entirely rugoso-punctate. Head with the dorsal length nearly three- 

 fifths that of the pronotum; occiput slightly arched, not elevated, 

 perceptibly descending to the interocular region, the interspace 

 being very narrow, hardly more than a fourth the greatest fastigial 

 width, not regularly narrowing, but of subequal width for some 

 short distance; fastigium transverse, slightly obtuse-angulate with 

 the apex subtruncate, the fastigial margins with a slight rim, the 

 surface of the fastigium slightly impresso-punctate ; fastigial process 

 when seen from the side not projecting beyond the line of the face, 

 the latter being but very slightly retreating, the fastigio-facial 

 angle very slightly rounded; frontal costa absent on the ventral 

 portion of the face, appreciably but not greatly narrowed dorsad 

 and ventrad, irregularly sulcate around the ocellus, 

 deeply punctate dorsad; lateral foveolar areas ,/ 



punctate; supplementary facial carinse con- 

 siderably divergent caudad; eyes eUiptical, very 

 distinctly longer than the infra-ocular portion 

 of the gense, moderately prominent when viewed // 



from the dorsum. Pronotum rounded transversely, 

 hardly tectate, the length slightly shorter than 

 the greatest caudal width; cephalic margin sub- 

 truncate, caudal margin truncate with a broad, 

 shallow median emargination ; median carina 

 distinct cephalad and caudad, very weak mesad, 

 transverse sulci three in number, prozona nearly ^^§'4^77? ^n^'^sp^ 

 twice the length of the metazona; lateral lobes Dorsal outline of 

 of the pronotum not separated from the dorsum ^^^^^ ^^f PJ°^«y 

 by distinct angles or carinse, rounding regularly (X 3.) 

 into the vertical lobes, longer than deep, cephalic 

 and caudal margins somewhat sinuate, ventral margin with a pro- 

 nounced ventro-cephalic emargination, obtuse-angulate caudad. 

 Mesonotum and metanotum very broadly obtuse-angulate emar- 

 ginate, the metanotum with the angle more apparent than the 

 mesonotum. Tegmina and wings absent. Prosternal spine rather 

 small, conical, acute; interspace between the mesosternal lobes 

 slightly transverse ; interspace between the metasternal lobes smaller 

 than the mesosternal interspace, slightl}^ transverse. Abdomen 

 moderately compressed, keeled; dorsal ovipositor jaws \vith their 

 external margin very bluntly serrate. Cephalic and median limbs 

 rather slender. Caudal femora about three times as long as the 

 pronotum, tapering, the medio-dorsal carina serrate, the ventro-
