BULLA LONGICORNIS, Still. 



Eec. Orthopt. i, 1873, p. 139. 



c?. Green, concolorous but with the very narrow border at the 

 lateral sinuation of the pronotum briefly flavescent; antennae long, 

 face with a few scattered granules ; pronotum very highly arcuate and 

 serrate from apex to base, the serration however being closer and 

 sharper in the anterior lobe, the lateral folds being separated by two 

 teeth from each other, the sides as well as the anterior part of the hind 

 lobe bear scattered shining granules, and are not coriaceous except in 

 the lower part, the hind lobe is deeply reticulate with the veins much 

 raised, there is no lateral brown patch on the metanotum ; the ocellate 

 patches on the abdominal segments are not very well defined and are 

 occasionally absent ; anterior and intermediate femora bluntly tuber- 

 culate at base. 



Length 48-53 mm. 



? . Head strongly granular from a short distance from the apex ; 

 pronotum much more highly arcuate than in any other species ( ? ? ), 

 crest of anterior lobe very sharply dentate serrate, but the serration 

 is continued, although not so closely set to the end ; the hind fold 

 of the anterior lobe is deeply impressed, the sides of the hind lobes 

 are reticulate but there are on each side three slanting, not always 

 distinct, slightly raised lines of a lighter hue than the background, 

 reaching the humeral line which is produced to the apex, below this line 

 are five others reaching the margin, these raised lines, which are nearly 

 the same colour as the background, impart a leaf -like appearance ; 

 the median border of the lateral sinus bears a white patch ; abdomen 

 with three lateral superposed series of silvery patches; dorsal and 

 ventral surface also with a median series of irregular silvery patches. 



Length, adult, 51-60 mm.

The description of P. membraciodes, Walk. (Catal. Dermapt. Salt. 

 Brit. Mus. iv, 1870, p. 800) seems to apply to B. longicornis. It is 

 however made from a non-adult form, and the sculpture is apt to vary 

 in the different stages of the instar : " Prothorax highly arched, extend- 

 ing nearly to the tip of the abdomen ; fore part thinly and minutely 

 tuberculate, with four transverse impressed lines and with eight 

 minute crests ; hind part with a contiguous keel, which has tubercles 

 or very minute crests along the whole length. Fore femora tuberculate. 

 Wings none. Length of the body 28 mm." This example was from
