d^. — Size rather small; form elongate; surface generally rugulose. 

 Head moderately elongate, subequal; occiput with four distinct spini- 

 form processes; interocular region with three triangularly disposed 

 rather blunt processes, the anterior one smaller than the other two, 

 and bearing upon their summits the ocelli; eyes subglobose, very 

 prominent; antennae equal to the body in length, first and second joint 

 about equal in length, the basal joint somewhat depressed; whole sur- 

 face with a number of evenly distributed spiniform tubercles. Pro- 

 notum about equal to the head in length, rather narrower than the 

 head, subequal in width, anterior angles with a slight projecting pro- 

 cess; anterior and posterior margins truncate; cruciform depression 

 with the transverse arm stronger than the longitudinal branch. Meso- 

 notum about twice the length of the pronotum, subequal in width, 

 somewhat elevated posteriorly; median longitudinal sulcus very dis- 

 tinct posteriorly, obsolete anteriorly; surface rugoso-tuberculate, four 

 spiniform symmetrically disposed tubercles flank the median line ; meso- 

 sternum rugose. Metathorax about equal to the pronotum and meso- 

 notum in length, metapleura and the metasternum sparsely and weakly 

 tuberculate. Tegmina about equal to the metathorax in length, 

 cylindrical-ovate in outline, the base and apex produced and angu- 

 late; median protuberance very distinct, high, rounded, compressed; 

 veins subreticulate, surface rather coriaceous. Wings extending to 

 the middle of the sixth abdominal segment, twice as long as broad; 

 apex subrectangulate. Abdomen with the six basal segments longi- 

 tudinal, decreasing in length distally; seventh dorsal segment two- 

 thirds the leng-th of the sixth; eighth segment considerably shorter 

 than, and ninth about equal to, the seventh segment, the latter com- 

 pressed, subrostrate and vnih the apical margin with a shallow median 

 ^'-shaped emargination ; cerci slender, straight and equal to the ninth 

 dorsal segment in leng-th; subgenital opercule slightly exceeding the 

 apical margin of the eighth dorsal segment, basally bullate, apical por- 

 tion compressed, rather rostrate, the apex itself with a shallow trian- 

 gular emargination. Limbs slender and simple; tibiae about equal to 

 their respective femora in length. Anterior femora equal to the teg- 

 mina, mesonotum and half of the pronotum in leng-th, basal flexure 

 marked; metatarsi slightly shorter than the remaining tarsal joints. 

 Median femora about equal to the pronotum and mesonotum in length ; 

 metatarsi slightly shorter than the remaining tarsal joints. Posterior 

 femora reaching to the middle of the third abdominal segment ; meta- 

 tarsi very slightly shorter than the succeeding joints. 



General color dull paris-green and prout's-brown intermingled.
