NO. 2041, THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 623 



pronotum, tip of scutellum, frontal carinse, coiinexiviim, femora 

 (mostly) and antenn83 light brown; frons dark between carinae, 

 often lighter on a discal streak; tibige lineated with brown. 



Head as broad as prothorax, produced before eyes, strongly 

 carinate; vertex straight behind, liind margin anterior to midpoint of 

 eyes; frons fully twice as long as broad, broadest at ocelU, somewhat 

 hexagonal, strongly carinate; antenuEe short, not reacliing to clypeus, 

 I haK as long as II. Pronotum rather long, with a foveal impression 

 on each side of median carina. Elytra long, hyahne, sometimes 

 faintly fumate, apical margin shghtly darkened. Legs rather 

 short; hind tibiae shghtly longer than short femora; calcar broad, 

 nearly as long as basal tarsus, margin with a double row of teeth. 



Male pygofers moderately long, aperture broad, transversely ovoid; 

 styles rather long, approximate at base, divergent in apical two- 

 thirds, broadened and square at tip, produced more outwardly than 

 in; anal tube short, mostly covered by anal tergite, with two slender 

 teeth on ventral margin. 



Described from two males (one brachchypterous) and eight fe- 

 males (three brachchypterous) from Massachusetts.

MEGAMELUS TERMINALIS Van Duzee. 

 Plate 48, figs. F, K. 

 Lihurnia terminalis Van Duzee '07:49. 



Average length 2.5 mm.; width of vertex 0.18; width of frons 0.22; 

 antennae, I, 0.11, II, 0.22. General color hght yellowish brown to 

 brown, abdomen almost black except connexivum and preanal 

 tergite white; dorsum hght; frons brown between carinse; antennse 

 brown, black at base of II and tip of I; legs Hght; elytra subhyaline, 

 shghtly browned. Body moderately large. 



Head short, narrower than pro thorax; vertex small, rather square, 

 narrow; frons long, narrow, more than twice as long as broad, sides 

 constricted a httle between eyes, below subparallel, carinas distinct. 

 Antennae reaching a httle more than to clypeus, I fully or over half 

 as long as II, sometimes three-fourths. Pronotum moderately 

 long, dorsal carinas not prominent. Legs moderately long, hind 

 tibiae longer than femora; calcar rather long, margin finely dentate. 



Male pygofers rather long, produced caudad on each side of anal 

 tube, as in M. erecta, but apex somewhat bifurcate, bifurcation more 

 or less variable in extent; styles short, stout, ligulate, not divergent 

 or scarcely so, blunt at apex; relative size of styles somewhat variable. 



Described from 30 males and females from San Marcos, Nicaragua 

 (Baker). It is possible that this is not identical with Van Duzee's 

 West Indian species.
