prominent and centrally longitudinally ridged, grcyislily 

 transversely striate on each lateral area ; rostrum about

Triecphora Johanna, sp. n. 



Head, pronotum, scutellum, body beneath, and legs pale 

 castaneous brown, abdomen above brownish ochraceous, apex 

 of scutellum pale ochraceous; tegmina black, crossed by two 

 transverse greyish fasciae, the broadest near base, the nar- 

 rower at about one-third before apex ; Mings pale fuliginous; 

 head foveately impressed on each lateral area at inner side 

 of eyes ; pronotum very finely wrinkled and punctate, 

 roundly subfoveately impressed on each side near anterior 

 margin and behind eyes ; face angulate and very strongly 

 centrally longitudinally ridged ; posterior femora with one 

 strong spine at about one-third before apex. 



Long., excl. tegm., 10 mm. ; exp. tegm. 24 mm. 



Hab. Comoro Islands; Johanna (Bewsher, Brit. Mus.). 



This is the specimen referred to by Dr. Butler (Ann. & 

 Mag. Nat. Hist. (5) iv. p. 41, 1879) as an apparently new 

 species of Phymatostetha, contained in a small collection of 

 Arachnida from the island of Johanna. It has been reset, 

 and is now in perfect condition. 



Triecphora karschi, sp. n. 



Tomasjm binotata, Karsch (nee Disk), Stett. ent. Zeit. 1894, p 114, 

 t. ii. fig. 8. 



Karsch probably intended to ascribe this species to my 

 T. conspicua rather than to T. binotata, with which it has 

 little in common. From T. conspicua it differs by having 

 the abdomen above black, not sanguineous or dull reddish ; 

 the legs black ; tegmina with a small red spot nearer to apex 

 than the much larger spot in conspicua. Structurally it is 

 distinct by the formation of the face, which is not " robustly 

 and convexly tumid " as in conspicua, but smaller, com- 

 pressed, and with a very distinct central longitudinal ridge 

 extending about halfway from base.
