It is interesting to know lliat E. arabica has been recorded from 

 Webithal, Ogaden, by Schulthess'; later the same author^ con- 

 siders specimens from Obbia somewhat removed from true arabica.

This rather peculiar species is evidently allied to T. media 

 Schulthess-Schindler^ and T. ccstuans Saussure*, systematically and 

 geographically fitting between the two. From media it differs 

 in the form of the head, which is anteriorly truncate instead of 

 irregularly arcuate, and the presternum which is unifasciate instead 

 of trifasciate ; from (sstuans it differs also in the form of the head, 

 and in the form and size of the joints of the cerci. 



c?. — Size rather large, moderately robust. Head with vertex 

 transverse, subtruncate. Pronotum about twice as long as the 

 greatest width, considerably narrower posteriorly than anteriorly; 

 the anterior and posterior margins broadly rounded, the lateral 

 margins sinuate, the whole spineless; dorsum bearing four obsolete 

 tubercles centrally. Tegmina long, surpassing the abdomen, 

 about four times as long as broad. Anterior limbs with the 

 femora rather stout and heavy, the external margin bearing five 

 large and twelve small teeth, the internal margin bearing twelve 

 teeth alternating in size. Median and posterior limbs lightly 

 built, hirsute. Abdomen rather slender. Cerci damaged. 



General color grayish brown suffused, excef)i the tegmina, with 

 dull purplish brown. Clypeus, labrum and facial shield ochrace- 

 ous with four transverse blackish bars, the superior pair continued 

 upon the olive-tinged eyes, Pronotum with the suffusing tint 

 arranged in a pair of broken parallel lines along the mediaa 

 section, posteriorly tinged with green, the lateral margins being 

 thickly speckled. Limbs irregularly marked with the suffusing 

 tint, except the anterior coxse and the lower surface of the tibiae 

 which are pale yellowish, the internal section of the tibire being 

 broadly lined with black. Below dull yellowish except a single 

 band of black across the prosternum. Tegmina hyaline, the 

 longitudinal veins blackish irregularly broken by whitish spaces.
