hopeless to identify with absolute certainty — at least in Australia. 

 Dejean's description consists of 18 words, followed by a com- 

 parison of its subject with F. harhara (a species occurring on the 

 eastern shores of the Mediterranean Sea) ; de Chaudoir (with 

 exceptional facilities for comparison of types) is doubtful as to 

 the insect it is founded on. 



Next comes Simodontus ceneipennis, Chaud., which is fairly 

 well described ; but a note at the end of the description says that 

 "it is perhaps the Feronia australis, Dej." 



In 1865 M. Motachonlsky described what is no doubt a Simo- 

 dontus under the name (Argutor ?) antipodicm. [I have not seen 

 the description.] 



In 1868 the Count de Castlenau described as Feronia inedita 

 an insect which is probably either a Simodontus or a Leptopodus 

 from the Pine Mountains of Queensland. De Chaudoir in liis 

 memoir on the Castelnau collection makes no reference to it, from 

 which it is to be inferred that the type has perished. But the 

 description is, I think, sufficient to enable its identification on a 

 specimen taken in the locality cited if such should turn up, when 

 a more scientific description may be furnished. 



At the same time the Count described as species of Harpalus 

 two insects {Fortnumi and hrunneus) which in his report on 

 Count Castelnau'sj collection de Chaudoir asserts to belong to 

 Simodontus.'^ 



Three years later Sir William Mackay, in the " Insects of 

 Gayndah," described as Argutor three species {foveipennis, nitidi- 

 pennis, and oodiformis) which de Chaudoir says are Simodontus ; 

 of these fuller descriptions are desirable pointing out their dis- 

 tinctions from others of the genus. 



* I accidentally overlooked this note of de Chaudoir when in the Trans. 

 Roy. Soc. S.A. x. p. 190, I expressed a doubt as to whether H. Fortnumi 

 appertained to the Har2)alidce, but suggested that if of the sub-family at 

 all it might be a form of H. Deyrollei. Mr. Masters also has evidently 

 committed the same oversight in placing the two in Harpalus, in his 

 " Catalogue of the described Cokoptera of Australia."
