the types in being shining and paler ; on five of them the elytra and legs are 

 pale flavous, the prothorax slightly darker, and the head slightly more reddish, 

 but certainly not dark ; on the others the elytra are as dark as the prothorax, 

 and the head is distinctly darker but more castaneous than piceous. The species 

 in appearance somewhat resembles Mcdon dcbilicoriiis. but it is at once dis- 

 tinguished by the antennae, the joints after the second on that species are com- 

 paratively short and transverse, on the present species they are decidedly longer 

 and thinner, so that if drawn backwards the antennae would extend to the base 

 of the prothorax, instead of scarcely to the middle. The subopaque appearance 

 of the types may have been due to improper treatment ; if it is natural the 

 Queensland specimens should probably be regarded as representing a variety, 

 or a distinct species.

Medon obsoletus, Nordm. 

 Several specimens were obtained from fallen leaves, at Cairns, that appear 

 to agree perfectly with British and European specimens of this species. It was 

 first recorded as Australian in the catalogue by Bernhauer and Schubert, and 

 eight synonyms and varieties are there noted. 



Medon ochraceus, Grav. 

 This cosmopolitan species was apparently first recorded as Australian in 

 the same work as the preceding one ; Australian specimens before me are from 

 Queensland (where it is frequently attracted to lights) and Tasmania. Six 

 synonyms of the species are recorded. 



Medon debilicornis, Woll. 



Widely distributed in Australia, although first noted as Australian in the 

 catalogue by Bernhauer and Schubert, who record four synonyms of it. A 

 rather highly-coloured figure of the species is given under the name of Litlio-

Medon varicornis, Blackb. 



This is probably only a slight variety of M. tristis. 



Medon camponoti. Lea. 

 Six specimens of this species were taken from a nest of Camponotus 

 aeneopilosiis at Glen Innes.
