228 ENTOMOLOGICAL NEWS. [May, 'l2 



will be published in the Zoologischer Anzeiger. If the majority favors 

 the first of these propositions, the matter will be brought before the 

 Halle meeting of the Society, May 27-30, 1912, and put in execution as 

 far as possible. 



Prof. F. E. Schulze proposes to submit a proposition to the Inter- 

 national Nomenclature Commission to be reported to the International 

 Zoological Congress of 1913 to the effect that since some zoologists 

 wish no alteration of long-used generic names, while others prefer the 

 oldest available names, both parties can be met for the present by 

 writing first the oldest justifiable generic name, followed by the long- 

 used later name preceded by the sign of equality and enclosed in 

 parentheses, thus: Sphenodon (Hatleria) ; Fasciola ( = Distomum) 

 hepatica; Molge ( = Triton~) alpestris. (Zoo/. Anzeig, Feb. 27, 1912.) 



This procedure, according to R. Hartmeyer (/. c., p. 336) has been 

 used for several years by specialists in the Ascidiae, except that square 

 brackets without the sign of equality have been used instead of the 

 parentheses, etc., in order to avoid confusion with the use of a name 

 of lower taxonomic rank, as subgenus, e. g., in parentheses after a ge- 

 neric name. 



Prof. Fr. Dahl in an article on "The value of definitively established 

 Rules of Nomenclature" (in German) argues for the preservation of 

 the rules as adopted at the International Zoological Congress of Ber- 

 lin without any later modifications or exceptions. (Zoo/. Anzeig. Feb. 

 27, 1912, pp. 205-209.) 



A NEW GENERIC NAME FOR CALLOSAMIA CALLETA (WESTwooo). In 

 the course of preparing for the press the manuscript on Saturniidae 

 left by Dr. A. S. Packard, it has become evident that Callosamia call eta 

 stands quite apart from the typical members of the genus (prouiethea 

 and angulifera], and should surely form a distinct genus, to which 

 the name Eupackardla may be applied : type Eupackardia callcta 

 (Westwood). Dr. H. G. Dyar, to whom I am indebted for some ad- 

 vice in the matter, does not know of any other species which should 

 go with calleta. The calleta. moth differs in venation and markings 

 from Callosainia, as Dr. Packard's manuscript fully indicates; but 

 more especially the species differs in the larva, the characters being 

 described by Packard in Proc. American Acad., xxxix (1904), pp. 

 547-551, and beautifully illustrated by colored plates prepared for the 

 forthcoming volumes. T. D. A. COCKERELL. 



FOSSIL COCKROACHES FROM TEXAS. (ORTHOP.). In Publication 146 of 

 the Carnegie Institution of Washington, issued December 2Oth, 1911, 

 Professor E. H. Sellards has an interesting account of two new cock- 

 roaches, Etoblattina tc.vana and Etoblattina (?) robusta, from the 

 Permian of Texas. The specimens were obtained by Professor E. C. 

 Case, but unfortunately nothing is said of the exact locality. I am
