in length. Limbs distinctly carinate. Anterior femora equal to the 

 metanotum and half of the first abdominal segment in length, basal 

 flexure very marked, median line of the inferior surface with two apical 

 spines; tibiae very slightly shorter than the femora, the superior sur- 

 face with a slight distal swelling ; metatarsi but little shorter than the 

 remaining tarsal joints. Median femora somewhat shorter than the 

 anterior femora, superior margins each with a slight preapical Idbe, 

 anterior and posterior inferior margins serrulate, the former with two 

 preapical spines, the latter with one, inferior median line with four 

 evenly distributed spines; tibiae not quite equalling the femora in 

 length, distinct subbasal and preapical swellings developed; meta- 

 tarsi about half the length of the remaining tarsal joints. Posterior 

 femora but slightly shorter than the mesonotum in length, slight 

 superior preapical lobes developed as in the anterior limbs, spine 

 arrangement as in the median limbs except that the median line bears 

 five spines; tibiae equal to the femora in length, the swellings of the 

 median limbs but slightly represented ; metatarsi about two-thirds the 

 length of the remaining tarsal joints. 



? . — Size large; form elongate. Head slightly ovate; occipital pro- 

 cesses acute, much as in the male, but large and distinct ; spines on the 

 posterior margin of the head small but acute; eyes subglobose; an- 

 tennae about equal to the thoracic segments in length, filiform, basal 

 joint depressed and with the lower surface concave. Pronotum about 

 equal to the head in length; margins as in the male; spines numerous 

 and rather regularly distributed, of moderate height, the anterior 

 pair slightly exceeding the others in size. Mesonotum slightly exceed- 

 ing the three basal joints of the abdomen in length, general shape very 

 similar to that of the male ; surface with numerous spines of not very 

 regular distribution, a defined lateral row of evenl}^ sized spines being 

 present; mesothoracic pleura well spined; mesosternum with over 

 twelve rather low spines. Metanotum not quite equal to the two basal 

 abdominal segments in length; median segment equal to the first 

 abdominal segment in length; metathoracic pleura with a longitudinal 

 row of about nine rather even spines. Tegmina rather more than 

 half the length of the metanotum (including median segment), ovate, 

 coriaceous; median protuberance low, rounded; venation very appa- 

 rent, subreticulate. Wings equal to the tegmina in length, costal and 

 discoidal areas subreticulate as in the tegmina. Abdomen with the 

 segments all more or less longitudinal; five basal segments subequal 

 in length; the first, second and third with a median pair of small 

 spiniform processes placed close to the apical margin; sixth. segment
