Hah. Gold Coast, Aburi {W. R. Fatterson, 1912-13).

aS'. cliiriquensis Fowl.:=/S'. nigrolineatus Muir. 



Syntames delicatus, var. chiriquensis Fowl. o^j. cit. p. 139, t. 13, 

 fig. 22 (1905). 



This insect is specifically distinct from S. delicatus Fowl. (fig. 21), 

 under which it was placed as a variety. 



(S . Medio-ventral process of the pygofer small, angular, lateral margins 

 entire, slightly arcuate ; anal segment long, narrow, tubular to anus near apex, 

 apex beyond the anus broadened, apex roundly emarginate, each lateral corner 

 forming a curved broad spine ; genital styles large, reaching apex of anal seg- 

 ment, ventral edge straight with a narrow, long, flat process about the middle, 

 dorsal edge produced subangularly to middle, apex of projection extended into 

 a flat process longer than broad and turned inw^ard, slightly basad of this the 

 edge is produced into a more angular process, apex acute, curved inward. 



The male here described is from Bartica, British Gruiana. S. deli- 

 catus Fowl, has the genital styles broader ; the dorsal edge is produced 

 near base, then straight and entire. 



S. siiffiavits Muir. 



The male genital armature of this species differs from that of S. chinque7isis 

 in having the genital styles sublanceolate and curved, the ventral edge is 

 slightly produced and turned inward, Avith a spine-like projection near the 

 base, the dorsal edge is roundly produced in the middle, with a small projec- 

 tion and an emargination near the base, apex pointed and turned slightly
