The caudal portion of the ganglion becomes thick soon after the connectives have entered. The cephalic lateral portion of the ganglion is connected with the supraesophageal above by two large connectives, but smaller than those from the 1st thoracic ganglion. These cephalic connectives or crura cere- bri are connected together a short distance away from the gan- glion bv a cross branch or 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 Entomological Society of America.
