Excerpt: ... the mouth is developed in the Diptera nothing was known with regard to it. Weismann failed to detect the rudiments of the proboscis in the young nymph, and although Kiinckel d''Herculais speaks of the appendicular discs of the head, and actually figured them in the resting larva of Volucella, he gives but one figure in which I can recognise the position and relations of the maxillary discs [25, PI . 7, Fig. i,//], and in the description of the plate he refers to them as the rudiments of the antennae. He did not, therefore, recognise their real nature. I have already described the maxillae of the Blow-fly larva (page 37) and the stomal disc. It is from the hypodermis of the stomal disc that the disc at the extremity of the proboscis originates, and as the second pair of maxillae are easily seen in the embryo lying between and behind the first pair, on which the rudimentary stomal disc is apparent, it is plain that the terminal portion of the proboscis of the imago is developed from the first, and not from the second pair of maxillae. Robineau-Desvoidy is the only author who, so far as I know, arrived at conclusions which my researches enable me to endorse, but, unfortunately, he gives no reasons for his statements, which have received little attention. He says, ''The proboscis of the Diptera, in my opinion, is not formed by the lower lip, as in the Hymenoptera, but by the maxillae. In the Muscidae it is usually membranous, sometimes solid and triarticulate. The more or less solid piece which covers the groove on the dorsal surface of the proboscis is the labrum or upper lip'' [49, p. 12]. Desvoidy, however, says in the same paragraph, '' Its base is enveloped by the base of the labium, of Description Of Plate VI. One lateral half of the Proboscis of the Blow-fly divi...
