c?. Slender and narrow. Head with palpi and clypeus white or latter 

 white-marked, and discreted, deeply emarginate laterally and centrally 

 sub-dentate ; epistoma not prominent. Antennae slender and filiform. 

 Thorax cylindrical ; metathorax finely alutaceous, with basal transverse 

 costa alone distinct, the apical one and the apophyses wanting. Scutellum 

 with an apical dot or transverse line white. Abdomen half narrower than 

 thorax, cylindrical, basal segment sub-linear, hardly explanate, sub-claviform, 

 with no tubercles ; post-petiole slightly explanate ; apical margins of the 

 first three segments castaneous, the seventh apically white. Legs elongate, 

 slender ; either with coxae black, anterior trochanters white-marked, 

 anterior femora red with their bases and two longitudinal lines black, hind 

 ones black, tibiae stramineous with hind ones centrally ferrugineous and 

 the black hind tarsi centrally white ; or black, with anterior femora apically 

 stramineous, anterior tibiae testaceous and externally infuscate, and the 

 black hind tibiae centrally, together with apex of the metatarsus, white. 

 Wings with radix stramineous, tegulae entirely or partly white ; areolet 

 quadrate or sub-pentagonal, and nervelet wanting. Length, 9-12 mm. 



Thomson says this little known species certainly belongs to the present 

 genus. Schmiedeknecht differentiates it from all other Hoplocrypti by : — 

 Areolet emitting recurrent nervure evidently before the centre ; face 

 entirely black, only clypeus white ; apex of scutellum and hind tarsi white ; 

 abdomen and legs mainly black. 



9 . Head black ; epistoma not prominent. Antennae with joints seven 

 to eleven laterally white. Thorax immaculate ; metathorax with the basal 

 transverse costa entire, slightly curved throughout and some distance from 

 the base, the apical indistinct and low on declivity, rendering the petiolar 

 area short ; basal area basally convergent ; apophyses small and acute,
