Species of Coleoptera from Madagascar. 411 



rugulose, without costae, the extreme suture pitchy, the sutu- 

 ral angle with a very small spine. Legs irregularly and 

 sparingly spinose, the anterior femora not spined above ; all 

 the tibice with rasp-like punctures, the four posterior tibia? 

 not spined on the inner margin. 

 Hab. Fianarantsoa {Mr. Shaw). 



Macrotoma asperata, n. sp. 



Fusco-picea, obscura ; capite thoraceque confertissime rugoso ; elytris 



creberrirae minute tuberculatis, sutura spina parva acuta. 

 Long. 15-17 lin. 



$ . Head densely rugose, with an impressed frontal line ; 

 the eyes widely separated. Antennas the length of the elytra, 

 the basal joint rather large, not much narrowed at the base, 

 thickly rugose ; third joint as long as the two following taken 

 together, rather closely asperate-punctate, except at the apex ; 

 the fourth to ninth joints more slender, shining, rather spa- 

 ringly punctured, the tenth and eleventh joints longitudinally 

 finely rugulose. Thorax convex, densely and strongly rugose, 

 transverse, obliquely (but not much) narrowed anteriorly, the 

 margins crenulate, the posterior angles with a distinct acute 

 (but not very prominent) tooth ; the base arcuately lobed in 

 the middle, and with a very slight emargination just before 

 the posterior angle. Elytra subparallel, opaque, very slightly 

 narrowed at the apex, thickly studded all over with minute 

 shining tubercles, especially conspicuous near the base. The 

 sutural angle has a distinct acute spine. Legs compressed, 

 the femora and tibiae rather thickly studded with minute 

 shining tubercles, the posterior femur more smooth ; the an- 

 terior tibiae are not properly spinose ; but on the underside of 

 the outer edge may be seen a few small teeth. The four 

 posterior legs are very similarly sculptured. The fifth seg- 

 ment of the abdomen is widely and rather deeply emarginate. 



$ . This differs from the foregoing in having the antennas 

 a little shorter ; the basal joint is less robust, strongly punc- 

 tured ; the third to sixth joints are shining, sparingly punc- 

 tured ; the third joint quite as long as the fourth and fifth 

 taken together ; the seventh is rugulose at the apex, and the 

 eighth to eleventh are opaque, longitudinally very finely and 

 closely strigose. The posterior angle of the thorax is pro- 

 duced into a strong acute spine ; the sides are scarcely crenu- 

 late. The fifth segment of the abdomen is nearly truncate, 

 scarcely sinuate in the middle. The legs are more slender, 

 shining, sparingly asperate-punctate.
