Dec, 1903.] A Root — Infesting Fulgorid. 43 



As the life habits of related species of Mjnidus are unknown, it 

 seems quite possible that others may prove to be subterranean 

 and the rarity of these forms in collections readily accounted for 

 by this protected habit. 



What appears to be the larva or a pre-pupa stage has a length 

 of two and sixty hundredths mm. and a width of one mm. It is 

 pallid greenish, sutural lines appearing white, and the cottony 

 secretion of the posterior segment of the abdomen scant; the beak 

 extends just beyond the second coxae. The mature nymph or 

 pupa stage has a length of four mm., or, including the cottony 

 secretion, four and one-half mm. and a width of one three-tenths 

 mm. It is mostly of a pale yellow or whitish color ; some indi- 

 viduals appear more decidedly greenish and some dusky or dirt 

 color. There is a well marked median dorsal stripe and fainter 

 Imes laterally, marking the margins of the wing pads. The three 

 terminal segments with the projecting cottony filaments extend 

 one-third the length of the abdomen and when fully extended 

 appear as a wide tuft. The tuft, however, is easily shed and 

 when the abdomen is denuded only very narrow margins of white 

 thread appear around the terminal borders of the segments. The 

 surface of the thorax and abdomen is faintly dusky, contrasting 

 with the white sutural lines. The eyes are red. The body of the 

 segments are dusky with broad sutures yellow, a dusky patch on 

 the thorax and another on the posterior border of the hinder 

 wing pad. The legs are whitish, the beak reaches to the base 

 of the third coxae. 



The Imago is pallid yellowish green, the front above and on 

 lower border with black. Length, male, 3.5, mm , to tip of elytra 

 5 mm.; female, 4 mm., to tip of elytra, 5.5 mm. 



Head wider than long, vertex one and one-half times longer than wide, 

 tapering to apex which is broadly rounded, margins slightly raised, disk 

 slightly raised towards apex. Front much widened towards apex. Lateral 

 keels thin, broad, median keel weaker. Clypeus triangular, keels obtuse. 

 Pronotum short, posterior margin deeply concave. Posterior angles scarcely 

 rounded. Scutellum longer than head and pronotum together acutely 

 angled behind. Keels slightly divergent. Elytral nervures strong and set 

 with minute hairs, slightly setigerous 



Color greenish or pallid, the vertex unmarked, but the front bears the 

 black spots just beneath the apex of vertex and a band across its apex, 

 either yellowish or infuscated, in some specimens distinctly blackish. The 

 scutellum outside the lateral carinae, and in some cases in posterior portion 

 of intercarinal spaces infuscated, appearing as obscure longitudinal stripes. 

 Elytra hyaline with veins infuscated, a faint stigmal and post-claval spot and 

 the apical portion of whole elytron sometimes slightly smoky. Ovipositor 

 of female black. 



Male pygofers nearly truncate, a minutemedian process, the styles broadly 

 expanded apically, curving outward but their inner borders touching.
