Velidia, gen. nov. 



Aspect of a robust Metacantlms, but a genuine Nabid, with 

 certain elements of structure, such as a blunt vertical head and 

 deep pronotum, quite out of keeping with the ordinary members 

 of this group. Head short, with a polished swollen base, which is 

 separated from the space in front of the eyes by a transverse groove ; 

 the eyes oval, vertical, projecting but little beyond the occipital 

 swelling ; front short, but slightly convex. Rostrum conical at base, 

 beyond this slender and reaching upon the posterior coxae ; the tylus 

 vertical, narrow,tapering, the cheeks also narrow. Antennae slender, 

 the basal joint a little longer than the head; the second joint more 

 slender, nearly twice as long as the basal one ; the third equally 

 slender, a little longer than the second ; the fourth shorter than 

 the second. Pronotum short, blunt, subtrapezoidal, having a 

 recurved collum which caps the base of the head ; the anterior lobe 

 almost entirely occupied by the smooth, swollen, transverse callo- 

 sities, the lateral margins carinated along the upward curve of the 

 callosities ; the posterior lobe high, sloping forwards, almost flat, a 

 little wider than long, with the posterior border detlexed and the 

 edge sinuated and re flexed ; the pleural flaps wide, almost abruptly 

 detlexed, forming a cap, the edges widely reflexed. Scutellum sub- 

 lunate, very short, almost covered by the pronotum, with the apex 

 acuminate. Legs of median length, the posterior femora a little 

 clavate at tip ; the anterior pair thickest, tapering at both ends
