between the latero-proximal angles of the clypeus, extending caudad 

 as broad Unes along the juxta-mandibular portion of the genae, and 

 as three distinct dorso-ventral bars on the proximal half of the cly- 

 peus, one median, the others marginal: mandibles largely zinc orange: 

 eyes dresden brown: antennae yellow ocher, becoming ochraceous 

 tawny distad, with well-spaced annuli of mmnmy brown, these more 

 closely placed proximad than distad, the same section of the antennae 

 with the individual joints marked off by narrow shadow annuli of 

 mummy brown; ventral surface of second article barred transversely 

 proximad and distad with mummy bro-wn. Pronotum with a pair of 

 obliquely disposed spots of mummy broAvn laterad on the rounded 

 shoulder at the cephalic fifth; pair of similar but very much weaker 

 spots are placed immediately caudad of the transverse sulcus, the 

 four spots having a cruciform disposition; area of the median im- 

 pression washed faintly with mummy brown. Tegmina with their 

 base color mummy brown, the venation, primary and secondary, 

 forming a mesh work of warm buff to light buff. Wings infumate. 

 Ovipositor sanford's brown. Limbs ochraceous-buff, the femoral 

 spines (marginal) fuscous, with a fuscous spot surrounding the base 

 of each, apices of the caudal femora infuscate; external face of the 

 caudal femora with an oblique patterned area of fuscous, consisting of 

 two long lines and portions of a number of generally transverse, 

 briefly arcuate, lines: cephalic tibiae with a fuscous patch on each face 

 immediately distad of the foramina, the distal extremity also narrowly 

 infuscate ; median tibiae with similar areas in similar positions ; caudal 

 tibiae marked with fuscous proximad and distad, all tibial spines 

 tipped with fuscous, those of ventral surface with fuscous surrounding 

 their bases. 



Length of body (exclusive of ovipositor), 20 mm.; length of pro- 

 notum, 6.3; greatest width of pronotal disk, 3; length of tegmen, 

 19.8; greatest width of tegmen, 3.2; length of caudal femur, 14.5. 



The type of this most interesting species is unique.

 GryUacris harpistylata n. sp. (PI. II, figs. 46, 47.) 



Allied to G. Icevigata Brunner,^- but differing in the paired produc- 

 tions of the disto-dorsal abdominal segment being closely placed 

 mesad and spiniform, the whole segment more produced mesad, in 

 the cerci being reduced to brief stjdiform appendages, in the sub- 

 genital plate being large, moderately produced and having greatly
