ISTote that this part-way surrounds the socket of the leg, and articu- lates with the lateral margin of the sternum beneath. Students at this time will carefully distinguish the difference between color markings and sutures proper. (Fig. 199, Z>.) Parapteron.—Just cepha- lad or in front of the meso- thoracic wing is a very small triangular sclerite, the parapteron. This sclerite is inconspicuous, and not readily discerned. Epimeron.— Extending from the base of the front wing to the socket of the mid- dle leg lies the epimeron of the mesothorax. (Fig. 199, c.) Make a drawing of the lat- eral aspect of the mesothorax. Ventral View.—Between the nicsothoracic legs, forming the ventral surface of the mesothorax, is a prominent quadrangular sclerite, nearly straight on the front margin, but on the median line of caudal margin there is a well-developed dovetailed structure, making a notch in this segment.
