488 Herr R. Klebs on the Fauna of Amber. 



Chironomus Iia3 at least 40 species. 



Of Dolichopodidas Low was able to distinguish at least 

 sixty-eight different species. The rest of the families of 

 Diptera, with very few exceptions, also have their represen- 

 tatives in the fauna of amber. Species have been discovered 

 quite recently which attract attention owing to their peculiar 

 shape, and which, to the best of Herr Klebs's knowledge, are 

 widely separated from existing forms. He instances a large 

 Dipteron lately discovered which possesses extraordinarily 

 large antennae branched like the antlers of a stag*. 



Of the Hymcnoptera all the groups are represented, with 

 the exception of the Braconidje and Evaniada;. The Uro- 

 veridffi, however, are limited to two large species of Sirex 

 which Herr Klebs has lately discovered. 



The Coleoptera, with about four thousand examples, 

 possess representatives of a number of families. Out of a 

 total of seventy-five families twenty-six are so far missing. 

 These are : — 



Cicindelidae. Lucanidse. 



Hydro pbilidne. Scarabajidae . 



Clavigeridse. Cebrionidre. 



Anisotomidae. MelyridiB. 



Spbaertidne. Cioidoe. 



Scapbidiida?. Piminollidte. 



Rhyssodida?. Diaperid*. 



Mycetopbagidse. Ilelopida?. 



Thork-tida). Lagriidaj. 



Throcida?. Kbipipborid;p. 



Georyssidae. Mt^loida?. 



Parnidse. Salpiuuridoe. 



HeteroceridBB. Corylophidas. 



But besides the Coleoptera whicli have been allotted to 



• [In all probability Herr Klebs is mistaken in speaking of these pro- 

 cesses as antemKT. Tboy are most likely special cuticular development^, 

 as in tbe case of the remarkable genus Elnphomiiln, f )unded by Saunders 

 for certain forms discovered by Wallace in tlie .Malay Archipelago, tlie 

 types of which are in the British Museum. These have a pair of antler- 

 shaped cliitinous processes springing from the head, quite distinct from 

 the antennte, -which are in the normal position. — Transi..]
