AbstractAdult silkmoths captured in northwestern Ontario and tentatively identified as Hyalophora columbia (Smith) were found to resemble H. gloveri nokomis (Brodie) which occurs as far east as Winnipeg, Man. Habitat studies showed that the larvae of the northwestern Ontario moths are not strictly larch feeders as are the larvae of typical H. Columbia.The dorsal thoracic tubercle colour of typical fifth instar H. Columbia larvae is red. Matings between typical H. Columbia and H. cecropia (L.) have produced fifth instar larvae with only reddish-orange tubercles. However, matings of male moths from northwestern Ontario with H, cecropia females have produced fifth instar larvae with reddish-orange, light orange, or yellow dorsal thoracic tubercles. Further matings of northwestern Ontario males with H. euryalis (Boisd.) and typical H. Columbia females have established the presence in northwestern Ontario of a colour polymorphism of which the phenotypic colour components are red, reddish orange, and yellow.The fifth instar dorsal thoracic tubercle colour of H. gloveri nokomis larvae is yellow and it is proposed that the yellow tubercle colour of the northwestern Ontario larvae has originated from the influx of genes from the nearby H. gloveri nokomis population.The evidence presented in this paper points to the existence of an intergrade population between H. gloveri nokomis and H. columbia in northwestern Ontario.

A fifth instar larval colour polymorphism in H. Columbia from northwestern Ontario had been previously indicated indirectly from the progeny of interspecific matings. The polymorphism has been confirmed directly by a recent collection of larvae from the vicinity of Kenora, Ontario. Results from six different mating classes suggest that the dorsal thoracic tubercle colours are determined by a pair of codominant autosomal alleles such that TRTR produces a red colour, TRTy a reddish-orange colour, and TyTy a yellow colour. Epistatic interaction with abdominal tubercle determining factors is hypothesized to cause larvae with white instead of yellow abdominal tubercles to have dorsal thoracic tubercles that are pinkish red, pale pinkish red, and pale yellow.Key words: Hyalophora, tubercle colour, polymorphism.

Infundibulicybe macrospora, a new species, is described and illustrated from the Himalayan moist temperate forests of Pakistan. The new species can be differentiated from close allies by its reddish orange to light orange pileus, whitish lamellae and stipe, and larger and broader basidiospores. The new species is also supported by molecular phylogenetic analysis inferred from internal transcribed spacer (ITS) region.

The paper investigates cross-cultural differences across Russian regions using the methodology of G. Hofstede. First, it discusses the most common approaches in measuring culture and the application of the Hofstede methodology in subnational studies. It identifies the critical issues in measuring culture at the regional level and suggests several strategies to address them. Secondly, the paper introduces subregional data on individualism and uncertainty avoidance using a survey of students across 27 Russian universities. The data allow to establish geographical patterns of individualism in Russia. It is demonstrated that collectivism is most prevalent in the Volga region, while individualism characteristic becomes stronger towards the Far East. The findings are robust to the inclusion of various controls and different specifications of the regression model. Finally, the paper provides a discussion about the potential of applying the sociocultural approach in economics.

The presence of the body colour polymorphism in the tropical invasive pest giant African snail is reported for the first time from South India. Three different body colour polymorphs were recognised viz. grey, black and white. The grey body colour is the most common polymorph. The black and white colour polymorphs are found to be in almost equal proportions in the reported localities with the grey counterparts. The cytochrome oxidase subunit I (COI) sequences of the three colour polymorphs are found to be identical. The presence of the body colour polymorphism in south India may be attributed to the avian predation and other selection pressures.
