from the margin than in the case of any other vein. Thus vein D 
of the tegmen (anterior ulnar of Shelford’s nomenclature) may be 
forked near the end (see fig. 1), and Shelford states that the 
posterior ulnar (vein E) may be similarly forked ; and in the wing 
vein C may (figs. I, 2 and 3) or may not(fig. 4B) be forked; andin 
the wing vein C may (figs. 1, 2 and 3) or may not (fig. 4) be forked. 
But it is in the secondary veins (b-/) that the variations 
occur which are of special importance in connection with the rela- 
tion between the types of venation found in these three species. 
These veins are usually connected with the primary veins between 
which they lie by a series of more or less ill-defined and very 
irregular cross-veins. The cross-veins are quite irregular in posi- 
tion, in number, and in intensity ; and in some cases the secondary 
veins may appear to arise as definite branches of some primary 
vein, and in others very nearly todo so. Thus in the tegmen vein ) 
often appears as a branch of vein B (see figs. 2 and 4A) or of vein 
C (see fig. 2); and in the specimen shown in fig. 3 vein e of both 
tegmina (but one more than the other) tends to appear as a branch 
of vein E and vein c of the right wing shows a strong tendency to 
appear simply as a branch of C and d of E. 
Having thus established the fact that in Cardax willeyi the 
venation consists of a series of constant primary veins (any of 
which may, however, bifurcate near the margin of the wing), alter- 
nating with secondary veins, which show a tendency to fuse with 
them and so to appear as branches from them, the venation of 
Alluaudella carvernicola and A. himalayensis can easily be shown 
to consist of the same elements somewhat more definitely com- 
bined. But before doing this it will be necessary to describe the 
new species Alluaudella himalayensis. 
Description of ALLUAUDELLA HIMALAYENSIS, Sp. 0. 
(Figs. 5A and 5B.) 
o@ (one specimen only): size, pubescence and antennae as in 
Cardax willeyi; eyes well developed and far apart; ocelli absent ; 
vertex of head not covered by pronotum; pronotum trapezoidal, 
punctured and pubescent behind and at the sides, with longer hairs 
more sparsely scattered over a central area extending as a narrow 
strip to the anterior margin; shape of pronotum, however, not so 
distinctly transverse as in Cardax willeyi. Tegmina and wings 
resembling those of Cardax willeyt in shape, size, texture and 
pubescence ; mediastinal vein very short in tegmina, in the wings 
rudimentary (in one) or absent (in the other); radial vein rather 
faint in the tegmina, coincident with a longitudinal crease; no 
secondary vein developed in front of vein C (= vena spuria, see 
below p. 310) in tegmen or wing ; base of vein C received by vein 
B (=radial) in the tegmen very close to the origin; vein E (= 
posterior ulnar) in the tegmen receives the base of the succeeding 
secondary vein (e), which is strongly developed and appears simply 
as a branch of it. Legs long and slender; apical spines of tibia
