gloss seems to show itself as soon as the skin hardens (equestris, mar- 

 t/an tacea, ferruginea). The like takes place with the blood-red or testa- 

 ceous colour, at the base of the shards, observable in many species ; iu C. 

 vibex alone it appears in individuals newly disclosed, in the rest not till after 

 a greater interval, and that immediately before the metallic gloss, as the 

 author has observed in C. vibex in particular. The species are grouped 

 according to the puncturing of the shards. 



I. The punctures scattered: 1. C. equestris, F. 2, hemisfh&rica, Hbst. 



II. With punctures in rows, 'without regular ridges down the shards. 



A. Lateral rim bent upwards : 3. C. austriaca, F. 4. vittata, F. 



B. Lateral rim flattened out: 5. C. nmrraea, L. 6. sanguinosa, Creutz. 

 (prasina, Hbst.) 7. rubiginosa, Mull, (along with the nearly related, 

 similarly ornamented species of Southern Europe, lata, Suffr., deflorata, 

 111., hexastigma, Kunze, depressa, Heyd.) 8. thoracica, Kug. 9. rufovirens, 

 Suffr., new species, from different parts of Germany. 10. vibex, L. 11. 

 deiiticollis, Suffr., new species, from Northern Germany. 12. chloris, new 

 species, diffused over almost the whole of Germany, with which, perhaps, 

 12 b , C. stigmatica, 111., shoidd be united as a sub-species. 13. C. sangui- 

 nolenta, Mull. 11. lliieola, Creutz. 15. azurea, F. 16. lucida, Suffr. ; a 

 species like the last, very brilliant when Living, found in all its states upon 

 Cucubalus behen, near Ems. 



C. The lateral rim descending abruptly : 17. C. margaritacea, Schall. 18. 

 subreticulata, Meg., from Austria. 19. nobilis, L., with which 19 b , C. viri- 

 dula, Payk., as it seems, should be joined as merely individuals not fully 

 coloured. 20. oblonga, 111., with a kindred new species, C. puucticollis, 

 Heyden, from the south of Europe. 



III. Shards punctured in rows, with regular elevated lines down them : 

 21. C. berolinensis, Dej., distinguished by the yellow colour of the under- 

 side. 22. obsoleta, 111. 23. ferruginea, F. 21. nebulosa, L. 



IV. Shards wrinkled : C. atrata, F. 



Cassida nigra, F., according to the specimens preserved in the Berlin 

 Museum, should be referred to C. equestris, as individuals blackened by 

 unknown causes. The specimen described by Herbst, which is in Schiip- 

 pel's cabinet, according to information communicated orally by the pos- 

 sessor, does not belong to the same species, but is a similarly disfigured C. 

 nebulosa. 



Delocrania cossyphoides, Guerin (Mag. Zool. Ins., pi. 131), from. Brazil, is 

 a new form of Hispa, with elongated slender body, and the side rims of the 

 corslet and shards dilated simultaneously, those of the corslet extending 

 much further forwards than the head, which, therefore, is seated in the bot- 

 tom of a deep bight. Another new Hispa is H. (Uroplata) leseleurii, Guer. 

 (Mag. Zool. Ins., pi. 143), from Cayenne, remarkable for the form of the
