The Entomologist's record and journal of variation . her variable in length but usually longer than those in part of lamina dorsalis spiculate, anterior to basal spines, scobin-ate. Lamina ventralis rather narrow but broader at the base, comprisedof a field of short, strong spines, latter stronger and larger at the baseand towards the centre. A portion of the vesica spiculate, cornuti hardlyevident. Vesical pad or Blase present. 9 genitalia. Schildchen very broad, triangular in shape. A slightdevelopment of the lamella postvaginalis, lamella antevaginalis ovoid,elongate. Ductus bursae weakly sclerotized on one side, anteriorly. Bursacopulatrix spherical, signum vestigial or absent. First pair of tibial spurs present or absent. Superficially, gallica may be distinguished from giesekingiana Reiss bythe narrower forewings and rather denser scaling. The middle forewingstreak is rarely broken in gallica and, when this does occur, is foundonly in aberrant specimens. THE SILVICOLA BURGEFF GROUP OF THE GENUS ZYGAENA FABRICIUS. 4 ENTOMOLOGISTS RECORD 15/1/1964 Z. gallica gallica Oberthiir Z. gallica Oberthiir, 1898, Bull. Soc. ent. Fr., p. 21. Type locality: Neighbourhood of Digne, Basses-Alpes, France, 1000 m. Material examined: Lectotype tf, 25 J rf, 3 9 9, Digne, Basses-Alpes. cJ genitalia. As above. The differences in the genitalia of gallica andgiesekingiana are slight and possibly do not justify their separation intotwo distinct species. The two lateral spines at the base of the laminadorsalis are more strongly developed in giesekingiana. 9 genitalia. Ductus bursae weakly sclerotized compared with that ingiesekingiana, signum vestigial or absent in gallica, vestigial in giese-kingiana. The genitalia of gallica are figured by Le Charles (1935:15) andAlberti (1958: 314). The latter author has placed gallica as a subspeciesof nevadensis Rambur but we see no justification for this. The genitaldifferences, although small, remain constant. The lamina dorsa
