258. GENUS GARGARA AMYOT AND SERVILLE 



Gargara Amyot and Serville, Hemip. 537 (1843). 

 Maepopa Buckton, Mon. Memb. 2^7 (igoS). 



Characters : This is the largest genus in the family both in number of species, of which we are 

 convinced there are yet many to be described, and in numbers of individuals which in some regions 

 are to be found in almost unbelievable multitudes. On account of its size, it would be very desirable 

 to subdivide this genus, if only to facilitate systematic work, but we can find no natural characters on 

 which such a subdivision can be based. The representatives of Gargara are all small, robust, heavy- 

 bodied, subtriangular iiisects with very distinct generic characters of which the following are the most im- 

 portant : Head subquadrate, broader than long; base arcuate and sinuate ; eyes large and ovate ; ocelli 

 large, conspicuous, equidistant from each other and from the eyes and situated about on a line drawn 

 through centers of eyes; inferior margins of gense sloping and sinuate; clypeus broad, usually extending 

 for at least half its length below inferior margins of genae, tip rounded. Pronotum low and convex, 

 without suprahumerals but with a short, stout, straight posterior process; metopidium sloping, broader 

 than high ; humeral angles broad, triangular and blunt ; median carina usually percurrent but sometimes 

 almost obsolete; surface of pronotum varying in character but usually punctate or pubescent or both; 

 posterior process short, heavy, straight, tectiform, impinging on both scutellum and tegmina, with the 

 tip sharp and reaching just about to the internal angles of the tegmina; scutellum broadly exposed on 

 each side. Tegmina broad, hyaline, base usually punctate and pubescent, corium often mottled with 

 various colors; veins strong; five apical and two discoidal cells; tip rounded; apical limbus broad. 

 Hind wings with three apical cells. Legs short, stout and heavy; hind trochanters unarmed ; femora 

 cylindrical; tibiae triquerate; hind tarsi longest. 



Type genisln: Fabricius. 



Geographical distribution : This is a very cosmopolitan genus with as vvide a distribution 

 as may be found in any genus in the family. Representatives are to be found in practicallj' all parts of 

 the Old World. In spite of this fact, however, and of the large number of species, there is a surpris- 

 ingly small amount of variation within the group.
