Head clypeated : rostrum of four joints, inserted towards the 

 base of the head, remote from the source of the labrum ; scutellum 

 very large, covering the entire abdomen ; hemelytra longer than 

 the body, with the apical half inwardly folded ; longitudinal veins 

 of the membrane simple ; tarsi of two joints, the first joint very 

 short. 



The Plataspidinae are absent from the Nearctic and Neo- 

 tropical Eegions, but are found in all other parts of the world ; 

 very sparingly indeed in the Palaearctic Region. They are common 

 in the Ethiopian, and abundant in the Oriental Region. Then, 

 again, they appear more sparingly in the Australian Region, and are 

 probably represented throughout the islands of the Southern Seas. 

 They comprise insects which are, according to present knowledge, 

 of little injury to agriculture, for scarcely any mention is made of 

 them in economic entomological reports, but little is recorded of 

 their habits and life-histories, and our present iuformation largely 

 consists of names and localities.
