The punctuation of the elytra is not dense, and there 

 are no serial punctures to be observed ; the mesosternal 

 lamina, though sharply elevated, extends but little 

 forwards in the anterior direction. The darker colour of 

 the upper surface and the smaller mesosternal lamina 

 make the species very easily distinguished from P. 

 uniformis. 



A single individual in very bad condition was found 

 at Sapporo. 



Philydrus ornaticeps. 



Minutus, ovalis, sat convexus, nitidus, niger, antennis, palpis, 

 tibiis, tarsis, thorace elytrisque testaceis, capite nigro, macula 

 utrinque testacea ; crebre punctatus ; mesosterni lamina parva. 

 Long. 2 — 2^ mm. 



This, one of the smallest species of the genus, is in 

 colour very similar to P. uniformis, as also in punctua- 

 tion, and, as in that species, no serial punctures are 

 present ; the mesosternal lamina, though sharp and 

 definite, is very small. 



Kioto, July 4th, 1881. Also found by Mr. Lewis in 

 1863 at Kiu Kiang, in China. 



Philydrus umhratus. 



Ovalis, sat convexus, niger, supra fusco-testaceus, prothorace 

 elytrisque versus latera dilutioribus, capite nigricante utrinque 

 flavo-maculato, antennanim basi, tibiis, tarsis palpisque testaceis, 

 his articulo ultimo extrorsum infuscato ; supra crebre sequaliter 

 punctate, elytrisque praeterea seriatim punctatis, seriebus punc- 

 torum posterius profundioribus. Long. 5^ mm. 



This species is well characterised by the distinct lines 

 of close punctures on the wing-cases, which become 

 deeper behind so as there to form evident striae ; besides 

 this the elytra are closely punctured, and on some of the 

 interstices there can be distinguished in addition a few 

 larger punctures ; the insect is very similar to P. 

 simulans, but is readily distinguished by the absence of 

 deep striae, and by the greater development of the ordi- 

 nary diffuse punctuation of the wing-cases, so that the 

 irregular larger punctures on some of the alternate 

 interstices are not very conspicuous as they are in P. 

 simulans. The mesosternal lamina is large. 



This appears to be one of the commoner species of
