might have seen them ; and lastly, might not have considered 

 them distinct. Of course I do not make any further use of the 

 great weight of his opinion, than to bespeak caution in deter- 

 mining upon such new German species as he has passed over. 



Sturm next took up the group in his ' Deutschlands Fauna ' in 

 1839. He added two new species to the first group (Choleva) — 

 spadiceus, Dahl. in litt., and castaneus, Andersch. in litt. — both 

 of which have been adopted by subsequent authors, although, for 

 reasons which I shall afterwards give, I think the latter is only 

 a variety of angustatus. He also added the badius of Meg., the 

 brunneus of Knoch, and the anisotomoides of Spence to the list 

 of species found in Germany. 



In 1841 Prof.Heer (in his 'Fauna Helvetica') described besides 

 most of those already known, two new species, montivagus and 

 ambiguus, and reproduced the alpinus, Gyll. The descriptions of 

 the two former are too short and vague to allow of their being 

 satisfactorily identified from the book, and I have not seen 

 authentic specimens. M. Kraatz in his revision also states, that 

 he has been unable to make them out, but holds that the alpinus 

 of Gyllenhal has been rightly revived. 



Several detached descriptions of individual species also ap- 

 peared from time to time. 



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

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

 humeralis, 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, rotundicollis is the Kirhii 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. 



Rosenhauer (Beitrage zur Insectfauna Europas) in 1847 de- 

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

 tristis) and C. varicornis, 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 orientalis, to the list. All three appear to be 

 good species.
