibus oris, antennis, pedibus et ventro picers ; capite thorace dimidio 
angustiort ; thorace transverse quadrato, lateribus preesertim prope angulos 
anticos rotundatis, bast utringue bifoveolato et prope angulum punctato ; 
elytris fortiter striatis, striis exterioribus paulo profundioribus, interstitws 
subequalibus, stria abbreviata basalt curta inter strias mam et Q4am ; nectore 
nigro, interdum corpore infra toto rufo-piceo ; ventro transversim sulcato.

A large, robust species, found. generally throughout the Amazons, 
but not common. The general colour above is a glossy, eneous-coppery, 
the head and thorax and sides of elytra being often somewhat greener. 
The short basal stria does not approach either the 1st or 2nd stria. All 
the strie are sharply marked, in some places almost sulcate, and the 
lateral insterstices are not much narrower than the inner ones. The 
antenne are short, much thickened, and sub-moniliform towards the 
tips, the third joint not much longer than the 4th. The 4th—6th 
ventral segments have a sharp transverse groove near their anterior 
border, and not reaching the lateral margin. 
ABARIS PICIPES, n. sp.—Gracilior, oblonga, nigro-cenea, splendida, elytris 
jeupreis, antennis pedibusque piceo-rusis, oris partibus rufis, abdomine apice 
‘rufescentt ; capite thorace paulo angustiort ; thorace transverse quadrato, 
lateribus antice rotundatis, basi utringue bifoveolato et sparsissime grosse 
punctato ; elytris fortiter striatis, interstituis dorsalibus paulo latioribus et 
planioribus ; ventro haud sulcato.

Very similar in sculpture to A. robusta, but smaller, narrower, and 
more parallel, the head especially proportionally much larger, being
