 Macroma gloriosa, Westuj. (nee Mohnike), Thes. Ent. Oxon. 1874, 



p. 14, pi. vii, fig. 1. 



Shining black, with the head and prothorax crimson, the latter 

 decorated with three small black spots placed in a triangle on 

 each side and the front and hind margins very narrowly black. 



Rather short, broad at the shoulders, with the upper surface 

 very convex and strongly depressed in the region of the scutellum. 

 The Jiead is coriaceous, with the clypeus rather transverse, parallel- 

 sided and almost straight in front, and the mentum horizontal. 

 The pronotum is punctured at the sides, narrow in front and broad 

 behind, with the posterior angles well-marked and the base very 

 obtusely angulated in the middle. The scutellum is acute at the 

 apex, but not produced as in M. melanopus, nigripennis, &e., and 

 the elytra are almost impunctate, with the apical area hmited by 

 a zigzag carina in front and feebly strigose ; the anterior half of 

 the suture is depressed and the posterior half elevated. The 

 pygidium is rugose, slightly bilobed at the apex, with a sharp 

 median carina and an elevation on each side produced backwards 

 as a sharp spine. The lower, like the upper surface, is almost 

 smooth, and the fifth ventral segment is twice the width of those 

 preceding it and bent downwards at an angle to them. The 

 sternal process is very broad. The external face of the hind tibia 

 is produced and bifid and the hind tarsus is short and thick. 



The male is apparently unknown. 



Length 25 mm. ; hreadth 14 mm.
