noted between the Pyrochroidae and Oedemeridae were 

 rather vague. Associated with it are three other species, one 

 of which has very different antennae, but in other generic 

 details is in agreement with it. They differ from all the 

 European Pyrochroidae in the Museum in having the eyes 

 lateral and entire, elytra almost parallel-sided (at any rate 

 not conspicuously dilated posteriorly), with narrow epipleurae 

 continuous from base to apex, and with much larger and 

 more conspicuous punctures. In the various works I have 

 consulted some latitude appears to be allowed in the claws of 

 both families ; in the present genus they are certainly not 

 simple, neither are they bifid, as the basal swelling is 

 nowhere pointed. I consider it belongs to the same family as 

 Techmessa ruficoUis, and as that genus was referred to the 

 Oedemeridae by Bates and allowed to remain in it by Cham- 

 pion, it appears desirable to refer the present one to that 

 family. (43) The species are all flat and winged, and black (or 

 purplish-black) and rusty red ; in general appearance much 

 like many Lycides, of the Malacodermidae. The clypeus (at 

 least its front portion) appears to be of the same consistency 

 as the labrum ; that is to say, rather soft. Although the 

 front coxal cavities are widely open behind, it is usually 

 necessary to remove a leg to see a cavity clearly, as the front 

 of the mesosternum is produced on to the base of the pro- 

 sternum so that each coxa is surrounded partly by the pro- 

 sternum and partly by the mesosternum. The species may 

 be tabulated as follows : — 



Antennae not serrate monilicornis 



Antennae serrate or pectinate. 



Elytra with sharply-defined costae ... - costipennis 



Elytra with vaguely-defined elevations. 



Prothorax entirely pale serraticornis 



Prothorax partly black apicalis 



Morpholycus apicalis, Macl. (formerly Pseudolychus). 



There are two specimens (including the type) of this 

 species in the Australian Museum ; < 44 ) they were described as 

 being black except for part of the elytra, but both have the 

 prothorax obscurely reddish at the sides. They are males, 

 and have the antennae strongly serrated or subpectinate after 

 the second joint; the eleventh joint (missing from the types) 



(43) In his recent revision of the Pyrochroidae (Ann. and Mag. 

 Nat. Hist., 1914) Blair states definitely that P. apicalis, Macl., 

 belongs to the Oedemeridae, and some of the family characters he 

 gives : eyes emarginate for the insertion of the antennae, and 

 claws simple certainly exclude it from the Pyrochroidae. 



(44) And I have seen others from Mount Tambourine and the 

 Tweed River.
