The body of the adult female is convex on the dorsal aspect and flat 

 on the ventral. It is elongate elliptical in outline with the cephalic end 

 bluntly rounded and the caudal end bluntly pointed. The caudal end 

 of the body is not inflated and the cephalic and lateral margins are not 

 provided with a keel. The segments are well defined. The antennae 

 are prominent, consisting of eleven segments, and are articulated to the 

 ventral aspect of the head near each lateral margin. The eyes are not 

 described. The mouth-parts, rostrum and rostralis, are always present, 

 the rostrum consists of three distinct segments. The legs are present. 

 They are subequal in length and normal in form. The profemora are 

 never enlarged and the prothoracic legs are never fitted for digging. 

 The trochanto-femoral and tibio-tarsal sutures of all the legs are proba- 

 bly distinct. The thoracic and abdominal spiracles are not definitely 

 described and not figured. The stigmatic clefts, spinae, and canellae are 

 wanting. The abdomen is about as long as the head and thorax togeth- 

 er. It is convex on the dorsal aspect, never depressed. The lateral mar- 

 gins converge slightly caudad and the caudal end is bluntly pointed. All 

 the segments are fully exposed and similar in appearance with distinct 

 coriae between them, none are retracted to form a marsupium. The 

 abdomen is never provided with an anal cleft and opercula or anal lobes 

 and anal setae. The anal ring is always distinct and provided with six 

 prominent anal ring setae. The caudal abdominal segment is never 

 short and narrow, extending beyond the other segments. The body is 

 provided with cerores, none of which are octacerores or pilacerores and 

 is never provided with ceratubae. The body is never enclosed in a res- 

 inous cell with three adjacent openings or covered by a scale with or 

 without exuviae, but is covered with white mealy wax among which is 

 mixed some curling cottony threads of wax. The rectum is never pro- 

 vided with a long glassy tube of wax or with a chitinized rectal tube 

 bearing one or more rings of anacerores. The body is never naked and 

 gall-like in form. 



The female nymphs of all stages, so far as known, are provided with 

 a rostrum and rostralis. The three pairs of legs are present in all 

 nymphal stages and are similar in form. The profemora are never 

 greatly enlarged and the prothoracic legs are never fitted for digging. 

 The body is never provided with an anal cleft and opercula, anal lobes 

 and anal setae, octacerores, pilacerores, or ceratubae. The anal ring 

 is distinct and bears six anal ring setae. The caudal end of the rectum 

 is not chitinized, forming a rectal tube provided with one or more rings
