MB. r. p. PASOOE ON TUE CUIlCULIONIDiB. 175 



cuius 7-articulatu9, articulo primo crassiore, longiusculo, se- 

 cundo paulo breviore, cseteris trans versis ; clava magna, ovalis. 

 Oculi laterales, grosse granulati. Frotliorax oblongus, sub- 

 cylindricus, basi bisinuatus, margine inferiore antice fortiter 

 emarginato. Elytra protborace paulo latiora, elongata, paral- 

 Icla, basi producta, postico subito declivia; femora clavata, 

 posteriora apicem elyfcrorum superantes, pedunculata, in medio 

 fortiter clavata et proeessu triangulari denticulate munita; 

 tibi(s breves, arcuatse, compressa? ; tarsi normales ; coxcb antica) 

 parum sejunctae. Abdomen segmentis duobus basalibus valde 

 ampliatis. 



The type of this genus is very like some of the smaller Austra- 

 lian Orthorini, to which, in fact, it is closely allied, differing 

 principally in the character of the tibiae and of the posterior fe- 

 mora ; the latter are very remarkable, and can only be paralleled 

 among the Tachygoninae, a subfamily of the Aulacostethous ca- 

 tegory. From a slight difference in the rostrum I suspect my 

 two examples are male and female.

The diagnoses of this and the following species are drawn up 

 to contrast with the two described by Lacordaire. In this spe- 

 cies, which approximates to JD. hcilopoides, the elytra are gradually 

 narrowed to the apex, which is deeply and angularly emarginate, 

 with the outer augle on each side rather produced j the femora
