REVISION OF THE MELANOPLLSCUDDER. 41 



rounded acuminate at tip, fully twice as long as broad. Hind femora 

 flavo testaceous, the angulate incisures of the outer face rather broadly 

 fuscous ; hind tibiae flavous or flavo- testaceous, the spines black except- 

 ing their base. Supraanal plate of male short triangular, with feebly 

 convex sides, rectangulate apex, and with a pair of short, oblique, rather 

 prominent, rounded ridges before the middle of the basal half of either 

 side; furcula consisting of cylindrical, equal, blunt fingers fully a third 

 the length of the supraanal plate; cerci compressed laminate, rather 

 slender, narrowed in the middle by the arcuation of the upper margin, 

 bluntly rounded at tip, gently incurved throughout, and hardly so long 

 as the supraanal plate; apex of subgenital plate a little angulate, 

 extended no great distance beyond the supraanal plate. 



Length of body, male, 16.5 mm., female, 25 mm.; antennae, male, 9.25 

 mm.; tegmina, male, 3 mm., female, 4 mm.; hind femora, male, 11 mm., 

 female, 15 mm. 



One male, 1 female. Sinaloa, Mexico, collected by Koels; received

12. PARAIDEMONA, 



(rcapa, beside; Aiclemona, a genus of Melanopli.) 

 Paraidemona BRUNNEK (pars), Re"v. Syst. Orth. (1893), p. 145. 



Body compact, not slender, subcylindrical, a little compressed, slightly 

 enlarged at the metathorax, especially in the female, the abdomen of 

 the male feebly clepsydral, the apex tumescent and rounded, and some- 

 what recurved. Head not prominent, the vertex well rounded, the 

 eyes separated narrowly in the male, not widely in the female, rather 

 prominent, particularly in the male, and large, much larger than the 

 infraocular portion of the genae, subangulate above in the female; 

 antennae very much longer than head and pronotum together, especially 

 in the male. Pronotum truncate at both extremities, enlarging very 

 slightly posteriorly, more in the female than the male, with slight, per- 

 current, median carina, no lateral cariuae; prozona twice as long as 

 the metazona, both equally and somewhat similarly punctato rugulose, 

 the transverse sulci of the prozona lightly impressed, one of them 

 dividing the prozona in equal halves and percurrent. Prosternal spine 

 moderate, blunt, conical, erect; interval between mesosternal lobes of 

 male longer, sometimes much longer, than broad; of female (where 

 known) a little longer than broad; metasternal lobes narrowly attin- 

 gent. Apterous in both sexes. Fore and middle femora of male dis- 

 tinctly tumescent; hind femora not very long. Lateral margins of 

 subgenital plate straight from the base, which is not ampliate and is 

 concealed behind the preceding segment; cerci styliform, conical; fur- 

 cula consisting of a pair of parallel, attingent, cylindrical processes, 

 terminating bluntly. 



As here restricted, Pczoiettix pnnctatus Stal is the type. 



The genus is confined to Texas and northern Mexico, so far as known.
