their respective families Herr Klebs find.s himself un il>le to 

 assign about 33 per cent, of the beetles wliicli he has 

 examined, in s]>iteof their exeollent preservation. Althoii'^^li 

 in consequence of the material ditreretices wiiiLJi they exhibit 

 they can scarcely bclont; to the families already represented, 

 it is nevertheless quite possible that many a representative of 

 the missing families may be hidden away among them. Heir 

 Klebs cites the genus Lyniexilon as an instance of the way 

 in uhich occasionally solitary forms, hitherto unknown as 

 Tertiary, snddeidy turn U]) in some numbers, lie discovered 

 the first amber specimen of Lymexilon in the autumn of 1888 • 

 a year later he had discovered no less than six specimens of 

 the genus, comprising at least three ditferent species. Lif- 

 mexUon is at the present time an extremely rare genus, which 

 lives in rotten oak, and of which only a solitary local species 

 has hitherto been found in Europe. 



Of the Neuroptera, the Phryganida?, of wliich about five 

 thousand examples have been discovered, are the most nume- 

 rous ; next come the llemcrobiidai, with about fifty specimens, 

 the Panorpida^, with twenty-five, and occasional examples of 

 Semblidffi. 



The Orthoptera are represented by nearly two thousand 

 five hundred sj)ecimens, the Biattidte being most numerous • 

 next, arranged in order of frequency, come the Lepismidai 

 Gryllida?, Poduridje, Locustidai, Pseudoperlidte, Phasmidie 

 Forfieulidge, and lastly the Mantida3. No specimens of 

 Campodidae nor Acrididai have as yet been found, thouo-h 

 possibly specimens of Niceletia and Camjjodea may have been 

 included among the larvae. 



Among about one thousand specimens of Pseudoneuroptcra 

 the Termites are most numerous, numbering about two thirds 

 of the whole, while Tin-ipsida?, Psoeida?, Perlarida3, Eplieme- 

 ridse, and Libellulidte are present in about equal numbers, the 

 Psocidai being perhaps somewhat more numerous than the 

 rest. The Embiidf« are very rare. 



The Lepidoptera, to the number of about one thousand 

 specimens, are all with one exception Micros, belonging to 

 the families Tortricidt^i, Tineidas, and Psychida3. The solitary 

 Macrolepidopteron, wiiich is one of Herr Klebs 's recent dis- 

 coveries, is a tolerably large Arctia. 



The Rhynchota, with about twelve hundred examples, 

 exhibit representatives of all the subdivisions, with the excep- 

 tion of tliePediculina. Aphididas and IIomo|)tera (Cicadidas) 

 are the most numerous ; next come tiie Hemiptera, and lastly 

 the Coccidge. Myriopoda, both Chilopo;ia and Chilognatha, 

 are represented by about one hundred and fifty specimens.
