390 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERA) 



brown, lateral lobes with dorsal half shining blackish brown to principal 

 sulcus, below this prout's brown, shading dorsad in metazonal portion to 

 mummy brown. Dorsal surface of abdomen cinnamon brown, very heavily 

 and broadly suffused laterad on proximal tergites with shining blackish 

 brown, small exposed portion of eighth tergite of this color and distal portions 

 of cerci darkened. Cephalic and median limbs buckthorn brown, except the 

 dorsal surfaces of the femora which are very dark mummy brown. Caudal 

 femora cinnamon brown, with proximal median, distal and genicular areas 

 of very dark mummy brown in the characteristic Melanoplid pattern, the 

 darker areas very heavy; ventral surface dragons-blood red (brazil red in the 

 most brilliant examples), paling to light coral red on the internal face dorsad, 

 with a narrow pregenicular buffy annulus and the internal face with three 

 large heavy suffusions of liver brown dorsad. Caudal tibiae gobelin blue, 

 the spines black, the spurs buffy, black tipped, the tarsi buffy. 



Slight recession from the described type is shown, except in the females 

 from High Creek among which a strongly recessive type is developed. In 

 these the general coloration is walnut brown and burnt umber, the posto- 

 cular bar alone darker, the color pattern weaker. The caudal femora have 

 the ventral surfaces bittersweet orange, while the caudal tibiae are glaucous 

 blue. 



Specimens Examined: 70; 16 males, 53 females and 1 immature individual.

At Vivian Creek the species was found rather abujulant in 

 the thin, dry and rather scanty grassy ground -cover in a ravine 

 forest of massive conifers. At High Creek it was less alnnidant 

 in a more open meadowy ravine, heavily carpeted with richer 

 grasses, surrounded by a conifer forest of smaller trees than at 

 Vivian Creek, and immediately above which the forest of Lodge- 

 pole Pines began, extending upward to timl)er line. We do not 

 believe that the distribution of the species extends into that 

 forest, in which the undergrowth is very scanty and grasses prac- 

 tically absent.
