Scolytidse /rom Ceylon. 327 



P. latifinis before me. Nevertheless, even with the assistance 

 of types, the females of the two species must remain very 

 difficult to distinguish. 



Platypus uncinatusj sp. n. 



Linearis, testaceus, capite et elytrorum apice fusco-piceis, his ante 

 medium pallidis, tcnuissime lineato-punctatis, prothorace lati- 

 tudine sesquilongiore sat subtiliter irregulariter punctulato ; femo- 

 ribus anticis subtus fortiter augulatis et ad apicem lobatis. 



cJ . Fronte subopaca, fortiter sparse punctata, striga brevi mediaua 

 impressa ; prothoracis sulco tenui, marginibus anterius punc- 

 tatis ; elytris prteter suturam stria singula notatis, interstitiis 

 planis, impunctatis, 3", 5" ad basin elevatis conjunctis, punc- 

 tatis ; ante apicem valde constrictis, impressione postica lunata, 

 nitida, utrinque impressa, ambitu superne transverse ad angulos 

 sutnrales baud rotundato, extus ad angulos postremos acute pro- 

 ductos subsiuuato, emarginatione interna sat profunda, lateribus 

 et basi singulatim leviter curvatis, illis versus apicem subconver- 

 gentibus. 



Long. 3-5 mm. 



2 . Fronte minus opaca, striga media variabili ; prothoracis sulco ' 

 congerie punctorum angusta, oblonga, circumdato ; elytris sub- 

 pallidioribus, versus apicem subangustatis, stria suturali tenuiore, 

 interstitio 3° ad basin gramdato, depressione postica lunata, sub- 

 nitida, sparse granulata, siipra subcallosa, margine inferiore late 

 arcuato, in singulo elytro quam suturali longiore. 



Long, 3-7 mm.

A very distinct little species. The male is allied to P. forfi- 

 cula, Chap., but is less robust, shorter, and much darker at 

 the apex of the elytra ; the posterior impression is deeper, 

 being about as long when measured along the suture as the 

 length of the emargination below ; this has the sides — that is, 

 the inner margin of the apical processes — and the base (the 

 lower apical border of the elytra) separately curved, the 

 former being slightly convergent and unarmed. From 

 P. hamatus, Blandf., and P. calamus, Blandf., it is at once 

 separated by the fact that the upper margin of the posterior 

 declivity is transverse and angulate, instead of being broadly 

 and obliquely rounded off at the suture. The female is 

 separable from those of the Platypi cupulati except P. pallidus, 

 Chap., by the narrow, oblong, cribriform patch on the pro- 

 thorax. From that species it differs in colour, in its greater 

 length and tenuity, in the frontal striga, the extremely weak
