H. Soisduvali, Cast. I possess a female specimen from Swan 

 Hiver, evidently a Hypliarpax^ wLicli is probably this insect. It 

 differs from the preceding exactly, as TI. Boisduvali is said to 

 differ from ausfralis, Dej.,its thorax being nearly twice as wide 

 as long, with strongly rounded sides, and the elytra wide, 

 (especially behind), with slightly feebler striation. I cannot 

 understand Mr. Masters' reference of H. Boisduvali to csreus, 

 Dej , as the thorax of the latter is said to be rectangular behind. 

 I should say that H. Boisduvali^ Cast, is a good species. 



THENAEOTES. 



T. australis, sp. nov. Piceus ; nitidus ; palpis, antennarum 



basi, prothorace, elytrorum marginibus lateralibus apiceque, 



et pedibus, rufis testaceisve ; antennis elongatis (corporis 



dimidio sublongioribus) ; prothorace transverso postice 



angustato ; elytris striatis, striis latera versus deficientibus ; 



subtus piceus in medio rufescens. Yar., pronoto proster- 



noque in medio infuscatis. Long. If — 2 1. 



The whole upper surface is absolutely devoid of puncturation, 



properly so-called, except a single small puncture on the third 



interstice of each elytron behind the middle ; there are also a 



few obscure coarse impressions in a very strong furrow w^hich 



runs a little within the lateral margin of the elytra, commencing 



about the middle and reaching the apex. The antennae (by 



measurement) slightly exceed half the length of the body, but 



appear even longer to the eye, and are of a fuscous colour 



(except the basal two joints). The thorax is about one-third 



wider than long, is widest just behind the front, and thence 



arcuately narrowed to the base, has basal angles almost 



rounded off and a fairly strong rounded impression on either 



side in front of the hind margin, is extremely finely margined 



at the sides, and pretty distinctly channelled longitudinally. 



Each elytron bears four well-marked stride, outside which there 



is no distinct sculpture, except the lateral furrow mentioned 



above. The eyes are large and prominent. As the specimens 



before me all appear to be females, I can give no particulars 



concerning the tarsi of the male, but as I have Dr. Sharp's 



authority for attributing the insect to Tlienarotes, I suppose 



they are as in T. tasmanicus, Bates. The under surface is 



minutely coriaceous. 



I have met with this insect near Port Lincoln and in the 

 Adelaide district, and have seen specimens taken by Mr. Eothe 

 near Sedan.
