There are specimens in the collection of the writer coming from Florida and Texas, 

 and there is but little doubt that the distribution includes Northern Mexico as well. 



L1TOSCIETUS, gen. nov. 



Related to both Dictyophorus and Tceniopoda in some of its characters, but differing from them in others, as 

 will be seen by a reference to the synopsis of the genera {anted, pp. 209-222). 



Pronotum provided with distinct lateral carinae throughout ; the median carina prominent, subcristate, 

 slightly arcuate both in front and behind the principal sulcus, on the anterior portion gently trilobed ; 

 the disk rugosely wrinkled. Antennae short, coarsely filiform, gently clavate. Head a little narrower 

 than the front edge of the pronotum, the vertex about as wide as the shortest diameter of one of the 

 eyes in the male, in the- female a little wider, the fastigium only gently depressed, rather profoundly 

 sulcate and furnished with a median longitudinal carina which enters it from behind, not quite complete 

 in the male ; frontal costa reaching the clypeus, fairly prominent, contracted at the sides just below the 

 ocellus, deeply sulcate in the vicinity of the latter. Tegmina and wings complete, the former coriaceous, 

 rather closely veined, of moderate width, the apex rounded and extending beyond the tip of the abdomen 

 in both sexes, the wings about twice as long as broad, the area of dilation and parallel veins inconspicuous. 

 Hind femora robust, about reaching ( $ ) or slightly surpassing the tip of the abdomen ( <$ ), their superior 

 carina distinctly serrate ; hind tibiae nine-spined externally, eight-spined internally, those on the inside 

 slightly largest. 



1. Litoscirtus insularis, sp. n. (Tab. III. figg. 0, 6 a, $ .) 



General colour brownish-testaceous, more or less plainly marked with piceous on the pronotal carinas. 

 Tegmina irregularly marked with dark brown flecks and blotches, especially on the costal margin and in 

 the discal area of the basal half; wings yellowish hyaline, with the veins and veinlets of the apical 

 portion and costal area dark brown, the apical portion slightly infuscated. Hind femora dimly bifasciate 

 with fuscous across the upper edge and outer face, internally on the basal half and the lower sulcus 

 black. Tibiae brownish-testaceous, the spines black-tipped. 



Length of body, S 25, $ 38 ; of pronotum, S 9, $ 11 ; of tegmina, <$ 25, § 32 ; of hind femora, c? 14, 

 5 18 ; of antennae, J 8, $ 9 millim.

All of the specimens examined seem to have been preserved in alcohol and afterwards 

 pinned, and accordingly have lost their colours or have them somewhat modified.

The genus Tceniopoda, with T. superba as type, is a much larger one than has here- 

 tofore been generally conceded. The material at hand indicates upwards of a dozen
