the width of one of the eyes; fastigium moderately declivent, round- 

 ing into the frontal eosta, considerably excavate ; frontal 

 costa broad, nearly as wide as the interspace between 

 the eyes, slightly narrowing dorsad, subequal from 

 slightly dorsad of the insertion of the antennae ventrad, 

 broadly and deeply sulcate from slightly dorsad of the 

 ocellus, dorsal portion impresso-punctate; face consid- 

 erably retreating; eyes ovoid, not very prominent, dis- 

 tinctly longer than the infra-ocular portion of the sul- 

 cus; antennae slightly exceeding the length of the head 

 and pronotum combined. Pronotum verj' appreciably 

 constricted mesad; dorsum with the cephalic margin pig. 16.— Le- 

 arcuato-truncate, caudal margin very broadly obtuse- iotettix 

 angulate with the immediate angle subtruncate and the gp. ^ Dor- 

 lateral portions of the angles slightly sinuate, greatest sal outline

 rowly rounded, more decided on the metazona than (*X35^^' 

 on the prozona ; median carina very weak on the prozona, 

 moderately elevated on the metazona; principal transverse sulcus 

 placed very slightly caudad of the middle; lateral lobes slightly longer 

 than deep, ventral margin decidedly obtuse-angulate mesad. Tegmina 

 very slightly surpassing the tips of the caudal femora, subequal in width 

 for the greater part of their length, apex rotundato-truncate. Pro- 

 sternal spine conical, erect; interspace between the mesosternal 

 lobes strongly longitudinal, the width contained nearly twice in 

 the length, internal margins of the lobes slightly arcuate, caudal 

 angle hardly rounded; metasternal lobes contiguous. Furcula very 

 short, contiguous, spiniform; supra-anal plate crudely semi-ovate 

 in outline, the apex obtuse-angulate, laterad of which on each side 

 is placed another very slight angulation, proximal two-thirds of the 

 plate with a distinct median sulcus bounded laterad 

 ^^^^^^^^ by considerably elevated carinse, remainder of the plate 

 Ci /\7 appreciably excavate; cerci surpassing the apex of the 

 ^"^--......^jT^ supra-anal plate, considerably tapering in the proximal 



half, thence subfalciform and slightly excavate mesad 

 on the external face, when seen from the dorsum they 

 are moderately in-bowed in a sigmoid fashion; sub- 

 genital plate moderately produced, the marginal length 

 subequal to the proximal width, margin slightly arcuate 

 when seen from the side, form of the elevated margin 

 when seen from the dorsum semi-elliptical, the apex not
