130 TERRESTRIAL FAMILIES OF IIEMIPTERA-IIETEROPTERA 



developed bristles; bucculae well developed; rostrum short reaching Init to the posterior 

 margin of the prosternum; apex of second joint reaching but to the base of the head, the first 

 joint the longest; sides of pronotum slightly explanate, pronotal disc with two large raised 

 circular areas, and an ill-defined longitudinal carina; sutures between thirtl and fourth and 

 Ijetween fourth and fifth abdominal stcrnites almost straight, reaching almost to the con- 

 nexivum where they become fragmented and obscure ; glandular patches on fourth sternite 

 apparently absent; abdominal spiracles all ventral save that of the fourth segment which 

 is situated dorsally on the connexivuni ; anterior femora incrassated but unarmed, well-devel- 

 oped tarsal aroliae absent. Genotype : — D. deterrana sj). n. 



7. Dolmacoris deterrana sp. n. 



Color. Dull greyish-yellow, somewhat suffused with orange, eyes and ocelli reddish 

 brown, punctures and bases of bristles very dark brown or black, posterior smooth part of 

 vertex and central carina of pronotum slightly paler, elytra with two large tubercles reddish, 

 abdomen dorsally obscurely mottled with brown, anterior margin of connexival portion of 

 tergites and a small transverse stripe on the same on tcrgites five, six, and seven, black; 

 abdomen ventrally black mottled with greyish-}-ell<)w laterally, antennae and legs greyish- 

 yellow with large black spots at the bristle bases, fourth antennal joint uniformly blackish 

 brown, femora with heavy black puncturation, apices of tarsi somewhat darkened. 



Head. Dorsal surface, save for two areas immediately around the ocelli, a median 

 area nn the extreme jjostcrior i)art of the vertex and the anterior three-quarters of the 

 \entral surface lateral to the bucculae, coarsely :im\ irregularly ])uncturc(l: anterior and 

 postero-central part of head dorsally with conspicuous sparsely set bristles, two being set 

 on the labrum; width of head with eyes greater than length seen from above (0.98, 0.76 

 mm.) ; clypeus very distinctly separated l)y furrows from the jugae; antenniferous tubercles 

 well developed, downwardly directed in lateral view (Plate IX, fig. 3), and giving the pre- 

 ocular part of the head a very slightly constricted outline in front of the eyes; eyes very 

 large and subpedunculate, situated behind the middle of the head; bucculae well developed 

 and elevated, somewhat divergent, reaching practically to the posterior margin of the head, 

 suddenly and obliquely lowered in the posterior eighth of the latter; rostrum short reaching 

 but to the posterior margin of the ])rosternutn, the first joint the longest, about one and 

 one-half times as long as the second, which reaches to about the posterior margin of the 

 head, the third subequal to the second and slightly longer than the fourth (Plate IX, fig. 

 5). Antennae rather short, basal joint cylindrical, reaching alx)ut to the apex of the head 

 and stouter than the others, three basal joints and base of the fourth with strong bristles 

 which are a little longer than the diameter of the second joint, the latter joint twice as long 

 as the first, and just under twice as long as the third which is just under half the length 

 of the fourth (0.25, 0.47, 0.22, 0.45 mm.V 



Thorax. Pronotum (Plate IX, fig. 1) subequal in length to the head and one and 

 two-thirds times as wide as long (1.18, 0.72 mm.), anteriorly narrower and posteriorly 

 wider than the head, subtrapeziform, with all sides slightly and widely emarginate, anteri- 

 orly with an ill-defined collar behind which the lateral margins are slightly explanate, forming 

 a cariniform expansion which is impunctate above and bears a row of five short bristles
