spots on the crown of each lobe, which, as does the rest of the head, emit 
fine black bristly hairs; on the front of the second segment is a narrow 
raised semi-circular plate of greyish flesh-colour, also emitting black 
bristly hairs: the colour of the spines of the dorsal and sub-dorsal rows 
is orange-ochreous, growing whitish at the tips, and of the dorsal rather 
pale at the base; those in the supra-spiracular row are of a paler 
ochreous tint, with more of their tips whitish; the three other rows 
below the spiracles are all whitish ; all the spines are thickly set with 
straight, short, pointed black bristles at an acute angle, and for the 
most part each white spot on the body emits a fine, short black hair: 
the spiracles are black, ringed with whitish; the anterior legs black, 
the ventral legs of a pellucid drab colour, tipped with darker drab hooks. 
The pupa is half-an-inch in length, very plump, with the usual 
angles much rounded off, the abdominal rings bear little rounded emi- 
traces of the larval spines; the tip of the abdomen is bent back 
nences 
at nearly a right angle, and there is a slight depression between the 
abdomen and thorax, which is broad and rounded ; the wing-covers are 
well defined and rather prominent; the warmish white colour and 
texture of the pupa-skin may be compared to that of biscuit china ; 
each abdominal ring is adorned with a transverse brownish-orange bar, 
having on its hinder edge squarish black spots, or sometimes a black 
bar with orange spots, and followed by a row of tiny black dots; the 
back of the thorax is marked with triangular streaks of black, outlned 
with orange, the antenne-cases and wing nervures are marked faintly 
with orange-brown, and the wing-covers and the eye- and leg-pieces 
with strong black blotches and dashes.

DESCRIPTION OF A NEW SPECIES OF COLEOPTERA BELONGING TO THE 
GENUS PRIONOCALUS, WITH NOTES ON THE OTHER SPECIES 
OF THE GENUS. 
BY CHAS. O. WATERHOUSE. 
The characters given by Mr. Adam White for his genus Priono- 
ealus, being founded upon the supposition that two male specimens 
received from Mexico were male and female, are in part erroneous. 
The apical joint of the palpi is described as being “securiform and 
much dilated ;’’ this, however, only applies to the male; in the female 
the apical joint is elongate-triangular with the apex rounded, differing 
but little (except in size) from the preceding joint. The elytra do not 
quite cover the abdomen in the two female specimens before me; the
