of a genus were known to him (and as must often be the case 

 with others) those species are not truly representative of the 

 •whole genus. Foropterus I regard as typical of the whole sub- 

 famil}!-, having few characters that may be relied on generically, 

 the species variable in size and sexually variable, and having 

 affinities in the most unexpected directions. A number of species 

 have been referred to it which should be excluded. I do not 

 think that any species having the two basal abdominal segments 

 soldered together should be admitted, and on this account I 

 exclude pon-igi7ieus, Pasc.,* which seems to be much closer to 

 Paieticus ; neither should any species having the mesosternal 

 receptacle straight at its apex; satyrus, Va.HC., Jbveipennis, Pasc , 

 musculus, Pasc, ie^riczts, *Pasc., should perhaps also be excluded; 

 they are unknown to me except by description. I exclude ^e??i?<?-, 

 Pasc, for which a new genus is required; tumulosus, Pasc, is not 

 properly referable to Poroptei'us; it is closer to Petosiris, but a 

 new genus is required to receive it and several other species I 

 possess. Probably species standing in other genera (especially in 

 Acalles and Ci'yptorrltynchus) are referable to it. I refer Mormo- 

 sintes rubus to the genus, the linear tarsi on which Pascoe founded 

 Monaosintes not appearing to warrant generic separation. Pascoe 

 .states that " Ciirculio luridus, Fabr., placed in Acalles in the 

 Munich Catalogue, is a Poropterus." In Masters' Catalogue, 

 Cry ptorrliynchus fidiginosiis, Boisd.,is placed as a synonym of that 

 species, as also Acalles immansuetios, Bohem. If this synonymy 

 is correct, the species is certainly not a Poropterus, as in describ- 

 ing immansuetus Boheman says, '■^ feniorihus .... sublus 

 dente parvo, ubtuso, armatis " ; a character which would at once 

 exclude it. 



Members of the genus are to be found along the entire eastern 

 coastal districts of Australia; they are scarce in South Australia 



* In this species the two basal abdominal segments are not free, though 

 ■on a first glance they appear to be so ; on removing the scales, however, 

 then- true nature is to be seen.
