Mr. A. Murray's Monograph of the genus Catops. 9 



In 1832 a species from the Morea was described by Brulle in 

 the ' Expedition Scientifique de Moree ' under the name of C. 

 humei'alis, which seems to belong to the subgenus Choleva. 



Chaudoir (Bulletin de Moscou, 1845, iii.) described two new 

 species as being found in the neighbourhood of Vienna, longi- 

 pennis and sericatus. M. Kraatz does not consider these to be 

 distinct species, but joins them respectively to nigricans and 

 sericeus, 



Kellner in ' Stettin Ent. Zeit/ 1846, No. 6, described four new 

 species, C, longulus, rotundicollis, coracinus, and subfuscus. As 

 already mentioned, rotundicoUis is the Kirbii of Stephens. Kraatz 

 observes that subfuscus is not distinguishable from alpinus, Gyll. ; 

 and from a specimen of longulus submitted to me by M. Kraatz, 

 I am satisfied that it is only a variety of tristis. 

 i Eosenhauer (Beitrage zur Insectfauna Europas) in 1847 de- 

 scribed C. abdominalis (considered by Kraatz to be a variety of 

 tiistis) and C. varicorniSj which, although very close to sericeus, 

 appears to be a good species. 



Redtenbacher in his ' Fauna Austriaca ' (1849) gives a synopsis 

 of the species of the genus, but without adding any new species. 

 Dr. Aube in 1850 added C. meridionalis and quadraticollis, besides 

 Catopsimorphus orientalisj to the list. All three appear to be 

 good species. 



The only works remaining to be noticed are M. Kraatz's revi- 

 sion of the genus published in parts in the ' Stettin Ent. Zeitung ' 

 in 1852, and the 'Faune Entomologique Franyaise' now in 

 course of publication by MM. Fairmaire and Laboulbene. 

 Although the latter work is subsequent in date, I shall notice it 

 first; partly because none of M. Kraatz's new species are to be 

 found in it, and partly because M. Kraatz's revision contains a 

 full summary of all the European species hitherto described, and 

 is therefore well suited for closing this part of my paper. 



The authors of the ' Faune Ent. Frany. ' adopt the name Cho- 

 leva, Lat., in deference to priority, instead of Catops. They do not 

 introduce any new species. They adopt the four subdivisions 

 laid down by Erichson, and in addition attempt to break up the 

 second subdivision into smaller sections. These subdivisions are — 



1. "Posterior angles of corselet obtuse," in which they place 

 C. picipes, grandicollis, and alpina. 



2. " Posterior angles of corselet right-angled, more or less 

 pointed," containing C.fusca, morio, nigrita, quadraticollis, tristis, 

 chrysomeloides, rotundicoUis, and fumata. 



3 . " Posterior angles of corselet pointed, a little produced behind" 

 which contains umbrina, nigricans, and scitula. 



These divisions appear to me to group the species in too un- 

 natural a manner to be of service even as an artificial mode of
