ZOOBLAX. 39 



hind angles acute and directed slightly backwards, somewhat in 

 the manner characteristic of the Elatendce ; its upper surface finely 

 and very closely punctured and opaque, but with two rather small, 

 coarsely punctured, glossy depressions in front of the middle and 

 a short band of a similar kind running obliquely forwards from 

 the base on each side. Prosternum, inesosternum and sides of 

 the metasternum very closely punctulate ; a very sharply limited, 

 rather strongly depressed median triangular area of the meta- 

 sternum, sparsely punctulate and glossy. Last ventral segment 

 sinuate or subtruncate at the apex. Other characters almost as in 

 Macrotoma, but with the front legs, especially the tibiae, more 

 elongated. 



5 . Antennae shorter and more slender, with the third joint 

 scarcely asperate. Pronotum coarsely punctured except in the 

 middle ; its hind angles project rather strongly outwards, but 

 not backwards. Sterna less closely punctured ; metasternum 

 without a definite space in the middle. 



This genus is not recognized by M. Lameere, who regards the 

 two species here included in it as forming a small group in 

 the genus Macrotoma, with characters that differ only in degree 

 from those met with in the species of our second section of that 

 genus.

Black, the elytra of a fine rather dark green colour. 



<3 . Head sparsely and rather strongly punctured in front, 

 granulate behind the eyes ; the antennal supports separated by a 

 deep channel grooved at the bottom. Antennae a little longer 

 than the body ; first joint rather short, strongly punctate ; third 

 thickened, broadly canaliculate above and below, spinulose at the 

 lower front margin, nearly three times as long as the first and 

 slightly longer than the fourth and fifth united. Prothorax 

 with the sides feebly denticulate, converging in nearly straight 

 lines from base to apex ; disc strongly raised in the middle, with 

 two small, somewhat glossy depressions anteriorly and a longitudinal 

 median one near the base ; the rest of the surface finely and very 

 closely punctate and opaque. Elytra nitid, closely rugulose- 

 punctate, somewhat raised and covered with small tubercles or 

 granules near the scutellum, spined behind at the sutural angle. 

 Legs long ; first joint of the front tarsus narrow and elongate, 

 much longer than the second and third united. 



$ . Antennae smooth, sparsely punctured, not reaching beyond 

 the middle of the elytra. Pronotum nitid, sparsely and feebly 

 punctured in the middle, strongly and more closely towards 

 the sides ; spinose along the side margins, with a stronger, 

 recurved spine at the hind angles ; the sides not so straight as.
