ond abdominal segment so noticeable in this species here 

 described. 



Description ( 9 , the $ unknown). — Head slightly flat- 

 tened above and densely covered with acute tubercles, usu- 

 ally with two groups, each comprising one larger tubercle 

 with some smaller ones, between the eyes standing forth a 

 little more prominent than the others. Eyes small, mod- 

 erately prominent ; ocelli not evident. Thorax indistinctly 

 carinate, rugose and tuberculate, the pronotum furnished 

 above on the posterior margin with a pair of blunt spines 

 or acute tubercles, distinctly longer and more conspicuous 

 than the others. Abdomen subcylindrical ; median segment 

 distinct, transverse ; third, fourth, fifth, and sixth abdominal 

 segments multicarinate, the carinas distinct but low and 

 nearly straight ; second segment with a somewhat conspic- 

 uous expansion on the posterior margin above; first, third, 

 and fourth segments with a small V-shaped expansion at the 

 same location ; seventh and eighth segments furnished above 

 on the posterior margin with a pair of longitudinally dis- 

 posed swellings, the pair on the seventh segment the larger; 

 operculum failing to reach the tip of the abdomen and angu- 

 larly emarginate apically. Legs stout, the fore femora con- 

 spicuously curved basally and a little longer than the meso- 

 notum ; all the femora and tibiae are more or less foliate 

 above and the femora of the middle legs especially have a 

 couple of very noticeable expansions on the ventral margins, 

 these expansions extending out laterally from the femora, 

 those on the cephalic margin being the larger ; the posterior 

 and intermediate tibise have one or two small foliations be- 

 neath. Cerci short, less than twice as long as broad, scarcely 

 surpassing the last abdominal segment.
