Stal, and for the present I prefer to place it as the northern 

 form of his species. Two of my specimens were taken at 

 Tucson, Arizona, by Prof. E. B. Wilson, two were captured in 

 Yuma Co., Arizona, by Prof. Snow in June, and one was taken 

 at Congress Junction, Arizona, in July by Prof. Snow. Prof. 

 Wilson has also sent me two examples of a smaller paler species 

 from La Jolla, California, that I place as Stal's pallidicornis. 

 They answer to his description in everything except that the 

 head is almost entirely black and the rostrum is longer, attain- 

 ing the apex of the fifth segment. This species has the apical 

 notch of the male genital segment deeper and narrower than 

 infemorata. 



Narnia wilsoni n. sp. 



Deep piceous black ; lower surface of the head, antennae, base of the 

 rostrum, bucculse and legs bright ferruginous ; abdomen testaceous ; ex- 

 treme tip of the scutellurn and a transverse linear band on the middle of 

 the corium, not attaining the costa, white. Antennae shorter and thicker 

 than in any of our other described species, the basal joint scarcely sur- 

 passing the apex of the head. Pronotum and scutellum closely punctate. 

 Elytra deep velvety black, with the costa slenderly pale ; membrane fus- 

 cous black, the nervures undulating and here and there anastomosing. 

 Hind legs piceous-black, becoming ferruginous on the base and outer 

 side of the femora and knees ; simple apex of the tibiae and the tarsi 

 bright ferruginous, tibial dilatation about as in snout, almost linear with- 

 out, within about twice wider, with a few strong teeth from near the base 

 to the apex of the tibia, and showing no indication of the white mark 

 found in our other species. Rostrum short, scarcely surpassing the base 

 of the fourth ventral segment. Venter covered with a white mealy pubes- 

 cence which omits the rather broad median sulcus. Length 12 mm. 



Described from two female examples taken at La Jolla, 

 California, in August, by Prof. E. B. Wilson. 



This is a very distinct and striking species. With snoici it 

 forms a group for which I would suggest the subgeneric name 

 of Xcrocoris, which with the study of more extensive material 

 may be raised to generic value. It may be characterized by a 

 broader form, wider connexivum, more strong!}' depressed pos- 

 terior margin of the prouotum, a proportionately shorter head, 

 shorter and stouter antennae, a shorter rostrum and a different 

 vestiture. In both these species the disk of the pronotmn is 

 flatter with a distinct median carina which is scarcely indicated
