HORN EXPEDITION-COLEOPTERA. 
This species seems to be common all over Southern Australia, but appears to 
have escaped description hitherto. Its pallid upper surface distinguishes it from 
the described Australian species except elojigatiilus, Mach, viaculiceps, Mach, and 
Iffvigatus, Blackb., from which it is at once distinguishable mter alia by its larger 
size and the much better defined puncturation of its upper surface. Its colouring 
is much like that of the European P. viaritwws, Thoms., but it is much smaller 
than that species, with the apex of its palpi infuscate and the puncturation of its 
upper surface less strongly impressed. It should be noted that the ill-defined 
patches of infuscation on the upper surface are variable, and that in some examples 
the head is entii’ely infuscate. Named after Mr. John Anderson, of Port Lincoln, 
who has done good service in the investigation of the Coleoptera of Eyre’s 
Peninsula, and in whose company I first met with this insect.

P. deserlicola, sp. nov. (18). Ovalis; nitidus; piceo-niger, pialpis antennis 
tibiis tarsis et capitis prothoracis elytrorumque marginibus lateralibus rufis vel 
rufo-testaceis; supra-subtiliter (in capite prothoraceque subtilissime) punctulatus, 
elytris puncturis nonnullis (his seriatim dispositis) paullo majoribus impressis. 
Long. 2 1. Lat. 1 1. (vix). 
In colour and markings (except in its tibia? being reddish) this species closely 
resembles the European P. ovalis, Thoms., but it is of narrower and more elongate 
build and its puncturation is very much finer (so fine indeed that a strong lens is 
required to see it at all). I do not know of any other Australian (or indeed 
European) Philhydrus with puncturation so fine.

HYDROBATICUS. 
H. Tatei, sp. nov. (16). Ovalis; minus convexus; minus nitidus; supra 
sordide testaceo-brunneus, piceo-adumbratus ; subtus piceo-niger, antennis palp)is 
tibiis tarsisque sordide testaceis; capite prothoraceque fortius crebre (quam H. 
australis, Blackb., magis crebre minus fortiter) punctulatis, puncturarum inter- 
stitiis baud puncturis minutis impressis ; prothorace transverse subquadrato antice 
quam postice paullo angustiori ; elytris punctulato-striatis, interstitiis quam 
prothorax multo minus fortiter punctulatis subconcavis, interstitiis singulis 
utrinque linea subtili elevata marginatis. Long. 2—2| 1. Lat. 4—1,
