dedly remote from the anterior haunches; and the prosternal 
process is in correlation visible between the moderately ex- 
serted coxee. The anterior part of the prosternum, how- 
ever, 1S concave, showing an approach to the structure 
distinctive of the true Amphionychides ; and the lateral carina 
of the elytra is more or less clearly indicated. These typical 
species are connected by insensible gradations with others 
which have the same form of elytra and antenne, but the 
head much more strongly retracted, and well-developed 
elytral carine. ‘There are therefore no constant characters 
separating the two groups. 
EKulachnesia cobaltina. 
Elongata, postice modice attenuata, nigra, pube vel squamulis tenui- 
bus pallide viridi-ceruleis tecta, vertice vittis tribus, genis vitta 
utrinque lata (per thoracem continuata), thorace plaga dorsali 
antennisque nigris; genis (infra vittam nigram) prosternoquo 
utrinque vitta alba, in elytrorum basi aurantiaco-fulva, postice 
oblique ducta; capite valde exserto, vertice prolongato; elytris ante 
apicem curvatim angustatis, apice sinuato-truncatis et bidentatis, 
dorso punctulatis, costulis duabus carinaque laterali haud elevatis ; 
antennis utroque sexu corpore multo longioribus, filiformibus, 
robustis, infra usque ad apicem breyiter ciliatis.

Much resembling EZ. sapphira in colours, but differig in 
many points of structure: the head is much more elongated 
and voluminous; the elytra taper in a gradual curve to the apex 
instead of rectilinearly ; and the raised dorsal lines and carinee 
are only feebly indicated by the limiting punctures; lastly, 
the antenney have beneath a much shorter and less dense 
fringe of hairs. ‘The male example before me has the elytra 
almost entirely fulvous, probably owing to the abrasion of 
the fine blue scales.

Longissima, postice gradatim valde attenuata, nigra, subtus aureo- 
pubescens, capite thoraceque vitta lata laterali flava, elytris di- 
midio basali testaceo-flavo, dimidio apicali violaceo-nigro polito, 
sutura flavo- pubescente, antennis, pedibus et metasterni episterno 
fulvis ; capite longe exserto, vertice convexo ; thorace dorso nitido, 
convexo; elytris apice sinuatim truncatis, angulis productis, versus 
basin lineatim punctatis, apice levibus, carina laterali versus basin 
tantum elevata; antennis infra longe subdense ciliatis, articulo
