with its eyes," hut 110 definite truer of the latter are observable. r riie " head " is 

 small, not more than 7 mm. wide, and hetweeii 56 mm. lony 1 at the .sides ; 

 medially it is prolonged into the rostral process, which is ahont 89 mm. long 

 and ending in a sharp point. I am unable to distinguish any dividing line between 

 the "head" ami the prothorax; on the oilier hand, the margin of the latter is 

 continuous with and inseparable from it. The marking which "Woodward ha< 

 regarded as representing eyes is, I believe, the thickened margin. lam of opinion 

 that the whole structure is wholly prothorax, and that the head lies concealed 

 beneath. The main mass of the prothorax is :>() mm. wide, with a flattened margin, 

 best seen on the left side. Within the fiat margins rise two low dome-shaped 

 lobes separated by a wide hollow in front, their margins meeting in an obtuse 

 angle posteriorly. The median edge of each lobe dips sharply into a wide median 

 hollow, and from each of these edges arises a series of veins, which spread out to 

 the lateral margins of the lobes. The areas between the veins are occupied by a 

 fine mesh work of smaller veins. 



A trace of the mesothorax is shown between the bases of the fore-wings as a 

 slight transverse liar, a small rounded tubercle lying in front and a little to the 

 left of the middle line. 



The left fore- and hind-wings are the most nearlv perfect . t he hind-wing being 

 ">' mm. long, with a greatest width of :>0 mm. The fore-wing is a little shorter 

 and narrower. The outer margin appears to have been straight, and the costa 

 and subcosta closely approximated. Traces of both veins are present. The radius 

 is a straight thin vein not far removed from the subcosta along its whole length, 

 and giving off the radial sector beyond the middle of the wing. The radial sector 

 comes off at an acute angle, going out to the wing-apex and keeping elo>rl\ 

 parallel with the radius. The median is somewhat inconspicuous owing to the 

 great length of the main stem, and the narrow areas which bound it between the 

 radius and the prominent cnbitus. It gives off t\vo outer branches before reaching 

 the broken edge of the wing. The median vein of the hind-wing has three 

 outer branches, the first arising nearer the base than the point of origin of the 

 radial sector, whereas in the fore-wing the first branch arises distallv to the origin 

 ol the radial sector. The median of the hind-wing is a more important vein than 

 its fellow in the fore-wing and occupies a greater area owing to its greater inward 

 curvature. The cubitus is a powerful vein with widely spaced divisions, the tir>t 

 branch, both in fore- and hind-wings, coming off from the main stem on the outer 

 >ide, and low down near the base of the wing, and then passing in a bold convex 

 sweep down to the distal portion of the inner margin. On its inner side the 

 cubitus give> off five branches, the fourth forking in the middle of its length. 

 The branches arise ai irregular distances, and the main stem reaches the margin 



far oiil towards the Wing-apex. The cubitus of the hind-wing gives off a large 

 Outer liranch which is almost equal in strength to the main stem. This arises
