Medon uniformis, n. sp. 



Pale reddish-castaneous ; antennae, palpi, and legs flavous. Elytra and 

 abdomen with rather dense and somewhat golden pubescence, much less distinct 

 on head and prothorax. 



Head distinctly transverse, hind angles gently rounded off, with a very 

 narrow median line ; punctures dense and very minute. Antennae short, second 

 joint slightly longer than third, the following ones to tenth feebly increasing 

 in width and mostly transverse. Prothorax transverse, front angles almost 

 square, the hind ones strongly rounded; punctures as on head. Elytra slightly 

 longer than wide, slightly wider than widest part of prothorax, about once and 

 one-half its length, and with somewhat larger and more sharply-defined 

 punctures. Legs not very long, front femora stouter than the others and very 

 feebly dentate. Length, 3.5-3.75 mm. 



Hah. — Queensland: Mulgrave River (H. Hacker). 



A small, pale, subopaque species, certainly close to M. dehilicornis (and 

 consequently belonging to the subgenus Hypomedon) but more opaque, larger, 

 head conspicuously larger and less closely applied to the prothorax (owing to 

 the longer neck) ; the elytra also, although slightly paler than the prothorax, 

 are simply paler, rather than flavous. I have checked the types with a cotype 

 and some other specimens of dehilicornis from Hawaii, India, and Japan (iden- 

 tified by Drs. Cameron and Sharp), and the differences appear constant. It 

 is about the length of M. incomptiis, but is less robust and elytra not con- 

 spicuously bicoloured, being at most very feebly infuscated about the scutellum. 

 M. Ignitus, another almost uniformly coloured species, is described as being 

 smaller, 3 mm., and with strong punctures ; although in the description only 

 the abdomen is mentioned as "laeviusculo," in the table the species is associated 

 with M. cinctus as having "Corps tres hrillant," whereas this species is very 

 dull. The tip of the abdomen of each of the types is contracted, but on one of 

 them (evidently a male) part of a notch is visible; from the other the notch 

 appears to be absent. The middle of the prothorax is slightly produced to 

 form (apparently) part of the neck; it has a very feeble median line, of which 

 the only fairly distinct portion is a short shining line near the base. Except 

 on the abdomen there are very few hairs scattered about.

A specimen, from the Daly River, probably belongs to this species, but 

 differs from the description in having the head and prothorax of a very dark 

 castaneous-brown, although appearing black at a glance.

Five specimens from New South Wales and Victoria (one was taken from 

 a nest of the ant Dolichoderes scaharidus) appear to belong to this species, but
