CATALOGUE OF ORTHOPTEROUS INSECTS. 



serratis ; tibiis posticis supva nunc lobatis nunc integris ; 

 operculo vaginali longissimo, lanceolate, canaliformi. Long. 

 Corp. cum operc. 5" 10'"; anten. 5'"." The insect, in fact, 

 closely resembles my Plate XXV. fig. 9 ; the abdomen is, 

 however, considerably broader, the metathorax as well as 

 the legs rather shorter, and the middle femora have two or 

 three serrations on the uuder side. I do not understand 

 on what grounds Burmeister considers this as the female 

 of this species, there being, as it appears to me, no analogy 

 in the structure of the body or legs to warrant such a con- 

 jecture.

The unique male of this species in the National Collec- 

 tion is of a dull luteous colour, with slightly defined black- 

 ish markings ; the legs dirty brown, with paler annulations. 

 The head is marked with two short stripes on the crown, 

 followed by two lines posteriorly diverging, and two lon- 

 gitudinal lines behind the eyes. The antennae are rather 

 short, 21 -jointed ; the joints from the fifth to the tip long 

 and slender. The prothorax has a triangular black spot in 

 the middle in front, and two lateral dark lines. The meso- 

 thorax is long, slender, and cylindrical, with a slender black 

 line on each side. The tegmina are small, with the outer 

 apical angle slightly produced, the central carina dark and 

 rather strong. The wings are pale, slightly stained with 

 yellowish brown ; the costal area rather darker, its fore 

 margin dirty white, with the extreme edge for a short 

 distance from the base black ; the transverse veinlets ab- 

 breviated. The abdomen is long and nearly filiform ; the 

 three terminal segments hastate ; the mouth slightly emar- 

 ginate at its apex, exposing the two porrected anal styles ; 

 the seventh and eighth dorsal segments with small black 

 dots ; the three terminal ventral segments short, swollen, 

 not extending to the extremity of the eighth dorsal segment. 

 The legs are very long, slender, and simple; the basal 

 joint of the tarsi, especially in the fore legs, very long.

Obs. The specimen above described has one of the hind 

 legs not fully developed, probably the result of an accident, 

 attended with reproduction of the limb.

I have seen no specimen of this species, and can there- 

 fore add nothing to the description given by Mr. G. R. 

 Gray of the species. 



18. (203.) Phibalosoma Ditomus, Westw. 

 Plate XIII. fig. 1, male. 



Gracillimuni, filiforme, inerme ; antennis 24-articulatis, 

 articulis longis, setosis ; abdomine longo, cyliudrieo, seg- 

 mento 7mo postice paullo latiori : fusco-virescens ; teg-

Hab. In Brasilia. B.M. 



Closely allied to CI. Crypfialeiis, Westw., but consider- 

 ably larger, with the tibiae spined on each side near the 

 base. I have, however, only seen a single specimen of each, 

 not in fine condition, and can scarcely decide on its true 

 difference from that species. The head is rather broad ; 

 eyes large, with a dark mark between them. The antennje 

 are rather more than 2 inches long, 24-jointed ; the joints 

 long and finely hairy. The mesothorax is very long, 

 slender, and cylindrical. The tegmina are small, narrow, 

 and rounded behind, with a strong angulated carina ; the 

 fore margin is pale greenish. The wings are of moderate 

 size and rather narrow, nearly transparent ; the costal area 

 with a very slight greenish-brown tint. The abdomen is 

 long and filiform ; the three terminal segments broadly di- 

 lated, the seventh segment being gradually widened from 

 the base to the extremity ; terminal segment small, emargi- 

 nate in the middle, exposing the two jiorrected obtuse anal
