incomplete. Pronotum with the general form much as in sordidus 

 but with the disk broader, the greatest caudal width of same con- 

 tained one and one-third times in the greatest length: lateral lobes 

 with the general form more quadrate than in sordidus, the ventral 

 margin being obliquely arcuato-truncate caudad, the ventro-caudal 

 angle rotundato-rectangulate, humeral sinus as in sordidus. Teg- 

 mina but slightly exceeding the apices of the caudal femora, form 

 similar, reticulations slightly coarse; discoidal vein with three distal 

 rami, median vein diverging from the discoidal vein slightly proxi- 

 mad of the middle of the tegmina; stridulating field relatively 

 simple, no distinct tympanum, stridulating vein no stronger than 

 the other reticulations of the field. Wings surpassing the tegminal 

 apices. Sternal plates of the types found in L. sordidus, but the 

 meso-and metasternum are more decidedly transverse with the 

 caudo-lateral angles more broadly rounded. Disto-dorsal abdom- 

 inal segment arcuato-truncate dorso,-mesad, with a shallow and very 

 broad median emargination : supra-anal plate trigonal: cerci sur- 

 passing the subgenital plate, tapering, straight in the proximal four- 

 fifths, the distal fifth slightly flattened and bent inward and dorsad, 

 the immediate apex weekly uncinate, surface of the proximal por- 

 tion of the cerci delicately tuberculate: subgenital plate narrowing 

 distad, the distal margin truncate, styles very brief articulate nodes, 

 ventral surface of the plate with a medio-longitudinal carina and 

 converging paired ridges, which distad carry the styles. Caudal 

 femora four-fifths as long as the tegmina, rather strongly inflated 

 proximad, ventral margins unarmed, genicular lobes very weakly 

 l)ispinose: caudal tibiae subequal to the femora in length. 



General color chamois, becoming honey-j^ellow on the dorsum of 

 the abdomen, the tegmina with their base color and also that of the 

 wings mars -brown. Head with paired arcuate facial hues of mars- 

 brown; eyes auburn; antennae (incomplete) hazel, sparsely annulate 

 proximad with blackish. Tegmina with the stridulating field 

 largely chamois, the sutural margin netted with wax-yellow, the 

 humeral trunk, reticulations of the marginal and adjacent portion 

 of discoidal field and costal margin primuline-yellow proximad, 

 passing into bice-green distad. Abdomen with a broad medio- 

 dorsal blackish -fuscous line; cerci tipped with same. Caudal tibiae 

 pale absinthe -green, becoming ochraceous-tawny. 



Doubtless the original coloration of this insect was largely green 

 or greenish, as traces of green are evident on the disk of the pro- 

 notum.
