Descriptions of New Scolytidx. 211 



punctures. Scutellum obtuse triangular, shining. Elytra as wide 

 as the prothorax and less than a half longer, truncate at base, the 

 shoulders nearly rectangular, the sides subparallel to near the apex, 

 then strongly incurved ; surface pulvinate and convex from the 

 base, obliquely declivous and somewhat less convex behind the 

 middle, the basal half not deeply punctate-striate, the punctures 

 shallow and rather large, the sutural stria not impressed, interstices 

 flat, shining, subimpunctate, the sutural interstice with a few small 

 granules ; apical half opaque, less distinctly striate, the interstices 

 with a single series of rather remote small elevated points ; declivity 

 acutely carinate below, the carina not crenate. Underside and 

 legs testaceous. 



Hah. Borneo (Wallace). 



Allied to X, semlopacus, Eichh., but differentiated 

 from it and the following species by the distinct stria3 

 and subimpunctate interstices of the basal balf of the 

 elytra, 'i'lie prothorax is rather obtuse at the apex, and 

 thus approximates somewhat in shape to that of X. validus, 

 Eichh. One example. 



Xtjlehorus semujranosus, sp. n. 



Fem. Oblonga, subuitida, rufoferruginea, prothoracc ajque 

 longo quam lato, lateribus leniter, apice fortius rotundato, disco 

 obtuse transverse gibbo, post medium subtiliter punctato ; elytris 

 prothorace vix tertia parte longioribus, ante medium subtiliter 

 quasi confuse punctatis, post medium convexe declivibus, opacis, 

 granulatis et erecte seriato-pilosis. Long. 2*4 mm. 



Female. Oblong, slightly shining, ferrugiuous-red, rather 

 darker posteriorly. Front subconvex, subnitid, rather strongly 

 punctured, thinly hairy, the mouth fringed with pale hairs ; eyes 

 oval, emargiuate, tolerably large ; antenna3 pale testaceous. Pro- 

 thorax as long as broad, strongly rounded at the apex, the sides 

 very slightly curved and subparallel from the middle to the base, 

 hind-angles obtuse but not rounded, the base truncate ; surface 

 with a very slight median transverse elevation, scantily but 

 uniformly pubescent with fine hairs, in front convexly declivous, 

 with granular asperities, somewhat irregular and scattered towards 

 the apical margin, behind the middle cyliudrico-convex, subnitid, 

 finely but evidently punctured, the punctures stronger over the 

 middle portion, median smooth line absent. Scutellum triangular,
