126 RHYNCHOPHORA. 
47, Epicerus tristis. 
Epicerus carinatus, var., Boh. in Schénh. Gen. Cure. vi. 2, p. 285°. 
Synthlibonotus tristis, Chevr. Bull. Soc. Ent. Fr. 1880, p. xl’. 
Niger; prothorace elongato, lateribus rotundatis, fortiter rugoso-punctato, dorso longitudinaliter depresso ; 
elytris seriatim fortiter punctatis. 
Long. 10-11 millim. 
Hab. Mexico, Jacale, Vera Cruz}? (Sallé). 
Rostrum canaliculate along the middle, with a small fovea at the summit of the 
channel, on each side a deep, moderately long impression; the surface somewhat closely 
punctate. Thorax elongate, rounded at the sides, with the greatest width in front of 
the middle; the surface rendered very uneven by coarse punctures, and also with a 
minute interstitial punctuation, somewhat shining, with a vague depression along the 
middle. Elytra elongate and narrow, black, but rendered somewhat dull by a thin 
adherent squamosity ; with regular series of rather large distant punctures, and on the 
declivous portion with a very scanty setosity. Legs elongate. Six specimens. 
There is not much difference between the sexes of this species, the female having the 
elytra only a little broader than the male, and the suture behind more prominent. I 
have examined a type from Chevvrolat’s collection communicated by Dr. Aurivillius. 
48. Epicerus concolor, sp. n. 
Niger, opacus, brevissime setosus ; prothorace fortiter profunde rugoso-punctato; elytris seriebus punctorum 
minus remotorum. 
Long. 93-10 millim. 
Hab. Mexico, Las Vigas (fége). 
This is one of the species that, though covered with scales, still appears quite black. 
It is closely allied to L. tristis, but is readily distinguished by the much smaller, more 
numerous punctures in the series of the elytra. The rostrum is deeply sulcate along 
the middle in the male, more broadly and less deeply so in the female; the lateral 
impressions are elongate and distinct; and there is a rather large fovea between the 
eyes. Thorax elongate, very coarsely and deeply punctate, a little flattened and 
impressed along the middle in the male, but scarcely at all so in the female. Elytra 
quite dull, furnished with very regular series of rather fine punctures, with a short 
minute serial setosity on the interstices. 
Five specimens have been obtained of this species. There is a good deal of difference 
between the sexes, the female being a much broader and more obese insect than the 
male and having the apical portion of the elytra more elongate and perpendicular.
