263. Genus CENTROTOSCELUS FUNKHOUSER 



Centrotoscelus F"unkhouser, Journ. Ent. and Zool. VI : 72 (1914). 

 Arisangangara Katn. Insect World XXXII : 3o (1928). 



Characters : This genus is very distinct because of the fact that the insects have no supra- 

 humerals nor extended humeral angles but never the less have the spines on the iniier surface of the 

 hind trochanters as in the horned genus Tricentrns. We are not able to read the Japanese language 

 and are not entirely satisfied with any translation which \ve have been able to secure of Kato's original 

 description of the genus Arisangargara but from his figures and particularl}' from his characterization of 

 the humeral angles as « corners convex d (translated) and of the hind trochanters with « teeth projecting 

 outward » (translated) we are convinced that Arisangargara must be considered as a synonym of 

 Centrotoscelus. 



Head subquadrate, wider than long; base weakly arciiate and sinuate; eyes globular and pro- 

 truding; ocelli large, prominent, twice as far from each other as from the eyes and situated well above 

 a line drawn through centers of eyes; inferior margins of genae sloping and strongly curved ; clypeus 

 with small lataral lobes, tip swollen, extending for more than half its length below inferior margins of 

 genas. Pronotum low and broad, without suprahumerals but with a well developed posterior process; 

 metopidium sloping, much broader than high; median carina faintly percurrent; humeral angles weak 

 and triangular, not auriculate; posterior process slender, weakly sinuate, tectiform, tip acute and just 

 reaching the internal angles of the tegmina; scutellum well exposed on each side. Tegmina broad, 

 hyaline, base coriaceous and punctate and usually pubescent ; veins strong; five apical and two discoidal
