protected by one single scaly sliield, provided with bairs, wbicb 

 are arrauged exactly like tbose on tbe dorsal side of tbe nympba. 

 Only tbe marginal bairs are stronger. Tbe ventral side (Fig. 41) 

 shows us two sbields. One of them I may call a scaly sterni-geniti- 

 ventral and tbe otber an anal one. Tbe foriner occupies tbe space 

 between the coxae and nearly the forernost half of the venter, 

 and shows the genital aperture in front and 12 little hairs. Tbe 

 anal shield like tbat of the nymph. The peritrema runs forward, 

 passing the coxa 3. The cf are recognizable by tbeir 8 or 10 

 bairs on the posterior margin of the abdomen. 



Female. Length 670—790 p. when fasting or scarcely fed, reaching 

 1300^. when well fed. Shield 665^.; first leg 700^., including 

 the coxa. Colour like tbat of tbe nymph. Shape long-oval, scarcely 

 shouldered, witb its top backward when fasting (Fig. 42) ; broad- 

 oval, not shouldered and with its top forward, when well-fed 

 (Fig. 43). The dorsal side is hairy; tbe hairs are short, distinctly 

 curved; tbere is one long scaly dorsal shield, the forernost third 

 of wbich corresponds to tbe nymphal shield ; the hairs on this 

 shield have exactly the same number and places as tbe hairs on 

 the dorsum of the nympba. The hindmost top of this shield 

 corresponds to the posterior dorsal shield of the nympha. The 

 dorsal shield gets a little narrower towards in the middle. 



On the ventral side (Fig. 43) there are tbree shields distinct, 

 vix. 1. a trapezoidal sternal shield, excavated roundly posteriorly, 

 bearing four bairs and having a chitinous marking with a median 

 point forward ; 2. a genital shield corresponding to the geniti-ventral 

 portion of the large ventral shield of the male, distinct posteriorly, 

 indistinct, rounded and longitudinally folded anteriorly; 3. the anal 

 shield, closely resembling those of the nymph and the male, but 

 larger. The peritrema runs forward almost passing the legs 1. 



Of tbe legs of the nymph, the male and tbe female I can observe 

 only tbat the femurs 1 and 2 are provided dorsally witb two 

 bairs, stronger and more spiny than the others, and diverging; 

 and tbat the femurs 3 and 4 and genus 3 and 4 have one similar 

 hair on tbeir fore-side.
