The individuals of P . fenestralis fenestralis measured above are average speci- 

 mens from fair-sized series. 



In addition to the type and allotype we have before us the 

 specimens measured above, which are: an additional female from 

 Katherine, Texas, bearing the same data as the type and allotype ; 

 a pair from Galveston, Galveston County, Texas, taken July 19 

 to 21, 1912, (Hebard; sandy spots back from beach), and a single 

 female from between Alice and Brownsville, Texas, taken in July. 

 With the exception of the latter specimen, which is from the 

 collection of the Brooklyn Institute of Arts and Sciences, the 

 series is contained in the Philadelphia collections. These addi- 

 tional specimens are considered paratypes. A series of two 

 males and three females taken in Hearne, Robertson County, 

 Texas, August 14 to 15, 1915, (Hebard; in moderate numbers on 

 sandy area near woods), contained in the Philadelphia collections, 

 is virtually intermediate between P. fen. fenestralis and P. fen. 

 frater in the structural differential characters. 



The Caeruleipennis Group of the Genus Anconia 

 The genus Anconia is made up of two groups, one centering 

 about A. Integra, the genotype, and the other composed of A. 

 caeruleipennis Bruner and the new species here described. Brun- 

 er's caeruleipennis-^ is known only from the unique female type, 

 which is now before us. In 1909, Rehn and Hebard referred 

 material taken in the vicinity of El Paso, Texas, to caeruleipennis, 

 having at that time only the brief description of the latter with 

 which to work. With the type in hand we can now definitely 



^^ Abdomen unnaturally extended, the measurement probably ten per cent 

 in excess of repose length.
