parts are sharply defined but somewhat variable ; on the head 

 they consist of a transverse bilobed space at the base and an 

 irregular one in middle, two fairly large angular spots on 

 prothorax (slightly nearer base than apex, and distinctly 

 nearer sides than each other), most of elytra, apical half (or 

 more) of antennae, knees, tarsi, and tips of tibiae; on one 

 specimen the scutellum, clypeus, and a spot on each palpus 

 are dark, and parts of its under-surface are obscurely mottled. 

 On each elytron the paler portions are roughly and irregu- 

 larly circular, so that they enclose dark spaces, of which one 

 is basal and the other subapical. 



Calomela (Platymela) sticticollis, Baly. 



The ground-colour of the prothorax and under-surface of 

 this species varies from pale-flavous to reddish-castaneous, the 

 six prothoracic spots are usually conspicuous, but occasionally 

 the two outer ones are absent, occasionally the legs are 

 entirely pale. Baly described the inter-eoxal process of the 

 prosternum as truncate ; it is certainly not conspicuously 

 bilobed as on most species of Calomela, but as it certainly is 

 gently incurved to its middle the expression (as a generic 

 feature) might be somewhat misleading. He also recorded 

 the species as from Melbourne, but probably in error; the 

 species is fairly common from the Richmond River in New 

 South Wales to the Coen River in Queensland. 



Calomela (Platymela) rufocastanea, n. sp. 



Reddish-castaneous, labrum and basal third of antennae 

 (the apical two-thirds infuscated) flavous; tarsi, and some- 

 times parts of tibiae, more or less deeply infuscated. 



Read with irregularly-distributed punctures, varying 

 from moderately large to small, and larger between eyes than 

 elsewhere; clypeus not depressed, with dense and rather small 

 punctures, its suture distinct but not deep. Antennae rather 

 long and thin, none of the joints transverse. Prothorax 

 more than twice as wide as long, sides gently decreasing in 

 width from base to apical fourth and then more rapidly to 

 apex, front margin gently bisinuate; with irregularly-scat- 

 tered punctures of moderate size and with numerous minute 

 ones. Elytra very little wider than prothorax, with regular 

 rows of not very large punctures, becoming much smaller 

 posteriorly, the interstices with fairly numerous minute 

 punctures; with a vague depression behind each shoulder. 

 Tnter-coxal process of prosternum with a row of punctures in 

 a groove on each side of basal two-thirds, base gentlv incurved 

 to middle. Claim strongly and acutely dentate (almost bifid).. 

 Length, 8-10^ mm.
