grasshoppers of Charles Island. In fact the females of the former 

 are but slightly larger than the males of the latter. This difference is 

 especially noticeable to one collecting at the two places, and there can 

 be no doubt that the smaller size of the Tagus Cove specimens is a 

 character distinguishing them as a race from those inhabiting Charles 

 Island. Scudder's sixteen inales and seven females from Albemarle 

 average considerably larger than those of the Stanford collection, but 

 he does not state on what part of Albemarle they w^ere collected, and, 

 as will be shown, there is a different race at the sovith end of Albe- 

 marle, and there might be another on the east side. 



SCHISTOCERCA MELANOCERA PALLIDA var. nov. 



From Barrington Island. 



Description of the Type. Female. — Similar to 6". 7n. minor of 

 Tagus Cove, but differing from the type of that variety in having the 

 metazona of a pale yellow color with but little black, in having a pale 

 yellow area on the side of the scutum near its lower margin, and in 

 the larger size of the episternal yellow areas. Length of the tegmina, 

 51 mm. 



Variations (11 specimens). — The Barrington specimens average 

 distinctly paler than the Tagus Cove specimens. The infuscation of 

 the apical half of the postmedian area of the tegmina is much less in 

 the males than in the Tagus Cove males, the same area being marked 

 with indistinct dark spots. The three females, however, have the 

 tegmina about the same color as those of S. ?n. minor. They all pos- 

 sess the yellow spot on the angle of the scutum, and all the males 

 and two of the females have a second less distinct and less well-defined 

 blotch of the same color near the lower margin of the scutum and 

 prsescutum. Scudder's figure, drawn from a Barrington Island speci- 

 men, shows this lower yellow area. One Tagus Cove specimen also 

 possesses this spot pretty well marked on each side. 



Length of tegmina of male^ 39, 40, 37, 38, 37, 43, 39, 39 = 39 mm. ; 

 oi female.^ 49, 50, 51 ^ 50 mm. 



The Barrington form is then closely related to the Tagus Cove form 

 and is related to it more closely than to any of the other races. It 

 differs from kS. m. minor chiefly in the lighter colored tegmina of 

 the males, and in the greater frequency of the lower yellow spot on 

 the side of the scutum, the absence of this mark being exceptional 

 while with the Tagus Cove form its absence is characteristic. Their 

 affinities, hence, are not with the Duncan race as Scudder judged from 

 his specimens.
