tibie strongly dilated and the hind tibie sinuous (as in R. crassipes) in the male, 
the connexival margins pale, &c.

Velia armata, Burm. Handb. der Ent. i. p. 212’. 
Rhagovelia armata, Sign. Bull. Soc. Ent. Fr. 1877, p. liv’. 
Winged form. g. Moderately elongate, brownish-black, the legs with an seneous lustre, the base of the 
antenne, a transverse band on the front of the pronotum, the prosternum, all the coxe 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-grey ; 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 
antennew pubescent, the two basal joints of the antenne, the margins of the genital and sixth connexival 
segments, and the legs clothed also with long scattered sete. Head with a smooth impressed median 
line ; antennze moderately elongate, joint 1 rather more than one-half longer than 2, 2 and 3 subequal, 
4 a little shorter than 8, pointed at the tip. Pronotum produced behind into a long spiniform process, 
which is armed with a stout: spine beneath. Legs moderately stout ; anterior tibie dilated in their outer 
half, grooved beneath; posterior 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 tibie slightly sinuate and finely denticulate within, straight on their outer edge, and with 
a short straight tooth at the inner apical angle; posterior trochanters obsoletely denticulate beneath ; 
intermediate tarsi with joints 2 and 3 subequal in length. Ventral segments 1 and 2 and the intercoxal 
portion of the metasternum depressed, the two segments with indications of a median ridge, the sixth 
ventral segment feebly emarginate at the apex and depressed along the middle behind. 
Apterous form. @. 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; posterior tibi 
straight and finely denticulate on their inner edge. 
Length 52, breadth (of the pronotum of the winged ¢ ) 2 millim. 
Hab. Mexico (Mus. Berol.1: 3; Mus. Vind. Ces., ex coll. Signoret?: 2). 
Burmeister’s diagnosis of this species is quite inadequate, and a fresh description is 
given from one of his types, a male, and from a second specimen ( 2 ) belonging to the 
Vienna Museum. RR. armata is perhaps nearest allied to BR. femoralis, differing from 
it in the more elongate body, the longer legs and antenne, the less incrassate posterior 
femora in the male, the hind tibiz without long teeth in this sex. The partly flavous 
posterior femora, the depressed base of the venter in the male, &c., separate it from 
R. distincta. The apterous female from the Signoret collection is figured *.
