Stratocles costaricensis n. sp. 



Type.— 9 ; Costa Rica. (Schild and Biu-gdorf.) [Cat. No. 7,346, 

 U. S. N. M.] 



Apparently related to Phasma perspicillare Stoll,^ from which it 

 differs in the longer limbs and rather different color pattern, which, 

 however, resembles perspicillaris closer than any other species. 



Size medium; form elongate subfusiform; surface generally veluti- 

 nous and evenly pilose on the pronotum, mesonotum, limbs and ven- 

 tral surface. Head suborbicular when viewed from the dorsum, con- 

 siderably broader than the pronotum; occiput rounded; ocelh of 

 mediiun size; eyes ovate, moderately prominent; antennae exceeding 

 the body by over half the length of the latter. Pronotum longitudinal, 

 about twice as long as wide, subequal; anterior and posterior margins 

 subtnmcate ; cruciform depression very slight. Mesonotum shorter than 

 the pronotimi, posterior half sharply yet evenly elevated, width sub- 

 equal and shghtly narrower than the pronotum. ]\letathorax consider- 

 ably longer than the prothorax and mesothorax; metasternum plane. 

 Tegmina rather short, irregularly elongate-ovate ; costal area large and
