424 Prof. Clir. Anrlvlllins on 



I am indebted to Dr. Ilugli Scott for notes on tlie 

 biology of some of the species. 



Prioninae. 

 1. Macrotoma [Hovatoma) simplex, C. O. Watcrli. (?). 



^ . Head, pronotum, antennae, and legs dark brown. 

 Elytra and undeisidc paler brown. Antennai nearly as 

 long as the body, first joint hardly reacliing behind the eyes, 

 about twice as long as broad, coarsely pimcturcd ; tlnrd 

 joint qnite cylindrical, 8 ram. long, as long as the two 

 succeeding joints united, last joint acuminate, longer than 

 the 10th joint and finely acicnlate-punctate. Mandibles 

 short, moderately punctured in basal half. Head coarsely 

 })unctured, with some short hairs in the broad furrow be- 

 tween the eyes and the antenniferous tubercles. Pronotum 

 broader than long, tapering towards the apex, crenulate 

 ■without spines along each side, with two posterior and one 

 anterior im[iressions on the upperside and three subnitid 

 elevations; coarsely but rather sparsely punctured in the 

 middle, but finely and very densely punctured at the sides 

 and at the anterior angles, nearly glabrous, with a few hairs 

 only in the middle l)etween the elevations ; hind margin 

 convex in the middle and densely ciliate ; hind angles 

 produced and directed obliquely backwards. Scutellum 

 obtusely rounded, brown with blackish margin, glabrous, 

 minutely and sparsely punctulate. Elytra glabrous, rugu- 

 lose-puuctate, not granulose, with three rather obsolete 

 raised lines; the punctures much coarser in the basal fourth. 

 Sterna, especially metasternum, hairy. Abdomen subnitid, 

 sparsely punctate and pilose; last segment broadly emar- 

 ginate at apex and densely ciliated at margin. Legs dark 

 brown, subnitid ; femora thickened at base, front and 

 middle femora spinose beneath and sparsely granulose, hiiid 

 femora nearly smooth; all the femora hairy beneath at base; 

 tibiae somewhat compressed and nearly triangular in section, 

 fore tibiffi densely clothed beneath with long hairs in 

 apical half; fore tarsi dilated, with the first jcjint shorter 

 than the next two joints united, last joint not so long as 

 joints 1-3 united. Length 41 ram.

The male of M. simplex was hitherto unknown, and T have 

 not seen the female. It is, however, very probable that the 

 present male belongs to the same species as the female 

 described by C. O. Waterhouse, as this is the only species
