1904.] NATURAL SCIENXES OF PHILADELPHIA. 103 



Head with the spines clear green ; eyes wahiut-brown ; antennae green- 

 ish, each segment with a narrow apical annulus of brown. Mesonotum 

 with the larger spines tipped with clear brown. Tegmina with the 

 median protuberances clear green. Wings with the costal and discoidal 

 regions bearing strongly contrasted blotches of the two colors washed 

 with an ochraceoiis tint; posterior field smoky-hyaline. Limbs with 

 the usual coloration, but the tibiae have the green clear and vitreous. 



? . — Size medium ; form moderately elongate ; surface rugosc- 

 tuberculate. Head somewhat longitudinal, subeciual in width; occi- 

 put bearing about twelve formidable spines ranged in four longitudinal 

 series, of which the median pair contain the greatest number of spines 

 and the posterior ones of which are recurved and considerably larger 

 than any of the others ; interocular region with the ocellar spines much 

 reduced, the anterior one practically obsolete, the ocellus but slightly 

 raised above the surrounding surface; eyes subglobose, moderately 

 prominent; antennge wdth the basal joint strongly depressed; entire 

 dorsal surface sprinkled with small spiniform tubercles. Pronotum 

 slightly shorter than the head, very strongly emarginate over the ante- 

 rior coxae; anterior margin broadly and evenly emarginate, posterior 

 margin truncate ; median line flanked by a longitudinal row of several 

 short spines. Mesonotum not quite twice the length of the pronotum, 

 subequal in width ; no median carina or sulcus present ; surface strongly 

 rugoso-tuberculate ; mesopleurse and mesosternum rugoso-tuberculate, 

 the lower margins of the former and the lateral borders of the latter 

 bearing distinct tuberculous ridges. Metathorax slightly longer than 

 the other thoracic segments together; metasternum obsoletely tuber- 

 culate ; metapleurte bearing along their lower margins a series of four 

 distinct rounded tubercles. Tegmina equal to the head, pronotum and 

 mesonotum in length, elongate-elliptical; apex narrowly romided; 

 tubercle placed distinctly anterior to the middle, high, roimded, com- 

 pressed; surface coriaceous, subreticulate, and bearing a number of 

 small node-like projections. Wings about equal to the abdomen in 

 length; costal and discoidal areas with the transverse nervures rather 

 regular in character. Abdomen depressed, each segment with the 

 lateral margins developed into a more or less crenulate foliaceous flap ; 

 the five basal segments longitudinal, the fifth broader than the others; 

 sixth segment quadrate; seventh, eighth and ninth segments trans- 

 verse, decreasing in length distally, median carina present on the sev- 

 enth and represented by two parallel ridges on the eighth, ninth seg- 

 ment crcnulato-truncate; cerci slender, almost equal to the ninth dor- 

 sal segment in length, apex blunt ; subgenital opercule rather short,
