EUCNEMIDES. 'Revue Critique cle la Tribu des Eucue- 

 mides, par M. Guerin-Meneville.' (Ann. d. 1. Soc. Ent. d. 

 Fr. 2 ser. i, p. 1G3.) This memoir is important, especially 

 in the corrections it gives of many of the " most incompre- 

 hensible mistakes" of Laporte, corrections made even from 

 the very same specimens that Laporte had under his eyes. 

 Besides these, the author has reviewed the genera and 

 species found in the Paris collections. His division of 

 them is as follows : 



I. Tarsi simple, without membranous lobes. 



1 . Antenna? free : either 



() Without the grooves on the under surface of the prothorax : 1. Mckisis, 

 Ol. ; 2. Tharops, Lap. (Isorhipis, Lacord.); S.Nemafodes, Lair.; 4. Xylobius, 

 Latr. (XylopJiilus, Mann., Xyloecus, Serv.) ; 5. Epijilniitix, Esch. ; 6. llypo- 

 ccehts, Esch. (procerulus, Maun.) ; Hylochares (buprestoides, nnicolor mela- 

 sinus) ; 8. Calyptocenis, new gen. ; 9. Emathion, Lap. (Splueroccphaliis, 

 Esch.); or 



(b] With shallow grooves on the prostenium : 10. Microrliayus, Esch, 

 (jiygmtfus, Sahlbergif). 



2. The antenna?, reposing in grooves beneath the lateral border of the 

 prothorax, 



(a) With cylindrical joints : 11. Fornax, Lap. (Lirhagvs, Esch.); 12. 

 Eucalosoma, Lap. (liliiymapliorus, Dej.), 



(b] With saw-like antenna; : 13, Eucnemis, Ahr. ; 14. Gastmulacus, 



(Galba, Latr.), 



(c) With brush-like antennae: 15. Oalbodema, Latr. 



II. Tarsi with long, membranous lobes, on the under side : 10. Galba, 

 Esch. ; 17. Pterotarsus, Esch. 



The larva of Melasis is described and figured ; the author, however, has 

 not observed its most remarkable peculiarity, viz. the absence of maxilla: ; 

 although I have described it several years since. (Vid. Arch. Yr. 7. i, p. 84.) 

 The author is also quite wrong in regarding it as intermediate between the 

 larva; of Bitprestes and Elateres; with the latter of which it has nothing in 

 common. The genera Hypoccelus, Esch., and llylocliares, Lat., are really 

 identical but the author employs both names, applying Hypoccelus to 

 />'//. proceruhis, which Eschscholtz regards, though improperly, as the (\pc 

 of Nematodes, and Latreille had included under llylocliares. According to 

 the author, IJylocfutres includes Ev.cn. crucntatus, Mann., nnicolor, Lat.,
