ELMIS. 135 
A single individual only has been obtained of this species: it resembles somewhat in 
sculpture the species of Hlsianus; but the maxillary palpi are slender, the metasternum 
is coarsely granulate, and the basal ventral segment has an impression on the middle, 
limited by an elevation that is most marked behind, and that thus has somewhat the 
appearance of an obscure tuberculiform elevation at the first suture. 
2. Elmis sculptipennis. 
Elongatus, angustulus, nigro-fuscus, opacus, antennis pedibusque rufis; prothorace utrinque linea elevata, ad 
basin juxta hanc lineam impresso, basique in medio sulcato; elytris fortiter seriatim punctatis, parum 
distincte granulatis, utrinque versus latus linea elevata a basi ad apicem ducta. 
Long. 1, lat. vix 4 lin. 
Hab. GuatEMALA, Rio Naranjo 450 feet (Champion). 
‘Thorax elongate, very gently rounded at the sides, and only very slightly narrowed 
near the hind angles; parallel with the side there is a raised line extending the whole 
length, and the surface at the base close to the inner side of this line is more deeply 
impressed ; at the base there is a central longitudinal channel extending forwards for 
about half the length of the thorax, where it meets a very obsolete transverse depression. 
Elytra with series of very coarse punctures, the inner of which become obsolete towards 
the apex, and with a fine, very definite elevated line, extending from the shoulder to 
the extremity. Metasternum very coarsely granulate; basal ventral segment very 
deeply impressed on the middle. 
Only a single, rather immature individual has been found. It seems rather closely 
allied to E. champion; but the smaller size and the existence of a central channel on 
the thorax readily distinguish it. 
3. Elmis heteroceros. (Tab. IV. fig. 13.) . 
Parum elongatus, convexus, nigro-fuscus, subopacus, antennis pedibusque rufis, illis apice fuscis; prothorace 
conyexo, elytris angustiore, inequali, dorso longitudinaliter late depresso, utrinque versus latus ad basin 
linea crassa elevata; elytris granulatis, substriatis, striis sat fortiter punctatis, versus latus utrinque 
lineis duabus elevatis, interstitioque secundo ad basin elevato.

Hab. Guatemata, San Joaquin in Vera Paz (Champion). 
Var. Elytris ad basin et ante apicem plaga magna testacea. 
Antennz rather short and distinctly thickened at the apex, the four apical joints 
subserrate beneath, the two basal joints differing from the following ones, being a good 
deal stouter; the first is quite slender at the point of insertion, curved, and distinctly 
longer than the second, this latter suboblong, rather longer than thick. Eyes very 
convex. Thorax a good deal narrowed towards the front, but scarcely narrowed at the 
base, the sides much raised ; parallel with each is a broad indefinite elevation, which 
does not reach the front margin; on the middle, in front of the scutellum, the surface 
is longitudinally slightly elevated ; and in front of this there is a deep broad depression ;
