 eiiiarginatc, and iViiigod anteriorly, its ])al])i short, with the 

 last joint laro-e, obovate. .Maxillii3 with tlie lobes of equal 

 breadth; the i)ali)i moderate, with the last joint cylindrical 

 and obliqnely trnneate. Trothorax transverse, rounded, ere- 

 nate, and expanded at the sides, but not foliaceous, elevated 

 and compressed above, and projecting over the head at the 

 apex. Elytra elongate, parallel, narrower than the prothorax, 

 posteriorlv abruptly declivous, sides nearly vertical ; the epi- 

 pleurai indistinct. Legs short ; femora not thickened ; tibiai 

 compressed, the outer edges 5-6-toothed, the anterior crescent- 

 shaped, the intermediate arched externally. Prosternum ele- 

 vated, rounded, not produced behind. Mesosternum entire. 

 Metasternum moderately elongate. Intercoxal process nar- 

 rowly triangular. Body tuberculate ; prothorax and elytra 

 above in an even plane throughout. 



There are three genera of Boletophaginge with ten-jointed 

 antenna; one is North American {PhelUdius'^ ^ Leconte), an- 

 other [Ozolais^ Pasc.) is from Ega, on the Amazons, and the 

 abovet ; as might be expected from three such widely sepa- 

 rated localities, there is very little affinity between them. 

 There are several genera, some new, with eleven-jointed an- 

 tenna, which, as they do not belong to Australia, I propose to 

 consider in a future"^ article : one of them has been recently 

 published as a Diceroderes {D. elom/afus, Redtenbacher) , but 

 it is a true Boletophagin {Di/sauteSjMS.).

 the scutellum ; the latter oblong rounded, a little raised ; ely-
