428 Mr. R. M'Laclilan oji Notiothmima Reedi, 



joints ; basal joint rather long and stout, dilated at the 

 apex; 2nd joint partaking of the same nature, but shorter 

 and thinner; the 3 or 4 succeeding joints short, and nearly 

 quadrate, afterwards the joints to the 14th or 15th are 

 more or less conical, then becoming longer and nearly 

 oval, but those at the tip again shorter. Front (from the 

 fragment that remains) apparently shortly rostrate. Maxil- 

 lary palpi with a very short basal joint, a long curved 

 2nd joint dilated gradually to the tip, a shorter (also 

 dilated) but stouter .Srd joint, the 4th and 5th short, the 

 latter obtuse. Body rather slender, subcylindrical. Meso- 

 notum furnished on either side with strong erect spines. 

 Metanotum transversely quadrate. Abdomen (?) much 

 shorter than the wings, having at the sides the terminal 

 three segments gradually diminishing, so that the apex is 

 nearly conical ; the apical segment furnished with a pair 

 of slender 2-jointed hairy cylindrical appendages, slightly 

 curved, and directed outward almost at right angles. 



Wings perfectly horizontal in repose, one overlapping 

 the other (as in Termes), equal (the posterior slightly the 

 shorter), broad, nearly oblong with broad rounded 

 apices, almost coriaceous in texture (the posterior rather 

 less so) ; the extreme base of the inner margin Avith a 

 well-developed nearly semi-circular lobe ; reticulation very 

 dense, the nervures and nervules elevated and very strong. 

 In the anterior wings the costal area is very broad, 

 narroAved at the extreme base, where there is a stout, 

 simple transverse nervule ; this area is occupied by four to 

 six irregular rows of cellules, mostly irregularly hexagonal 

 in form, smaller and more numerous towards the costa, 

 larger and elongate above the subcosta which is indis- 

 tinctly separable from the general reticulation, and which 

 ends in a rather large space, before the apex, free from 

 nervules, but very coarsely tuberculate, forming the 

 pterostigma ; radius also indistinct, running into the apex, 

 connected with the subcosta by transverse nervules; sector 

 arising at an angle in the radius towards the base, its 

 upper branch running parallel to the radius; the upper 

 cubitus originating at the same point as the sector, the 

 lower from the base of the wing. The sector and cubiti 

 have an infinitude of branches, all connected by numerous 

 transverse nervules, so that nearly the whole Aving is 

 occupied by elongate irregularly hexagonal cellules, be- 

 coming shorter and more numerous at the apex ; at a 

 point on the upper cubitus, about one-third from the
