The metathoracic tergite is represented by only a very narrow strip (Fig. 10, 72?) on each side of the thorax and to these strips is articulated the first abdominal tergite. The narrow supraepimeron (????) and supraepisternum lie anteriorly, the latter being sub- divided into a small basal sclerite called the proepisternum (????) of the metathorax (it should be called the infraepisternum) (epsi) and a prominent episternum proper (Epsi) carrying the metathoracic spiracle posteriorly. These two pairs of thoracic spiracles control gas exchange with the external environment. As the work of Vinogradskaya (1953, 1954, I960)* reveals, the relative dimensions of the spiracles are *For the structure of thoracic and abdominal spiracles, including Culiseta annu- lata mosquitoes, see also Hassan, 1950; for the neuromuscular mechanism of spiracu- lar operation, see Hoyle, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Maslov, A.
