both segments are equal in length, slightly longer than broad, and 

 opaque; remaining segments shining, gradually narrowed to the tip. the 

 sutures distinct. Length of body 8 lines; of antennas 11 i lines; of 

 abdomen 5f lines; expanse of wings 10 lines.

This species bears a remarkable resemblance in its form to that of 

 the males of 3fegischus, but it is not so linear, and the antennas are 

 almost twice as long ; the neuration of the wings is different, and the 

 hind legs are simple. Although the color of this species is much darker 

 than that of the preceding (S. cubensis), and the form more elongate, 

 still it may yet prove to be the male of that species, as the color and 

 neuration of the wings are the same and the sculpturing of the body 

 similar. 



Stenophasmus pusillus. n. sp. 



Ferruginous; legs and tip of abdomen tinged with dusky; antennae blackish, 

 as long as the body; wings subhyaline. 



Mate. — Uniform ferruginous; indistinctly sculptured; head rather 

 large, globose, the cheeks and occiput polished; antennas as long as 

 the body, very slender, piceous, tinged with ferruginous at base; lobes 

 of the mesothorax distinctly defined, the collar rather prominent; me- 

 tathorax minutely rugose above, smooth on the sides. Wings uniformly 

 pale f'uscodiyaline, slightly iridescent; nervures and stigma pale fus- 

 cous. Legs fusco-ferruginous, the anterior pair ferruginous. Abdomen 

 about twice as long as the thorax, sublinear, depressed; basal segment 

 long and slightly broader at tip, with two tubercles on each side be- 

 tween the middle and the base, the one near the base prominent, the 

 other one not so distinct; the suture between the second and third seg- 

 ments indistinct as in the preceding species ; remaining segments 

 shining, the apex slightly recurved and tinged with fuscous. Length 

 3i lines; expanse of wings 5 lines.
