and very slightly infumate on the lower half next the coloured base.

 tip black, armed below towards the apex with a few sharp black spines. 

 Fore and middle tarsi variegated above, the basal segment pallid with the 

 proximal end black, the second segment wholly black and the terminal 

 segment entirely pallid with the claws tipped with black. Posterior 

 femora slightly hoary on the outer face, very inconspicuously banded on 

 the apical third with fuscous. Inner face black with light crossbars on 

 the apical half, where the fuscous becomes eliminated. Genicular arcs 

 slightly marked with fuscous. Posterior tibiae and tarsi yellowish, the 

 former preapically infuscated below and armed above with moderately 

 stout spines, eight or nine in the outer series. Calcaria and spines black

4. ANCONIA INTEGRA, Sctldd. 



Anconia Integra, Scudd. Ann. Rept. Chief Eng., 1S76, 515 (1876). 



Two males, five females ; Phoenix; April 12 — September 29, 1900. 



This variable species was described from a single pair collected by 

 Dr. O. Loew in the Mojave Desert, Lower California. Since then it has 

 been reported from Death Valley, California. 



The colour of this species varies from an almost uniform greenish 

 yellow to very conspicuously spotted with fuscous on the head, thorax 

 and elytra. The posterior femora are usually distinctly bifasciate above 

 with black. The thorax is sometimes very conspicuously varied above 

 by four cream-coloured marks : two, almost approximate, on the anterior 

 part of the pronotum, and two, divergent and widely separated, on the 

 lateral borders of the metanotum. These markings fade somewhat in 

 drying. The lateral lobes of such marked specimens are pallid along the 

 lower borders and furnished near the middle, in front, with an oblong, 

 similarly coloured mark.
