large rounded projection on each side of the median carina. Mesonotum and 

 metanotum with a distinct medio-longitudinal carina, this raised and forming 

 with the caudal margin a small, acute projection on each segment; tegminal 

 and wing pads distinct, produced. Median segment with median carina weak 

 but caudad more strongly produced dorsad than the metanotum, forming with 

 the caudad margin a small acute projection. First, second and third dorsal 

 segments with caudal half of dorsal surface produced dorsad in large, delicate, 

 foliaceous plates, each plate so formed that its irregularly scalloped and 

 bluntly angulate margins represent a continuation of the caudal margin of 

 its respective segment; each of these segments with latero-caudal angles pro- 

 duced in a small, roundly subquadrate plate; fourth segment with a dorso- 

 caudal projection much like that of the median segment but larger, this and 

 the fifth segment with latero-caudal angles produced in still smaller, rounded 

 plates; fifth and succeeding segments with their entire dorsal surfaces (due to 

 their brevity) each occupied by a medio-longitudinal projection ascendent 

 caudad, each similar to but distinctly smaller than that of the fourth segment. 

 Supra-anal plate elongate shield-shaped, with a distinct medio-longitudinal 

 carina, projecting as far as apex of subgenital plate, apex rather broadly 

 rounded. Venti'al abdominal segments each produced raesad at the caudal 

 margin, forming with that margin a very small rounded projection directed 

 ventrad. Limbs elongate and slender; cephalic limlxs as in tristani, except as 

 noted above. Sul^genital plate developed distad in a valvular process nearly 

 half as long as the distance from its base to base of subgenital plate, jjrocess 

 with a medio-longitudinal ventral sulcation to its base, which is formed by a 

 transverse, broadly V-shaped sulcation of the surface of the plate. 



Length of body, 32; pronotum, 10.6; pronotal collar, 3.7; pronotal shaft, (j.9; 

 process of first dorsal abdominal segment, 3.6; dorsal portion of supra-anal 

 plate, 2.3; cephalic coxa, 7.4; cephalic femora, 9.8; cephalic tibia, 3; caudal 

 femora, 10.2; caudal tibia, 10.4; caudal metatarsus, 5.7 mm. Width of pronotum 

 at supra-coxal swelling, 2.9; pronotum at narrowest point of shaft, 1.1 ; process 

 of first dorsal abdominal segment at widest point, 2.7; cephalic femur, .8 mm. 



General coloration warm bufT marbled and flecked with mummy brown. 

 Abdomen with median portion of dorsum and median portion of foliaceous 

 projections suffused with mummy l)rown. Ventral siu-face suffused with 

 mummy brown. Cephalic coxa warm bufT, flecked with mummy brown and 

 with two median, irregular, transverse bands of this color on the external face. 

 Cej)halic femur light buff washed with mummy brown in three broad, irregular 

 transverse bands. Cephalic tibia light buff with two internal irregular suffu- 

 sions of mummy brown. Median and caudal limbs mummj' brown with 

 irregular annuli and flecks of light buff. 



The type of this remarkable niautid i.s unique.
