TERRESTRIAL FAMILIES OF HEMIPTERA-IIETEROPTERA 131 



just within the margin; disc with a few short bristles and two large circular raised areas 

 with central depressions, behind which are a pair of ill-defined tubercles, between each 

 raised area and continued behind between the tubercles a very ill-defined longitudinal carina. 

 Propleuron punctured, its posterior margin distally bent back towards the posterior angle of 

 the prothorax. Prosternum with a wide well-defined longitudinal rostral depression, the 

 sides of which are raised posteriorly against the articulation of the anterior coxae, anterior 

 part of prosternum forming a distinct collar which is coarsely punctured. Apertures of 

 metathoracic scent-glands small and set a little obliquely, their margins hardly elevated. Legs 

 with numerous well-developed bristles throughout. Anterior coxa with an inwardly project- 

 ing lamelliform tooth; anterior femur moderately incrassated, its maximum diameter being 

 about twice that of the femora of the other legs, subequal in length to the anterior tibia; 

 the latter slightly expanded apically, twice as long as the tarsus (0.84, 0.90 mm.), first tarsal 

 joint twice the second which is about two-thirds the length of the third and equal in length 

 to the claws (0.16, 0.09, 0.13, 0.09 mm.). Intermediate coxa acutely angulate interno- 

 posteriorly but not produced into a definite tooth, femur subequal in length to tibia; the 

 latter twice as long as the tarsi (0.84, 0.44 mm.), first tarsal joint three times as long as 

 second, second about two-thirds as long as third and equal in length to the claws (0.18, 0.09, 

 0.16, 0.07 mm.). Posterior coxa obtusely angulate interno-posteriorly, femur very slightly 

 shorter than tibia; the latter twice as long as the tarsus (1.24, 0.62 mm.), first tarsal joint 

 equal in length to the others together, third one and two-thirds as long as second, claws a 

 little shorter than the latter (0.29, 0.11, 0.18, 0.07 mm.). No aroliae can l)e made out on 

 any tarsi. 



Elytra (brachypterous) covering the proximal half of the abdomen ; widely expanded 

 in their proximal quarter so as to cover the base of the connexivum, in their distal three- 

 fourths slightly narrowed exposing the connexivum; posteriorly obliquely truncate; claval 

 vein (cubitus) well developed and tuberculate, inner corial vein {media) more or less obsolete, 

 represented by a feebly developed carina bearing a single minute tutercle; subcosta -}- 

 radius well developed, dividing behind the middle of the elytra to form two large tubercles, 

 with the inner, more anterior, one of which, the inner corial vein appears to fuse, three longi- 

 tudinal tuberculate carinae behind the tubercles apparently re])resent the subcosta, radius and 

 media freely approaching the posterior margin of the elytron. 



Abdomen. Broad, depressed centrally, coarsely and irregularly punctate, sutures between 

 sternites two and three, three and four, and four and five, almost straight, very slightly 

 turned forward at their distal ends, especially in the case of that between three and four, 

 the latter antl that between four and five not quite reaching the connexivum and irregularly 

 fragnnented at the ends; all spiracles, small, those of the fourth segment dorsal, the rest 

 ventral (Plate IX, fig. 2) ; opaque glandular patches not developed on the fourth or any 

 other sternite ; fourth and fifth tergites with their posterior margins produced backwards as 

 obtuse angle, each angle enclosing a well-marked tubercle, the two tubercles sul^equal in size 

 and rugose. 



S Seventh abdominal tergite evenly rounded behind, posterior margin of sternite 

 straight (Plate IX, fig. 8) ; genitalia as in most Aphaninae, with a long spiral vesica (cf. 

 Singh-Pruthi 1925), ba.sal plates moderately large (Plate IX, fig. 6), parameres dilated 

 sub-hasally, narrower and slightly bent apically (Plate IX, fig. 7).
