Platynin.e ii 



As generally in this subfamily, the close pubescence of the fourth 

 antennal joint ends abruptly near but not at the base, defining a 

 glabrous basal section or node of the joint, which is usually con- 

 spicuous. The remarkable difference between this structure and 

 that seen in the small species of the genus Europhilus is so marked, 

 that there could not be the slightest doubt of the generic validity 

 of the latter. 



Angiistatus Dej., differs from all other species of Platynidius that 

 I have seen, in having only three dorsal punctures, instead of the 

 four otherwise characterizing the third group above defined. 

 The specimen here identified as angiistatus answers very well to 

 the description of Dejean in the number and position of the three 

 punctures, as well as in other characters, and it is probably typical 

 in every way. It is not so narrow or depressed a species as rhom- 

 biceps. 



Rhadine Lee. 



The rather numerous species of this genus differ so conspicuously 

 from any other type of the subfamily in general habitus, due to 

 their flat surfaces, very slender form of body, frequently subopaque 

 integuments and pallid coloration in many cases, as well as in the 

 more elongate third antennal joint, that I think there can be little 

 or no doubt that the generic status could not very well be denied 

 them. The basal angles of the more or less elongate prothorax are 

 right in nearly every species, sharp and even rather prominent at 

 times to notably blunt, the pronotal impression feeble and the 

 foveae shallow and smooth; the sides of the prothorax are finely 

 reflexed in most of the species. The antennae and legs are notably 

 long and slender. Hind wings are wanting, the sides of the elytra 

 more or less feebly and gradually rounding at base, the elevated 

 elytral basal margin obtusely angulate at the humeri, forming 

 the posterior margin of an anteriorly sloping omoplate, and the 

 met-episterna are not or but very little longer than wide. The 

 elytra have three to four or five minute dorsal punctures, all very 

 close to the third stria as a rule. The species have been previously 

 reviewed in this series (Mem. Col., IV, 1913, p. 162) and it is there- 

 fore only necessary to refer the five following to their proper places 

 in the table there given :
