242 Eustace W. Ferguson : 



ridge, very long, parallel-sided, apices broadly rounded; slightly 

 •curved inwards. Dimensions: <? 20 x 8 mm. Hah. — Victoria] 

 Type in A. M. Lea's collection. 



Close to F. cultrata but distinguished by its longer forceps; there 

 are also differences in the elytral sculpture. In P. cultrata the 

 length of the forceps beyond the insertion of the laminae is 1.5 mm., 

 in P. Leai 2.5 mm. In the type the genitalia are partly extruded 

 and in c(jnsequence the laminae overlap, in another specimen the 

 genitalia are at rest and the apices of the forceps mei'ely touch. In 

 my table this species would fall beside P. Sloanei, but the absence 

 of clothing together with shape of the forceps, not twisted, will 

 separate it. 



Talaurinus. 



Through the kindness of Mr. K. G. Blair of the British Museum, 

 who, at my request, made an examination of Bohemann's types in 

 the Hope Collection, I am now able to clear up the question of the 

 identity of the species comprised in the semispifiosus-gvonp. The 

 species constituting that group are all very closely allied and also 

 very variable, so that it is difficult to find reliable features for 

 separating the species. It is quite possible that some of these 

 species, here regarded as distinct, are not really so; but I think it 

 iidvisable to attach names to the most distinctive types, although in 

 some cases there may be intermediate forms tending to link them 

 up. The puncturation of the external rostral ridges and of tlie 

 liead, I have found of some importance. The clothing is on the 

 whole fairly constant. The tuberculation, both of the prothorai 

 and elytra, though to a certain extent variable, can also be made 

 use of. 



Talauriniis Roei Bohem. This is not the species redescribed by 

 me, but is identical with T. funereus Pascoe. It differs from all 

 others of the group in the much more closely and rugosely punctate 

 head and external rostral ridges, the latter being distinctly con- 

 vergent posteriorly. The head and rostrum, as viewed in profile, 

 are not in the same plane above ; the prothorax is closely and firtely 

 granulate; the elytra have the tubercles more acute, and more 

 spinelike, than in any other of the group. Of this species I have 

 an extensive series taken by Mr. H. J. Carter at Gingin, Western 

 Australia, and it is not too much to say that no two specimens are 

 •alike. The chief variation is in the number of the elytral tul^ercles ; 

 the head and rostrum and the prothorax are constant in their 

 •sculpture.
