the " indication " of species as siiificient to validate a new 

 ijeneiic name, but the fact that this would permit any 

 cataloguer to introduce genera upon fantastic grounds 

 which, as in the present case, may not even pretend to be 

 morphological, seems to preclude the possibility of its ever 

 being generally adopted. 



Gerstaecker pointed out more than half a century ago 

 that (as would be expected) the African species of Steno- 

 tarsus are, in certain respects, more nearly related to the 

 Oriental s])ecies than to the American, and Gorham, in 

 describing the Japanese iS'. internexus, has noticed that it 

 forms the connecting hnk between the New World and 

 Old World forms. The genus is in fact a worldwide one, 

 passing with scarcely perceptible change of form from 

 Tropical Asia through Japan to North and Tropical 

 America, hke the Mongohan race of men, and through the 

 Eastern Tropics to Australia and Madagascar (S. inlernextis, 

 just mentioned, has an obvious relationsliip to the N. 

 American >S'. Jiispidus). 



S. guineensis Gerst., ranges from Sierra Leone to Uganda, 

 and S. aequatus Gorh., is a synonym for it. Gorham notes 

 that his type is much less pubescent than S. guineevisis. 

 This is true, the clothing having been rubbed of^ so that 

 scarcely a trace remains. S. momhonensis Weise, is 

 exceedingly similar, but the raised margin of the thorax 

 is narrower and the footstalk of the antenna only pale 

 at the base. It is connnon in Nyasaland and Gazaland. 



Stenotarsus ursinus and S. leoninus have been described 

 as unicolorous species, but examples of both occur in which 

 the elytra are marked with black spots in the same position 

 as in S. pantJierinus Gorh., the basal one, however, more 

 broadly adjacent to the anterior margin. In S. ursinus 

 the spotted form seems peculiar to North Borneo, while 

 Sarawak specimens never show more than a slight indica- 

 tion of spots. 



Gorham appears to have been wrong in attributing 

 Central American specimens to S. daviger Gerst., the form 

 of the antennal club in these agreeing rather with that of 

 S. validicornis. The specimen from St. Catherina referred 

 to by Gerstaecker as belonging to *S. daviger was in Gorham's 

 collection (now in the British Museum), but this specimen 

 does not agree with the description and must have been 

 too hastily examined by Gerstaecker, I believe it to be 

 a rather large specimen of S. yninutus.
