did not appear to last for more than one night. On the afternoon 

 of the 14th the female appeared very sluggish and apparently 

 lifeless. Its colour too had changed to a dark brown. 



The following is a description of the female taken immediately 

 after death : — 



Dark brown. Dorsal segments greatly arched^ shining, faintly, 

 transversely rugose, especially on the lateral areas ; posterior 

 margins of the abdominal segments narrowly ochraceous ; some 

 large irregular patches on the disk of the meso- and metano- 

 tum also pale ochraceous ; lateral margins of all the dorsal seg- 

 ments narrowly shining black ; a distinct, short, central, longitu- 

 dinal carina on anterior area of pronotum vi'hich is posteriorly 

 bifurcate, and beyond this is a narrow central longitudinal sulca- 

 tion continued to about the metanotum ; the lateral areas of each 

 dorsal segment with some shallow pits or depressions. Legs and 

 underside dark castaneous, with the central discal area of the 

 abdomen brownish ochraceous; apical margins of all the abdomi- 

 nal segments clothed with a few short stiff, spinose hairs, which 

 are very easil}^ broken off ; underside of femora and tibae of all 

 the legs armed with short stiff yellowish hairs; apical joint of 

 tarsi very long, as long as or longer than the remaining joints 

 together. Antennae composed of six joints of which the basal 

 joint is very stout, the second joint long, longer than the remain- 

 ing joints together ; these are very short and subequal in length ; 

 some stiff hairs on the antennal joints, the most conspicuous of all 

 being two rather long ones at the apex of the second joint, and 

 a single, long, curved one at the inner side of the apical joint; 

 the palps are also hairy; jaws large, strongly curved, overlapping 

 each other, pointed apically, black and shining on their distal half 

 and reddish-brown on their proximal half. Eyes small, blackish, 

 situated at the base of the antennae. 



The larva from Rambha had eaten nothing for at least ten 

 days. The earth at the bottom of its cage was damped and some 

 water placed in a watch-glass. It was evidently very thirsty for 

 it immediately went to the watch-glass and drank a good deal of 

 water. During the night of the nth October it tried to dig itself 

 under the damp earth, but it did not make much progress. On 

 the evening of the 12th it dug diligently for an hour or so until it 

 made quite a deep pit. The excavated mud was carried in small 

 quantities and placed first a little distance away from the hole 

 and as the hole began to get deeper and the insect was able to get 

 inside, it began to close up the entrance in the same manner as 

 has been explained when referring to the Angul larva. It even- 

 tually hid itself entirely from view and I left it so till the 24th 

 October when I noticed a change had commenced to take place. 

 The larva had begun to cast its final larval skin, but this it did in 

 a very awkward and certainly unusual manner, for insect larvae 

 do not, as a rule, cast their skins piece-meal. First the three 

 dorsal plates of the thorax were cast off, then the first dorsal 

 plate of the abdomen and so on till all the dorsal plates had been
