This species is included here on the single record of R. & H. 

 (1910, 1*40 ) who found it at Augusta, Ga., July 29, <k in moderate 

 numbers in a sandy area scatteringly covered with scrub oak." 

 It was described from various points in Texas and Barber Co., 

 Kansas, and west of the Mississippi has since been recorded from 

 Oklahoma, Arkansas and Minnesota. McNeill (lS99a, 306) says 

 that in Arkansas it is "a not uncommon species among vegetation 

 in the sandy bottoms and along the banks of streams." Somes 

 (1914, 88) states that in Minnesota it occurs only on sandy areas 

 along the Mississippi River in the southeastern part of the State. 



The specimens at hand are from Oklahoma and Bouita, Texas, 

 and have the hind tibitp glaucous as described by Scudder, but 

 Morse (1907, 48) says their color varies from deep blue to cherry- 

 red and R. & H. state that in their Georgia specimens "the color 

 of the caudal tibia 1 ranges from dark orient blue to nopal red." 

 Structurally the species is very close to angustipennis, but differs 

 especially in ils larger, stouter form and the longer, more parallel 

 furcula which, as there, lie wholly outside the ridges of the median 

 sulcus.

Series XIII. THE PACKARDII GROUP. 



The members of this group are somewhat larger and stouter 

 than those of the preceding Series. They differ mainly in the 

 much shorter widely divergent furcula and in the form of the 

 apical margin of the subgenital plate which is not subtruncate 

 and vaguely concave as there, but at extreme tip well rounded 

 and feebly thickened to form a small, backward projecting tuber- 

 cle. They all agree in having the pronotal disk with sides sub- 

 parallel in male, feebly divergent behind, female, hind margin 

 broadly obtuse-angulate or sub-rounded, median carina distinct 

 on metazona, wholly wanting on prozona ; tegmina equalling or 

 but slightly surpassing hind femora; supra-anal plate with apical 

 third depressed, gradually narrowed and usually separated from 

 the basal portion by an evident but narrow transverse ridge; cerci
