RHAGOVELIA. 137 
is a little stouter than in R.armata. A. angustipes, Uhler, from the island of Grenada, 
is an allied form, but it has more slender hind femora. It is possible that &. distincta 
may prove to be referable to R. obesa, Uhler, but the description of the latter is too 
incomplete for identification. Orizaba specimens are figured, showing the different 
forms. 
6. Rhagovelia spinigera, n. sp. (Tab. VIII. figg. 28,9; 284, profile of 
pronotum.) 
Winged form. 2. Moderately elongate, brownish-black, the legs with a bluish-green lustre, the base of the 
antenne, a transverse mark on each side of the disc of the pronotum before the apex, the prosternum in 
great part, all the coxe and trochanters, the anterior femora broadly at the base, the ante-coxal portions 
of the meso- and metasternum, the connexival margins, and the apex of the venter, flavous; the pleura 
and sides of the abdomen bluish-grey; the elytra (the nervures included) blackish-brown; the head and 
pronotum microscopically pubescent, the pronotum greyish-pruinose at the sides in front, and clothed 
laterally with a few bristly hairs, the sides of the body sparsely pubescent, the sixth and genital segments 
fringed laterally with bristly hairs; antenne and legs finely pubescent, the femora, tibice, and the two 
basal joints of the antennz also with long scattered sete. Head with a smooth impressed median line; 
antenns moderately long, joint 1 nearly twice as long as 2, 2 and 3 subequal, 4 shorter than 3, fusiform, 
pointed at the tip. Pronotum produced behind into a long, semierect, spiniform process, the surface 
thickly punctured, except along the slightly raised median line, each puncture placed in a small rounded 
depression. Elytra extending beyond the genital segments, the nervures not very prominent, Legs 
comparatively slender, the hind pair rather short; anterior femora feebly sinuous; intermediate femora 
curved in front and concave within, abruptly compressed at the middle; posterior femora curved in front, 
concave on the inner side from the base to near the middle and also before the apex, scarcely stouter 
than the intermediate pair, and armed with a long curved tooth at the middle, and five or six short teeth 
between this and the apex, these latter diminishing in length outwards ; posterior tibise straight, obsoletely 
denticulate towards the base, and with a very short straight tooth at the apical angle; intermediate tarsi 
with joint 2 shorter than 3. 
Length 44, breadth (of the pronotum) 15 millim. 
Hab, Guatemata, San Gerénimo in Vera Paz (Champion). 
One example. In this species the intermediate femora look as if they had been 
injured during the earlier stages of the insect; but as the constriction is precisely 
similar in both legs, this cannot be the case. The hind femora, too, are abnormal in 
form, being hollowed on the inner face towards the base and apex, appearing bisinuate 
within. The pronotum is conspicuously punctured. 
7. Rhagovelia tenuipes, n.sp. (Tab. VIII. figg. 29, winged ¢ ; 30, apterous 9 .) 
Winged form. Moderately clongate, black, the legs with an seneous lustre, the base of the antenne pale flavous, 
the pronotum with a narrow fulvous transverse mark in front, the anterior and hind coxe and trochanters 
more or less flavous; the pleura and under surface bluish-grey; the body, legs, and antenne clothed with 
very fine brownish pubescence, and also (the apical two joints of the antenne excepted) with a few long, 
scattered sete. Head with a smooth impressed median line; antennz long and slender, joint 1 nearly 
twice as long as 2, 2 and 3 equal in length, 4 considerably shorter than 3, curved, pointed at the tip. 
Pronotum with the posterior portion obtuse behind, the surface with very fine scattered punctures. Elytra 
extending to far beyond the apex of the abdomen, the neuration irregular. Abdomen short. Legs very 
long and slender, the hind tibie unarmed at the tip; intermediate tarsi with joint 2 considerably longer 
than 3.
