316 THE CANADIAN ENTOMOLOGIST. 



Eggs red; eggs in body of ° contained well-developed larvae, and are 

 about 336 \x long and 180 broad. 



Hab. — Roswell, N. M., on a low grass in an alkaline spot, abundant 

 on the leaves and stems, Aug. 24, 1902. I believe this is a distinct 

 species, but it is so close to P. Neomexicatius ( Dactylopius Kingii 

 Neomexicanus. Tinsley, 189S) that no harm will be done by treating it 

 as a variety for the present. It has a Chalcidid parasite, a species with 

 very pale legs, and the apical portion of the antennae white, the basal part 

 black. 



Two other species allied to the present one are Pseudococcus 

 roseotinctus ( Dacty/oJ>ius roseoii/ictus, T. & W. Ckll.) and /'. salinus 

 ( D. sali/ius, Ckll.). All these form a little group with a characteristic 

 type of antenna, different from that of the Eastern mealy-bugs. 



NOTES ON SOME GENERIC NAMES EMPEOYEU BY SER- 



VILEE, IN THE REVUE METHODIQUE, AND FIEBER, 



IN THE SYNOPSIS DU EUROPAISCHEN 



ORTHOPTERAN. 



BY JAMES A. G. REHN, PHILADELPHIA, PA. 



As has been shown by several previous writers, the Synopsis 

 published in instalments by Fieber, in Lotos, Volume III., all appeared 

 on or before August, 1S53. Such being the case, all his new generic 

 names have precedence over those of L. H. Fischer,* the preface of 

 whose work bears the date, November, 1853, and which is unlikely 

 to have appeared before 1854.

 Blepharis, Serville. Ibid., p. 47. 



As this name is preoccupied by Blepharis, Cuvier (Regn. Anim., II., 

 p. 322, 181 7), I propose Blepharopsis in its place.
