Moore, differs from the type and from the specimens from Bengal (Calcutta and Murshidabad) in not having the crests of the four posterior femora developed into foliaceous lobes at the apex, and in having the upper crest of the four posterior tibiae more developed and with more regularly arcuate margins, and in having the ridge of the posterior lobe of the pronotum more convex longitudinally. A gigantic female (var. insignis) in the India (olim E.-I. Company's) Museum, South Kensington, marked " N . India," has the lobes at the extremities of the four posterior femora more highly but less regularly developed ; this specimen measures :- Total length 132 millims., length of prothorax 48, of which the neck is 10, abdomen 61-as against 115, 40, 9*5, and 52, the measurements of the same parts in the Calcutta specimen of the same sex. A female in the collection of M r . W . B. Farr (though not labelled as to locality, doubtless from Bengal) agrees exactly with the specimens from Calcutta and Murshidabad. |
