190 AEGUS DILATICOLLIS. 



the sides flattened, diverging towards the base. The front 

 angles prominent and rounded, the basal angles broadly- 

 rounded, thence nearly straight, the basal margin faintly 

 sinuate. The upper surface densely covered with large punc- 

 tures which become more or less confluent towards the 

 base and the sides and which bear a short rufous bristle. 

 The lateral margins are thickly fringed with short rufous 

 bristles. The scutellura is strongly punctured. 



Elytra considerably narrower than the thorax, the shoul- 

 ders but slightly prominent, the sides regularly convex ; 

 each elytron with seven impressed striae composed of a row 

 of confluent punctures; the interstices are flat and provided 

 with two rows of large punctures, the two outermost however 

 with only one row ; the sides are covered with regular rows 

 of somewhat smaller punctures. All these punctures bear a 

 short rufous bristle, and the lateral and apical margins are 

 fringed like the thorax. 



Under surface and legs dark rufous and rather remotely 

 covered with bristle-bearing punctures, with the exception 

 however of the sides of the prosternum which are glossy 

 and impunctate. 



Length of the female 14 mm. — Agreeing with the cf but 

 broader and more strongly punctured ; the elytra regularly 

 densely punctured, without distinct interstices, but showing 

 tine longitudinal glossy lines. The head smaller and the 

 mandibles not toothed, but provided on the inside with a 

 triangular smooth dilatation of the lower margin, which dila- 

 tation is faintly emarginated near the tip of the mandibles. 



Cardanus Boileavi^ n. sp. cf. 



Length (with mandibles) 13 mm., breadth at the shoulders 

 4 mm. — A shining black species like laevigatus H. Deyr. 

 (Moluccos) and alfurus Gestro (Andai: New Guinea) but 

 larger and quite different as to the shape of the head, the 

 sculpturing of the elytra, etc. 



The head is emarginated between the lateral front angles 

 and the ocular canthus, the latter is regularly rounded with
