NO. 1124. RE VISION OF THE MELANOPLISC UDDER. 299 



above the pronotum even in the male, the interspace between the eyes 

 rather narrow, scarcely wider than (male) or about half as wide again 

 as (female) the first antennal joint; fastigium rapidly declivent, silicate 

 throughout ; frontal costa percurrent, subequal, not contracted above, 

 as wide as the interspace between the eyes, snlcate at and below the 

 ocellus, biseriately sulcate above ; eyes pretty large, rather prominent, 

 much longer than the infraocular portion of the genae; antennae testa- 

 ceous, almost as long (male) or about two-thirds as long (female) as the 

 hind femora. Pronotum equal on the prozona, expanding a little and 

 gradually on the metazona, more in the female than in the male, the disk 

 feebly convex and passing by a strongly rounded shoulder (the shoulder 

 hardly noticeable on the prozona) into the vertical lateral lobes, which 

 have feeble and broken or no indications of a fuscous band on the 

 upper part of the prozona; median carina distinct on the metazona, 

 quite or almost wholly obsolete on the prozona; front margin faintly 

 convex, hind margin obtusangulate; prozoua quadrate in the male, 

 transverse or quadrate in the female, feebly emarginate in the middle 

 posteriorly, scarcely or no longer than the metazona. Prosternal spine 

 short, conical, blunt, erect; interspace between mesosternal lobes much 

 more than twice as long (male) or half as long again (female) as broad. 

 Tegniiua much surpassing the hind femora, exceptionally slender, 

 scarcely tapering, apically well rounded, testaceous with a mesial line of 

 exceedingly feeble and sparse fuscous spots; wings narrow and pointed, 

 hyaline with light testaceous veins and with scarcely perceptible 

 infumation at the extreme tip. Hind femora strongly compressed, the 

 outer face so flattened as hardly to show any convexity, testaceous,, 

 immaculate, the outer face sometimes feebly iufuscated, the genicular 

 arc fuscous; hind tibiae luteo-testaceous, the spines black on apical half, 

 ten to eleven, usually ten, in number in the outer series. Extremity 

 of male abdomen clavate, a little upturned, the supraanal plate long 

 triangular, rather strongly contracted just beyond the base, the lateral 

 margins narrowly elevated, the apex acutaugulate, the median sulcus 

 consisting of a basal triangular portion, beyond which it is interrupted 

 and again appears apically as a channel between two lateral bosses ; 

 furcula consisting of a pair of basally attingent, broad, flattened plates 

 which taper very rapidly and then are continued as cylindrical, parallel 

 needles, reaching at least two-thirds way across the supraanal plate; 

 cerci slender, mesially contracted, apically spatulate, compressed 

 laminae, as viewed laterally straight, as viewed from above apically 

 incurved and then feebly returning to their original direction at 

 extreme tip and there externally sulcate, the whole almost reaching 

 the tip of the supraanal plate, and the apex as broad as the base; 

 infracercal plates well rounded apically, slightly longer than the supra- 

 anal plate; subgenital plate much longer than broad, of moderate 

 breadth, a little broader basally than apically, the apical margin 

 slightly and gradually elevated, well rounded, entire. (The drawing 

 is made from a specimen somewhat distorted by preservation in spirits.)
