AMPHIMELA. 
A. australis, Blackb. I have received from Mr. Masters an 
example taken near Sydney which I hesitate to separate from 
this species although it differs markedly in coloring, its prothorax 
being entirely of a clear yellow color and its antenne entirely 
pitchy-black. It is also of somewhat different form being a 
wider insect with its greatest width slightly behind the middle of 
the elytra; this difference of form may be sexual. Even as a 
variety it seems distinct enough to bear a name so I propose to 
call it “var.? piceicornis.” 
XENIDIA. 
The following species seem to be referable to this genus which 
has not previously been reported as Australian. Unfortunately 
it is not possible to be quite certain in identifying Xenzdia with- 
out an authentic type as its author (Dr. Baly) does not say 
whether its front cox are closed behind. The following are the 
leading characters of the species described below: front cox 
closed behind: anterior four tibiz unarmed (Dr. Baly gives no 
information regarding the front tibie) ; transverse sulcus of pro- 
thorax feeble or wanting ; claws appendiculate ; hind tibize very 
much as in Plectroscelis but with an even wider sulcus, and not 
furnished with a tooth externally; basal joint of hind tarsi 
longer than the following two together. 
X. picticornis, sp. nov. Late ovalis; nitida; fortiter convexa ; 
subtus picea ; supra cupreo-purpurea, antennarum articulis 
3° 4° 11° que plus minusve testaceis, pedibus plus minusve 
piceis vel rufo-piceis (femoribus posticis supra fere nigris

corpus paullo brevioribus, sat gracilibus, apicem versus 
paullo incrassatis [articulo 1° modico, 2° quam 1* dimidium 
longiori, 3° quam 1" sublongiori, 4° quam 3" maris haud

thorace fortiter transverso, transversim leviter sulcato (sulco 
fortiter punctulato) et utrinque impresso, minus perspicue 
(sulco transverso excepto) punctulato, antice leviter angus- 
tato, lateribus sat fortiter marginatis leviter arcuatis paullo 
pone marginem anticum angulatis ; elytris leviter (marginem 
versus fortius) striatis, striis fortiter punctulatis, interstitiis 
planis (marginem versus convexis) subtiliter punctulatis ; 
tibiis posticis dilatatis fortiter sulcatis, sulci margine 
externo fortiter crenulato ; tarsorum posticorum articulo 
basali ceteris conjunctis «quali. Long., 141; lat., 41. 
The coloring of this species,—especially the pallid (in some 
examples almost white) apical joint of its antennse,—distinguishes 
it from its previously described congeners.
