LONG-HORNED GRASSHOPPERS. 



in the hot sun. Melanoplus femur-rubrum is the extremely 

 common, red-legged grasshopper of our fields, very similar 

 to M. spretus. The fat, clumsy, short-winged "Lubber 

 Grasshopper" of our Southeast is Romalea microptera 

 and the almost wingless Lubber of our Southwest is 

 Br achy pe plus magnus. 



1. Tegmina, especially of females, over an inch long. 



Schistocerca. 

 Tegmina rarely an inch long 2. 



2. General color green, in life; the least distance between 

 the eyes less than i>2 times the width of the second an- 

 tennal joint. Hesperotettix. The least common of these 

 four genera. 



Usually brownish; eyes more widely separated 3. 



3. Dorsal surface of pronotum not twice as long as the 

 average breadth, the sides constricted at the middle. 



Melanoplus. 



Dorsal surface of pronotum relatively longer, the sides 

 not constricted at middle Paroxya. 



TETTIGONIID^E 



A proper nickname for the Acrididae is " Locusts." This 

 used to be very confusing since the scientific name of the 

 long-horned grasshoppers, which are not "Locusts," was 

 Locustida2. It was recently discovered by some of those 

 whose business it is to find out such things that "Locusti- 

 dag" is not good usage. The matter is still sub judice but 

 I prefer the less confusing one. The Long-horned Grass- 

 hoppers may be distinguished from crickets (Gryllidae) 

 by the fact that their wing-covers slope down on the sides 

 and are not flat above except for a short space near the 

 base. Both families have long antennae; the males of 

 both sing or, better, fiddle by rubbing their wing covers 

 together; and both listen with "ears" which are situated 

 near the upper part of the tibiae of their front legs. 



Among those genera having hind wings, Scudderia 

 (tegmina of nearly equal breadth throughout) and Ambly- 

 corpha (tegmina widened at the middle) have no spines on 

 prosternum or vertex but have one on each side of the
