215. Genus MICREUNE Walker 



Micreune VValker, Journ. Linn. Soc. Lond. i. gS (i856). 



Characters : A small genus of large conspicuous insects characterized by the long porrect 

 anterior horn which bears slender recurving branches, and the posterior process which usually arises 

 from near the base of the pronotum but does not conceal the scutellum or impinge on the tegmina. 

 Head subquadrate, wider than high; base weakly arcuate and sinuate; eyes very large, globular and 

 protruding; ocelU large, conspicuous, located near the upper outer angles of the head, four times as far 

 from each other as from the eyes and situated far above a line drawn through centers of eyes; inferior 

 margins of genae short and sinuate; clypeus very large, extending for at least three-fourths its length 

 below inferior margins of genas, diamond-shaped, very broad in the middle, tip pointed. Pronotum 

 elevated into a porrect horn which is branched at the top; metopidium cone-shaped, wider than high; 

 median carina obsolete; humeral angles large, triangular and blunt; anterior pronotal horn turrete, 

 porrect, extending upward and forward over the head, branched at the top into two slender branches 

 longer than the horn itself which bend backward over the body ; posterior process slender, arising from 

 near the base of the pronotum, nearly straight, tip sharp and reaching beyond the internal angles of the 

 tegmina; scutellum entirely exposed, much longer than broad, tip bifurcate. Tegmina long, narrow, 

 semiopaque; base narrowly coriaceous and punctate; five apical and two discoidal cells ; tip rounded; 

 apical limbus narrow. Legs slender and simple; hind tarsi longest. 



Type formidenda Walker. 



Geographical distribution : This is a Malayan genus with one doubtful species reported 

 from East Africa.

216. GENUS LEPTOBELUS STAL 



Leptobelus Stal, Hem. Afr. IV : 86 (1866). 



Characters : A very distinct and rather striking genus characterized particularly by the fact 

 tbat the posterior process arises from high up on the anterior pronotal horn just below or between the 

 lateral branches. Head subquadrate, wider than high; base hghtly arcuate and sinuate; eyes very
