line of more or less confluent black spots along each side of the body 
from the base of the pronotum to the penultimate abdominal segment 
which is dusky over the most of its surface, while the terminal segment 
is shining and of a deep brown (or occasionally castaneous) color. A 
black dorsal line extends from near the middle of the metanotum on 
to the seventh abdominal segment and all the abdominal sutures are 
edged with black. A more or less interrupted line of brown dots and 
dashes extends from side to side of each of the first seven abdominal 
segments and in some cases a similar one occupies the same position on 
the meso- and metanotum, though they may be reduced to a lateral dot. 
Form heavy and thick-set much as in the larva of the common D. 
decem-lineata; the prothorax is broader and higher than the meso- 
- thorax, the abdomen broadest near the middle. The figure I give is of 
a specimen in the quiescent state immediately preceding pupation, as 
all were full grown when mailed to me and changed soon after recep- 
tion. Length, measured on the chord of the curve7 mm. 
Labrum transverse, rounded in front and rather deep emarginate, 
the bottom of the margination round. The surface is bristled as shown 
in the figure. 
Ocelli six in number and in two species; the first series, of four, is 
placed just behind the antenna, the other, of two, immediately beneath 
that organ. ; 
Antennæ extremely small, short and thick, joints rapidly reducing 
in thickness. i 
Mandibles strong, heavy, curved, much flattened, five-toothed at the 
extremity. Two views are given to show the appearance under differ- 
ent aspects. 
Maxillæ about equal to or a little shorter than the mandibles, the 
inner lobe short and heavy, beset with many spines around the edge. Pal- 
pi four-jointed, the first joint very large, the second narrower and shorter, 
the third again longer, the fourth about equal to the third in length 
and conical in shape, the tip truncate and beset with very small spines. 
The bristles on the first, second and third joints are few in number but 
very stout. 3 
Mentum with the anterior angles turned inward and partially em- 
bracing the ligula which is slightly emarginate in front and bears short 
two-jointed palpi and several spines as figured. In this figure the men- 
tum is drawn under pressure and the angles are everted from their 
ordinary flexed position. 
Legs stout and rather short with a moderate number of strong spines 
as shown.
