new genera and species of Tenebrionidce, Sfc. 283 



tured, Avith numerous minute specks or granules scattered 

 on the intervals; elytra gently convex; base emarginate, 

 not keeled up to the scutelhim ; humeral angle prominent 

 and acute ; sides expanding to behind the middle, thence 

 rather rapidly, but scarcely sinuately, narrowed to the 

 apex, Avhich is not produced nor divaricate ; more or less 

 finely seriate-punctate, the intervals minutely punctulate 

 and sometimes delicately rugulose ; abdomen shining 

 black ; episternum of mesothorax faintly punctured ; pro- 

 sternum not concave between the coxas ; legs and antennas 

 as in the preceding species, except that the anterior 

 femora have not the tomentose line down their inner 

 face. 



The 2 has the antennas and legs less robust, joint 3 

 of the former shorter ; and the tibise not thickened at the 

 apex. 



Long. 7 — 7^ lin. 



Antananarivo. 



Dolichoderus approximatus, n. sp. 



Very near to the preceding, but the upper surface is 

 not of a silky black ; the antennary orbits are less promi- 

 nent and more rounded ; the head is more uneven, and 

 the punctuation thoiigh shallow is large and coarse ; the 

 sides of the prothorax are a little more rounded, the lateral 

 margins Avell marked throughout, and there are no minute 

 bright specks or granules scattered between the punctua- 

 tion ; the elytra are a little less convex, the lines of 

 punctures are rather coarse and are placed in lightly-im- 

 pressed strias ; the intervals impunctate ; and the episterna 

 of the mesothorax are coarsely punctured. 



Long. 8 lin. 



Fianarantsoa. 



Dolichoderus distinctus , n. sp. 



Shining black, head short, broadly truncated in front, 

 finely and obscvu-ely punctured ; prothorax very convex, 

 a cluster of rather large shallow punctures on the disc 

 nearer the apex than the base, the rest of the surface being 

 very nitid and minutely and remotely punctulate ; apex 

 truncate, fi-ont angles not at all prominent ; lateral margins 

 distinct throughout ; sides slightly and somewhat sinuately 

 expanding from the apex to beyond the middle, thence
