tensive coloration fusing, so that in this region there is a dark medio-longitu- 

 dinal band. In the darker specimens, the dark bars of the caudal femora 

 are much less conspicuous and indeed are obsolete in a few of these. 



The markings of the pronotal disk and darker general coloration show clost'r 

 agreement with the type of jnodcstus vindcstiis. The present material, like 

 that of itwdcMiis aristus, however, differs from that race in the red of the 

 distal ix)rtions of the caudal tibiae anfl the vent ro-proximal portion of the 

 internal faces of the caudal femora.

Not only was this insect often found al)undant in the cat- 

 claw and other thorny shrubs, in the semi-desert areas of Trans- 

 Pecos Texas, but it was also seen frequently to seek shelter in 

 the sotols (Dasylirion sp.). It was found at elevations from 

 2800 to 6250 feet, but was never met with in any numbers above 

 the 5000 foot l(>vel in either the Chisos or Davis Mountains. 

 Conalcaea coyoterae" new species (Plate III, figs. 1, 2 and 3.) 



This insect is related to C. huachucnna Rehn. It asrec.^ 

 closely in all features except that in inost of the specimens ])e- 

 fore us the caudal femora are not conspicuoui^ly Iticolored', the 



'The Coj'otero Apaches, "Wolf-Men", inhabited the region from which 

 the present species is known. 



'• In a single male, from Bill Williams ISIountain, the coloration of the 

 caudal femora is exactly as in hnachiicana. It would ajipear that no feature 

 of C()k)ration is of sufficient constancy', over tiie range of these species, to 

 warrant its use as an unciualified diagnostic criterion.
