with cinctfpes, the present species is much larger and lacl^s the decided 

 dusky bands on the sides of the head ))ack of the e3'eS and on the pro- 

 notum, and the hind femora only bear traces of the fuscous bands 

 across their upper edge, while the hind tiljifi? are characterized b}" the 

 entire absence of any fuscous tinge. The tegmina of rohusta also 

 lack the decided conspersing of the species to which it has just been 

 compared. Its head is slightly narrower than the front edge of the 

 pronotum and the eyes less prominent, while the latter gradual!}' widens 

 from the front edge instead of only on the posterior lobe. The teg- 

 mina and wings do not quite reach the tips of the robust hind femora. 



General color uniform pale brownish testaceous, with a shade of olive 

 on sides of pronotum, pleura, and outer face of hind femora; head and 

 pronotum with a few scattered small dots of reddish brown; tegmina 

 also dimly marked with small pale brownish specks, especially in the 

 discal field and on dorsal edge of basal half; hind femora with their 

 lower edge dark plumbeous, and a series of five medium-sized blotches 

 of same color on lower outer carina, upper edge crossed l)}- two well- 

 defined, but not prominent, dusk}' bands, which cross over to the inner 

 face and fade away; antenna^ fuscous, darkest at apex; prosternal spine 

 rather long, coarse, and curved to the rear. 



Length of body, female, 83; of pronotum, T.T); of tegmina, 2:3; of 

 hind femora, 18.6 ram.

DICHROPLUS PARAGUAYENSIS, new species. 



Size medium, form elongate, but not especially slender. General 

 color uniform brownish testaceous or dull ferruginous with an oliva- 

 ceous tinge on head, sides of pronotum. and hind femora, most appar- 

 ent in the female, without indications of darker or lighter markings 

 save at the base of the tegmina, where there is a trace of black on the 

 median veins, and faint indications of dusky bands on upper edge of 

 hind femora. Middle of sides of pronotum also provided with the 

 usual piceous band, but very faintly. 



Body, legs, and even tegmina rather hirsute. Head a little Avider 

 than the front edge of the pronotum, the occiput slightly elevated above 

 the level of pronotal disk, vertex between the eyes nearly twice the 

 width of the first antennal joint, the fastigium depressed, broadly sul- 

 cate; frontal costa a trifie contra(;ted above, evenly widening below, 

 coarsely punctate above and sulcate at ocellus and below. Pronotum 

 with the anterior lobe cylindrical, a little longer than the posterior one, 

 which has the surface gently punctate and the hind margin a little 

 obtuse angled, the apex rounded. Tegmina of medium width, a little 

 surpassing the apex of both fcmoi-a and alKlomon. Hind femora rather
