respects it approaches Tijphlodcs, but it would not be 

 proper to associate it at present in the same genus with 

 the eyeless T. italicus. 



1. Litliocharodes fuscipennis, n. sp. Rufo-testaceus, 

 nitidus, elytris fuscis, a]^icc sunimo pedibusque testaceis ; 

 capite prothoraceque subtiliter punctatis, hoc lined media 

 impunctata. Long, corp. 2j lin. 



Antenna? about as long as the head and half the thorax, 

 stout, thickened towards the extremity, reddish ; 3rd joint 

 shorter than 2nd ; 4 — 10 transverse, not differing in length, 

 but the 10th twice as broad as the 4th; 11th joint stout 

 and pointed. Head rather broader than the thorax, longer 

 than broad, a little narrowed to the front, the hind angles 

 rounded, the anteunal grooves very fine; it is of a shining- 

 reddish colour, convex above, rather finely and moderately 

 closely punctured ; the back, and a line along the middle, 

 smooth : on the imder surface it is sparingly and finely 

 punctured in front, impimctate behind. Thorax rather 

 narrower than the elytra, twice as long as broad, rather 

 dilated in front, the fi'ont angles very rounded ; it is of 

 a shining reddish-yellow colour, at the sides finely and 

 rather sparingly punctured, a broad line down the middle 

 smooth. ScuteUum with one or two indistinct punctures 

 on each side. Elytra not so long as the thorax, pitchy, 

 Avith the extremity yellow, very finely and sparingly punc- 

 tured. Hind body yellow ; the 6th segment much longer 

 than the others, and a little infuscate, extremely finely 

 and rather sparingly punctured. Legs yellow. 



Tapajos ; one specimen. 



Metoponcus. 



This generic name is ap])lied by Kraatz to designate 

 the species forming Family I, of Erichson's genus 

 Leptaciims. It at present covers only seven species found 

 in Eastern Europe, tropical Asia, and South America. 

 I refer three Amazonian species to the genus, one of 

 which, however, viz. M. holisoides, is very different in its 

 appearance from the others, and will almost undoubtedly 

 be ultimately considered a distinct genus ; but I have not 

 been able in my examination of the only individual I have 

 seen of the species to detect characters that would justify 

 me in making a new generic name at present for it.
