and slenderer. The maxillary lobe is short and thick, the end rounded, 
fringed with a dense brush of short erect hairs. The ligula is small 
and short, the labial palpi small, of two joints, the first short and thick, 
the second more slender, nearly three times as long as thick. The oular 
sutures, mentum, and base of maxille, are usually outlined in darker 
color. The antenne are four- -jointed, the first short and very broad at 
base, the next two about equal in length, the second a little longer than 
thick, the third more slender, the fourth subulate, shorter, borne at the 
upper side of the apex of the third, which also bears below this a small 
accessory article about half the leneth of the fourth. Eyes wanting. 
First thoracic segment reddish brown, with the posterior border 
minutely rugose-granulate, extending forwards in a point upon the 
median line; anterior margin narrowly rugose, remaining surface smooth 
and shining; one half longer than the next segment on mesal line; this 
latter and the following segments, except the last, similar in size and 
vestiture. The surface of the abdominal seoments is varied by naked 
impressed lines, finely transversely ridged, as follows: a dorsal row of 
V-shaped impressions, one at the anterior edge of each segment; a sub- 
i dorsal row of oblique impressions; and a lateral impressed line, inter- 
rupted at the sutures. Beneath is a similar pattern of sculpture. The 
spiracles are raised upon short subcylindrical shining tubercles. The 
“ first pair are at the extreme anterior lateral angle of the second thoracic 
| segment. The remaining nine pairs are upon the abdominal segments, 
a little higher upon the sides. The first ones are nearer the anterior 
margin of the segment, but posteriorly they approach the hind margin, 
and those on the ‘penultimate segment are longer and project. backwards 
beyond the posterior margin of the segment. "On the last segment they 
appear as two slender black-tipped tubercles on the upper surface. 
| Beneath the tubercles, and nearer the hind margin of each segment, is 
a pubescent tubercle. The last segment is about two thirds as wide as 
the preceding one, semicircular, shining, colored like the head, bearing ~ 
posteriorly a pair of stout hooks projected backwards and curved up- 
| wards, with a strong inner seta-bearing tooth near tip, not as long as the 
tip itself, which also bears sete. Legs rather short, four-jointed, with 
a single claw. Anal proleg short, cylindrical. 
Pupa. (Plate IV., Fig. 4.)—Length 5 mm., greatest width 2.2 mm. 
Elongate-oval, tapering posteriorly, brownish testaceous ; head, wing- 
| pads, and legs usually paler. Surface subopaque, minutely and densely 
-_-punetate, and very minutely pubescent, with smooth spaces at bases of 
_ wing-pads and on metathorax. 
: Vertex of head with a pair of large spines on each side. Just over 
each eye is a pair of minute spines, and in front of these another pair 
on each side. The labrum is rather strongly notched. 
Prothorax with four spines on the anterior margin, the inner 
largest of all; four spines on each side, one at each angle, and the re- 
maining two nearer the angles than to each other. Within the line of 
‘marginal spines are three smaller ones on each side of the disk. The 
—_ seutellum is three fourths as long as the metathorax, which is as long as 
the first three abdominal segments, and is longitudinally suleate at 
middle. The elytra reach to the hind knees, and the hind tarsi reach
