xiu,D,2 Bergroth: Philippine Heteroptera, I 49 



interhumeral line to a little beyond middle, then almost horizon- 

 tal, a little broader than long, at apex little more than half the 

 humeral width, the lateral angles armed with a tooth or short 

 spine, the straight posterolateral margins forming an obtuse 

 angle with the truncate basal margin. Scutellum longer than 

 broad, acute at apex. Elytra a little shorter than abdomen, 

 commissure of clavus a little shorter than scutellum, apical 

 margin of corium broadly and gently rounded toward the inner 

 apical angle, the outer apical part moderately produced, reach- 

 ing somewhat beyond middle of membrane. Mesosternum 

 longitudinally grooved in the middle. Abdomen in the male 

 with the last dorsal segment roundly produced backward and 

 with a sinuousity between the projecting part and the last con- 

 nexival segment, the apical angle of which is obtuse; in the 

 female with the last dorsal segment broadly and slightly sinuate 

 posteriorly, apical angle of last connexival segment produced, 

 subacute at apex; spiracles placed much nearer to the basal 

 than to the apical margin; sixth female ventral segment with- 

 out a basal plica, but with a percurrent median fissure, the 

 apical margin trisinuate, the median sinuosity rather deep and 

 subacutely angular, the lateral ones broad and shallow ; the two 

 female dorsal genital segments broadly and slightly sinuate at 

 apex. Legs moderately short, femora unarmed, the front pair, 

 when stretched forward, passing apex of head by less then 

 half the length, the hind pair about reaching middle of fifth 

 ventral segment, all tibiae sulcated above, first joint of hind 

 tarsi somewhat longer than the other two together. 



A rather isolated genus coming nearest to Mutusca Stal; but 

 abundantly distinct by the much broader and more robust body ; 

 quite differently constructed juga, antennae, bucculse, pronotum, 

 and sixth female ventral segment; more separated and more 

 forwardly placed ocelli; longer rostrum and legs; less pro- 

 duced outer apical part of corium; different position of the 

 spiracles; sulcated tibiae; and shorter metatarsus of hind legs. 



Type of the genus, Dicorymhus nigridens sp. nov. 



Dicorymbus nigridens sp. nov. 



Lurid ochraceous, rather coarsely and densely brown- 

 punctured, median part of mesosternum impunctate with two 

 narrow punctate vittas, the tooth of the humeral angles black, 

 apex of scutellum and a spot at apical margin of corium in the 

 cell near the inner apical angle whitish and impunctate, a spot 

 at apical angles of connexival segments (much larger on the 

 last segment) , two spots at base and one at apical angles of first 

 female dorsal genital segment (sometimes confluent), and
