NO. 1124. REVISION OF THE MELANOPLI SC UDDER. 25 



especially above, the punctation extending upon the sides of the fas- 

 tigium; rest of face and lower part of genae sparsely punctate; anten- 

 nae fuscous, apically ferruginous. Pronotum with the disk of the 

 prozona more uniformly darker than the rest, the lower part of the lat- 

 eral lobes of the prozona suffused with luteous; thoracic epimera black. 

 Tegmina narrow at the base, enlarging rather rapidly to beyond the 

 middle and then again diminishing to the well-rounded extremity, dis- 

 tinctly shorter than the pronotum but longer than the prozona, black 

 in the interstices of the veins which are fusco-luteous, generally darker 

 below than above. Hind femora variable in color but with the upper 

 half or more of the outer face always dark fuscous, sometimes black- 

 ish, the rest of it more or less luteous, the adjoining carinae black, but 

 the others yellowish, the outer portion of the lower surface dull oliva- 

 ceous, the upper surface olivaceo-fuscous, the geuicular arc black ; hind 

 tibiae red, feebly incurved, the spines black on their apical half, more 

 or less pallid, especially on the inner side, on their basal half. Abdo- 

 men sparsely and coarsely pundate throughout with a pallid median 

 carina, the hinder edges of the segments sometimes deeply infuscated. 

 Supraanal plate of male rather long triangular, with a pair of approx- 

 imate, rather sharp ridges, subparallel but nearly meeting in the middle, 

 inclosing on basal half a tolerably deep sulcus, just before the extrem- 

 ity of which, outside the middle of either side of the plate, is a very 

 short blunt ridge; furcula consisting of a pair of subattingent minute 

 lobes, projecting by about their own width ; cerci compressed, laminate, 

 broad, subequal, tapering a very little at the base, subfalcate, the lower 

 apical portion produced and very acutely angulate, not incurved ; apical 

 tubercle coarse and blunt, projecting beyond the apical margin of the 

 subgenital plate but a short distance. 



Length of body, male, 19 mm., female, 27 mm.; antennae, male, 

 female, 9 mm.; tegmina, male, 4.1 mm., female, 5 mm.; hind femora, 

 male, 12.5 mm., female, 15 mm. 



Two males, 3 females. Sierra de San Miguelito, San Luis Potosi,

2. CONALCAEA TRUNCATIPENNIS, new species. 



Fusco-testaceous, mottled with dull ferruginous, the abdomen dull 

 testaceous. Head pale ferrugineo-testaceous, mottled with ferruginous 

 on luteo-testaceous, the summit with two divergent ferruginous stripes 

 and feeble signs of a postocular ferruginous stripe; fastigiuiu feebly 

 depressed between the eyes, punctate at tip ; frontal costa punctate 

 throughout, very shallowly sulcate , rest of face and lower part of genae 

 sparsely punctate; antennae dark fuscous. Pronotum with feeble signs 

 of a luteous stripe following the lateral carinae, the posterior margin 

 of either side, including that of the lateral lobes, sinuate. Tegmina 

 rapidly enlarging from the constricted base to the middle, beyond sub- 

 equal, broadly truncate at the extremity, about as long as the prozona, 

 testaceous. Hind femora ferrugineo-testaceous, dull olivaceous beneath,
