48 Mr. C. 0. Waterhouse on 



Macrotoma sodalis^ Waterli. 



This species was described from a single female example 

 from Fianarantsoa (Ann. & Mag. Nat. Hist. 1880, v. p. 413). 

 The British Museum has just received three examples (two 

 males and one female) which I think must be referred to this 

 species. The female differs from the type in being larger, 

 19^ lines long ; the thorax is rather less narrowed anteriorly, 

 the sides have some short acute teeth ; and the spine at the 

 posterior angle is curved and stronger than in the type. 



The males differ from the female which accompanied them 

 in having the legs more robust and the tarsi broader ; the 

 antennffi extend nearly to the apex of the elytra ; the basal 

 joint is more robust, coarsely punctured ; the third joint is 

 rather stout, a little narrowed to its apex, strongly and closely 

 punctured, and beset with very short acute spines, especially 

 below ; the fourth, fifth, and sixth joints are sparingly punc- 

 tured, the seventh more thickly punctured, the eighth to 

 eleventh opaque and longitudinally channelled. The femora 

 and tibias have the edges set with strong acute spines ; but the 

 anterior femora have few or no spines above ; the anterior 

 tibia} are opaque and rough. 



One of the males has the spine at the posterior angle of the 

 thorax straight and very acute ; the other specimen has this 

 spine stronger and curved. Length 15 lines. 



All the specimens have the thorax sparingly clothed with 

 yellowish pile, and the elytra beset with stiff hairs. 



Supposing all these specimens to be referable to M. sodaJis^ 

 the question now arises, how do the males differ from M. 

 o&scMr«, Waterh. {I.e. p. 410)? M. ohscura was described 

 from a single male example from Antananarivo, 22 lines 

 long, and of a blackish colour. The males just received are 

 smaller, brown, and have the anterior tibiffi furnished with 

 comparatively few spines arranged in a single line on each 

 edge ; in M. ohscura the spines are close together^ and are 

 arranged in a double series on each edge. 



M. ohsciira and M. sodalis may hereafter prove to belong 

 to the same species ; but at present it appears better to 

 consider them distinct.
