straw to a rather dark olive-brown above, 

 lighter and of a more olivaceous cast below. 

 The occiput generally shows the usual two 

 dusky longitudinal lines. Sides of pronotum 

 varied in middle third with dusky brown and 

 pale griseous, the ventral third light gray or 

 white. Episterna of melathorax with pale 

 oblique bands running downward toward 

 fossa 3. Hind femora brown above and 

 below; tibial groove greenish ; disk pale gray 

 or nearly white on proximal half, its midline 

 often dusky interrupted with pale, forming 

 two sub-distinct dusky spots on proximal 

 two-fifths of femora, which are indistinct in 

 dry specimens; inner side similar to outer 

 except that the ground-color is paler and the 

 spots darker.

This species though not widely spread was 

 locally very plentiful in the salt marshes, its 

 green and olivaceous tints closely matching 

 in color the marsh grasses in which it made 

 its home. The ground heneath was often 

 overflowed at high tide and offered a retreat 



*Owing to the large number of types on hand speci- 

 mens will be sent, for the accommodation of other 

 students of the family, to a number of collections in 

 various parts of the country, as follows : —

to myriads of fiddler-crabs, being much 

 wetter and of a wholly different character 

 from the situations frequented by macnlipen- 

 nis and aeqnalis. 



As has been stated this species closely 

 approaches macnlipennis. Some of the 

 brown females bear a superficial resemblance 

 to long-winged specimens of cnrtipennis, but 

 the antennae and head readily distinguish 

 them therefrom.

Compared with tnacnlipetittis, the vertex is 

 more nearly horizontal, more acute, more 

 angulate with the front in profile; more nar- 

 rowed between the eyes; the depression of 

 the central foveola further removed from the 

 apex. The face is more oblique ; the antennae 

 are shorter, more flattened toward base, and 

 more finely pointed. The disk of the prozona 

 is broader, its sides less incurved, their out- 

 lines formed by straight lines rather than 

 curves, and the metazona very nearly as long 

 as the prozona. 



From aeqnalis also it is readily distin- 

 guished by the characters of the head and 

 vertex mentioned above, while the disk of the 

 pronotum is proportionally much more nar- 

 rowed anteriorly and the metazona much 

 longer. 



In sorting these species I have found it 

 easier, owing to their larger size, to separate 

 the females first. 



It seems best to make a few statements
