42 Mr. G. R. Crotch's Chronological 



gave any types (except a few in the Entoniologia Syste- 

 matica emendata) till his final work; where he generally 

 gives the dissection of some one species. Olivier 

 figures the typical species, with its details, in all cases, 

 thus defining many Fabrician genera; unfortunately, he 

 has two or three types in the larger genera. Latreille, 

 however, with that breadth of view which distinguished 

 him, at once saw that the mere multiplication of species 

 had gone far enough, and in 1802 re-defined the existing 

 genera, and added the typical species; this was still 

 more marked in his fourth revision, or " Considerations 

 Geuerales" in which he gives a simple list of genera, 

 with the type species added. I would only mention 

 further, that the utmost laxity prevails in the citations 

 of genera, the references being singularly inexact in 

 point of date; Agassiz's Nomenclator, perhaps the most 

 careful work of the kind, has several hundred inaccu- 

 racies in the Cohoptcra alone, the various works of 

 Latreille being an especial stumbling-block. 



1735. Linnaeus in the first edition of his Systema 

 NaturcB, gives twenty-three genera of Coleoptera, one othei* 

 {Lampyris) being placed in the Hemiptera. 



The principal species is generally indicated, but that 

 this is not to be relied on, is shown by the list of Swedish 

 species published in the following year, in the " Acta 

 tfpsaliensia," where their complete heterogeneity is mani- 

 fest. The genera now founded are, Blatta {Blaps morti- 

 saga) , Dytiscus, Meloe, Forjicula (including Staphylinus) , 

 Notopeda {Alatis oculatus) , Mordella, Curcidio (no type), 

 Buceros {Oryctes nasicornis) , Lucanus, Scarahceus (includ- 

 ing Dcr))iestes) , Dermestes {Necrophorus vespillo) , Cassida, 

 Chrysomcla, Coccionella, Gyrinus, (including Ilaltica) , Ne- 

 cydalis {Clerus forniicarius) , Attelahus {Tenehrio molitor) , 

 Cantharis [C. vesicatoria) , Carahus, Cicindela {Buprestis 

 ruariana) , Leptura, Ccrambyx, Buprestis. 



Now on elucidating these further by the FAenchns ani- 

 inalium, we find Veniiestcs including D. lardarius, as it 

 clearly ought to do, being an old name of Gcedart's for 

 that species. Necydalis is a magazine, including Bhagium, 

 Clerus, Pariagams and Attelahus coryli. Attelahus is almost 

 worse, since besides Tenehrio it includes Spondylis, one 

 Elater, and three Chrysonielce. Cicindela includes the 

 modem Cicindela and Buprestis. Buprestis consists of 

 Carahus and Callidiuut.
