1879.] 9 



One small wing has been described by Dr. Heer as being that of 

 a Hymenopterous insect, but, for the reasons given in my second* 

 paper, I am of opinion that this supposed Hymenopterous wing pro- 

 bably belonged to an insect of another Order. 



The Neuro'piera included 6 species of Termites — referred by Heer 

 to two generaf — and one species of LibelliilidcB, uMschna Sngeni, 

 which, with the exception of Gynacantha ])lagiata,% is probably larger 

 than any known living species, and is especially interesting as being 

 the oldest known dragon-fly, if we except that very doubtful fragment 

 from the American Coal-measures, which has been referred by Scudder§ 

 to the genus Lihellula. 



The Orthoptera comprised 3 species of BJattidcs {Blattina formosa, 

 S. angustata, and S. media), 3 species of Acridiidce {^Gom-pliocerites 

 Huchlandi, Acridiites deperditus and A. liasinus), and one species of 

 Forjiciilidcs {Baseopsis forficulina) , which differs much from all living 

 forms. 



The Semiptera belonged to the families Cercopidce, Cicadidce, and 

 Bygaeidce. 



The Coleoptera are represented by 116 species, which are distri- 

 buted amongst the following families, viz. : Carahidce, Gyrinidce, Niti- 

 dulidcB, Peltidce, Cryptophagidce, BathridiidcE, Mycetophagidce, Byrrliidcs, 

 IIydropliilid(B,Apliodiidce,Biiprestidce,JElaterid(je, TelephoridtB, CistelidcB, 

 CurculionidcB, and Ohrysomelidce. 



The BuprestidcB are represented by no less than 33 species, referred 

 by Heer to seven genera, two of which still exist, whilst the others 

 {^Glaphyroptern, Micranthaxia, Buprestites and Olirysobotlirites) are 

 extinct. Of the 33 species of Buprestidce, 16 are placed by Heer in the 

 extinct genus Glaphyroptera. 



The ElateridcB are represented by 10 species, the most abundant 

 of which is Elaterites vetustus. 



Of the ByrrMdoB, four species have been determined, three of 

 which — Byrrhidium arcuatum, B. morio, and B. troglodytes — are said 

 to be amongst the most abundant || of the Schambelen fossils. 



The carnivorous beetles are represented by 29 species, including 

 OarabidcB (11 species), Telepltoridce (3 species), &c. The Hydrophilidce 

 comprise 15 species, and the Gyrinidce 6 species, all of which latter 

 family are remarkable for their small size. 



The Lamellicornia and Chry some! idee are poorly represented, and 

 the Longicornia,Xylophaga, BracheIytra,aTid GoccineUidce, are altogether 

 absent.
