equal to the head in length, longitudinal, sul:)equal except for a slight 

 anterior constriction; anterior and posterior margins subtruncate; 

 cruciform longitudinal and transverse sulci finely marked, but dis- 

 tinctly visible; anterior angles rotundato-emarginate; posterior half 

 with four more or less distinct raised longitudinal ridges. JMcsonotum 

 slightly longer than the pronotum, longitudinal, subequal in width, 

 posterior portion considerably but gradually inflated, surface with 

 four longitudinal rows of small tubercles, which posteriorly fuse into 

 rough ridges; mesopleura smooth, with a longitudinal low ridge; meso- 

 sternum smooth, rounded. JMetanotum twice as long as the meso- 

 notum; metasternum plane. Tegmina ovoid, not half the length of 

 the metathorax, discoidal protuberance rather sharp, longitudinal; 

 apex rather narrowly rounded. Wings large, reaching to the apex of 

 the seventh abdominal segment, slightly over twice as long as wide. 

 Abdomen about half again as long as the head and thorax; the six basal 

 segments longitudinal, gradually decreasing in length toward the apex; 

 seventh dorsal segment transverse, not quite half the length of the 

 sixth; eighth segment about twice the length of the seventh, very much 

 inflated apically; ninth dorsal segment bullate, bearing a shallow me- 

 dian depressed area which gives the plate a bimammillate appearance, 

 apical margin subtruncate ; cerci not quite equal to the ninth dorsal seg- 

 . ment in length, subequal and slightly depressed l^asally, acuminate 

 apically; subgenital opercule but slightly shorter than the eighth dorsal 

 segment, and exceeding the apical margin of the same, apical margin 

 evenly rounded with a very slight shallow median emargination. 

 Limbs very slender, the anterior and posterior femora subequal to their 

 respective femora in length. Anterior femora slightly exceeding the 

 entire thorax in length, basal flexure hardty visible; metatarsi very 

 slightly shorter than the remaining tarsal joints. Median femora equal 

 to the mesonotum and metathorax in length ; tibise somewhat shorter 

 than the femora; metatarsi slightly shorter than the remaining joints 

 of the tarsi. Posterior femora reaching slightly beyond the apex of 

 the fourth abdominal segment; metatarsi slightly shorter than the 

 remaining tarsal joints. 



General color of the upper surface slate-black lined and spotted with 

 emerald-green; head with seven distinct longitudinal lines; pronotum 

 with two large irregular blotches on the anterior half, four longitudinal 

 lines on the posterior part, and the entire margins of the same green tint ; 

 mesonotum with the lateral ridges and the four distinct rows of tuber- 

 cles of the overlying tint; tegmina with the basic color sohd except in 

 the discoidal and basal regions which are ochraceous-rufous, A-eins of
