Distnhution. Palaearctic, Ethiopian, and Oriental Regions. 



" Head : crown narrow, not produced in front as in Anisops ; 

 antennae four-jointed, first joint short, second large, somewhat 

 oval, flattened on the sides, third minute, fourth elongate, as long 

 as the second and third together, narrow, somewhat lunate ; eyes 

 A^ery large, curved with tlie head, viewed from above somewhat 

 rhomboidal, Avith rounded angles, touching each other at the inner 

 basal angle, from the side triangular, upper and under margin 

 convex, apex rounded, posterior margin E-sbaped ; rostrum stout, 

 four-jointed, reaching to betAveen the first pair of coxse, first joint 

 covered by the triangular labrum ; pronotum short, posterior 

 margin slightly concave across the scutellum ; scutellum long, tri- 

 angular, pointed, sides concave ; elytra convex, without a clavus or 

 membrane; embolium narrow, nearly as long as tlie corium; wings 

 none ; sternum long, sides densely clothed with fine long appressed 

 hairs ; presternum short ; mesosternum transverse, anterior margin 

 in the middle with a callus, sides reflexed, xyphus rounded, apex 

 considerably depressed ; metasternum long, posterior margin in 

 the middle triangular; legs: first and second pairs short, third 

 very long ; tibiae : first pair at the apex with two short spines, 

 lower margin with a few long, semi-erect, stout spinous hairs; tai'si : 

 first and second pairs with the first joint twice as long as the 

 second ; claws : two on the first and second pairs subequal, on the 

 third minute; thighs, tibiae and tarsi of the third pair of legs of 

 almost equal length." (Scott.) 



" Very closely allied to the genus Anisops, from which it differs 

 in not having the crown elongated nor the eyes separate, and in 

 the not decidedly different proportions of the various parts of the 

 hind legs." (Scott.) 



I have given Scott's description of this genus under the name 

 of Antipalocoris because it is fuller and more precise than that 

 of Stal.
