Scolytidge /rom Ceylon. 323 



These tubercles are more conspicuous in a still larger 

 specimen (2-5 millim.) taken at Belgaum by Mr. H. E. 

 Andrewes. 



As EichhofF has described under the name X. dilatatus a 

 form from Mauritius which differs from the present species 

 by characters precisely similar, it would appear that the two 

 are merely varieties depending on the size of the individual. 



XyJehorus dentatus, sp. n. 



2 . Linearis, cylindrica, nitida, ferruginea vel picea, prothoracis 

 basi rufeseente, antennis pedibusque ferrugineis, parcissime 

 longius pilosa ; fronte subconvexa, rarius sat fortiter punctata, 

 spatio medio subelevata Isevi ; prothorace oblongo, lateribus sub- 

 parallelis, apice fortiter rotundato, dorso medio subnodoso, poste- 

 rius uitido frequenter subtiliter punctiilato, punctis in linea media 

 et versus margiuem basalem obsolescentibus ; elytris prothorace 

 sesquilongioribus, lateribus subparallelis posterius subangustatis, 

 apice medio baud profunde emarginato ; supra lineato-punctatis, 

 linea suturali subimpressa, interstitiis planis vix perspicue seriato- 

 punctatis, 1° tuberculis 2 aut 3 minutis notato, declivitate 

 excavate- retusa, obcordata, fundo subconcavo, nitido, Isevi, 

 ambitu utrinque bituberculato, tuberculis acutis. 

 Long. 3-3-3 mm. 



Hab. Ceylon, Dikoya, Bogawantalawa. Several examples. 



The hairs on the elytra are limited to a very few at the 

 apex ; the terminal excavation is not very oblique nor con- 

 cave, its margin is raised and thickened, and the lower acute 

 tubercle is situated somewhat within it. Between the upper 

 and lower tubercles are usually situated one or two smaller 

 denticles. The apical emargination is narrow and shallow, 

 and the angles which it forms with the posterior margin are 

 thickened, but not tuberculate. 



The species appears allied to X. fallax, Eichh., which 

 differs in possessing three spines on each side of the apical 

 excavation which gradually increase in size. 



Eccoptopterus sex-spinosus, Motsch. 



Hab. Ceylon, Kitugalle, Dikoya. Four examples. 



This insect appears to be widely distributed. It has been 

 found in Ceylon, Damma Island, Burma, Borneo, Celebes, 

 Batchian and New Guinea. Some specimens from the two 

 latter islands possess one or two smaller spines on the lateral 

 border of the elytral declivity. This is well-marked in a 

 specimen from Borneo, which has five spines on each elytron. 

 But these subsidiary denticles are not constant, nor even
