Family XXVII. MICROPHYSID^ Reuter, 1884, 4, 169. 



Very small depressed oblong (male), broadly oboval 

 (female) species, having the head porrect, inserted in thorax 

 to eyes; antennae 4-jointed; beak either 4-jointed, the basal 

 joint very small, or 3-jointed ; ocelli present ; elytra with mar- 

 gins broadly flattened, the venation as in fig. 2 ; 7,; elytra with a 

 cuneus ; inner wings without a hamus, the apical vein with apex

 ing of it is by Reuter, 1884 ; McAfee & Malloch, 1924 ; Bergroth, 

 1925. One genus, represented by a single species, occurs in 

 our territory.
