AET. 2 LARVAE AND PUPAE OF THE FAMILY LEPTIDAE GREENE 9 



Larva {fig. 4). — Large, elongate, cylindrical, ivory white; head 

 black, pointed and chitinized when fully extended longer than shown 

 in figure 4; on the antero-dorsal portion are two parallel punctures; 

 near the anterior end of each of these punctures is a pair of short 

 bristles; farther back is another pair of bristles; just posterior to 

 this pair and nearer the median line is a single bristle; on the side, 

 near tlie base, is a single bristle. There are 11 segments in addition 

 to the head ; the first longer than the second ; second segment rather 

 short; segments 3 and 4 of equal length, a little longer than the 

 second; segments 5 to '10 much longer than segment 4, and each 

 succeeding segment slightly longer than the preceding; first three 

 segments w4th deep reddish, mahogany-colored chitin plates on the 

 dorsum; chitin plates on the third segment vary from two large 

 spots, as shown, to a continuous band; anterior spiracle (fig. i) 

 large, chitinized, mahogany red, broadly rounded anteriorly and 

 tapering to a point at the posterior end; in the broad portion is a 

 transverse elliptical blackish area with a round black dot in the 

 middle; in front of this is a broad crescent-shaped yellowish area 

 Avith a middle row of bead-like tubercles, and anterior to this area 

 is a narrow, black, crescent-sliaped band; the segments from 4 to 9 

 have a transverse, antero-dorsal band of red chitinous spines; first 

 segment has three large bristles dorsally on side; segments 2 and 3 

 have two bristles, dorsally, on each side; segments 4 to 10 have two 

 bristles laterally on each side; segments 1 to 10 have a single bristle 

 on the lateral surface near the middle; the last segment has three 

 bristles on each side, and a heavily chitinized plate is present at its 

 apex, anterior edge of plate pointed, and posterior end of plate 

 bifid, each prong curving outward; on the dorsum of this plate are 

 present on each side, one large bristle in the middle; two similar 

 ones laterally, one at the base of the prong and two near its apex; 

 on the ventral surface is a single bristle ; on the dorsum of the plate, 

 near the base of the prongs, on each side is located the posterior 

 spiracle (fig. j) ; this is very dark red; the middle portion is de- 

 pressed and has a large dark spot at the anterior end, and around 

 the middle depressed area is an elevated, flattened ridge divided into 

 62 small rectangular plates; on each side of the middle part of the 

 dorsum of the last segment is a large irregular, chitinous plate, and 

 along the anterior segmental line on each side are two smaller, 

 irregular plates of red chitin which are variable in size. On the 

 ventral surface each segment from 1 to 3 has a pair of widely 

 separated bristles near the transverse middle line of the segment; 

 the venter of segment 1 has red chitin along the anteroir edge 

 extending along the lateral edges until it reaches the posterior end 

 of the segment, and on the segments from 4 to 10 is a transverse, 

 roughened band of small chitinous points present anteriorly; anal
