1869.] 341 [Scudder. 



metathorax bears a median prominence similar to that on the head, 

 bnt with the spurs scarcely so divergent, and bearing at the tip longer 

 and less frequent spinules ; posteriorly the lower edge of the pleura 

 of the metathorax is dilated into a flat, depres^d, triangular, spinul- 

 iferous lamina, protecting the posterior coxje ; it is about four fifths 

 of a line in length. The middle of the anterior half of each of the 

 first five abdominal segments supports a pair of divergent thorns, from 

 each of which a slender spiculiferous lamina extends backwards, those 

 of opposite sides meeting in the middle of the posterior border; the 

 sixth abdominal segment bears a median, elevated, rugose lamina, 

 bifurcate anteriorly, its ridge rounded and armed posteriorly with 

 three equal, triangular, compressed teeth ; behind this segment the 

 median carina is elevated and rugose. The legs throughout, but 

 especially the femora, are armed profusely Avith laminated spines ; 

 the hinder portions of the apices of the joints on the basal half of the 

 antennas swollen. Length of body 1.2 in. ; of antennae 1.05 in. ; of 

 hind femora .4 in. It is allied to A. Tisiphone Westw. One i from 

 Napo or Maraiion. 



26. Phasma putidum Bates. 



One 3 , two 9 and one pupa from Napo or Maranon. The wings 

 of both of the ? measure 2.3 in. in length, or a little more than 

 those of Bates's specimens. 



27. P. Menius Westw. 



One $ taken in Ecuador seems to be referable to Westwood's 

 species. The alternate joints of the antenna; are not marked at the 

 base with a broad whitish ring, excepting in a few instances near the 

 tip, and where the pale color extends also over the apex of the pre- 

 ceding joint ; the centre of the tegmina is elevated into a triangular 

 perpendicular lamina, the apex of which is rounded. The wings 

 measure slightly more than one and a half inches in length. 



MANTIDES. 



28. Stagmatoptera binotata nov. sp. 



Prothorax trigonal, the lateral border with small, flattened, laterally 

 projecting spines, those at the base of the legs smaller and more uni- 

 form than the others ; the spines of the fore tibia; and tarsi black, 

 except externally ; a median spot on the interior surface of the tibiffi. 

 near the point of reception of the apical tarsal spine, black. Teg- 

 mina green, a large median spot ferruginous, the inner edge in the 

 3 nearly hyaline ; wings hyaline, spi'inkled with numerous quadrate,
