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

 but 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, depressed, triangular, spinul- 

 iferous lamina, protecting the posterior coxffi ; 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 with laminated spines; 

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

 antennae swollen. Length of body 1.2 in. ; of antennaj 1.05 In. ; of 

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

 Napo or Maraiion. 



26. Phasma putidum Bates. 



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

 of both of the 9 measure 2.3 in. in length, or a little more than 

 those of Bates's specimens. 



27. P. Menius Westw. 



One 9 taken in Ecuador seems to be referable to Westwood's 

 species. The alternate joints of the antennae 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 no v. 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 tibise and tarsi black, 

 except externally ; a median spot on the interior surface of the tibiae, 

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

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

 S nearly hyaline ; wings hyaline, sprinkled with numerous quadrate,
