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? 7 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 8 7 
inch to more than l-^ inch ; exp. from 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 
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 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-genus, which may receive the name of Tragoccphala , 18 or 
goat-headed locusts.

Dusky brown ; thorax with a slender keel-like elevation ; 
wing-covers faintly spotted with brown ; wings transparent, 
pale greenish yellow next to the body, with a large dusky 
[ 17 L. nebulosn must bo referred to (Edipoda . — Uhler.] 
[ 18 Tragocephala is synonymous with Gomphocerus , and L infuscata , L. viridi- 
fasciata , and L. radiata must be referred to it. — Uhler.]
