280 PROCEEDINGS OF THE ACADEMY OF [April, 



describing a species of Chiropacha, applied the name modesia to it,* 

 and later he used it under Tarachodei. The maintenance of two 

 identical names in the same genus not being permitted, I have 

 dedicated this species to its original describer, 

 Taracliodes sp. 



One immature specimen ; Gagap, near Milmil, northern Somali- 

 land, July 30, 1894. 



This specimen is too immature to make any definite statement 



regarding its specific affinities.

Type, one specimen, near the Darde river, Raia Wacheli, eastern 

 Gallaland, September 1, 1894. 



This species differs from C. cmomala Saussure in the much greater 

 size, in the non-mamillate eyes, the smaller and weaker forelimbs, 

 and various other details. 



Form slender. Head elongate with a broad, low median ridge, 

 vertex not at all prominent, ocelli small; eyes subelliptical; an- 

 tennae filiform. Pronotum rather elongate, slightly broader pos- 

 teriorly than antei'iorly, the length being more than six times the 

 greatest width; lateral margins almost straight, slightly constricted 

 anterior to the insertion of the coxse, finel}' tuljerculate; anterior 

 and posterior margins arcuate, the latter flattened centrally with 

 an obscure eraargination ; the whole surface finely tuberculate. 

 Tegmina abbreviate, semi-hyaline, rather coriaceous at the base. 

 Abdomen depressed, narrow, the lateral margins almost straight, 

 the basal and median segments one and a half times as long as wide, 

 terminal segments short, the posterior margins with a median 

 rounded lobe. Supraanal plate triangular, moderately produced, 

 the apex truncate, subemargiuate and obscurely carinate centrally,
