500 Mr. M. Jacoby on 



Head remotely but rather strongly punctured, the interstices 

 sjaaringly clothed with erect whitish hairs, antennas extending 

 slightly beyond the base of the elytra, fulvous, the apical joints 

 fuscous, strongly thickened, the fourth joint about tlie length 

 of the second one, the third more elongate ; thorax nearly twice as 

 broad as long, the sides strongly rounded, the anterior portion rather 

 strongly deflexed, the surface strongly but not very closely punctured 

 at the disc, the punctures more crowded at the sides, of round shape, 

 the interstices clothed with long white hairs, scutellum broad, 

 punctured ; elytra convex, parallel, much more finely punctured than 

 tlie thorax, the punctures more distinct at the basal portion than 

 posteriorly and arranged in closely approached irregular rows, the 

 shoulders acutely costiform ( 5 0? ^''^ interstices everywhere furnished 

 with long white hairs ; below and the femora ajneous, the tibite 

 towards the apex and the tarsi fulvous. 



Rah. Bahia (Frnhstorfer). 



Larger than S. airuginosus, Lef., the thorax less closely 

 punctured and the apex of the tibiae and tarsi fulvous. I 

 am uncertain as to the sex. 



EDUSINiE. 



In this and the following sections are placed all those 

 Eumolpidie which have postocular lobes, or in which the 

 anterior margin of the thoracic episternum is more or less 

 convex, in opposition 'to the previous genera in which the 

 same part is straight or concave ; there are, however, 

 many instances in which this character is obsolete, and the 

 student is in doubt to which of the two groups the insect 

 may be referred. These cases are, however, isolated, and 

 any other mode of division would be equally uncertain as 

 no character can be relied upon in the Phytophaga. It is 

 rather remarkable that this group is but feebly represented 

 in the New "World, most of the genera having their 

 metropolis in the Eastern portion of the globe. 



Argi a inucronata, sp. n. 



Greenish-peneous, antennae and legs fulvous, thorax closely 

 punctured and finely strigose, elytra strongly punctured, the 

 interstices transversely rugose at the sides, longitudinally costate at 

 the apex. 



Mas. The anterior tiliiee with a short spur at the apex, tlie tarsi 

 dilated.
