jierhaps an autlior's conception of one of his own species 

 becomes mod.fied as time rolls on and he sends three totally 

 diftVient forms to represent it at three diftVrent stages of his 

 caieer in answer to nrgent i-cquests for examples of his 

 species ?

Three species wei e originally referred to this genus : — 

 (1) W. acurninata, l^lackw. ; (2) W. crisfala, Blackw. ; 

 (3) W. cuspidata, Blackw. 'i he generic name being spelt 

 as above, not Walckenaera. 



W. acvminatii was withdrawn under Af icrt//)hatites ^ subgenus 

 Arrecerus, by Simon in 1864 under the natne A. camelhius 

 (C. L. Koch), with which, S'C. Tliorell and Simon, it is 

 identical. 



The second, W. crisfata, was withdrawn by Walckenaer in 

 1841 under his genus Argus under the name A. btcornis, 

 which, sec. 'J horell and Simon, = W. crutata. And thus 

 If. cnspiddta is left in as the type. 



Note. — It m;.kes no difference that Argus is a nr'm. pra?occ., 

 and in case any species should be left in the group, I heic 

 propose the name Melargus in its place. Jf ail the species 

 originally under Argus have been previously removed toothir 

 geneiic names, then Meturgus becomes a synonym under 

 whatever generic name is connected with the last species left 

 in or otheiwise seKcted as type, because the name under 

 which the type of Argus has b» en removed is in reality a
