soletely denticulate within. Pronotal spine very long, stout, and raised, 

 armed with a strong tooth at the base beneath. 



"Length, 5 mm.; breadth (of the pronotum) 1% mm. 



"Apterous form. Male and female. Fusiform, the pronotum ab- 

 breviated and rounded behind; the abdomen metallic green above, with 

 a stripe of greyish pubescence running down each side of the dorsal 

 surface; the connexivum very broad in the females, extending inwards 

 and overlapping the dorsal surface of the abdomen, the two portions 

 nearly or quite meeting along the median line. 



"Var. Apterous form. Male and female. The anterior femora dark 

 to the base; the cox?e and trochanters darker, the latter, at most, flavous 

 at the base, the sixth ventral segment broadly flattened, the flattened

Description taken from Champion Biol. Cenlr. Am. Heter. 



"Winged .form. Male. Moderately elongate, brownish-black, the legs 

 with an geneous lustre, the base of the antennae, a transverse band on 

 the front of the pronotum, the prosternum, all the coxae and trochanters, 

 the basal half of the anterior femora, the hind femora at the base, 

 within, and beneath, the connexivum, the last three ventral segments 

 broadly in the middle, and the genital segments beneath, flavous or 

 fulvous; the pleura and sides of the abdomen bluish-gray; the elytra 

 blackish-brown, the nervures darker; the head and pronotum somewhat 

 thickly clothed with short yellowish pubescence, the head and propleura 

 with a few long bristly hairs; the costal margins of the elytra, the sides 

 of the body, the legs, and antennae pubescent, the two basal joints of the 

 antennae, the margins of the genital and sixth connexival segments, and 

 the legs clothed also with long scattered setae. Head with a smooth im- 

 pressed median line; antennae moderately elongate, joint 1 rather more 

 than one-half longer than 2, 2 and 3 subequal, 4 a little shorter than 3, 

 pointed at the tip. Pronotum produced behind into a long spiniform 

 process, which is armed with a stout spine beneath. Legs moderately 

 stout; anterior tibiae dilated in their outer half, grooved beneath; pos- 

 terior femora moderately incrassate, armed with a long tooth at the 

 middle, and with a row of short teeth extending thence to the apex, 

 these teeth diminishing in length outwards; posterior tibiae slightly 

 sinuate and finely denticulate within, straight on their outer edge, and 

 with intermediate tarsi with joints 2 and 3 subequal in length. Ventral 

 segments land 2 and the intercoxal portion of the metasternum depressed, 

 the two segTnents with indications of a m.edian ridge, the sixth ventral 

 segment feebly emarginate at the apex and depressed along the middle 

 behind. 



"Apterous form. Female. Fusiform, the pronotum abbreviated and 

 rounded behind; the posterior femora a little less incrassate, with the 

 first (or median) tooth longer and those near the apex shorter; pos- 

 terior tibia3 straight and finely denticulate on their inner edge. 



"Length, 5% mm.; breadth (of the pronotum of the winged male), 

 2 mm."

"Only the unwinged form is at present known. It is short and thick, 

 subconical posteriorly, bluish plumbeous, opaque, minutely hairy, with 

 the sides of the abdomen broadly reflexed. The head wide, convex, with 

 a slender black line on the front, the orbits of the eyes bordered with 

 yellow; the rostrum testaceous, reaching considerably behind the anterior
