Coleopterous Genus Macrotoma. 379 



described below. It differs from M. ElUoti in having the legs 

 and antennce much more spinose ; the apical joints of the 

 latter differently and more strongly grooved, and relatively 

 shorter, the third joint being about equal to the five apical 

 joints taken together ; whereas in M. Ellioti the third joint 

 is not much longer than the three apical joints together. The 

 thorax is rather more convex and less dull, owing to the 

 punctuation not being quite so much crowded; the discoidal 

 impressions are smaller, narrower, and less conspicuous, and 

 the smooth border at the base is very narrow and obscure. 



Macrotoma Ellioti^ sp. n. 



cJ . Fuscous, with the elytra brown ; the apex of the an- 

 tennae and the posterior legs, and the tarsi somewhat pitchy. 

 Head coarsely punctured between the eyes, with the usual 

 frontal impression not very deep, inipunctate ; the back of 

 the head closely and finely granulose. Antenna reaching to 

 two thirds the length of the elytra ; the basal joint about 

 twice as long as broad, closely and very coarsely punctured : 

 the third joint 14 millim. long, as long as the fourth, fifth, and 

 two thirds of the sixth joints taken together, the surface 

 somewhat wrinkled and punctured, the front margin and 

 under surface with short spines ; the fourth to eightii joints 

 shining and sparingly punctured above ; the ninth more finely 

 and more closely punctured ; the apex of the ninth and the 

 apical joints opaque and longitudinally rugose : there is a 

 small opaque spot on the underside of the apex of the third 

 joint; and on the outer side of the apex of the fourth, fifth, 

 sixth, seventh, and eighth joints there is a small, slightly 

 elongate opaque spot ; the eighth has also a small spot at the 

 base, and the whole side of the ninth is opaque. Thorax one 

 fifth broader at the base than at the apex, dull, densely and 

 finely punctured, with two triangular shining marks on the 

 disk. Immediately outside each of these marks is a small 

 round rugose spot, which emits a rugose line towards the 

 sides and directed backwards. The middle portion of the 

 base is shining and strongly punctured, with a smooth line 

 emitted from its fore margin to the middle of the disk, and at 

 each side there is a rugose line directed forwards towards the 

 sublateral rugose spot. Trie marginal spines are short and 

 not very numerous. The elytra are rusty brown, a little 

 paler towards the apex ; densely and moderately finely rugu- 

 lose-punctate and extremely finely granular, the granulation 

 becoming gradually more distinct towards the base, till near 

 the scutellum the surface is rough. Each elytron has tlie 

 usual four lines. The sutural angle is not spined. The
