A paratypic male from Yosemite Valley and another of the same 

 sex from Wawona, taken September 1, have been examined in addition 

 to the types. The paratypic male is slightly larger than the type male 

 and has the pale general . color darker, more vinaceous-cinnamon, 

 while the Wawona specimen is similar to the type in size and is almost 

 uniform pale cinnamon in color, the seal-brown limited to the femoral 

 line and scattered clouds, spots and points, the pronotum being prac- 

 tically uniform except for the beading on the caudal margins. The 

 antennae are similar in pattern in all the specimens. 



The two specimens taken in the Yosemite Valley were captured 

 during the morning, hiding in the cracks in the bark of some tall fir 

 trees. They were quiescent, apparently resting for the day. The 

 individual taken at Grouse Creek was found on a steep hillside, 

 among a very few low green plants growing in a conifer forest. The 

 insect jumped about actively, but only for short distances. The 

 Wawona representative was taken from the stem of a small shrub, 

 where it was stridulating at dusk. Other specimens were heard 

 in the forest, usually in low trees. The stridulation is remarkably 

 faint for so large an insect, the sound produced being a weak zip- 

 zip-zeeeeee repeated several times, reminding one strongly of the 

 stridulation of Orchelimum minor.

The type of this recently described genus and species, taken at El 

 Portal, August 30, is contained in the collection. 



The original association of the genus with Zacycloptera Caudell 

 is correct, although the number of apical spurs on the caudal tibiae 

 was there stated in a way liable to confuse, the number of one side 

 of the tibiae or of pairs being given and not the total for the limb. 

 Aiioplodusa arizonensis (Rehn).
