146 INSECTS OF MASSACHUSETTS. 



almost orange colored, at other times uncolored and semitranspar- 

 ent ; with a broad black band across the middle, which is narrow- 

 ed 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 whit- 

 ish, 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 T \ inch ; exp. 1 T \ 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 T S , T inch to more than 1 T \ inch ; exp. 

 from l\ 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 September 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 antennae shorter than the thorax, and slightly thickened to- 

 wards 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 subgenus, which may re- 

 ceive the name of Tragocepkala, or goat-headed locusts.
