Type and paratypes in the U. S. N. M. (no. 23641) ; paratypes 

 in the Coll. of the Tropical Insect Survey in charge of Mr. 

 Harold Morrison and in my collection. 



Described from numerous examples from Santiago de las 

 Vegas, Cuba, May, 1918, sent to Mr. Harold Morrison of the 

 U. S. Bureau of Entomology by Dr. Mario Calvino, Director 

 Estacion Experimental Agronomica de Cuba. Dr. Calvino states 

 that these were collected from the Royal Palm (Oreadoxa regia) 

 on the young growth of which they are doing serious damage. 



The revised family and the subfamily characters may be sum- 

 marized as follows : 



Family— THAUMASTOCORID^. 



Tarsi two-segmented, first segment minute. Apex of tibia 

 with or without a lobular membranous caducous appendage ; 

 if the latter then are the tarsal claws furnished with aroha. 

 Coxae globular, widely separated ; acetabulse closed up. Ros- 

 trum short apparently three-segmented. Venter of the male 

 posteriorly asymmetrical consisting of eight segments besides 

 the genital ; genital segment obliquely antrorse along either the 

 right or left side of venter. Venter of female with the seventh 

 segment covering the genital. Spiracles situated ventrally( ?). 

 Odoriferous orifices invisible. Membrane without veins. 



Subfamily I. THAUMASTOCORINM. 



Apex of tibia provided with a lobular membranous caducous 

 appendage. Tarsal claws devoid of arolia. Jugse much longer 

 than tylus. Clavus ampliated apically. Commissure about as 

 long as the scutellum (Thaumastocoris australicus Kirkaldy 

 and Baclosygum depressum Bergroth) .
