255. GENUS INSITOR DISTANT 



Insitor Distant, Faun. Brit. Ind. App, 176 (igi6). 



Characters : The type species of this monotypic genus shovvs a peculiar pronotal character 

 which at once distinguishes it from the other genera of the tribe. The disc is elevated and compressed 

 with the anterior and posterior dorsal margins angulate, and the median carina extending upward in a 

 sharp crest. Other characters which are probably generic are as foUows : Head subquadrate, twice as 

 broad as high; base feebly arcuate and sinuate; eyes globular; ocelH large, about equidistant from each 

 other and from the eyes and situated above a line drawn through centers of e\'es; inferior margins of 

 gena; horizontal and rounded; clypeus extending for half its length below inferior margins of genae, tip 

 rounded. Pronotum anteriorly prominently elevated, laterallj' flattened, the anterior and posterior 

 margins of the disc roundly angulate and compressed; no suprahumerals; metopidium vertical with the 

 crest overhanging the head; median carina strongly elevated; humeral angles large and rounded; 

 posterior process heavy, concavely depressed in the middle and convexly ampliate posteriorly, tip blunt 

 and not reaching the internal angles of tlie tegmina; sides of mesonotum narrowly exposed on each side. 

 Tegmina broad and mottled; base strongly coriaceous and punctate; veins strong; five apical and two 

 discoidal cells; tip rounded; apical limbus narrow. Legs long and slender; hind tibia; lightly curved; 

 hind tarsi longest. 



Type exemplificatus Distant. 



Geographlcal distribution : This genus is known only from the type species from India.

256. GENUS YASA Distant 



Yasa Distant, Faun. Brit. Ind. 74 (1907). 



Characters : This is another monotypic genus characterized, as far as may be judged by the 

 type species, by the peculiar venation of the tegmina, which show only three large apical cells, and by 

 the very short, slender posterior process. Head subquadrate, wider than high; base feebly arcuate and 

 sinuate ; eyes globular and protruding ; ocelli large, a little farther from each other than from the eyes and 

 situated above a line drawn through centers of eyes; inferior margins of gense rounded; clypeus broad, 

 extending for half its length below inferior margins of genae, tip truncate. Pronotum convex, gibbous, 

 without suprahumerals but with a short, weak posterior process; metopidium sloping, much wider than 

 high; median carina obsolete; humeral angles large and blunt; no suprahumerals; posterior process 

 short, slender and recurved, its tip not nearly reaching the internal angles of the tegmina; sides of 

 mesonotum visible but not spinose. Tegmina long, pointed, mottled hyaline; base broadly coriaceous 

 and punctate; veins rather indistinct ; three apical and two discoidal cells; tip pointed; apical limbus 

 broad. Legs slender; hind tibiae strongly curved; hind tarsi longest.
