joints longly pilose ; anterior lobe of pronotum with six long 
spines on discal area, two short spines near anterior margin, 
the anterior angles obtusely spinous, and a short spine near 
middle of lateral margins ; posterior pronotal lobe with six 
spines, three on each lateral area, the lateral angles also 
strongly spinous ; scutellum with long and robustly curved 
spines—one apical and one on each lateral margin; corium 
with six moderately short spines—four lateral and two sub- 
lateral; connexivum with some spines at the segmental 
angles. 
Long. 38 mm. 
Hab. W. Africa; Coomassie (VV. Samwell). 
Allied to P, ducalis, Westw., but differing by the much 
less spinous anterior marginal area of the pronotum; red 
aunulations to the femora also shorter. 
Pysttala incognita, sp. n. 
In general colour and markings allied to the preceding 
species, but the anterior lobe of pronotum with only six 
spines, three on each lateral area, and the posterior lobe with 
tour short spines, the posterior lateral angles longly spinous ; 
corium with four sublateral and two inner spines. 
Long. 37 mm. 
Hub. West Africa (no precise locality). 
Pysttala johnstoni, sp. n. 
Head, pronotum, corium, body beneath, and legs black ;

large marginal spots to the abdomen ochraceous ; antennze 
with the first jomt black, not quite reaching base of head, 
second joint ferruginous, about three times as long as first, 
moderately pilose ; anterior lobe of pronotum with six long 
spines on discal area, the anterior angles obtusely spinous, 
posterior pronotal lobe with four spines, two on each lateral 
area, the lateral angles also strongly spinous; scutellum with 
long and robustly curved spines—one apical and one on each 
lateral margin ; corium with three lateral and five or six 
sublateral spines; connexivum with some spines at the 
segmental angles.
