in the middle which is slightly angular, the posterior part is slightly 

 more oblique than the anterior, and the very strongly recurved 

 margin seems more highly raised in the posterior part owing to the 

 great depression of the sides, the median part of the disk is smooth, 

 but the sides are broadly and deeply punctured, the base has also a 

 broad band of punctures, but the anterior part is only slightly punc- 

 tulate, and the posterior angles are not very sharp ; elytra oblong, 

 with the sutural angle sharp, deeply punctato-striate with the 

 intervals convex, the third has one anterior and one median punc- 

 ture ; the two basal joints of the anterior tarsi of the male are slightly 

 sulcate outwardly. 



This species is very closely allied to P. crenato-striatus ; the 

 general facies is the same, but all the joints of the antennae are 

 navescent, and the punctures in the striae are not so deep, nor are 

 the intervals quite so much raised. 



Length 10-1H mm. ; width 4-4A- mm.

PLATYNUS (ANCHOMENUS) EMEBITUS, n. sp. 



Black, very shiny, especially the elytra; palpi, the basal joint of 

 antennae, the legs and the extreme edge of the prothorax and of the 

 elytra navescent ; head impunctate ; prothorax shaped as in 

 P. inxuctiis and P. crenato-striatus, that is to say slightly narrower 

 laterally in the posterior than in the anterior part and with the 

 posterior angles not very sharp ; the sides and base are also broadly 

 punctured with the median part of the disk smooth, but these 

 punctures are somewhat more closely set ; the elytra are oblong 

 with the sutural angle moderately sharp, punctato-striate, and the 

 intervals quite plane, the third interval has one anterior and one 

 median puncture ; the two basal joints of the anterior tarsi of the 

 male are not sulcate laterally. 



This species is also very closely allied to P. crenato-striatus, from 

 which it is distinguished by the plane intervals of the elytra, and the 

 non-sulcate joints of the anterior tarsi in the male. 



Length 9^ mm. ; width 3f mm.

PLATYNUS (ANCHOMEXUS) IXSOLITUS. 



Black, very shiny ; palpi and antennae reddish, with the basal 

 joint redder, legs navescent; head impunctate; prothorax shaped as
