DINOMACHUS. 39 



pale ochraceous ; antennae with the extreme apices of the second 

 and third joints and the apical joint (excluding base) more or less 

 piceous ; tibiae biannulated with pale brownish, ' apices of tarsi 

 piceous, posterior femora with a fuscous spot on upper surface a 

 little beyond middle ; antennae with the second joint slightly 

 longer than the third, fourth joint slightly or scarcely longer than 

 the second ; posterior lobe of pronotum somewhat coarsely 

 punctate ; scutelluin finely obscurely punctate on basal, much more 

 strongly punctate on apical area ; clavus longitudinally punctate, 

 corium linearly and more sparingly punctate. 



Length 5 millim. 



Hob. Calcutta. 



Differs from S. validus, Dist., by the differently coloured head 

 and pronotum and the much less or scarcely pilose character of 

 the same. 



Genus DINOMACHUS. (Vol. II, p. 37.) 



2815. Dinomachus rhacinus, Dist. Ann. Soc. Ent. Belg. 1, p. 410 

 (1906). 



Ochraceous, thickly finely darkly punctate ; pronotum with the 

 extreme lateral margins piceous, a broken macular black basal 

 fascia, and with a central pale line to posterior lobe ; scutellum 

 piceous, with a central pale line on apical area ; corium with two 

 small spots on disk, a transverse spot before apex, and the apical 

 angle black ; membrane bronzy ; connexivum spotted with piceous ; 

 body beneath piceous, disk of abdomen and legs ochraceous ; 

 tibise, tarsi, and apices of femora annulated with castaneous; 

 rostrum reaching the intermediate coxae, basal joint scarcely 

 passing base of head ; antennas pale castaneous, base and subapical 

 annulation to first joint, subbasal annulation and apex to second 

 joint, and apex of third joint ochraceous, second joint longest; 

 head broad, central lobe a little prominent at apex, thickly finely 

 pilose, obscurely thickly punctate; pronotum with the anterior 

 lobe moderately globose, its lateral margins convex, distinctly 

 narrower than posterior lobe ; scutellum as long as broad, largely 

 irregularly excavate at each lateral angle, and obliquely depressed 

 on each side at apical area, thickly finely punctate ; corium more 

 sparsely and finely punctate, the punctures arranged longi- 

 tudinally.

 Ind. Mus.}. Ceylon ; Wellawaya (E. E. Green). 



This and the following species D. nitidiusculus are distinct from 

 D. sikhimensis (vol. ii, p. 38) by the narrower anterior lobe of the 

 pronotum, thus agreeing more with the typical South African 

 species D. marshalli, Dist.
