234 THE AMERICAN MUSEUM JOURNAL infant paralysis may spread by direct contact between human beings or in other ways than by fly bites. On the other hand it seems certain that the biting stable fly is one means by which this disease is conveyed; and the seasonal and geographical prevalence of the epidemics makes it seem prob- able that this is the usual and most important means. The Stomoxys calcitrans like the house fly or filth fly (Musca domestica) is a two-winged fly of the family Musci- dse. It closely re- sembles the house fly in general form and size and may easily be mistaken for it by the casual observer. It differs from the house fly in one very impor- tant respect how- ever, in the posses- sion of a sharp biting proboscis instead of the soft tongue-like mouth parts with which the house fly absorbs its food. This proboscis of the Stomoxys may be seen projecting for- ward as a fine black beak when the insect is at rest. Another important difference lies in the venation of the wings, the third of the long veins being bent at a less sharp angle in the Stomoxys than in the house fly. Two additional points of difference between the house fly and the stable fly are brought out in Mr. Matausch's original drawing reproduced herewith: that the posterior edge of the compound eye as seen in side view is concave in Stomoxys calcitrans and practically straight in Musca domestica; and the antennae of Stomoxys calcitrans are clothed with hairs on the upper side only while those of Musca domestica have hairs both above and below.

Mr. Ignaz Matausch, preparator, who has recently completed a marvelous piece of technical work in the shape of an enlarged model of the common house fly. It represents a magnification of 64,000 diameters, required one year for its construction and is the most accurate representation of this insect in existence
