268 NEW NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



The measurements give the extremes of the series. The specimen doubtfully 

 recorded as tenuipennis by Scudder, from Monterey County, California, 

 is an aberrant example of that species, showing no approach toward the 

 present insect. 



We would note that in this species, as well as in tenuipennis, the degree of 

 expansion of the pronotum caudad is individually variable. The amount of 

 expansion, however, in the present species averages very distinctly greater. 

 The swelling of the cephalic portion of the pronotum also shows some individual 

 variation, but the present species always shows this feature to some extent, and 

 with its rugged structure and more strongly denned carinae is decidedly dis- 

 tinctive in appearance. 



Coloration. — Type. Head ochraceous- tawny becoming darker, cinnamon 

 brown, on the occiput, with a still darker, broad post-ocular bar of mummy 

 brown on each side. Pronotum with disk appreciably darker than lateral 

 lobes, cinnamon brown, with lateral carinae ochraceous-buff washed with 

 tawny; lateral lobes ochraceous-buff washed with tawny, this heavier caudad, 

 except on dorsal half of prozona, which, not including the cephalic margin, is 

 mummy brown with a conspicuous dorso-mesal fleck of ochraceous-buff 

 where the channel of the first sulcus terminates. 16 Tegmina and dorsal surface 

 of abdomen cinnamon brown. Cephalic and median limbs internally pinkish 

 buff, externally clay color with irregular flecks of blackish brown, these 

 markings heaviest distad on cephalic femora and mesad on median femora. 

 Caudal femora sayal brown; external face with a heavy proximal area of 

 blackish brown, another mesad which is larger and very broadly V-shaped 

 with apex mesocephalad, and another distad, the raised carinae bounding 

 this face pale, clay color; dorsal surface sayal brown, its external half immac- 

 ulate, the heavy median carina and internal half with three broad dark bands, 

 which continue on the internal face, disappearing there mesad; ventral surface 

 brilliant dragon's blood red, this color suffusing also the proximal portion of 

 the internal face. Caudal tibiae deep bluish gray green, with a broad proximal 

 annulus of cinnamon-buff; spines whitish, tipped with black. Ventral surface 

 cinnamon-buff. 



Only a moderate degree of intensification and recession is shown by the large 

 series at hand, the general coloration ranging from bister, with paler por- 

 tions sayal brown (intensive), to sayal brown, with paler portions clay color 

 (recessive). 



Specimens Examined: 187; 89 males, 97 females, 1 gynandromorph. 17 



California: Del Monte, Monterey and Guadalupe. 



16 This fleck is a distinctive feature in the present species; with hardly any 

 exceptions, being conspicuous in the large series before us. Hardly ever does 

 this marking appear in tenuipennis, and when present is inconspicuous. 



17 This specimen is remarkable in having the entire sinistral portion from 

 head to apex of abdomen male, the dextral portion female. As a result, due to 

 the disparity of size in the sexes of this species, this specimen is asymmetrical 

 throughout. This is the second gynandromorph examined by us, the first 

 being a specimen of the Tettigoniid, Insara elegans consuetipes (Scudder) 

 recorded by Rehn and Hebard, Trans. Am. Ent. Soc, xl, p. 81, (1914).
