1907.] XATURAL SCIKNCKS OF PIIILADELI'IIlA. 43 



ventral portion of the face the costal carinae expand in an undulating 

 fashion, sulcation distinct but not very deep, in fact shallow in the con- 

 stricted dorsal portion; eyes not prominent, somewhat shorter than the 

 infraocular sulcus; antenna) heavy, in length exceeding that of the 

 iicad antl pronotum combined by that of the head alone. Pronotum 

 \\ith the disk but very slightly tectate, prozona contained about one 

 and three-fourths times in the metazona; cephalic margin very slightly 

 arcuate, caudal margin rectangulate with the margins slightly undulate; 

 median carina very faintly indicated on the prozona, distinct but very 

 fine on the metazona; lateral angles faintly tuberculate on the prozona, 

 rounded shoulders on the metazona; lateral lobes of the pronotum with 

 the depth slightly exceeding the dorsal length, caudal margin descend- 

 ing with a slight cephalad trend, ventral margin irregularly rounded. 

 Interspace between the mesosternal lobes distinctly but not strongly 

 transverse; interspace between the metasternal lobes slightly trans- 

 verse. Tegmina four and a half times the length of the pronotum, 

 exceeding the apices of the caudal femora and the abdomen by the 

 pronotal length, the greatest width contained about four and a half 

 times in the length ; costal margin with the distal third regularly arcuate, 

 apex obliquely truncate; intercalary vein closer to the median than to 

 the ulnar vein throughout its length. Wings ample, rather broad, the 

 greatest width contained about one and three-fourths times in the 

 length; apex obliquely truncate, axillary field with the margin dis- 

 tinct arcuate. Abdomen with the subgenital plate rather broad ; cerci 

 simple, straight, substyliform, blunt. Cephalic and median limbs 

 rather slender; caudal femora robust, not strongly but regularly in- 

 flated, the ventral carina distinctly elevated, length about two and 

 ■one-half times that of the pronotum; caudal tibise with nine spines on 

 the lateral margins. 



General color pale ochraceous-buff overlaid with bistre. Head pale 

 ventrad and on the face, dark dorsad, genoe lightly mottled; eyes burnt 

 uml)er; antennas, except for the paler two proximal joints, clove brown. 

 Pronotum nearly uniform bistre. Tegmina with solid median and 

 proximal dark transverse bars/** the latter confluent with the base of 

 the tegmen and both extending solidly across the same," a premedian 

 bar is present but not as regular as the others, the pale interspaces 

 between the three bands being sharply defined and distinctly but not 

 greatly narrower than the average of the darker bars; apical fourth 



'" These bars are darker and nearly blackish on the costal field. 

 " The median is a little broken on the anal field.
