( Figs. 10–18 , 21–31 , 37–42 , 48–54 ) Length (incl. tegmen): ♂ , 6.7–7.8 mm; ♀ , 9.0–9.2 mm. Coloration and morphology. Body with coloration brown-black. Head in dorsal view with one pair of angulate projections between eyes and apex; frons ( Fig. 15 ) produced to short, compressed, slightly curved horn at base and furnished with many small tubercles; frons and clypeus area convex. Pronotum ( Fig. 13 ) without raised median longitudinal ridge; anterior margin straight. Scutellum ( Figs. 16, 17 ) divided into three parts: anterior part disklike with two pairs of large tubers; middle part elevated with centre slightly hollowed out; region connecting middle and posterior part of scutellum long and light-colored; posterior part lower than middle region, furnished near apex with small conical tubercle. Abdomen ( Fig. 18 ) tergites III-VI with lateral margins weakly expanded into dentations. Male genitalia. ( Figs. 25–31 , 37–42 ) Connective ( Figs. 31 , 40 ) Y-shaped, stem longer than arms. Style about 2.5x connective length. Only terminal half of shaft with interrupted wavy wrinkles; gonopore subapical on ventral surface. Female genitalia. Second valvula ( Figs. 52, 53 ) with toothed distal blade slightly more than half of total length, apparently broadened, dorsal margin with small, somewhat irregular teeth distributed over most of length.

India , 3,500 ft , Oct. 1950 , PSN, ( NCUS ) ; 1♂ , Bangalore , S. India , 3,000ft , 11-X-10 , (IMK). ; 1♂ , Dohnavur , 350m , Tinnevelly Dt. , S. India , 30-IX-38 , ( BMNH ) ; 1♀ , Malabar , S. India , 2,000 feet , Oct. 21 1938 , P. S. Nathan , ( NMNH ) . Etymology. This species epithet was derived by combining scute -, meaning scutellum, with - alba , meaning white. Remarks. This species closely resembles H. paradoxa Stål , but is readily distinguishable by the shape of the pronotum, scutellum and abdomen, and the texture of the aedeagal shaft.
