NO. 1124. REVISION OF THE MELAXOPLISCrDDER. 345 



above the pronotum, the interspace between the eyes scarcely wider 

 than (male) or fully half as wide again as (female) the basal antennal 

 joint; fastigium steeply declivent, plane, with well elevated and 

 rounded lateral margins; frontal costa just failing to reach the clypeus, 

 subequal, fully as broad as the interspace between the eyes, sulcate at 

 and below the ocellus, biseriately punctate above; eyes of moderate 

 size, not prominent, shorter than the infraocular portion of the genae; 

 antennae ferruginous, feebly infuscated apically, nearly five-sixths 

 (male) or less than three-fourths (female) as long as the hind femora. 

 Pronotum subequal, feebly and gradually enlarging posteriorly, the 

 disk nearly plane, passing by distinct but abruptly rounded shoulders 

 forming subobsolete lateral carinae into the vertical lateral lobes, which 

 have only an obscure, rarely a distinct, dark postocular band, always 

 limited to the prozoua; median carina percurrent but blunt and a little 

 obscure on the prozona; front border subtruncate, hind border obtus- 

 angulate, the angle well rounded; prozona slightly longitudinal (male) 

 or quadrate (female), distinctly (male) or not (female) longer than the 

 closely punctate metazona. Prosternal spine short, conical, blunt, erect, 

 in the female a little appressed; interspace between mesosternal lobes 

 a little longer than broad (male) or transverse, but distinctly narrower 

 than the lobes (female). Tegmina reaching or a little surpassing the 

 tipsW the hind femora, moderately narrow, very gently tapering, 

 brownish fuscous, scarcely or distinctly though feebly maculate in the 

 proximal part of the discoidal area; wings moderately broad, hyaline, 

 most of the veins fuscous. Fore and middle femora tumescent in the 

 male; hind femora long and slender, luteo- testaceous, above rather 

 broadly bifasciate with blackish fuscous, often confluent along the 

 middle of the outer face and then more or less suffusing the whole face 

 excepting below, which with the under surface is dull luteous, occasion- 

 ally tinged more or less distinctly with orange, the sides of the genic- 

 ulation almost wholly fuscous; hind tibiae red, rarely with a very nar- 

 row, basal, fuscous annulus, the apical half of the spines black, ten to 

 twelve in number in the outer series. Extremity of male abdomen 

 clavate, somewhat recurved, the supraanal plate triangular with slightly 

 angulate sides, feebly acutangulate tip, and a large, equal, and deep 

 median sulcus extending over the basal three-fourths of the plate, 

 bounded by high and sharp ridges, buttressed in the middle of the 

 plate by slight transverse ridges; furcula consisting of a pair of dis- 

 tant slight denticulations lying on the outer side of the base of the 

 submedian ridges of the supraanal plate; cerci consisting of a straight 

 basal piece, gently and slightly tapering, less than twice as long as the 

 basal breadth, and a bifurcate apical portion, the bifurcation at right 

 angles, each fork bearing a similar angular relation to the basal piece, 

 the lower fork slight and tapering, about as long as the breadth of the 

 basal piece, directed obliquely downward, the upper fork nearly as long 

 as and about half as broad as the basal piece, equal, apically well 

 rounded, directed obliquely upward and bent a very little inward;
