 nae short, slender. Thorax very convex transversely and longi- 

 tudinally; propleurites long and narrow. Wings membranous, more 

 or less hyahne, sometimes subopaque, oblong-oval or somewhat 

 rhomboid al.

SYNOPSIS OF SPECIES. 



a'. Entire body siirface including legs and wings speckled with brown or black dots 



and spots; vertex and pronotiim veiy finely punctate, or smooth; eyes scarcely 



recessive; genal cones one-half to five-sixths aa long as vertex . .nidifex Schwarz. 



a}. Body surface not speckled with brown or black spots or dots; vertex and notum 



coarsely punctate; eyes more recessive over propleurites. 



¥. Forewings conspicuously and coarsely rugose; body surface and legs orange to 



brown with numerous white spots; forceps of male not terminating in a long 



hook-like process rugipennis, new species. 



b^. Forewings not rugose, semihyaline, more or less maculated apically. Vertex 

 and notum very conspicuously vermiculo-pimctate or rvigose; forceps of male 

 terminating in a long hook-like process. 

 c'. Forewings oval or only very slightly rhomboidal; genal cones nearly as long 



as vertex ; forceps of male slender vermicu losus, new species. 



c^. Forewings distinctly more rhomboidal, more maculated ; genal cones one-half 

 as long as vertex, broad; forceps of male very stout and thick. 



propinquus, new species.

Figs. 38, 40, 281, 433. 



Euphalerus nidifex Schwarz '04: 153, 239. 



Length of body 1.9 mm; length of forewing 2.1; width of head 

 0.90. General color greenish white, speckled with brown or black 

 spots over entire surface, including legs and wings; antennse tipped 

 with black on each segment; wings maculated apically and covered 

 over entire surface with dots. 



Head deflexed, not as broad as thorax, finely punctate; vertex 

 scarcely arcuate on posterior margin, almost flat, slightly raised along 

 median line, rounded broadly on anterior margin, slightly emarginate 

 over front ocellus. Genal cones large, broad, very obtuse at apex, 

 varying in length from one-half to five-sixths as long as vertex, 

 divergent only in apical half, continuing plane of vertex. Antennse 

 short. 



Thorax broad, strongly arched, punctate, spotted. Pronotum 

 moderately long, flat on dorsal surface; praescutum shorter than 

 scutum. Wings subhyaline, except maculated apicaUy, covered 

 with dots on veins and membrane, about two and one-seventh times 

 as long as broad, broadly rounded at apex; first marginal cell larger 

 than second; pterostigma large. 



Genitalia. — Male. — Genital segment relatively large; forceps rather 

 small, slender, arched, acute at tip; anal valve longer, sides subparal-
