Hah. Ghenada : St. George's, Mount Gay, and Vendome Estates, 

 leeward side. Grenadines : Becquia and Mustique Islands. 



This insect is longer than E. nigrocceruleus, and quite black 

 above. The legs seem darker than in the species I refer to this 

 name from Guatemala, but otherwise the West-Indian insect is 

 very similar. 



Eb^us minimus ? 



Anthocomus minitmis, Erichs. Ent. p. 113? 



Ebceus minimics, Gorh. Biol. C.-Am., Col. iii. pt. 2, p. 121 ? 



Hab. Grenada: Mount Gay and Vendome Estates, leeward 

 side ; Balthazar, windward side (H. H. Smith). 



The very minute size (about '75 of a millimetre), black or blue- 

 black colour, and the elj'-tra widened behind (as in E. nigroccmndeus) 

 distinguish this insect. It will be observed that the West-Indian 

 insect has dark legs, whereas the Guatemala specimens had yellow 

 legs. But there is not evidence enough to separate them.

 Ptinus, Linnaeus, Syst. Nat. i. pt. 2, p. 565. 



Ptinus tesellatus, sp. n. (Plate XXVII. fig. 8.) 



(S . Ohlongus, brunneus, dense suhrugose punctatus ; antennis 



hrevihna, artiadis secundo ad decimum suhcequaUbus, obconicis 



vix elonjatis, apicali parum elongato ; 2^^'othorace hirtuli, 



postice trnnsuerse impresso parum coustricto ; eh/tris griseo hir- 



tulis et pubefiavo tessellatis, punctato-striatis. Long. 2-5 millim. 



Hab. Grenadines: Mustique Island {H. H. Smith). 



This Ptinus is not like any with which I am acquainted. The 



antennae are short and with short joints more like those of Mptris 



crenatus : the thorax is constricted but not deeply, the widest part 



is in front of the constriction ; the prosteriial portion is very short, 



so that the head in repose must be reflexed ; it is almost detached 



in the two specimens before me and could hardly be extended 



without being so. The eyes are prominent and rather coarse. 



The elytra have the sides parallel. The punctures are numerous 



in the striae.
