the angle of the scutu7n; yellow spots on episterna entirely absent on 

 left side, minute on right side ; abdomen more blackish, with yellow 

 borders to lower ends of terga but also with the posterior margin of 

 both terga and sterna yellow. Length of tegmina, 42 mm. 



Variations (6 specimens). — In coloration the specimens agree with 

 the type in lacking the yellow spot on the angle of the scutum, none 

 of them showing the least trace of it. This character separates this 

 race very distinctly from all the other forms so that it, more than any 

 of the others, deserves the rank of species. Scudder had six males and 

 seven females from Indefatigable Island, and he states that all except 

 two lack this spot, these two, however, showing but " a faint trace of 

 it." One female has the entire face yellow as in the type but the 

 others resemble the forms already described in the coloration of the 

 head. The inferior surface of the meso- and metathorax is, in most 

 of the specimens, si aty-olivaceous, but the lateral stripes on the meso- 

 sternum from the pro- to the mesothoracic coxal cavities are generally 

 not very distinct although faintly present. All have the abdominal 

 terga bordered inferiorly with pale yellowish, strongly resembling in 

 this respect the Iguana Cove form, but differing from them in that the 

 color is pi-esent also on the entire posterior margins of the segments, 

 extending more or less distinctly entirely across the dorsal aspect of 

 the abdomen and conspicuously bordering all the sterna. The color 

 of the tegmina exactly duplicates that of the Iguana Cove specimens. 



Length of tegmina of 7nale^ 42, 42, 45 = 43 mm. ; oi female^ 61, 



59. 45 = 55 mm. 



These figures are slightly greater than those given by the measure- 

 ments of the Charles Island specimens. Scudder's measurements also 

 show that the Indefatigable form is the largest. In collecting on Sey- 

 mour Island after being on Albemarle the greater size of S. m. im- 

 maculata was strikingly conspicuous. This race is, therefore, although 

 very distinct, more closely related to that at Iguana Cove than to any 

 other, differing from S. m. lineata in the larger size and in lacking 

 the lateral spot of the scutum. 



SCHISTOCERCA MELANOCERA var. ? 



From James Island. 



When we visited James Island in April, specimens of adult Schisto- 

 cerca were extremely scarce and no specimens were secured. Imma- 

 ture specimens were everywhere abundant. About the time the young 

 are born the old ones die. Scudder had one male and two females 

 from this island, and, according to him, they most closely resemble the
