384 PEOCEEDIXGS OF THE XATIOXAL MUSEUM. VOL.XX. 



in the female more or less infuscated ; above the antennae brownish 

 fuscous, more or less tinged with castaneous; behind the eyes a broad, 

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

 above and below, with yellowish 5 antennae varying in length, being 

 relatively longer in southern than in northern examples, but generally 

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

 beyond testaceous, deepening into fuscous toward the tip, the apices 

 of the joints normally pallid. Upper surface of the pronotum of the 

 color of the top of the head, the upper half of the deflected lobes with 

 a very broad black band in continuation of that on the head, anteriorly 

 edged more or less distinctly, both above and below, 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 episterua 

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

 nearly following the division line between the metathoracic episterua 

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

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

 the cuneiform oblique yellow dash which lies between these two black 

 stripes. Hind margin of pronotum less distinctly angulate 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 fleckings down the 

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

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

 upper half of the geuicular 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 

 deep sulcus which, after interruption, is repeated again in the apical 

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

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

 thtin 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 tip 

 nearly as broad as the base, the apical margin rounded and subeinar- 

 ginate. 



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

 the South particularly, 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 pronotum and sub- 

 acuminate at tip. This form may receive the racial name texana.
