Distal half of posterior surface of maxilla covered with hairs intermixed with stout spines; coxa of 1st leg furnished above the suture with a set of modified, plumose or simple bristles surmounted by a fringe of plumose hairs ; a similar fringe upon the trochanter protecting a set of scattered or definitely arranged notes ; posterior sternal sigilla subcen-tral; legs at most spined at the tips of the tibia? and protarsi; claws untoothed; male (?Eumenophorus) without tibial spurs or with but one. Subfamily EU.MENOPIIOUINJE. «'. Thoracic fovea forming a transversely elongate pit (see under a0, ba on p. 746). Moncentropus and Anoploscelus. b'. Thoracic fovea forming a crescentically procurved groove (see under b1 on p. 746). Eumenophorus, Hysterocrates, Phoneyusa. b. Distal end of posterior surface of maxilla mesially naked, striate, neither spinous nor hairy ; no feathery fringe on upper side of coxa or trochanter of first leg, the area of the coxa above the suture furnished with simple or spiniform hairs (claws toothed, 4th tarsus divided by band of setag, not always very distinct in Scodra). a2. Legs without spines, copiously hairy, ocular tubercle low, wide (thoracic fovea shallow, transverse, &c.) Scodra. b2. Tibiae and protarsi, especially of posterior legs, strongly spined ; legs normally hairy; ocular tubercle convex; eyes compact. «3. Thoracic fovea crescentically procurved ; sternal sigilla submarginal; anterior tibia of male without spurs Selen ogyrus. b3. Thoracic fovea straight, transverse; sternal sigilla removed from the margin ; anterior tibia of male unarmed Miaschistopus. B. I. P.] EXPLANATION OF THE PLATES. PLATE XLI. Fig. 1.
