164 THE CANADIAN ENTOMOLOGIST. 



visibly incrassate throughout their length, pale ; body jjiceous-black, 



the legs slender, dark brown throughout. Michigan. ..Ifuronicus, Csy. 



Basal thoracic impressions very feeble ; body smaller and slender ; antennae 



thinner but more obviously incrassate from base to apex, black, the 



antennas and legs pale, the femora blackish. Florida (Indian 



River) sagax, Csy. 



The types as described above are males throughout, having padded 



femora, except de?isus, of which the only known representative is a 



female. The key to the interpretation of sexual identity here, assumed 



was fortunately given by the two specimens of Wickhatni before me, and 



it is regrettable that a greater number of individuals are not known in 



other species, in order to verify or modify the conclusions arrived at from 



this pair. The sexual differences certainly appear to have developed a 



most unusual form, since femoral modifications of the kind noted in the 



assumed females of Vanonus almost invariably pertain to the male. The 



types of congetier and Jiisciceps, following my original hypothesis, were 



the females of other species of the piceiis group, but, upon the theory that 



all the individuals with padded femora are males, they could be considered 

 in no other light than distinct species. 



The generic name Schizonotus (Col. Not., IV., 1892, p. 708) is 

 several times preoccupied, and I would therefore substitute Schizomicrus. 

 The genus Psendolesteva, Csy., (1. c, V.. p. 398) is also preoccupied, and I 

 would therefore substitute for it the name Faralesteva. 



A copy of the " Index Zoologicus," of Waterhouse and Sharp, just 

 received, forms a very uset'ul addition to the library, although marred by 

 a considerable percentage of error. Referring to my own genera, for 

 example, I find the geiuis " Achromata," attributed to me, should be 

 Achromoia. and, in a similar way, the genus " Alegafaronus " should be 

 Megarafonus, " Oh'a " should be Olla, " Pontalomata " should be Ponto- 

 malota and "' Ulloporus " should be Uloporus. The genus " Eomedon," 

 similarly assigned, was not described by me. Eulitriis, " Casey," should 

 be Eji/iinis, -Sharp. I do not recollect having founded any such genera 

 as '' Sponidium " and " Typitium," which are attributed to me, and further 

 verification is necessary. The genus Ty/oderina, Say, seems to have been 

 overlooked in all the lists that I have been able to consult ; it is an 

 im])ortant genus of Curculionidoe. The names Delius, /sogiossa, Orus 

 and Phalacropsis, ])roposed by me, have been repeated by other authors, 

 and, as these genera appear to be valid, the latter names will have to be 

 changed. The name Ditaphrus, Csy., repeated later by Sharp, is, how- 

 ever, a synonym, and Sharp's name will therefore remain valid, unless it 

 be considered better to have no two names alike, even though one of 

 them may be a synonym, which in the writer's opinion is the preferable 

 policy regarding genera, although unnecessary in the case of species.
