is clothed with yellow pubescence, finely and delicately punc- 

 tured, but the punctuation is more indistinct in the middle 

 area. Legs shining and sparingly punctured. The femora 

 furnished with a few slender spines both above and below. 

 The tibia3 have a few spines on the inner side. 

 Length 24 lines. 



" Prionus cr-enatus, Fabr." 



There is in the Museum collection a single male example 

 from M. Chevrolat's collection which bears the Dejeanian 

 label " Macrotoma lugubris^ raihi, h. in India orient. D. 

 Latreille," and Chevrolat's label, " Pri. crenatus, F. S. El. 2. 

 264." It differs from M. absurda only in having the thorax 

 and elytra more convex, with the dorsal marks less impressed. 

 It is perhaps not distinct from M. absurda. I see no refer- 

 ence to P. crenatus, Fabr., in Gemminger's Catalogue. The 

 Fabrician description would apply to this insect fairly well ; 

 but I think it doubtful whether " magnus " would have been 

 applied in this group to a species only 22 lines long. 



I^OTE. — M. sicjnaticoliis, Ellioti\ inscripta, plagiata, absurda, 

 and M. cenet'pennis^ compose a small group allied to M. 

 luzonum, F., characterized by the males having a closely 

 punctured opaque metasternum, with a triangular shining area 

 in the middle. 



Macrotoma Fisheri, sp. n. 



^. Ferruginous; the head, three basal joints of the an- 

 tennae, and the anterior femora nearly black ; the intermediate 

 and posterior legs and all the tarsi pitchy. The whole of the 

 metasternum and the parapleurai clothed with fulvous-yellow 

 pubescence. 



Head opaque, moderately strongly and closely ocellate- 

 punctate on the forehead, densely and finely granulose poste- 

 riorly ; the deep excavation between the antennal tubers with 

 only a few punctures. Antenna} reaching to two thirds the 

 length of the elytra ; the basal joint strongly but not very 

 closely punctured ; the third joint 12 millim. long, flattened 

 above, not very closely or strongly punctured, the underside 

 moderately asperate. The fourth to seventh joints smooth 

 above, the seventh more closely punctured than the preceding 

 joints ; the eighth to eleventh joints opaque ; there is an 

 opaque spot on the underside of the apex of the third joint ; 

 the fourth joint is opaque at the side for nearly the whole 

 length, and the fifth, sixth, and seventh joints are opaque at 

 the side for their whole length, the opaque portion having a
