straight or curved, posteriorly or dorsally directed, 

 lateral lobes; the hypandrium undivided or with a 

 medial groovelike fissure. Proctiger often large, long, 

 thrust out at an angle. Female terminalia composed 

 of two small, short, thin, dorso vent rally compressed, 

 adjacent, unmodified dorsal and ventral lobes.

Williston's species Damalis occidentalis from Mexico 

 is probably not a true Damalis; it may belong to 

 Bromleyus E. Hardy. Damalis divisus Walker 

 from Brazil also probably belongs elsewhere. 



Protodamalis, new subgenus 



FlGTJBE 1661 



Type of subgenus: Protodamalis elongatus, new 

 species. 



Some species of Damalis Fabricius have a long, 

 slender, and cylindrical or tubular abdomen and the 

 entire postmetacoxal part of the metasternum mem- 

 branous, in contrast to the fully chitinized arch present 

 in other species of the genus. The face is convex and 

 often quite convex, with dense, bushy, coarse pile. 

 Hind femur and tibia much elongate and 2 or more 

 times as long as the middle legs and both hind femur 

 and tibia swollen or less clavate apically. Scutellum 

 thick, disc flattened and without impressed rim. Male 

 terminalia closed. Length 11 to 16 mm. 



Head: The face is convex, often quite convex with 

 bushy, dense, coarse pile, and the whole surface some- 

 times coarsely pubescent. Proboscis short, stout, 

 swollen at base, arched to a ventral point at apex and 

 laterally compressed. Vertex wider than front and 

 postvertex and upper occiput strongly flared and exca- 

 vated. Antenna typical of Damalis; style thinned at 



535914— 61— pt. 1 5 



tip. Second palpal segment short, exceptionally stout 

 and robust. 



Thorax : The thorax is short ; the mesonotum densely 

 pollinose but only moderately high. Scutellum quite 

 thick, the basal half of disc flat, the surface pollinose 

 and the thick rim bears a few, long, upright, stiffened 

 hairs. Postmetacoxal part of metasternum membra- 

 nous. Halteres large and long, placed far to the rear of 

 hind coxa. 



Legs : The hind legs are exceptionally long and grad- 

 ually dilated toward the apex of femur and tibia. 

 Hind femur densely appressed, coarsely setate; near 

 the apex on the medial side are a few of these oblique 

 setae, which become spinous and arise from minute 

 tubercles. 



Wings : The wings are slender, nearly four times as , 

 long as wide. The anterior crossvein is oblique and 

 enters the discal cell at or beyond the apical fourth of 

 this cell. Medial crossvein nearly twice as long as 

 upper anterior intercalary vein. Second branch of the 

 medius and first branch of the cubitus fused for a con- 

 siderable distance. 



Abdomen: The abdomen is long and cylindrical, 

 pollinose with almost no pile. Male terminalia large ; 

 hypandrium dorsal, obtuse, hoodlike, turned downward. 

 Epandrium has long, curved arms, which turn upward 

 and is completely divided to the base. 



Protodamalis elongatus, new species 



Length 16 mm. Male. Head : The head is black in 

 ground color, densely obscured by coarse, appressed, 

 pale, brownish yellow micropubescence on the face, the 

 quite vertical short stump, the cheeks, and on a moder- 

 ately wide, occipital, ocular margin. On the greater 

 and interior portion of the occiput and the postvertex 

 the pubescence is much thinned and tends to be sepa- 

 rated from the occipital border by a bare stripe. Pro- 

 boscis brownish yellow on the lower half, somewhat 

 more reddish dorsally and at the apex. Ventral, occip- 

 ital pile yellowish white, the stiff, apical hairs brownish 

 black. Palpus pale yellow, with coarse, bristly yellow 

 hairs; 2 segments present. Pile of occiput, vertex, 

 front, and face brownish yellow, and there are 2 or 3 

 black hairs mixed in with the facial pile. Pile of face 

 copious, long, coarse or almost bristly, and covering 

 ahnost the whole face except for a narrow space beneath 

 the antenna. First antennal segment and the basal half 

 of the second segment reddish brown, the apex of the 

 second and the whole of the third segment very dark, 

 reddish sepia. Third segment and the reddish brown 

 style, which is pale brown at the apex, are shining. 



Thorax: Mesonotum black in ground color, the 

 humerus and all the upper half of the pleuron brown 

 and slightly reddish. Almost the whole of the thorax, 

 including the scutellum, densely covered with flat, 

 appressed, coarse, brownish yellow micropubescence 

 which becomes pale along the lateral margins of the 

 mesonotum and paler on the lower half of the pleuron. 

 Bristles absent but the coarse, scattered hairs, many of 

 which are rather long on the postmesopleuron, the meta-
