The response of the blowfly Phormia regina to stimulation by alcohols in the vapor phase has been investigated by means of an olfactometer which permitted quantitative control of stimulus concentration. The median rejection threshold was selected as a criterion of response. As was true in the case of contact chemoreception, the distribution of thresholds in the fly population is normal with respect to the logarithm of concentration. In terms of molar concentration the alcohols are rejected at logarithmically decreasing concentration as chain length is increased. Beyond decanol there is no further stimulation. When thresholds are expressed as pressures and plotted against saturated vapor pressures on logarithmic coordinates, the data fit a line the slope of which is not significantly different from 1; i.e., the thresholds vary directly with vapor pressure. Individual threshold values, however, deviate significantly from this line. and the deviation must be ascribed to other factors which have not as yet been identified. When thresholds are expressed as activities, all alcohols are equally stimulating. It appears that the limiting process of olfaction, at least in so far as the normal alcohols are concerned, may involve an equilibrium process. Conformity to this concept is most exact for intermediate members of the series.

The Eleticinae are an archaic and in many respects primitive group of Meloidae found in South America (widespread), Africa (south of the Sahara Desert), and the Oriental Region (India to Thailand). They are, in general, poorly represented in collections, and very little is known definitely of their bionomics. On the basis of an analysis of adult anatomical characters the subfamily is defined in detail and is classified to the generic level in the present paper. Two tribes, seven subtribes, and 10 genera are recognized, keyed, and diagnosed. The tribe Spasticini is arranged as follows: Protomeloina Abdullah, transferred from the Meloinae and reduced to subtribal rank, with Protomeloe Abdullah; Spasticina Kaszab with Spastica Lacordaire; Xenospastina, new subtribe, with Xenospasta, new genus; and Anthicoxenina, new subtribe, with Anthicoxenus Fairmaire and Germain, formerly placed in the Anthicidae, and Iselma Haag-Rutenberg. The arrangement of the tribe Eleticini is: Eospastina, new subtribe, with Eospasta, new genus, and Serrospasta, new genus; Eleticina Wellman with Eletica Lacordaire (and including, as subgenera, Sibuteletica Pic, Meteletica Kaszab, and Proeletica Kaszab); and Ertlianina, new name for Ertliini Kaszab, with Ertliana Selander (= Steniselma Borchmann, new synonymy) and Ceriselma Borchmann, the latter elevated from subgeneric rank in Iselma. Species described as new are Protomeloe simplex (Argentina), Spastica minas (Brazil), Xenospasta flava (Colombia), and Serrospasta vittata (Colombia).

Some Humidity and Light Reactions of the Granary Weevil,Sitophilus granarius(L.) (Coleoptera: Curculionidae)

The behaviour to moisture of a number of stored-product insects; Tenebrio molitor (Pielou and Gunn, 1940), Ptinus tectus (Bentley, 1944), Tribolium castaneum (Willis and Roth, 1950) and Tribolium confusum (Roth and Willis, 1951) have been studied. All these species live in a dry environment in flour and all have shown a preference for the drier of any two humidity alternatives. The moisture reactions of the granary weevil were studied since this species develops in a relatively moist environment (Richards, 1947) and should show a contrast to the reactions of the above species. The supplementary studies of this investigation were to determine the effect of moisture conditioning on the moisture reactions and to study the interaction between light and moisture.
