54 rROCEEDISiiS OF THE XATIOXAL ^f'SECM. vol.xx. 



carina aharp, equal aiMli)erfurreiit, the lateral carinae distinct but con- 

 fined to the anterior lobe of tlie pro/.ona, and somewhat approximated, 

 the two sections of the prozona indcpen<lently and rather abruptly 

 tumid on the upper part of the lateral lobes, the transverse sulci of 

 the prozona obscure but straijifht, the front niarjjin truncate, the hind 

 marji'in produce<l but obtusangulate. Prostenial spine sluirply acumi 

 nate; meso- and metastethia together much longer than broad; tlie 

 mesosternal lobes approximate in the male, the metasternal attingent. 

 Tegmiiia abbreviate, broad lanceolate, acuminate, attingent. Hind 

 femora not very long, the l(>wer genicular lobe ])allid except for a nar- 

 row, basal, transverse, fuscous streak; hiiul tibiae with V2 spines in 

 the outer series. Abdomen of male compressed, the subgenital plate 

 equal, its middle with a i)ronounced, backwartl ilirected, apical tubercle, 

 the lateral m.i^idns basally ampliate; furcula distinctly developed: 

 cerci styliform, .xraight, acuminate. 

 A single species is known, from Florida. 



EOTETTIX SIGNATUS, new species. 

 (Plate IV, fi^r. 7.) 



Pizoteitix signatn McNeill I, MS. 



Of medium size, glistening flavo-testaceous. Head prominent, light 

 fusco-olivaceous, above broadly infuscated along the middle line and 

 with a narrow piceous postocular stripe, bordered by Havous; vertex 

 feebly tumid, not rising above the level of the pronotum, the interspace 

 between the eyes fully half as broad again as the first antennal Joint; 

 fastigium almost twice as broad anteriorly as posteriorly, little deeli- 

 vent, broadly and shallowly sulcate; frontal costa distinctly percur- 

 rent, equal below the ocellus, distinctly broader above it, so as to be as 

 broad there as the interspace betw^een the eyes, the lateral borders ele- 

 vated throughout but rounded and not acute, densely punctate through- 

 out; lateral carinae of face prominent; eyes large, very prominent, 

 nearly half as long again as the infraocular portion of the genae; 

 antennae luteous. Pronotum equal, in no way flaring on the metazona, 

 the lateral lobes with a not very broad, percurrent, glistening, blackish 

 fuscous, postocular stripe, directly beneath which the lateral lobes are 

 more brightly coh)red than below; disk broadly convex, passing into 

 the vertical lateral lobes almost insensibly, except on the anterior sec- 

 tion of the prozona, where there are distinct lateral carinae, which are 

 separated iron) each other by only about three-fourths the entire width, 

 of the prozona; median carina sharp, i)ercurrent, eiiual, but on the 

 metazona diminishing posteriorly; front margin truncate, hind margin 

 bluntly obtusangulate; prozona distinctly longitudinal, sparsely i)unc- 

 tate, nearly half as long again as the rather closely and finely punctate 

 metazona. Prosterual spine small ajid rather short, acutely conical; 

 interspace between mesosternal lobes very imrrow, nnich more tliaii
