these impressions and border and median line convex. Elytra 

 oval, considerably wider than elytra (7'8x4-8 mm.), convex; 

 sides gently ampliate behind shoulders; base truncate; humeral 

 angles rounded; apex sinuate on each side; four inner interstices 

 convex, first narrow, third impunctate; lateral interstice placed 

 in the deep marginal channel, narrow, punctate along its course. 

 Length 14-5, breadth 4-8 mm. 



Hah. : N. 8. Wales — Blue Mountains (Springwood, Sloane ; 

 Wentworth Falls, Fletcher.) 



A specimen from the Tweed River has been sent to me by Mr. 

 A. Lea under the name of M. ater, Casteln.; from which M. 

 convexus differs by its narrower and more convex form; the pro- 

 thorax with the sides less ampliate at their widest part, and much 

 less strongly sinuate posteriorly, the anterior angles projecting 

 less from the sides of the neck, the base narrower with the angles 

 less sharply rectangular, the lateral basal impressions shorter; the 

 elytra proportionately narrower, the sides less ampliate behind 

 the humeral angles and less rounded, the fifth stria impressed near 

 apex; the metasternal episterna longer. 



Note. — Meonis ovicollis, Macl., is not a member of this genus; 

 I have examined the type and found it to be a species of 

 Darodilia. 



Genus C y c l o t h o r a x. 



Cyclothorax cordicollis, n.sp. 



Robust; head narrow, hevigate; prothorax convex, cordate- 

 elytra punctate-striate, base (narrowly), lateral and Ijasal declivi- 

 ties smooth. Black, nitid ; legs testaceous, tibife sometimes a 

 little infuscate; antennse infuscate, basal joint testaceous. 



Head convex; front biimpressecl, bicarinate on each side, inner 

 carina extending backward to level with middle of eyes, wide 

 anteriorly, very narrow posteriorly near anterior supra-orbital 

 puncture; eyes hemispherical, prominent. Prothorax much wider 

 than head, a little broader than long (12x1-3 mm.), widest 

 before middle (at anterior marginal puncture), greatly narrowed 

 to base; sides roundly ampliate, lightly sinuate just before base;
