mens are in condition that allows of their labial palpi and ligula 

 being examined. I see, however, no reason to place them else- 

 where than in the genus Gyrophceiia of which they have the 

 facies completely and with which they agree in the large promi- 

 nent eyes, pronotum margined at the base and furnished with a 

 few large discal punctures, the sinuate hindmargin of their 

 elytra, the presence of well-defined sexual characters on the sixth 

 dorsal segment of the hind body, 'fee, kc. 



[TACHYPORIDES.] 



BARRONICA. 



The diagnosis of this genus was published in Tr. R, Soc, S.A., 

 1895, p. 202, where I stated that I felt extreme difficulty in deter- 

 mining whether it ought to be placed near Myllcena, or ought 

 rather to be associated with the Tachyjjorides, and gave the balance 

 in favor of the former place. T have since come to the conclusion 

 that the genus is identical with Leiococraspedum, Kraatz, founded 

 for a small Stoq)hylinid from Ceylon, and to which M. Fauvel 

 subsequently assigned a species from N-S. Wales. I have not 

 seen Kraatz's diagnosis of Leucocrasjjedum, but I think I know 

 Fauvel's species as one that I have taken near Sydney, with 

 which my Barronica seems to be congeneric. M. Fauvel places 

 the genus in the Tachyjiorini, and I think he is right in so 

 placing it, as in spite of its extremly Mylkena-\ike facies, the 

 form of its maxillary palpi and the insertion of its antennae are 

 not those of the Gymnusini (to which Myllmna appertains). 



LEUCOCRASPEDUM. 



L. {Barronica) acorpio, Blackb. This species is at once dis- 

 tinguishable from all its congeners known to me (including 

 sidneense, Fauv.) by its antennae entirely testaceous, except a 

 feeble infuscation of the apical joint. A long series of specimens 

 presents no variation in this character.
