36 Psyche [March
Scudder2 in which one pair of wings is yellow and the other black. He describes this as a hermaphrodite-really a gynandromorph-while the specimen from Allenton is a normal female with the normal female coloration of both forms and with her abdomen distended with eggs. Knowing nothing of its antecedents, it is idle to speculate as to the genetic status of this specimen. It probably rep- resents a case of imperfect dominance, but whether this appeared as a mutation is, of course, impossible to say. There is a valuable problem for geneticists. DENDROIDES CANADENSIS LATREILLE-
SYNONYMY
BY H. S. BARBER
U. S. National Museum, Washington, D. C. Those rejecting the adoption in LeConte 1855 of Den- droides canadensis Latreille 1810 with bicolor Newman 1837 in synonymy as the proper name of our commonest Pyrochroid beetle probably did not realize that Latreille's designation (p. 430) of the type species for his monobasic genus erected in the same work (p. 212) connected his new specific name, canadensis, with the diagnosis, thereby mak- ing LeConte's use of the name the only proper choice under the International Code of Nomenclature. The misstate- ments in Lacordaire 1859 evidently led to the synonymy wrongly adopted in Gemminger and Harold 1870, this synonymy being followed by European workers and ac- cepted in Leng 1920. The current synonymy should be reversed and we should go back to the usage reflected in the catalogues by Melsheimer 1853, LeConte 1866, Crotch 1874, and Henshaw 1885, as well as in numerous more local lists prior to 1920. In the admirably brief but im- portant statement by Miss Payne 1931, recording her six years' observations on larvae which could not pupate except as stimulated by a particular food, her use of the name Scudder, S.

A WIREWORM DOUBLE MONSTER (LIMONIUS
CANUS LEG., ELATERID=, COLEOPTERA)
BY CHAS. E. WOODWORTH

Quite recently it was my good fortune to find and pre- serve an interesting monstrosity among some newly hatched wireworm larvae. In the course of examining about eighteen thousand of these, only one abnormal in- dividual was noted. Besides the great scarcity of anomalies in this group the fact that wireworms are of subterranean
