Coleopterous Germs Macrotoma. 381 



Macrotoma plagiata^ sp. n. 



Nearly black, with the elytra fuscous. Third joint of the 

 •antennai as long as the fourth, fifth, and sixth taken together. 

 Thorax dull, densely and finely punctured, with two shining, 

 sparingly punctured, very slightly raised patches on the disk, 

 with a rather deep impression on the. inner side of each. On 

 the side there is a small punctured shining spot, and at the 

 base a transverse shining space (also punctured) having a 

 smooth line proceeding from the centre to the middle of the 

 disk. In one specimen this basal space is united to the lateral 

 spot by a shining line. The teeth at the sides of the thorax 

 are extremely short. 



Length 20 lines.

This species is very close to the preceding, but, besides the 

 difference in colour and the relative length of the third joint 

 of the antennae, it differs in having the disk of the thorax 

 more convex, and the two dorsal shining spots are more ovate 

 and slightly above the surrounding surface ; the front legs 

 and basal joints of the antennai are less rough, and the spines 

 on the posterior femora and tibiee are very minute, the latter 

 appearing at first sight smootli. 



Macrotoma ahsurda^ Newm. 



This species is extremely close to the preceding. All the 

 examples, however, before me have the intermediate and 

 posterior femora more or less furnished with small spines on 

 the upper edge, and the third joint of the antennae is only 

 equal in length to the fourth, fifth, and a little more than half 

 the sixth taken together. The examples vary in length from 

 13 (the type) to 24 lines. 



The female is rather more elongate than the male. The 

 antennte reach to about the middle of the elytra, are slender 

 and shining, the apex of the ninth and the whole of the tenth 

 and eleventh joints being opaque. There is an opaque spot 

 on the underside of the apex of the third and following joints, 

 the fifth and sixth have also a spot at the base, and on the 

 seventh, eighth, and ninth the basal and apical spots nearly 

 unite. The thorax is smooth and shining above, with a few 

 punctures at the base, and on the fore part of the disk are two 

 oblique impressions with a slight longitudinal swelling be- 

 tween the impression and the lateral coarse punctuation ; a 

 little removed from this swelling there is a second, small, 

 round, smooth, elevated spot ; there is a well-marked bat 

 small impression in the middle of the base. The metasternum
