BOTHROSTERNUS.—EUPAGIOCERUS. 133 
except at the base of the inner strie, the punctures divided by well-marked transverse elevations ; 
interstices convex, rugose and multipunctate from base to middle, acutely carinate on the declivity, the 
third elevated towards the apex. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Eight examples. The species is allied to B. costatus, Chap., but is larger and more 
robust, the prothoracic punctures are stronger and less close, confluent and not strigose 
towards the sides, and the inner strie of the elytra are manifestly punctured at base. 
2. Bothrosternus bicaudatus, sp. n. (Tab. VI. fig. 4, apex of elytra.) 
Oblongo-ovalis, glaber, nitidus, ater, antennis tarsisque rufescentibus ; elytris utrinque ad apicem in lobum 
rotundatum crenatum productis, supra striatis, interstitiis post medium argute costatis et subtuberculatis. 
Long. 3 millim. 
Mas. Fronte inter oculos carinata; rostro plaga fulvo-villosa ornato. 
Allied to B. sculpturatus, but distinguished from that and all other described species by the prolongation of 
the apices of the elytra into two short lobes, of which the outer borders are the longer, rounded and 
crenate, the inner borders forming the sides of a common subcircular emargination. Front (¢) with a 
transverse interocular carina, rostrum clothed with dense fulvous pubescence ; front and rostrum ( @ ) flat, 
thinly pubescent. Prothorax rather abruptly narrowed at the middle, very finely and closely punctured, 
with a fine reticular ground-work, denser towards the apex, which is dull and sericeous. Second ventral 
segment prominent, the last three slightly flexed as in Scolytus, the last ( 3) impressed. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three examples. A curious and interesting form. 
EUPAGIOCERUS, gen. nov. 
Oculi sat magni, emarginati; rostrum latum. Clava antennarum suturis curvatis instructa. Prothorax 
lateraliter acute marginatus, supra dense strigosus. Elytra ad basin subtransversa, interstitiis haud 
carinatis. Tibi antice fortius spinose ; tarsi validi, articulo 3° emarginato. 
This genus is established for a single species which links Bothrosternus to Pagiocerus 
without falling quite appropriately into either genus. ‘The rostrum is much wider than 
in Pagiocerus; the eyes are tolerably large and emarginate. The funiculus is widened 
towards the apex ; the sutures of the club are curved and the joints imbricate, but it 
is elongate as in Bothrosternus and not so compact an oval as in Pagiocerus. The 
prothorax has a sharp side-margin and is sculptured as in Cnesinus. The basal 
border of the elytra is narrowly elevated and subtransverse, being neither produced 
over the base of the prothorax nor crenate; the interstices are not costate, and the 
third is not prominent behind as in Bothrosternus. The spines of the fore tibize are 
large ; the apical processes of the middle and hind pairs are small and bifid, the upper 
margin of the former has two small spines, that of the latter is unarmed. 
1. Eupagiocerus dentipes, sp.n. (Tab. VI. figg. 5; 5a, antenna.) 
Oblongus, subnitidus, subglaber, piceo-niger vel piceus, capite nigro; prothorace dense punctato-strigoso, 
elytris striatis, interstitiis subconvexis, tenuiter multipunctatis, in declivitate angustatis, seriatim tubercu- 
latis et brevissime setosis, declivitate ipsa subimpressa. 
Long. 3 millim.
