270 NEW NOKTH AMEEICAN MELANOPLI (ORTHOPTERA) 



Allotype. — 9 ; same data as type. [Hebard Collection.] 

 Similar to the male type except in the following features. Size decidedly- 

 larger; form robust, slenderest, however, for females of the species of Oedaleono- 

 tus. Pronotum similar, but with carinae and sulci all weaker. Tegmina very 

 broad, sub-circular, 21 separated by a very slightly greater interspace. Ovi- 

 positor valves normal for the genus.

Though the series shows little variation in contour and pronotal expansion, 

 the females exhibit decided variation in relative size of the tegmina. 



Coloration. — Uniform pale avellaneous on face, genae (except for a broad 

 post-ocular bar of clove brown and a subocular patch of the same color), ven- 

 tral half of the lateral lobes of the pronotum (except a hair line of clove 

 brown running down the second sulcus and curving cephalad in the mesal 

 portion of this area), cephalic and median limbs (which, however, are necked 

 and washed with dark brown, particularly on their external faces) and under- 

 pays. Antennae avellaneous with a decided cinnamon tinge. Eyes tawny 

 olive. Vertex and occiput, disk of pronotum (which, however, is paler toward 

 the lateral carinae) and tegmina, saccardos umber. Dorsal half of lateral lobes 

 of pronotum to principal sulcus occupied by a large, longitudinally rectangulate 

 area of shining clove brown, separated from the cephalic margin by a narrow 

 band of pale avellaneous; lateral lobes caudad of principal sulcus heavily 

 washed with saccardos umber. Dorsal surface of abdomen avellaneous washed 

 with saccardos umber, all but the distal segments heavily suffused laterad with 

 blackish brown, each of which markings is invaded by an area of avellaneous 

 meso-caudad; latero-proximal angles of subgenital plate heavily washed and 

 flecked with blackish brown. Caudal femora clay color, external and dorsal 

 faces crossed by three heavy, zig-zag bands of blackish brown, the two more 

 distal of which also cross the internal face. Caudal tibiae pinkish buff washed 

 and speckled with clay color, proximal spines blackish brown, distal (majority) 

 spines blackish brown, buffy proximad on their convex dorsal faces. 22 



A usual amount of color variation is shown in the se'ries, the intensive 

 extremes having the dark patch of the lateral lobes of the pronotum and bands 

 of the caudal femora very heavy and conspicuous. A few females are very 

 pale, one in particular being clay color fading to cinnamon-buff on the abdo- 

 men, caudal femora and tibiae, the femoral bands very weak, sayal brown, 

 showing only on the dorsal surface. 



21 In this sex rarely broad-ovate. 



22 This varies in the series to a condition in which the entire proximal portion 

 of the majority of these spines is buffy.
