366 NOTES ON AUSTRALIAN COLEOPTERA. 



posticis minutis subrectis ; scutello triangular! ; elytris spar- 

 sim subtiliter punctulatis ; tibiis mucronatis (anteriorum 

 mucrone brevi inconspicuo) ; tarsorum posticorum articulo 1° 

 ceteris conjunctis sequali ; unguiculis aj)pendiculatis ; aceta- 

 bulis anticis postice clausis ; elytrorum ejnpleuris longe ultra 

 medium continuatis. [Long. 11, lat. g line.

ENDOMYCHID.-E. 



Mycella clavicornis, sp.nov. 



Nigro-senea, prothorace femoribusque (his basi picea 

 excepta) rufis ; subtilissime sat crebre punctulata; prothorace 

 quam breviori fere duplo latioii ; antennis corpore vix tertia 

 parte brevioribus, clava corapressa, articulis ultimis 2 sat 

 fortiter transversis. [Long. 3?, lat. 2 lines. 



The prothorax is of about equal width across the base and the 

 front ; the latter is very strongly concave the front angles being 

 much produced but not sharp ; the sides are gently convex from 

 the front to behind the middle and thence slightly concave to the 

 base which is nearly straight but with the hind angles (which are 

 rather sharp) slightly produced hindward and outward ; the disc 

 is moderately convex ; the lateral portions are considerably explan- 

 ate with a well-defined thickened margin which is continuous 

 across the base where it is preceded by a narrow deep transverse 

 furrow. The elytra at their widest part (the middle) ai-e quite 

 twice as wide as the prothorax ; they are less than half again as 

 long as their greatest width and their sides are strongly rounded. 

 The last ventral segment is emarginate in the middle, the emargin- 

 ation being preceded in one sex by a longitudinal keel. The 2nd 

 joint of the tarsi is certainly not longer than wide, but in spite of 

 tJiis character being at variance with Dr. Chapuis' diagnosis of the 

 genus, I think I have rightly placed this species, which seems to 

 be very different in colour and absence of marking from M. lineella, 

 Chap., the description of which deals with colour and markings 

 only.
