Scolytidae yrom Ceylon. 327 



P. lati'finis before nic. Nevertheless, even witli the assistance 

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

 difficult to distinguish. 



Platypus uncinatusj sp. n. 



Linearis, tcstaceus, capito ct clytronim apico fusco-piceis, his ante 

 medium j)allidis, tonui>sirae lineato-puiictatis, prothorace lati- 

 tudine sosijiiilongioresat su])tiliter irrcgulariter punctulato; ferao- 

 ribua anticis subtus fortiter auf^ulatis et ad apicem lobatis. 



cf . Fronte stibopaca, fortiter sparse j)unctata, strijja brevi mcdiana 

 imprcssa ; prothoracis sulco tenui, marpinibus anterius pnnc- 

 tatis ; elytris prieter suturara stria singula notatis, iuterstitiis 

 planis, irapunctatis, 3", 5" ad basin elevatis conjunctis, puuc-

 nitida, utrincpic im])ressa, ambitu superne transverse ad angulos 

 suturalcs baud rotiuidato, extus ad angulos postremos acute ])ro-

Long. 3-5 mm. 



2 • Fronte minus opaca, striga media variabili ; prothoracis sulco 

 congerio punctorum angusta, oblonga, circumdato ; elytris sub- 

 pallidioribus, versus apicem subangustatis, stria suturali tenuiore, 

 interstitio 3" ad basin granulato, depressiono postica lunata, sub- 

 nitida, sparse granulata, supra subcallosa, margine inferiore late 

 arcuate, in singulo elytro quam suturali longiore. 



Long. 37 mm. 



Hab. Ceylon, Dikoya, Bogawantalawa ; several examples. 

 India, Belgaum {Andreioes). 



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

 cula, Chap., but is less robust, shorter, and mucli 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 cmargination 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. hamatuff, Blandf., and P. calavixis, Bhindf., it is at once 

 separated by the fact that the upj)cr 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 cupiilati cxccy)t P. pallidusj 

 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
