but is very readily recognized by the very deep transverse impression extending across 
the middle of the thorax; the antenne are elongate and slender; the middle of the 
thorax is quite free from sculpture, and rather shining, possessing only a very fine 
pubescence. ‘The very coarse punctuation on the basal portion of the elytra is in 
remarkable contrast to the impunctate apical portion. The metasternum is impressed 
along the middle, and, like the middle of the basal ventral segment, is very finely 
coriaceous. 
6. Elmis ineequalis. 
Angustulus, niger ; antennis rufis, articulo ultimo rufo-fusco ; pedibus piceo-rufis, tarsis dilutioribus ; prothorace 
elongato, elytris angustiore, ineequali, lateribus subbisinuatis, utrinque versus latus linea subtili elevata ; 
elytris ad basin fere grosse punctatis, dimidio apicali fere impunctato, versus latus utrinque lineis duabus 
elevatis, quarum externa elongata.

Antenne rather elongate, red, the apical joint quite as long as the two preceding 
together, and rather darker in colour. Thorax longer than broad, scarcely narrowed 
to the front, the sides slightly bisinuate, the surface very uneven; parallel with each 
side is an elevated line, on the disk is a deep impression, and in front of the base on 
each side of the middle is a large rather indefinite oblique impression, and between the 
raised line and the side-margin there is towards the front a still more indefinite 
impression. .The scutellum is rather large, but is longer than broad. The elytra are 
rather elongate and narrow ; near the side of each is a strongly elevated line extending 
from the shoulder to near the extremity, and parallel with this, nearer the suture, a 
shorter line extending only about halfway to the apex; the basal portion bears some 
coarse deep punctures; but the apical half is nearly impunctate. Beneath the meta- 
sternum is uneven, owing to some large impressions. ‘The maxillary palpi are rather 
slender; the third joint is subquadrate, about half the length of the fourth joint. 
A large series, showing very little variation, has been obtained of this species. 
7. Elmis distortus. 
Elongatus, convexus, nigro-fuscus, antennis pedibusque elongatis, gracilibus ; prothorace angusto, elongato, 
valde inequali, ante medium subconstricto, utrinque linea elevata ; elytris ad basin punctis sat magnis, ad 
apicem fere impunctatis, externe lineis duabus elevatis, quarum interna postice abbreviata.

Antenne elongate and very slender, not at all thickened at the extremity. Thorax 
narrower than the elytra, very elongate, the sides very conspicuously crenulate, the 
surface very uneven, there being a large impression on the middle, and behind this, on 
each side, an obliquely curved impression, nearly joining its fellow at the middle; a tine 
elevated line runs on each side from base to apex and is sinuate about halfway.
