8o HOMOPTERA 



was misprinted in the original description biit which was afterward corrected) and from the characters 

 given ia his description, we assume that the insect suggests in general facies the Old World genus 

 Gargara which contains a large number of small inconspicuous forms of about the size given for iholoidea. 

 Goding's original description which is quite complete but which is not accompanied by a figure, is as 

 foUows : 



« Densely and evenly punctate and densely golden pubescent. Head triangular, longer 

 than broad, rounded forward from base and curved downward and backward from middle to 

 apex; base sinuate; ocelli distant from base, on a line with superior margin of and approaching 

 eyes which are large and prominent. Pronotum tumid, forming a dome-like elevation, unarmed 

 above humerals and in front, with a strong elevated percurrent carina but not foliaceous; hume- 

 rals prominent ; seen from the side the outline is semicircular from base in front to posterior 

 process; base of posterior process broad, covering scutellum, seen from above gradually acumi- 

 nate to apex which extends beyond tip of abdomen and interior angle of tegmina; seen from the 

 side it is roundly elevated from base to apex and tectiform and moderately high. gradually ele- 

 vated in a curve above apex of abdomen. Tegmina one-half as broad as long, basal half 

 opaque, apical half sordid hyaline vitreous, apices obliquely narrowed to obtuse exterior angle; 

 three longitudinal veins emitted from base of corium, radial forked well toward apex to receive 

 exterior discoidal cell, ulnar veins simple, space between radial vein and costa broad coriaceous 

 and densely punctate ; two discoidal cells, nearly equal, interior cell sessile, its base a transverse 

 venule between ulnar veins behind middle; five apical celis, third sessile with base truncate; 

 basal half clavus coriaceous, punctate. not gradually acuminate, venation not easily seen. Wings 

 with four apical cells. Abdomen robust; legs slender, tarsi all short. » 



The very small size and the upturned tip of the posterior process seem to be the most distinctive 

 characters b}' which the genus can be most readily separated from the more nearly related genera of 

 the tribe. 



Typo tholoidea Goding. 



Geographical distribution : Known only from the following single species : 



I. tholoidea Goding, Journ. N. Y. Ent. Soc. XXXIV : 246 (1926). Ecuador. 



41. GENUS EUMELA STAL 



Eumela Stal, Bid. Hem. Syst. 559 (1867). 



Characters : Rather large brownish or grayish insects with smooth rounded pronotum and 

 heavy straight posterior process. The head is subquadrate with base sinuate and the ocelli equidistant 

 from each other and from the eyes. The pronotum is convex, rounded in front, with a strong median 

 carina and a well defined circular impression on each side. The dorsum is punctate and pubescent. 

 The posterior process is heavy, straight, rounded above and sharp at its extremity, extending almost to 

 the tips of the tegmina. The scutellum is completely covered by the sides of the pronotum. The 

 tegmina are entirely free, usually smoky or fuscous hyaline in color with the venation more or less 

 obscure; there are five apical and two discoidal cells and a wide limbus. The legs are simple and the 

 tarsi uniform in length. 



Type semiacuta Stal. 



Geographical distribution : The three described species of the genus have been reported 

 only from Brazil.
