wings ash-grey, longer and broader than the body, and incumbent : thorax 

 three-horned, two of which are placed in front behind the eyes, about as 

 long as the thorax, strong, erect and curved outwards ; the third horn 

 rises from the posterior margin of the thorax, extending in a gentle arch 

 the whole length of the body and tapering to the apex. Stal notes that 

 the type has the lateral margins and apical spine of the scutellum sordid 

 whitish. Walker's G. terminalis is thus described : " Black, clothed with 

 tawny hairs ; head and pronotum roughly punctured : head convex very 

 short, transversely subfusiform, a little narrower than the pronotum, 

 undulating along the hind border, retuse in front, on each side of 

 the face whose hind border is semicircular and occupies much less than 

 half the length of the face ; clypeus prominent, retuse : pronotum thick 

 in front rising vertically above the head, indistinctly ridged ; shoulders 

 very obtusely angular, not prominent ; above them are two long, stout, 

 prismatic, diverging, acute horns which are curved backwards, especially 

 towards the tips ; their sides are slightly concave, their inner and outer 

 sides are of equal breadth, their hinder side is narrower ; behind them 

 the pronotum is armed with a long, slender, smooth, acute triangular 

 horn which is slightly curved downwards and extends to the tip of the 

 abdomen : abdomen above with hoary reflections : tibiaa pitchy ; hind 

 tarsi tawny : wings very pale lurid ; a narrow pale brown streak on the 

 fore-border near the tip of each tegmen ; two discoidal areolas ; veins 

 tawny : wings colourless, veins black." Body long 6-8 millims. 



Fairmaire notes that he cannot separate from this species smaller 

 ones of which the horns are very acuminate and hardly recurved, and 

 others in which the horns are relieved and oblique. M. vicarius, "Wal- 

 ker, is one of those in which the horns are short. 



Reported from India : the Indian Museum possesses specimens from 

 Calcutta, Sikkim.
