externally and in front a palpus rising from the middle 

 of a clear ai'ea surrounded by a brown chitinous circle, and 

 apj)arently of two joints, below this and more central is 

 the labrum formed of two round processes each having 

 in front a minute palpus, looking (in front view) like two 

 small concentric circles. Below this the gular reoion is 

 swollen and carries two bristles on either side. 



The 'pwpa of Nanophycs chirieui has much the appearance 

 and outline of the larva, is rather shorter and wider, and 

 is absolutely without any hard, coloured, or chitinous parts. 

 Whilst the dorsum has much the same curve as in the larva, 

 the ventral aspect is nearly straight, the (larval) concavity 

 being tilled by the various projections of the appendages. 

 The head is deflexed, and the rostrum extends downwards 

 ventrally, to about the middle (antero-posteriorly) of the 

 pupa, the anterior end of the pupa being the front margin 

 of the prothorax. From each side of the rostrum extend out- 

 wards, first at its base the antenna, then the first femur, 

 and against it the tibia completely flexed, then similarly 

 the second femur and tibio, the tarsi (1st and 2nd) lie 

 close against the rostrum, the end of the second being 

 slightly beyond it. The femoro-tibial articulation of these 

 legs lies outside the elytra cases, winch however, with the 

 wing cases directed backwards, ventrally, and finally in- 

 wai'ds cover the third legs, except the femoro-tibial articula- 

 tion which just projects dorsaily from beneath them. The 

 wings nearly meet in the middle just beyond the end of 

 the rostrum. 



On the prothorax are a series cf bristles, remarkable in 

 being perched each on the summit of a conical projection, 

 giving an armed appearance to the front of the pupa. 

 These appear to be arranged as a row towards the anterior 

 border and another towards the po terior border of the 

 segment, two on either side in the front and four in the 

 back row, but the marginal two of the latter are not so 

 directly placed in the low as to pro\'ent their position 

 being otherwise described. 



The antennre have a thick basal piece lying against the 

 head or rostrum, from the anterior (position if the head 

 were extended) end of this the flagellar joints extend 

 outwards as above noted, to the number of 10 (or 11) ?, 

 each being larger than the preceding. The joints are 

 somewhat angular, and at about the fourth or iiftli the angles 

 appear as definite projections; on the fifth from the
