The emargination of the clypeus is very well marked, but 

 evidently shallower than in M. sordidus, Boisd., the bisinuation 

 of its sides somewhat stronger than in that insect. The lateral 

 margins of the thorax are each cut into about 20 teeth, each of 

 which is scarcely shorter than one of the thoracic setae. As the 

 setiferous tubercles are raised above the surface of the insect, 

 it has no punctures rightly so called. The elongate tubercles 

 form about 18 rows on the elytra, each row containing less 

 than 30 tubercles. The set® are of a pale brown colour, but 

 are not particularly conspicuous. The middle tooth of the 

 front tibia is fairly well defined, and is about intermediate in 

 position between the base of the tibia and the apex of the ter- 

 minal tooth. The widening of the fifth and ninth (and in a 

 less degree of several other) intervals between the rows of 

 granulations on the elytra is very noticeable. 

 Taken by Mr. B. S. Eothe, of Sedan, S.A. 

 N.B. — The South Australian Museum, Adelaide, contains a 

 specimen ticketed " S.A.," which I cannot regard as distinct 

 from that sent me by Mr. Eothe, although it is larger (11 mm.), 

 somewhat darker in colour, and has the granulations on the 

 surface of the thorax not quite so strong. I have also seen 

 two specimens taken by Mr. J. Anderson on Boston Island. 

 Jf. rugosipes, sp. nov. Brevis, convexus, rufo-piceus, minus 

 nitidus ; clypeo triangulariter, minus f ortiter exciso lateri- 

 bus obliquis vix sinuatis ; prothorace creberrime punctato, 

 antice angustato, lateribus rotundatis vix crenulatis, 

 angulis posticis subdentiformibus, basi fortiter lobata ; 

 elytris seriatim punctulatis tuberculatisque ; tibiis anticis 

 obtuse minus fortiter tridentatis ; tibiis intermediis et 

 posticis in medio margine externo bi-vel trituberculatis ; 

 unguiculis simplicibus. Long., 10 mm. 

 The shape of the thorax is remarkable in this species. From 

 the front, which is the narrowest part, it widens with gently- 

 curved margins nearly to the base, and then is rapidly nar- 

 rowed, with a strong curve, to the posterior angles, which are 

 dentiform ; but behind the posterior angles the thorax is quite 

 strongly emarginate in such manner that the middle of the 

 basal portion forms a conspicuous lobe. The sculpture of the 

 elytra resembles that of M. major, mihi. The external outline 

 of the anterior tibiae might almost be called " strongly 

 bisinuate" rather than "tridentate." On the intermediate and 

 hind tibiae two or three of the asperities on the middle of the 

 external edge exceed the rest in prominence much more notice- 

 ably than is usual in the genus. 



I obtained a single specimen of this insect some years ago 

 from Victoria, but the exact locality of its capture is unknown 

 to me.
