Fam. Malacodermidae. 



Metriorrhynclius ramicoruis sp. nov. — Fig. 1. 



J* Black; protborax, scutellum and elytra brick-red. 



Head with rostrum rather long (more than half the iengtb 

 of prothorax). Antennae rather long, second joint minute, 

 third to tenth of moderate length, but each with a long 

 ramus, eleventh about twice the length of nonramose portion 

 of tenth. Prothorax moderately transverse, conspicuously 

 seven-areolate, apex obtusely produced in middle, sides gently 

 dilated to near base, where they are slightly incurved, but 

 hind angles slightly produced and acute. Elytra parallel- 

 sided; with regular double rows of transversely oblong punc- 

 tures, the alternate interstices somewhat elevated. Length, 

 14 mm. 



Hab. — Queensland: Yarrabah (Dr. E. Mjöberg). Type 

 in Stockholm Museum. 



On the antennae the ramus itself is slightly longer than 

 its supporting tenth joint, on the others it is about twice 

 as long; the median areolet of the prothorax is narrow, and 

 has a slight longitudinal medio-basal elevation. The entirely 

 påle prothorax, scutellum, and elytra, with other parts black, 

 long rostrum and ramose antennae readily distinguish from 

 most species of the genus; in my table^ would be associated 

 with M. nigripes, M. uniformiSj and M. textilis, the two former 

 have very different antennae in the male. 



A female from Queensland (H. J. Carter), and one from 

 Cairns (E. Allén), evidently belong to the species, they differ 

 from the type in having antennae shorter, and the third 

 to tenth joints strongly serrated (subpectinated), with the 

 abdomen not notched. They differ from the female of M. 

 textilis (the only sex of that species at present known), by 

 the different sides and base of prothorax, with the carinae 

 less pronounced, but in particular by the strongly serrated 

 antennae, even the third joint being strongly produced on 

 one side of apex; on textilis that joint being hardly produced 

 to one side.
