49. Genus KRONIDES Kirkaldy 



Kronides Kirkaldy, Ent. XXXVII : 279 (1904). 

 Argante (preoccupied) Stal, Bid. Hem. Syst. 558 (1867). 



Characters : This genus may be recognized at once by the strong curved pronotal horn which 

 is broadly flattened dorso-ventrally and bends downward in front of the head. Head deflexed, subquad- 

 rate, twice as broad as high, almost entirely concealed from a dorsal view by the over-hanging anterior 

 horn, base higher at sides than in the center because of the downward curve of the cephalic margin of 

 the metopidium; eyes large, prominent, extending farther laterad than the sides of the pronotum ; ocelli 

 prominent, somewhat elevated, farther from each other than from the eyes; clypeus extending for half its 

 length below inferior margins of gense. Pronotum low, almost flat above, punctate and shining; anterior 

 pronotal horn strong, broadly compressed dorso-ventrally, extending forward and bending strongly down- 

 ward over and in front of the head, tip truncate ; humeral angles very weak and rounded; median carina 

 percurrent; posterior process broad, flat, gradually becoming acute to the tip which reaches just beyond 

 the internal angles of the tegmina; scutellum entirely concealed. Tegmina long, narrow, opaque, veins 

 more or less obscure; five apical cells, the median one truncate at base ; one discoidal cell; apical limbus 

 broad. Legs simple; posterior tarsi the longest. 



Type incumbens Germar. 



Geographical distribution : The genus is known only from Scuth America and is represented 

 by only five species but the individuals must be very nunierous and easily coUected for they are to be 

 found very cominonly in coUections.

50. GENUS OREKTHOPHORA FUNKHOUSER 



Orekthophora Funkhouser, Journ. N. Y. Ent. Soc. XXXVIII : 4. 412 [19^0). 



Charaoters This genus may be distinguished at a glance by the long, slender,up-tuined anter- 

 ior pronotal horn which is unlike ihat of any other form not only in the subfamily but in the family. 

 The insects are small and slender-bodied with the following technical characters : Head subquadrangu- 

 lar, twice as broad as high; base emarginate in center to accommodate a median downward curve of the
