THE HETEROPTERA OF INDO-CHINA. 147 



Hamatoloecha ohscurata, sp. n. 



Pale brownish-ochraceous ; anterior pronotal lobe, apical area of- 

 hemelytra, and the sternum darker in hue ; antenncE longly hirsute, 

 first joint ochraceous, remaining joints fuscous, second joint dis- 

 tinctly longer than first ; longitudinal incisure to pronotum slender 

 and acute, it and the sublateral incisures to the posterior lobe some- 

 what obscurely punctate ; scutellum transverse, the apical angles 

 widely separated ; anterior femora with a single prominent spine 

 beneath. A species also to be recognised by its somewhat flattened 

 structure. 



Long, 12 mm. 



Habitat. — Tonkin ; Chapa. 



Hamatoloecha chapana, sp. n. 



Closely allied to the preceding species, but darker and more 

 piceous in hue ; antennae entirely piceous, basal joint not paler but 

 concolorous ; anterior femora with two prominenib spines beneath. 



Long, 12 mm. 



Habitat. — Tonkin ; Chapa. 



Hcernatoloecha nigrornhra, sp. n. 



Head, antennae, legs, rostrum, body beneath, scutellum, and 

 membrane of the hemelytra, black ; connexivum, anterior lobe of 

 the pronotum, the clavus and claval margin dull pale olivaceous ; 

 posterior pronotal lobe and the corium testaceous ; antennae longly 

 hirsute, second joint subequal in length to first ; pronotal incisures 

 narrow ; scutellum transverse, the apical angles widely separated. 



Long, 14 mm. 



Habitat. — Suang Prabang ; Pak Tha, Ban Thiou. 



Neozirta, gen. nov. 



Antennae four-jointed; head subequal in length to first joint of 

 antennge, behind eyes constricted, between and before eyes laterally 

 and centrally longitudinally ridged ; collar short ; rostrum with the 

 first and second joints subequal in length ; pronotum about as long as 

 broad at base, with the anterior lobe much narrower than the 

 posterior lobe, strongly longitudinally excavated, the central excava- 

 tion extending through the anterior lobe, the other two excavations 

 confined to the lateral areas of the posterior lobe ; scutellum broad, 

 a, little broader at base than long, or including the apical angles 

 about as broad as long ; other characters generally as in Zirta. 



Allied to the neotropical genus Zirta, Stal, but differing by 

 the narrower and shorter anterior lobe of the pronotum ; the 

 pronotum nearly or about as long as broad at base, not distinctly 

 shorter as in Zirta ; scutellum shorter and relatively broader.
