322 Mr. W. F. H. Blandford on 



evidently impressed elytral strife ; the anterior margin of the 

 prothorax is also a little more rounded. 

 These differences are hardly specific. 



Xylehorus semim'tens, sp. n. 



$ . Oblonga, cylindrica, joicea, breviter pilosa, autennis pedibusque 

 ferrugineo-testaceis ; fronte convexa, subglabra, opaca, subtiliter 

 sparsim punctulata, ore ciliato ; ooulis oblongis, profunde emar- 

 giuatis ; prothorace oblongo, lateribus subparallelis, apice fortiter 

 rotundato, iiugulis posticis obtusis ; dorso ante medium trans- 

 verse subelevato, anterius asperate, posterius subopaco, dense 

 alutaceo et hinc illine subtiliter punctidato : elytris prothorace 

 vix tertia parte longioribus, lateribus ad medium parallelis, inde 

 rotundatis, margine apieali singulo obliqua, subrecta, apice ideo 

 acuminato ; supra ante medium nitidis, lineato-punetatis, lineis 

 parum impressis, punctis minutis postice subdilatatis, interstitiis 

 planis confuse subtiliter punctatis ; declivitate ante medium inci- 

 piente, convexa, infra carinata, pruinoso-opaca, interstitiis 

 tuberculis parvis setiferis uniseriatim instructis ; tibiis extus 

 rotundatis, subtilissime serratis. 

 Long. 3 millim. 



Hah. Ceylon, Dikoya. Two specimens. 



This species differs from any known to me in which the 

 prothorax is subcylindrical by the acuminate elytra, the de- 

 clivity of -which is dull, with the interstices very finely and 

 equally tuberculate. 



Xylehorus perforans, Woll. 



Hah. Ceylon, Dikoya, Balangoda ; India, Madeira, &c. 



I have elsewhere identified the Ceylonese species, which 

 has been described by Walker under the name Bostrichus 

 testaceus and by Eichhoff as X. Kro.atzi^ with Wollaston's 

 Tomicus perforans. Possibly Anodius tuherculatus, Motsch., 

 is a synonym of the same species. 



Xylehorus parvulus, Eiclih. 



Hah. Ceylon, Kitugalle ; India, Belgaum (Andrewes) ; 

 Mauritius {Eichhoff). 



The single example taken by Mr. Lewis differs from 

 Eichhoff's description in being a little larger (2"3 millim.), 

 rather darker in colour, in having the apex of the thorax 

 somewhat transverse, in possessing no tubercle at the sutural 

 angle of the elytra, whereas it has additional very fine 

 tubercles on the first interstice before its declivous portion 

 and on the third and fourth interstices.
