has become of the type of that insect I do not know, but 

 without it association of the two foi^ms as sexes is im- 

 possib'e. If this conjecture be correct, the male offers 

 no vahd reason for the separation of the species from the 

 Crossotarsi suhdepressi, as conjectured by Chapuis. 



Platypus pihilippinensis, sp. n. 



Mas. Nigro-piceus, nitidus ; fronte plana, dense areolato- 

 punctata ; prothorace oblougo ; elytris versus apicem subangus- 

 tatis et in processus productis, fortiter punctato-striatis, interstitiis 

 planis, similibus ; processu utroque ab altero discrete, longo, acuto, 

 postice producto et inferue curvato, in margine superiore dente 

 acuto armato. Long. 6-3 mm. 



Male. Pitchy-black, shining, subglabrous. Front flat, rugose 

 with very close areolate punctures, finer towards the mouth, their 

 interspaces forming a raised reticulum ; vertex with strong sub- 

 strigose punctures, the median and lateral smooth spaces evident. 

 Prothorax a third longer than broad, the sulcus fine, not reaching 

 the base, the punctuation distinct, sparse, rather closer towards the 

 middle of the disc but absent along the middle line and the mar- 

 gins of the sulcus, strong and close in the hind-angles of the 

 emargination and basal border, but not the apical. Elytra with very 

 strongly punctured striae, similar at the base, the punctures deep and 

 subquadrate, isolated before the middle, then more or less confluent, 

 the apical portions of the strise sulcate and curved outwards ; inter- 

 .stices flat, shiuing, similar throughout, closely punctate at the base, 

 the alternate interstices alone with a series of microscopic points 

 throughout, their apical portions much narrowed and subcostate, the 

 1st sulcate and split, its outer half curved outwards, the 3rd alone 

 seriato-punctate ; apices narrowed, produced backwards and some- 

 what downwards into two long acute processes, separated from each 

 other by a space nearly as deep as broad and widened from the 

 fundus to the apex of the processes, their upper border formed by 

 the conjunction of the outer half of the 1st, and 2nd interstices, 

 armed about the middle with an acute tooth directed backwards 

 and inwards, and thence curved downwards, their lower border 

 continuous with the 8th interstice and sinuate at its junction with 

 the elytra, their inner face concave, continuous with the declivous 

 median terminal portion of the elytra, which is internal to the 

 everted half of the 1st interstice, longitudinally convex and rugose- 

 Underside and legs concolorous ; abdomen depressed, rugosely 

 punctured.
