and Gyrinidoc of Australasia. 405 



tively much broader than the former ; it is larger but more elongate 

 proportionally than the latter : the coloration also separates it from 

 either species. 



The two examples of R. Blanchardii that I know of Avere received 

 by Mr. Bakewell from Victoria ; one, through this gentleman's kind- 

 ness, is now in my collection. 



3. H. JoJinsonii, n. sp. 



H. ovatus, brevis, punctatus, testaceus ; thorace ad mediimi nigro-fusco, ad 

 latera testaceo ; elytris quatuor aut quiuque lineis insequalibus fiiscis a 

 medio ad apicem, pedibus autennisque flavis. 



Long, corp, 2 lin., lat. 1 lin. 



Broadly ovate, somewhat depressed, thiclcly punctate, of a testaceous 

 or flavo-testaceous colom- : head with two oblique medial foveae, in 

 colour testaceous : thorax broad, transverse, in colour dark fuscous, 

 the margins being testaceous : elytra broad, thickly and finely punc- 

 tate ; near the shoulders are traces of pubescence ; in colom* pale tlavous, 

 with four or five longitudinal lines of fuscous extending fi-om the 

 middle to the apex ; these lines are fi-equently inteiTupted and irregu- 

 larly suffused : abdomen and underside thickly punctate, rufo-fuscous : 

 legs and antentice flavous. 



Separated from other species at once by the pale-testaceous colour 

 of its elytra and black thorax, as well as by its smaller size. From 

 the district of Victoria. 



4. H. australis, n. sp. 



H. ovatus, latus, brevis, dense et minute punctatus, rufo-testaceus, thorace 

 ad basin aliquando subobfuscato ; elyti-is obsolete unistriatis, apicem 

 versus obfuscatis. 



Long. Corp. 2 lin., lat. 1^ liu. 



Ovate, short, broad, finely punctate throughout, of a rufo-testaceous 

 colour : head very finely and obsoletely punctate : at the base of the 

 thorax are, in the two examples before me, traces of fuscous marking : 

 elytra broad, thickly punctate throughout ; on either side of the sutm'e 

 is an obsolete stria, more distinct towards the base, but vanishmg as it 

 approaches the apex : irregularly shaped and indistinct fuscous markings 

 are apparent on either elytron near the apex : legs and antennae pale 

 rufous. 



H. amtralis closely resembles H. Blanchardii, from which it is 

 mdeed only to be separated at first sight by its distinctly smaller 

 size ; a little examination will, however, shoAV that the thorax is 

 relatively somewhat narrower, and the markmgs on the thorax and 

 ilytra much loss pronounced and %\ell defined. From II. Caledonian
