THE HETEROPTERA OF INDO-CHINA. 41 
membrane pale fuscous; body beneath and legs ochraceous, finely 
darkly punctate, tibiz more ochraceous and less punctate; rostrum 
about reaching posterior coxie, its apex black; antennw sanguineous 
second joint very much longer than third, remainder mutilated. 
Long, 12 mm.

This species, which I previously placed as a var. of 7’. latipes, 
Dall., is also probably the J’. ferruginescens, Bredd. 
Hoplistodera tonkinensis, sp. n. 
Ochraceous, sometimes distinctly darker in hue on basal areas of 
pronotum and scutellum; head above somewhat coarsely punctate, 
the central lobe distinctly prominent; antennze ochraceous, second 
and third joints shortest; pronotum coarsely punctate, the lateral 
angles produced in robust subacute spines, their apices slightly 
reflexed backwardly, and with a notched tubercle beneath at about 
half their length; scutellum with about basal half coarsely, sparingly, 
and the apical half more thickly and finely punctate ; corium coarsely 
and irregularly punctate ; body beneath and legs a little more darkly 
ochraceous ; rostrum extending a little beyond posterior coxe. 
Long, 64-74 mm. ; breadth between pronotal angles, 7-74 mm. 
Tonkin, Chapa; Haut-Mékong, Tong Lap. 
Allied to H. incisa, Dist. from British India, but a much 
narrower species, especially in the breadth between the pronotal 
angles; the third and fourth joints of the antenne much 
shorter, etc. 
Hoplistodera scutello-maculata, sp. n. 
Head, pronotum and scutellum brownish ochraceous or pale 
castaneous, anterior area of head more or less mottled with obscure 
ochraceous, central lobe usually more or less piceous; pronotum 
coarsely darkly punctate, its anterior area with luteous waved corru- 
gations, and a transverse piceous spot on each side before anterior 
margin ; scutellum with distinct luteous reticulate fascie, thus giving 
the ground-colour a maculate appearance, three luteous spots on 
basal margin, and the whole surface more or less somewhat finely 
distinctly punctate; corium more or less coarsely punctate; con- 
nexivum dull ochraceous, with pale castaneous segmental maculations ; 
body beneath pale castaneous, the legs stramineous ; antennx pale 
brownish, the basal areas of the joints much paler in hue, third joint 
shortest, second and fourth subequal in length, apical joint longest ; 
lateral pronotal angles strongly and robustly produced, their apices 
somewhat acute. 
Long, 63-7 mm. ; breadth between pronotal angles, 6}—7 mm.
