194 Mr. Walter F. H. Blandford's 



One example. This species differs so much from any 

 described Platypus as to be referable to no existing 

 division of the genus. Its nearest affinities seem to be 

 with the Plat I/pi Chvyuri, or perhaps the P. truncati, of 

 which not much is known. The abdomen is depressed 

 and ascends somewhat from the base to the apex ; but 

 the species does not appear to possess any relationship 

 with Crossotarsus, its maxillary structure being that of 

 a normal Platypus. Its position in the genus will be 

 much clearer when the opposite sex is known. 



Platypus hiuncus, sp. n. 



Linearis ; fronte bilineato-punctata et striga media impressa ; 

 prothorace eloiigato ; elytris lineato-punctatis. Long. 2-8 mm. 



Mas. Fusco-testaceus ; elytris posterius inf uscatis, ante 

 apicem constrictis, baud declivibus, depressione postica lunata^ 

 angulis productis, emarginatione longiore quam latiore, baud 

 dentata, ambitu superiore ad suturam transverse. 



Fem. Pallide testacea ; protborace plaga cribriformi angusta, 

 elongata, circa sulcum munito : elytris postice infuscatis, depres- 

 sione apicali lunata, margine suturali quam margine inferiore 

 breviore. 



Linear, tbe front nearly flat, more sbining in the male than the 

 female, with a short impressed median striga situate between two 

 longitudinal rows of punctures; vertex dull, without a shining 

 space, with a few deep punctures. Prothorax a half longer than 

 broad, the lateral emargination well-marked. Elytra about twice 

 as long as the prothorax, finely lineato-punctate, the interstices 

 scarcely visibly punctured. 



Male. Testaceous-brown, the elytra infuscate posteriorly. 

 Prothoracic sulcus rather long, with a group of 3 to 5 large 

 punctures on each side of its anterior extremity, remainder of 

 surface with irregularly mixed large and small punctures, absent 

 round the hind part of the sulcus, apex and base narrowly stri- 

 gillate. Elytra constricted before the terminal impression, the 

 inner rows of punctures stronger, the 2nd, 4th, 6th, interstices 

 impressed at the base and furnished with one or two granules ; 

 apical impression vertical, irregularly ovate, eraarginate below to 

 the middle, the emargination widening above and deeper than 

 broad, the fundus biconcave, with prominent margins, transverse 

 above at the suture, the apical processes produced downwards and 

 backwards, closely approximate at the tip, their outer margin sub- 

 angulate.
