 Entomological Society of Philadelphia. The type of Ursula var. 

 texana Cresson is in the collection of the American Entomological

Distribution. — Texas. 



SPECIMENS EXAMINED 



Texas: Male, Austin (W. M. Wheeler) ; male, Goliad County, June 4, 1906 

 (C. B. Jones) ; 2 males, Brewster County, June 13-17, 1908 (Mitcliell & 

 Cushman). 



Cresson's var. texarm appears to be identical with Blake's chiron^ 

 both presenting all the characteristics of ursula Cresson except the 

 color of pubescence of the head and thorax. ChiroTi has the pubes- 

 cence of the head and thorax black. Since the name ''''chiron'''' has 

 priority it should replace texana as the varietal name. The genitalia 

 are identical with those of lepeletierii Fox.
