236 ENTOMOLOGICAL NEWS. [Sept., '06 



Form slender, slightly compressed. Head with the occiput distinctly 

 arched dorsad of the level of the pronotum ; interocular space nar- 

 rower than any portion of the frontal costa ; fastigium distinctly but 

 not strongly declivent, sulcate ; face considerably retreating ; frontal 

 costa broad, slightly but regularly expanding ventrad, not sulcate ; 

 eyes large, moderately prominent when viewed dorsad, subovate in 

 outline, the cephalic margin somewhat flattened, length about twice 

 that of the infra-ocular sulcus ; antennae slightly longer than the head, 

 pronotum and tegmina united, proximal joint narrower than the dorsal 

 section of the frontal costa. Pronotum slightly tectate, the dorsum nar- 

 row, the greatest width contained nearly twice in the length ; cephalic 

 margin arcuato-truncate, with a very slight median emargination ; meta- 

 zona very closely and deeply punctate ; median carina distinct but not 

 high, lateral carina indicated only by a blunt angle on both the pro- 

 zona and metazona, and a line of coarse punctures on the otherwise 

 smooth prozona ; principal tranverse sulcus distinct, cutting the median 

 carina at a point distant from the caudal margin about two-fifths the pro- 

 notal length ; lateral lobes very considerably longer than deep, the ceph- 

 alic and caudal margins oblique, ventral margin obtuse-angulate. Teg- 

 mina about four-fifths the length of the pronotum, subovate, the greatest 

 width about two-thirds the length, apical section rounded, subtruncate, 

 veins moderately distinct and closely placed, the sutural margins of the 

 tegmina separated by a space as wide as the frontal costa. Prosternal 

 spine erect, slightly retrorse, thick, blunt. Interspace between the meso- 

 sternal lobes nearly twice as long as broad ; metasternal lobes sub-attin- 

 gent. Abdomen distinctly compressed, except caudad, the extremity be- 

 ing but slightly upturned. Furcula as long as the segment from which they 

 arise, flattened, tips divergent. Supra-anal plate elongate-trigonal, deeply 

 sulcate mesad, broadly and rather shallowly sulcate laterad. Cerci tap- 

 ering in the proximal half, slender mesad, distinctly expanded distad. 

 rounded dorsad, and with a rectangulate lobule ventrad, the distal half 

 distinctly bent mesad, and falling slightly short of the tip of the supra- 

 anal plate. Subgenital plate with the apical margin strongly curved, the 

 apical tubercle thick, blunt and separated dorsad from the apical margin 

 by a depression. Cephalic and median femora robust, inflated, the ceph- 

 alic subfusiform. Caudal femora moderately slender ; caudal tibiae with 

 fifteen spines on the external margins. 



General color raw umber. Head with two widening patches of seal- 

 brown on the occiput, postocular bars distinct and moderately wide, of 

 shining black ; eyes burnt umber. Pronotum touched with burnt umber 

 dorsad ; postocular bar present on the prozona, slightly broader than 

 on the head and with the ventral border more undulate than the dorsad, 

 shining black. Tegmina near Prout's brown. Abdomen with a broad 

 bar of blackish on the lateral face, broken on most of the segments 

 into a blackish suffusion or blackish spots on the caudal margins of the 

 segment. Caudal femora touched with russet, the genicular arches and
