272 FAMILY VIII. — CORIZID^E. 



tellum yellow; membrane hyaline, sparsely mottled with fuscous dots; 

 costal edge of elytra alternated with yellow and fuscous; under surface 

 dull yellow, the sides of abdomen, a spot at base of sixth ventral and two 

 spots between front and middle coxa? fuscous; legs dull yellow, the apical 

 half of hind femora fuscous vaguely mottled with paler. Antennal 

 spines short, slightly divergent, not reaching basal third of first joint, 

 the latter surpassing apex of head by one-half its length. Beak reach- 

 ing middle of metasternum. Pronotum with humeri broadly rounded, 

 sides rather deeply concave, margins crenulate; disk with a fine slightly 

 raised smooth median line, elsewhere evenly not densely punctate. Scu- 

 tellum similarly punctate, its margins thickened, apex rounded. Length, 

 6 — 7 mm. ; width, 2 — 2.3 mm. 



Dunedin, Ft. Myers and Key West, Fla., Nov. 22 — April 1 ; 

 Orizaba, Mex., Aug. 2 (W.S.B.). Taken by sweeping vegeta- 

 tion along the borders of tidewater lagoons and in low moist 

 grounds. Recorded by Barber also from Biscayne Bay and Key 

 Largo, and known from Texas, the West Indies and Mexico. 

 This is the species determined by Van Duzee (1909, 161) as 

 affinis Dallas, but the original description is so short and un- 

 satisfactory that comparison with the type should be made. 

 Dallas states that the beak "vix ad basin pedum posticorum 

 attingenti," which is true of the species in hand, whereas he 

 says of his perpunctatus, a synonym of serratus, "rostro abdomi- 

 nis basin attingenti." In Gibson's key (1917a, 441) the reverse 

 of this is stated. 



200 (335). Harmostes serratus (Fabricius), 1794, 75. 



Form of affinis but longer. Above dull yellow, thickly marked with 

 reddish-brown punctures and sprinkled with reddish dots; membrane 

 longer with more distinct fuscous or reddish dots; under surface yellow 

 thickly sprinkled with small reddish dots and points; tarsi in part fus- 

 cous; color otherwise as in affinis. Basal joint of antennae but little sur- 

 passing apex of head, the spines at its base longer than in affinis; second 

 joint one-fourth or more shorter than third; beak reaching base of ab- 

 domen. Pronotum with humeri subacute, disk more strongly declivent 

 and more narrowed in front than in affinis, finely, densely punctate and 

 with a fine median line; side margins more deeply concave, their edge 

 serrulate. Scutellum with apex slightly narrower, its margin less 

 thickened. Length, 8 — 9 mm.; width, 2.3 — 2.5 mm. 



R. P. Park, Fla., Dec. 12 (W. S. B.) ; one swept from roadside 

 herbage. Brownsville, Tex., Aug. 2. {Gerhard). A neotropical 

 species recorded by Uhler as occurring in Arizona, Mexico, 

 California and Cuba, and by Van Duzee (1917, 117) only from 

 Texas and Florida. Gibson (1917a, 444) gives its range as 

 "Brazil, Argentina, Paraguay, West Indies, Central America 

 and practically the entire United States." The specimens at 

 hand are much paler than those of affinis from Florida.
