specimen,, the form is smaller than in the average of Imibata, while 

 the pronotum is distinctly though slightly constricted cephalad of the 

 supra-coxal expansion. The wings are purplish black caudad while 

 the tegmina are green. The left cephalic femur, tibia and tarsus of 

 this specimen have been regenerated ; the femur being slightly smaller 

 than the right but otherwise normal, the tibia is a short rounded joint 

 not a third the femoral length with the margins unarmed, while the 

 tarsus is quite short. 



PHASMID^. 

 Diapheromera arizonenais Caudell. 



September 7, 8 and 15, October 17 and 20, 1904, 21 9 . 



As the female of this species has not been well described, some notes 

 may prove of service. 



Wlien compared with a female of D. femorata from Philadelphia, 

 arizonensis is seen to be somewhat more robust, the head is distinctly 

 broader and the eye larger, while the proximal joint of the antennse 

 is narrower. The median segment is slightly more transveres than in 

 femorata, and the cerci are much shorter and blunter, while the three 

 distal abdominal segments are distinctly shorter and the subgenital 

 opercule is provided with a distinct apical finger-like lobe. Limbs 

 slightly longer than in femorata with the femoral spines distinct. 

 When compared with the closely allied JMexican D. calcarata, the 

 female of arizonensis is seen to be somewhat slenderer, but with a 

 broader head. The structure of the abdominal appendages and the 

 terminal segments is the same as in calcarata, but the. limbs of the latter 

 species are distinctly more robust. 



AORIDID^. 

 Orphulella graminea Bruner. 



September 30, October 4-5. 14 c?, 14 9 . 



These specimens agree with four paratypic specimens, two of each 

 sex, received from Prof. Bruner. In size the majority of the female 

 individuals are somewhat larger than the paratypic specimens, but no 

 larger than the original measurements. In color some are distinctly 

 mummy brown, others vinaceous-cinnamon and russet. The dis- 

 coidal area of the tegmina is quite distinctly marked with quadrate 

 blotches in about half of the specimens. 

 Encoptolophus texensis Bruner. 



September 24. 1 ?. 



This specimen has the head, pronotum, pleura and dorsal aspects of 

 the caudal femora suffused with pale green.
