SPECIMENS EXAMINED 



CoLOBADo: Female, Fremont County. 



Texas : 4 females, 21 males, Juno, July 3, 1917, female. 



Dugesii is closely related to both foxi and phoenix. The female is 

 almost identical with them in form and sculpture but differs very 

 materially in the color and pattern of the pubescence. The male is 

 indistinguishable from the male of 'phoenix. The genitalia are alike 

 and the color of the pubescence is the same, except that in dugesii 

 there is a tendency for the pubescence of the pronotum to be tinged 

 with reddish. There is little question that the male placed here is 

 the male of dugesii since it shows the same close relationship to the 

 male of phoenix and foxi as the female of dugesii shows to the same 

 two species, and in addition the 21 males and 4 females were col- 

 lected at Juno, Texas, on the same date. At the present time the 

 male of dugesii can only be separated from the male of phoenix on 

 the basis of geographical data.

Females with the thorax pyriform, longer than broad, scutellar 

 scale absent, head as broad as the thorax, pygidium longitudinally
