former variegated with dusky spots, and semitransparent at 

 tip; wings next to the body yellow, sometimes pale, sometimes 

 deep and almost orange colored, at other times uncolored and 

 semitransparent; with a broad black band across the middle, 

 which is narrowed and prolonged on the hinder margin, and 

 extends quite to the inner angle; beyond the band the wings 

 are transparent, with the tips black or covered with blackish 

 spots ; hindmost shanks.whitish, with a black ring at each end, 

 a broader one of the same color just above the middle, and the 

 spines tipped with black. Length | inch to -^^ inch ; exp. 1^ 

 inch to more than 1| inch. 



The wings of this species are very variable in color at the 

 base. The fenestralis described by M. Serville has the base of 

 the wings vermilion red, but in other respects it approaches to 

 this species. The long-horned locust is found oftentimes in 

 company with the marbled species, and also near sea-beaches 

 with the maritime locust, from the last of July to the middle 

 of October. 



9. Locusta nebulosa. Clouded locust. 



Dusky brown; thorax with a slender keel-like elevation, 

 which is cut across in the middle by a transverse fissure; 

 wing-covers pale, clouded, and spotted with brown; wings 

 transparent, dusky at tip, with a dark brown line on the front 

 margin; hindmost shanks brown, with darker spines, and a 

 broad whitish ring below the knees. Length from -^q inch ^o 

 more than ly% inch ; exp. from 1 1 inch to more than 2 inches. 



A very common species, and easily known by its clouded 

 wing-covers and colorless wings. It abounds in pastures, and 

 even in corn-fields and gardens, during the months of Septem- 

 ber and October, at which time it is furnished with wings and 

 may often be seen paired or busied in laying eggs. It does 

 not appear to have been described before. 



The three following locusts differ from the preceding in 

 having the antennee shorter than the thorax, and sHghtly thick- 

 ened towards the end, and the face somewhat oblique, the 

 mouth being nearer the breast than in our other species of 

 Locusta ; and they seem to constitute a distinct group or sub-
