 This is the species treated in my former work (1JMK>, .">!>4) as 

 Atliuitk-its dorsal i# (Burin.), a name which K. & PI. have applied 

 to a form occurring in Georgia and Florida. In Indiana A. <l<icisi 

 has been taken from Marion and Putnam counties southward, and 

 occurs most frequently on the high rocky, thinly wooded slopes 

 of the southern counties where it is more abundant than tcsfa- 

 cci/s. From the latter species it may be readily known by the 

 shorter, less rounded hind lobe of pronotum, less exposed male 

 tf-gmina, longer and more slender apical portion of male cerci, and 

 by the tip of ovipositor being formed by the tapering of both mar- 

 gins, not the upper one alone as in testaccus. 



The known range of da vis i extends from Lake George, N. Y., 

 west to southern Iowa and south to southern Virginia. In the 

 eastern States it occurs in company with A. aincricainis among 

 the dead leaves and scattered undergrowth of deciduous woods.

Size and form, of A. ilawisi. Female "brown, the sides of pronotum 

 streaked with black, particularly at the posterior portion, also an inter- 

 rupted band of black on the outer sides of femora. Pronotum narrower 

 in front than behind, somewhat pinched before the middle, the lateral 

 carinse well defined. Ovipositor stout, swollen at base with a gradual up- 

 ward curve from about the middle and symmetrically narrowed to a point 

 from both above and below (Figs. 194, 195, d.) Notch of subgenital plate 

 U-shaped." (Davis). Tegmina of male covering about one-fourth of ab- 

 domen, their marginal field broader at base and narrowing toward apex 

 instead of quite narrow and subequal throughout as in clavisi. Length of 

 body, $, 17.G 19.8, 9, 2023.2; of pronotum, $, 89, 9, 8.39.9; of teg-

Lake Toxaway, N. Car., and Clayton, Ga. (l)<irix). The sin- 

 gle para type female at hand resembles that sex of davisi closely, 

 but differs in the narrower disk of pronotum, with lateral 

 carinse less convergent, its posterior lobe more rugose above Avith 

 angles much less rounded ; the distinctly shorter lower half of 

 lateral lobes with hind margins therefore much more oblique, the 

 lower hind angle more narrowly rounded and humeral sinus more
