Tityus Simonsij sp. n. 



Diflfering from T. ecuadorensis typicus, which also occurs at 

 Loja, in having the upperside of the trunk a uniform blackish 

 brown, without yellow bands, the legs not variegated, but 

 yellow at the base, and becoming lightly infuscate upon the 

 femora and patella?, and the whole hand blackish or brownish 

 red, the finger-tips only being yellow ; tail with segments 1-3 

 pale above, black along the middle line below and posteriorly 

 on each side, much as in T. ecuadorensis; fourth and fifth 

 segments and vesicle blackish ; sterna uniformly pale. 



Trunk granular and crested above, as in T. ecuadorensis: 

 sterna of abdomen coriaceous, the first and second without 

 large punctures ; fourth and fifth finely granular, the former 

 with a pair of weak keels, the latter with four granular keels, 

 the external abbreviated posteriorly. 



Tail granular and crested practically as in T. ecuadorensis ; 

 vesicle wider than brachium, furnished with a spine which is 

 much smaller and closer to the base of the aculeus than in 

 T. ecuadorensis, much resembling, in fact, the spine of T. in- 

 siqnis or T. obtusus.
