48 Mr. G. R. Crotch's Chronological 



(Edemera is unquestionably 0. femonita, and the modern 

 CEileiuera of Schmidt should be re-named. Serropalpus 

 is here described from Melandrya canaliculata. 



Fabricius, in the Ades cle la Societe d'Histoire Naturelle 

 de Paris, describes several genera, some of which are 

 quoted from his previous paper ; many misprints appear 

 to occur ; the two new ones are Cyloniuin and Lygdus, 

 afterwards altered to Colydiam and Lyctiis. 



Fabricius, in the first volume of his Entomologia systema- 

 tica, adds the genera Parnus [ = Dryops, Oliv,], and 

 Heterocerus. The latter is quoted from Bosc, who how- 

 ever has nowhere described it. 



Hellwig, in Schneider's Magazin, characterizes Myceto- 

 phagus and SyncJiyta, the last being a name given to 

 include three genera which he had formerly separated, 

 and hence having no type. 



Kugelann, in the same work, proposes the genus Ser- 

 rocerus [ = Dorcatoma, Herbst] . 



Schneider, also in the same work, proposes || Elater- 

 oides for Halloinemis humeralis, and || Pentatoma for Li odes 

 humeralis ; both names were, however, pre-occupied. 



Herbst, in the fourth volume of his Natursysteni, des- 

 cribes seven new genera: Megatoma, Vorlcatoma {D. dres- 

 densis) , Pselaplnis, Korynetes [K. violaceus) , Trichodes 

 [^ = Clems, Geofl'.], Krypiophagus {Triplax cenea), and 

 II Strongylus. Of these Strongyhis was pre-occupied ; 

 I Megatoma was founded on a male character only, and 

 I Jiad no type ; Latreille accepted it, and changed the 

 ( name to Attagcnus (type ^4. iindatus) , then (1810) he 

 formed it into a separate genus (type M. serra) . Corynetcs 

 is identical with Necrohia, and does not include the C. cceru- 

 leus, De Geer. Cryptophagus is clearly formed on Triplax 

 cenea, and has only two of the modern genus Cryptopha- 

 gus in it, together with other forms ; Paykull, who next 

 defined the genus, gives the dissections from Triphyllus 

 punctattis. 



1793. Herbst, in the fifth volume, continues to esta- 

 blish eight new genera. Lotridlus {L. longicornis) , 

 Katerctes (K. atcr) , Byzophagiis, Mouotonia (Jf. striata), 

 Bitoma {B. unipwictatn) , Eccoptogaster [= Scolytus, 

 Geoff.], Platypus, and Triplax. hatridius is certainly
