the disk above. The discal field with only a faint indication 

 of dusky spots. Posterior femora without indications of 

 dusky band ; the posterior tibiae testaceous with a purplish 

 ting'e towards base. Tegmina considerably narrower than in 

 the preceding- species but little surpassing the tips of the 

 abdomen. 



Length: of body, female 24 mm: pronotum 4-4.5 mm; 

 tegmina 19 mm: hind femora 14 mm; antennae 7 mm.

A much slenderer form than either of the tM'O j^receding, 

 with the fastigium of the vertex forming a right angle, and 

 having the lateral carinae of pronotum parallel to trans- 

 verse incision, from this jDoint to back edge of pronotum 

 somewhat bowed, but diverging as in the other species. 

 Tegmina and wings just reaching the posterior extremity of 

 hind femora which slightly surpass the tij) of abdomen. The 

 characteristic features of this species are the numerous dark 

 and light stripes and bands which adorn the body and wings. 

 General color of insect dull testaceous: occiput with two 

 slender dark lines arising near the middle of fastigium and 

 directed backwards upon the head almost to front edge of 

 pronotum, enclosing a stripe of nearly equal width to fas- 

 tigium of general color of body : a rather broad strii3e from 

 back edge of eyes to front of pronotum along the upi3er 

 edges of lateral sides of which it continues across this to 

 discal field of tegmina. This stripe also crosses lower half of 

 eyes to face and there separates forming two rather large 

 black bands, giving the face a very peculiar appearance. Be- 

 low this on the face, cheeks, and sides of pronotum is another 

 rather broader testaceous band which continues as the light 

 costal edge of tegmina. Again below this is an idication of 

 dusky bands relieved by smaller stripes of a light color. The 

 femora and tibiae of all the legs are duskv and have the
