488 Herr R. Klebs on the Fauna of Amber. 



Ghironomus lias at least 40 species. 



Of DoHchopodidjB Low was able to distlngaisli 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. 8pecies 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 antennai branched like the antlers of a stag*. 



Of the Hymcnoptera all the groups are represented, with 

 the exception of the Braconidge and Evaniadai. The Uro- 

 veridge, 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. Lucanidae. 



Hydrophilidae. Scarabjeidae . 



Clavigeridse. Cebrionidae. 



Anisotomidse. Melyridae. 



Sphaertidffi. CioidfB. 



Scaphidiidae. Pimiuellidie. 



Rhyssodidae. Diaperidae. 



Mycetophagidse. Helopidse. 



Thorictidae. Lagriidae. 



Throcid*. Rhipiplioridae. 



Georyssidae. Meloidas. 



Parnidae. Salpingidje. 



Heteroceridae. Corylophidae. 



But besides the Coleoptera which have been allotted to 



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

 cesses as antenncB. They are most likely specifil ciiticular developments, 

 as in the case of the remarkable genus EJaphomi/ia, founded by Saunders 

 for certain forms discovered by VVallace in the Malay Archipelago, the 

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

 shaped chitinous processes springing from the head, quite distinct from 

 the antennae, which are in the normal position. — Tbaxsl.]
