to the writer by Dr. Cameron, a few details being added from Dr. Cameron’ 
published notes. 
Larva.— Length, 15-17 mm. 
Width, d.-s., 2.4-2.5 mm. 
Depth, d.-v., 1.5 mm. 
Coloration light chlorophyll green, with two narrow, pale brown lines on dorsum, extendin 
from posterior end, above spiracles, anteriorly, becoming more expanded and diffused o 
fore part of body. | 
Body very depressed, both dorsal and ventral surfaces being flattened, lateral margi 
sharp (Plate LX XXIV, 453). Head completely retractile within prothorax. Skin delicate 
reticulated and roughened. Thorax, viewed from above, semicircular in outline, margind 
with about four tubercles on either side, anterior pair the largest, separated by a V-shape | 
notch. Pronotum with an anterior pair of small tubercles and a larger median tubere | 
behind, directed backward; segments 2 and 3 each with lateral margins two-toothed, t 
anterior tooth the larger and more pointed; a blunt dorsal tubercle on anterior margin an 
a larger one behind. Abdominal segments indistinctly divided into four annuli which a 
poorly delimited; the two basal annuli narrow and corresponding to basal annulus of mo 
crane-fly larvae, the third annulus the largest and bearing a slender lateral tooth; oth 
segments less distinctly divided serrately on lateral margin; dorsum of abdominal segmen 
with a row of blunt median tubercles, there being four on each segment, the first very smq 
to vestigial, the third slender, the last the stoutest; on venter of abdominal segments 1 
7, near posterior margin, a fleshy conical lobe (pseudopodium) on either side of median lin 
these being smaller on anterior segments (1 to 4), and much larger and paler on posteri 
segments (5 to 7). Spiracular disk very large and flattened, obliquely truncated, surrounds 
by six small lobes, the dorso-lateral pair small, widely separated, the ventro-lateral pg 
much larger, the ventral pair very small, slender. Spiracles very small, circular, wide 
separated, the distance between them about equal to six times diameter of one. 
Mouth parts with labrum linguliform, terminating in four teeth, external pair smal 
than internal pair. Mentum with seven teeth on either side of small median one, the fim} 
and the third on either side being the largest. Hypopharynx with two rows of small teet 
Antenna two-segmented; basal segment elongate, pyriform; apical segment thimble-shapdal 
Mandible (Plate LX XXIV, 454) powerful; cutting edge with about five marginal teeth a 
two dorsal teeth; a large basal prostheca. Maxilla large; outer lobe fringed with stiff hai 
a few acute sensory bristles situated on elevated papillae, two on cardo, one on outer lom 
of maxilla; maxillary palpi short, cylindrical, apex obliquely truncated and provided wi 
numerous sensory knobs, on side near tip a circular porous plate (which as it appears 
Phalacrocera is suggested by Bengtsson as probably being an organ of hearing). 
Pupa.— Length, 11.7-14 mm. 
Width, d.-s., 2-2.8 mm. 
Depth, d.-v., 1.4-2 mm. 
Color of live pupa, leaf green; preserved specimens much paler, yellowish; prono 
breathing horns grayish white; margins of abdomen nearly translucent.
