long, article I small and narrow, article 11 attenuated at its base, at least 

 twice as long as article 111, article 1\^ very small, hidden in a pit near the 

 extremit}' and on the ventral surface of cU'ticle 111 with numerous terminal 

 hairs ; marginal hairs on articles 11 and 111. Legs hrownish, of medium 

 length, thick and swollen, hairs rare and sJiort ; coxae rather long, a single 

 short spine on the postero-median margin of each ; tarsi at least three 

 times as long as wide, a large hosse near the extremity and on the dorsal 

 side of each, two consecutive spurs, the termiiial larger, on coxae 11, 111, 

 and 1\' ; cai'uncle short, scarcely reaching a c[uarter of the length of the 

 claws. 



Feiiialc. — Bodij thick, wider Ijehind than in front, widely rounded 

 at the two extremities ; colour generally reddish l)rown ; reaching a 

 length of T mm. and a width of 5 mm. or more. Shield heart shaped,, 

 as long as wide, contour a little sinuous, posterior angle rather narrow, 

 well emarginated in front, glabrous ; cervical grooves wide, deep, and 

 short, prolonged backward by a superficial groove, which is concave out- 

 ward ; punctuations, fine numerous, three metallic green spots as 

 follows : — One in each cervical angle, bordering on the cervical grooves, 

 and one on the }!Oste]'ior angle ; sometimes the spots are very faint in 

 colour, but always more or less sharply defined. Dorsal surface with 

 four anterior grooves, short and symmetrical, followed by three shorter 

 grooves, and finally by three or tive grooves, which are long and close 

 to the median line ; hairs very short, scattered ; punctuafions fine, 

 scattered, porose areas just posterior of shield, widely separated. Ventral 

 surface with colour, punctuations, and hair as on dorsal surface : sexual 

 orifice narrow, a little in front of the level of coxae 11 ; sexual grooves 

 very widely separated t)ehind ; anus near the posterior quarter of the length 

 of the body ; anal groove semi-circular, opening forward ; ano-marginal 

 groove long, a short groove on each side of it, in partly engorged females ; 

 stigmatic plates large, triangular, transverse. Rostrum {XIV, g) rather 

 large, narrow, nearly as long as shield ; base with dorsal surface nearly 

 as long as wide, rounded on the sides ; porose areas large, deep, slightly 

 elongate longitudinally ; digit of mandibles with inner apophysis strong, 

 conical, base thick, point recurved, with the transverse process near the 

 tip, outer apophysis with three teeth, strong, largest near the base ; 

 hy])ostome with (lentieles at tip, then six to seven hirge teeth in a row,, 

 crenulations to l)ase (XIV, d) ; palpi as in male. Legs as in male ; coxae 

 bearing one spine on their postero-median margin (XV, c) ; tarsi as in 

 male, except that only on tarsus 1 is the bosse near its extremity very 

 prominent (XIV, i). 



Nymph. — Body flattened, wider behijid, broadly rounded at both 

 extremities, almost orbicular ; colour dark reddish l)rown ; length 2.3 mm. 

 (without rostrum), width 2 mm. SJiieJd (.Y/T\ e) dark chestnut brown, 

 postero-central area and posterior edge of t le cervical emargination a little 

 lighter ; heart shaped ; as wide as loQg ; widely rounded behind ; 

 postero-lateral edges concave ; antero-lateral edges convex ; punctua- 

 tions few but large, and of equal size ; cervical grooves deep at 

 first, then shallow and diverging toward the margins ; cervical emargina- 

 tion shallow. Dorsal surface with a few large punctuations and a few 

 whitish short hairs; four short anterior ; grooves, followed by a set of 

 two short lateral grooves on each side, ()ne anterior of the other, and 

 these in turn by three long grooves, one ' median and two lateral, which 

 diverge posteriorly, with the addition of fa short groove on each side of
