188 PROCEEDINGS OF THE ACADEMY OF [May, 



ventral margin distinctly concave, apex bluntly acute-angulate: 

 caudal tibiae slightly shorter than the femora, moderately sinuate, 

 faintly expanded distad; external margin with seven spines, internal 

 margin with nine spines: caudal tarsi slender, elongate; metatarsus 

 and second ^oint subequal in length to the third joint. 



General color of the dorsum of the thoracic and proximal abdominal 

 segments pale morocco red. General color of the head and abdomen 

 oil yellow, on the occiput and postocular region of the head dull 

 blackish green: venter aniline yellow; cephalic and median femora 

 light cadmium, passing to pyrite yellow on the tibise; caudal femora 

 sulphine yellow proximad, passing regularly to olive-green distad; 

 caudal tibise and all tarsi olive-green; mesopleura with a decided 

 subcircular spot of buff yellow at the base of the median femora. 

 The clypeal suture and the ventral margin of the gense are lined with 

 black and the antennal fossae washed with the same; antennae of 

 the color of the face proximad, passing to bay mesad and distad; 

 eyes burnt sienna. Abdomen with the proximal segments margined 

 with black, the median segments with paired circular to ovate black 

 spots disposed along the median line; disto-dorsal abdominal seg- 

 ment lined with black next to the supra-anal plate, the extreme tip 

 of the latter similarly blackened; cerci with the points black tipped. 

 Caudal femora with the genicular arches black and a cloud of similar 

 character crossing the base of the genicular lobes; caudal tibiae with 

 the spines black tipped. 

 Allotype: 9 ; same data as type. [Acad. Nat. Sci., Phila.] 

 The characters here discussed are supplementary to those given for 

 the male sex. Form very robust : sculpturing as in the male but more 

 decided on the abdominal segments. Interocular width of the ver- 

 tex slightly more than one-half the interantennal width of the frontal 

 costa, weakly sulcate to bisulcate caudad: fastigium nearly twice as 

 broad as long, cephalic bounding margin of the impresso-punctate 

 surface, obtuse-angulate : frontal costa thickly impresso-punctate 

 dorsad, faintly narrowed at junction with fastigium: eyes slightly 

 less prominent than in the male, their length nearly twice that of the 

 infra-ocular portion of the genae: antennae about one and one-half 

 times as long as the head and pronotum together. Pronotum with 

 the greatest caudal width of the disk slightly greater than the great- 

 est length of the same, in transverse section arched: cephalic margin 

 of pronotal disk hardly emarginate, caudal margin less distinctly 

 emarginate than in the male; transverse carina well indicated but 

 more delicate than in the male: lateral lobes slightly deeper in pro-
