Phlceoxena Chaud. — This genus is due to Chaudoir (Ann. Belg. 

 xii, 1869, p. 145), and is founded on species mostly Mexican with 

 which our Coptodera signata Dej., is associated. In his generic cha- 

 racters Chaudoir says : " Mentum * * * medio sinu dente majusculo, 

 trigono, apice rotundato," but I do not observe any tooth whatever in 

 our species. 



This genus is part of the tribe Thyreopterides. 



Dromius Bon., Apristus Chd., Blechrus Motsch., Metablettjs 

 Schmidt, and Axinopalpus Lee, have not, as far as I am aware, been 

 reviewed by Chaudoir, and are probably a part 'of his intended tribe 

 Dromiides which is merely casually mentioned in his preliminary remarks 

 on the Callidides, (Ann. Belg. xv, 1872). These genera may therefore 

 be passed without further remark than — that the ligula is not always bor- 

 dered in front by the extension of the paraglossae, not even in Dromius. 

 Certain European authors, among them Baron Chaudoir, have rejected 

 the name Axinopalpus for Variopalpus having been misled, evidently, 

 by the date given in the Munich Catalogue. The former genus was 

 published in 1846, the latter in 1848. 



Tecnophilus Chaud., Bull. Mosc. 1877, i, p. 240. — This genus is 

 suggested for those species in our fauna formerly placed in Philotecnus 

 Mann., with which Chaudoir says they have nothing to do. 



" Vu la configuration de sa languette que ses paraglosses ne bordent 

 pas anterieurement, ce genre ne fait pas partie du groupe des Callidides, 

 mais de celui des 31imodromiides dont je n'ai pas encore expose les 

 caracteres qui demandent a etre mieux etudies." 



The ligula and paraglossfe reproduce exactly those of a species of 

 Gallida, as yet undescribed, which resembles umaragdina very closely 

 and differs from it in nearly the same manner that decora and punctata 

 do from each other. 



Callida Dej., EuPROCTUS Sol., Plochionus Dej., form part of the 

 Callidides of Chaudoir, (Ann. Belg. xv, 1872), which has already been 

 sufficiently remarked upon. Several of our species of Callida have 

 been separated to form the genus Sponyoloba Chd., based on sexual 

 peculiarities of the male which seem to me to have had too great 

 value assigned them. Euproctus is represented in our fauna by one 

 species described as Onota trivittata Lee. (PI. IV, fig. 3). 



Philophuga Motsch., contains those species formerly placed in 

 Glycia. They are reviewed by Chaudoir, (Bull. Mosc. 1877, i, p. 243), 

 who leaves us in doubt whether the genus is part of his Callidides or 

 not. They are not included in that essay.
