3**^4 PnOCEEDIXGS OF THE XJTIOXAL AfrSEF^V. vol.xx. 



ill tlie female more or less iiifuscated ; above the antenna' brownish 

 fuscous, more or less tinged with castaueous: behind tlie eyes a broad, 

 straight, horizontal, black band, edged more or less distinctly, both 

 above and below, with yellowish: antennae varying in length, being 

 relatively longer in southern than in northern exaniides, but genenilly 

 about two-thirds as long as the body in the male, yellow at base, 

 beyond testaceous, deepening into fuscous toward the tip, the ai>ices 

 of the joints normally i)allid. Upper surface of the pronotuni of the 

 color of the top of the head, the upi)er half of the deflected lobes with 

 avery l)road black band in continuation of that on the head, anteriorly 

 edged more or less distinctly, both above and beh»w, with yellowish 

 and generally fading out before, or abruptly terminating at, the meta- 

 zona (in the earlier stages it continues uninterruptedly across the pro- 

 notum, and this persistence is occasionally shown in the adult, or is 

 indicated on the metazona by a brown band sometimes percurrent and 

 usually reduced in width); pleura with a horizontal stigmatal stripe 

 running backward from the hinder edge of the mesothoracic episterna 

 (sometimes confined to the mesothoracic epimera), and an oblique stripe 

 nearly following the division line between the metathoracic episterna 

 and ejumera; when the lower stripe is complete it renders the meta- 

 thoracic episterna conspicuous, especially in the male, on account of 

 the cuueitbrm oblique yellow dash which lies between these two black 

 stripes. HiTid margin of pronotum less distinctly aiigulate — that is, 

 more uniformly rounded — than in the other species, though the differ- 

 ence is but slight and sometimes disappears. Tegmina nearly uniform 

 brownish fuscous, often with a faint line of small Heckings down the 

 middle in the female. Legs of the color of the body, the middle and 

 hind femora generally more or les^ infuscated on their outer face, the 

 upjier half of the genicular lobes of the latter black ; hind tibiae glaucous 

 with black or blackish spines. Supraanal plate of male long triangular 

 with a broad mesial rounded ridge extending two-thirds its length, on 

 the summit of which, in the basal half of the plate, is a very narrow 

 deei) sulcus which, after interruption, is repeated again in the apical 

 toartli; furcula consisting of a pair of moderately long, moderately 

 slender, cylindrical, slightly tapering, blunt, adjacent fingers (shorter 

 than usual in the specimen figured and drawn too stout), often diver 

 gent; cerci lamellate, very long, strongly incurved, gradually narrow- 

 ing and then as gradually enlarging, so as to make the spatulate ti]) 

 nearly as broad as the base, the ax)ical margin rounded and subemar- 

 ginate. 



The tegmina are ordinarily of about the length of the body, but, in 

 the South i)articularly, it often occurs with tegmina only reaching a 

 little beyond the middle of the abdomen. I have seen one such from 

 Massachusetts; and in a pair from Fort Worth, Texas, in the National 

 Museum the tegmina are scarcely longer than the ]>ronotum and sub- 

 acuminate at tip. This form may receive the racial name iexana."
