THE SMOKY CEANE-FLY. 125 area extending from the pharyngeal foramen dorsally and posteriorly about one- third of the distance to the vertex. Mentnm (fig. 63, h) terminated by a median blunt lobe supported on each side by a smaller lobe and two partly fused lobes; a nonchitinized, transparent area extends from the pharyngeal foramen into the apex of this organ, this area separated from the foramen proper by a pair of posteriorly directed, blunt lobes of the gular region. Labruin bearing on its dorsal surface a pair of broad protuberances (fig. 63, 6) each surmounted exter- nally with a brush of fine hairs and internally with a rounded tubercle bearing 3 peculiarly formed bristles. Antenna? single jointed, cylindrical, about one- fourth as wide as long, situated above the mandibles; basal tubercle trun- cate, about one-half length of antenna?. Mandibles (fig. 63, /, g) stout, the crown concave and provided with 2 large external teeth and a smaller dorsal internal one. Maxillae (fig. 63, d) quadrate, each being provided with 2 ante- rior and 1 lateral tuft of hairs and a short truncate cylindrical palpus. Body integument attached to head capsule at a line passing around head directly behind mandibles. Thoracic and abdominal segments, except anal segment, without ex- ternal appendages or vestiture of any kind. Circum- stigmal tubercles armed on their inner borders with a row of very short spines supported by a row of fine hairs. THE PUPA. Pupa (fig. 64) cylindrical, slightly sinuate in profile, 19 mm. in length and 2 mm. in diameter. Cases con- taining wings, antennae, and legs free and lying ap- pressed to venter. General color yellowish brown, the head, wings, antenna?, legs, and thoracic respiratory tubes dark brown. A light yellow stripe bordered by a fuscous line on either side, situated directly ventral to the spiracles, extends from tip of wings to base of anal segment. The fuscous
