112. genus BAJULATA BALL 



Bajulata Ball, Proc. Biol. Soc. Wash. 46. 26 (igSS). 



Characters : The species bajula Goding was described in the genus Evashmedea but was early 

 removed to Vanduzea in which genus it stood for niany years but it always occupied a niore or less 

 anomalous position in that genus because of the swollen rounded elevations on thedorsum. In igSS 

 Ball erected the genus Bajulaia for its accoiiimodation. Its has since remained the single representative 

 of the genus. The characters of the species which may be considered generic are as follows : head 

 subquadrate, broader than high, roughly sculptured; base strongly sinuate; eyes ovate ; oceUi conspic- 

 uous, a little farther removed from each other than from the eyes and situated sHghtly below a hne 

 drawn through centers of eyes; inferior margins of genae strongly sinuate; clypeus convex, swollen, 

 extending for half its length below inferior margins of genae. Pronotum low, convex, with two large 

 dorsal swelhngs, one behind the other, the first bilobed and the second simple; metopidium convex, 

 broader than high; no suprahumerals ; humeral angles strong, triangular, blunt; median carina faintly 

 percurrent; sides of pronotum punctate but not ridged and extended downward to cover about one-third 

 of the tegmina ; posterior process heavy, tectiform, bhint, just about as longas the abdomen and reaching 

 a point halfway between internal aiigles and tips of tegmina. Tegmina about twothirds exposed ; 

 hyaline with the basal and costal areas sparingly punctate; veins strong and punctate; five apical and 

 three discoidal cells; median apical cell transverse with the base obtusely angulate and petiolate; apical 

 hmbus narrovv. Legs simple; hind tarsi longest. 



The genus is closely related to Vandiizea from which, however, it is at once distinguished by the 

 dorsal lobes.

113. genus HYGRIS STAL 



Hygris Stal, Rio Jan. Hem. II : 29 (1862). 



Characters : A genus erected to accommodate a single small, inconspicuous species chaiacter- 

 ized particularly by the low, convex pronotum and the character of the almost entirely exposed tegmina 

 which shows only two discoidal cells in the corium. Head triangular, convex; base stiongly sinuate; 

 eyes small, twice as bioad as high; ocelli inconspicuous, equidistant from each other and from the eyes 

 and situated on a line drawn through centers ofeyes; inferior margins of gen£e sinuate ; clypeus extend- 

 ing for inoie than half its length below inferior maigins of genae. Pronotum convex, highest in front, 

 slightly depressed in middle, somewhat broader behind; metopidium straight, broader than high; no 

 suprahumeials; humeial angles strong, tiiangular, blunt; median carina strongly percurrent ; sides of
