THE CRANE-F urs oF New York — Part II 845 
ated with the larvae of the syrphid fly, Temnostoma bombylans (Fabr.) 
and the supposed larva of Protoplasa (p. 770). 
Larva.— Length, 18 mm. 
Diameter, 1.6 mm. 
Coloration pale whitish; anterior segments of body brighter-colored, more reddish. 
Form stout and plump, not narrowed at ends of body. Pronotum longer than other 
thoracic segments. Integument covered with a short appressed pubescence. Abdominal 
segments 2 to 7 with conspicuous white creeping-welts on ventral surface of basal ring; these 
welts not interrupted medially, and entirely naked. Spiracular disk (Plate XXXVI, 163) 
large, unmarked, surrounded by five short lobes, the ventral pair very widely separated; 
dorsal lobe broad and obtuse; entire disk fringed with very short, delicate hairs which are 
interrupted only between paired lobes; inner face of lobes suffused with pale brown at tips. 
Spiracles large, circular, reddish with a very broad yellow margin, separated by a distance 
nearly equal to two times the diameter of one spiracle. Anal gills four, retractile. 
Head capsule (Plate XXXVI, 158) broad and massive, the constituent plates firmly united 
except on ventral parts. Labrum broadly transverse; a median epipharyngeal part whose 
surface is finely pitted, bearing on ventral! side near margin two stout setae; lateral angles of 
labrum directed proximad and densely tufted with hairs; extreme lateral margins of labrum 
with a curved hyaline seta; juncture of labrum and clypeus with two large setiferous punctures 
on either sid3; a few setiferous punctures on head capsule. Mentum (Plate XXXVI, 159) 
heavily chitinized, the outer face terminating in a single median tooth, behind which is a 
tridentate plate with three flattened teeth, the lateral ones very broad. Prementum (Plate 
XXXVI, 160) lying just behind mentum, a moderately broad transverse plate whoce 
anterior margin is deeply and almost squarely notched, the lateral lobes thus formed being 
rounded or feebly indented at their tips. Hypopharynx (Plate XXXVI, 161) lying above 
and connected with prementum, consisting of a large flattened lobe, whose outer margin 
is evenly rounded, the surface densely set with longitudinal rows of small, sub=cute papillae. 
Antenna short, two-segmented; basal segment cylindrical, with auditury plate almost basal 
in position; apical segment small, subglobular or hemispherical. Mandible mcderate in 
size, broad at base with a blunt apical tooth and a few blunt lateral teeth, two on dorsal 
cutting edge and two on ventral cutting edge, the more basal of these latter tending to be 
evanescent; two stiff setae at heel of mandible; a triangular lobe on dorsal face which 
projects onto lateral parts of labrum. Maxilla (Plate XXXVI, 162) primitive in structure; 
cardo elongate, transverse, with four setiferous punctures bearing powerful setae; outer lobe 
glabrous, with palpus at its tip; palpus slightly elongate, the auditory plate just before 
midlength; a seta on outer lobe below palpus; inner lobe of maxilla with a dense terminal 
brush of stiff yellow hairs and a few sensory papillae. 
Pupa.— Length, 12-12.5 mm. 
Width, d.-s., 2-2.1 mm. 
Depth, d.-v., 2-2.1 mm. 
Head, thorax, and appendages brown, becoming darker with age; pronotal breathing 
horns light red; abdomen whitish, the terminal rows of spicules on the segments chitinized.
