CATALOGUE OF ORTIIOPTEROUS INSECTS. 



The male of this species is very much elongated, sub- 

 cylindric, and of a dull brown colour varied with luteous 

 markings. The head is as wide as the metathorax, rather 

 flat above, with the eyes very prominent ; between the eyes 

 is a dark patch, within whieli are two small luteous dots 

 resembling ocelli ; the hind part is marked with several 

 dark lines. The antennae are long and slender, luteous at 

 the base, with the joints darker at the tips ; beyond the 

 middle they are slightly marked with broad paler annuli. 

 The prothorax is long and narrow, being about half the 

 length of the mesothorax ; it is obscurely coloured with 

 three dark hues down the middle and sides. The meso- 

 thorax is narrow, slightly dilated behind ; it is brown, with 

 three small luteous spots arranged in a triangle near the 

 fore margin, and behind these is a central larger luteous 

 spot ; the hind part is more obscurely coloured : each side is 

 armed with about ten small spines. The tegmina are ob- 

 long, truncated behind, with the carina elevated into a small 

 cone in the middle ; they are brown, with the outer margin 

 luteous. The wings are uniformly smoky brown, with a 

 large triangular patch close to the tips luteous ; the veins 

 are but slightly coloured ; the costal area is somewhat 

 darker brown, with the fore margin dirty pale buff ; the 

 veins are marked with darker dots ; the median vein simple, 

 united near its ajjex with the following vein. The abdo- 

 men is long, very slender, cylindrical, and dark brown ; the 

 terminal segments fulvous ; these are dilated ; the last fur- 

 cate at its extremity, the furcation armed beneath with small 

 spines ; the anal styles are deflexed, thick, and obtuse at 

 the tips ; the three terminal ventral segments are very 

 short, not extending beyond the middle of the eighth dorsal 

 segment, and considerably swollen ; the middle legs (the 

 only ones left in the unique specimen which I have seen) 

 are very slender and simple, varied with luteous and brown 

 shades.

B.M. 



The only specimen which I had, at first, seen of this spe- 

 cies is a very imperfect one in the National Collection. It 

 is long and slender, sididepresscd, with the middle segments 

 of the abdomen forming the widest part of the body. It is 

 smooth, and destitute of spines or tubercles. The general 

 ■colour is buff with a greenish tinse ; the abdomen brownish. 

 The head is small, and destitute of ocelli ; it, as well as the 

 Iiro- and mesothorax, is marked with a slender, central, dark 

 longitudinal line. The tegmina are small, oblong-ovate, 

 subtruncate at the extremity ; the carina but slightly ele- 

 vated ; front margin brown. The wings moderate-sized, 

 rather narrow, nearly colourless ; the costal area yellowish 

 buff; the median vein furcate at a short distance from the 

 base. Abdomen very long, widest in the middle, gradually 

 attenuated to the tip ; three terminal dorsal segments not 

 different in appearance from the preceding, but shorter ; 

 the terminal one slightly notched at the tip, exposing the 

 two very minute anal styles. The operculum is small and 

 acute, not extending to the middle of the eighth dorsal seg- 

 ment, followed by two elongated flattened appendages ex- 

 tending beneath the ninth dorsal segment. Legs wanting.

P.S. The British Museum has subsequently received a 

 second and more perfect individual of this species, of which 

 the following are the proportions : — 



Long. corp. fere unc. 4 ; cap. lin. 2; proth. lin. 2 ; an- 

 ten. unc. 2\ ; mesoth. lin. 7 ; metath. lin. 7 ; alidom. lin. 24 

 -I- lin. 5=lin. 29 ; styl. anal, porrect. hn. 5 ; ped. ant. lin. 

 27, med. lin. 19, post. lin. 24. 



The legs are very slender, aiul the anal styles long, nar- 

 row and porrected, and acute at the tip, as in PI. VII. 

 fig. 1, and PI. VIII. fig. 2. The specimen appears to be a 

 female, but the oviduct does not extend beyond the middle 

 of the eighth dorsal segment. The expansion of the fore 

 wings is 4i inches.
