70 MISC. PUBLICATION 



Dorsal surface : 8-shaped pores tending toward arrangement in short trans- 

 verse rows on median line and in circles near margin, those between definite 

 circles and the median line somewhat scattered but tending toward arrange- 

 ment in circles, 13-16 fi long and 9-10 wide, the median pores as large as any ; 

 minute 8-shaped pores present ; disk pores numerous ; tubular ducts 36 /x long. 



Ventral surface : Antenna nearly flat, sunken in derm, with 2 setae longer and 



3 shorter than diameter of antenna ; with 3 or 4 quinquelocular pores between 

 antenna and margin or with none ; beak with 2 pairs of setae ; spiracular bar 

 fairly broad, sometimes nearly subcircular ; 18-29 quinquelocular pores ex- 

 tending from spiracle to body margin in a row which is single to triple or even 



4 pores wide at margin, occasional pores in some specimens with an elongate, 

 slender, sclerotized projection on edge ; multilocular pores, totaling 118-131 

 and having 10 loculi, in 9 rows of which 5-7 are complete and 2^1 interrupted, 

 anterior row anterior to posterior spiracles, interrupted rows very irregularly 

 arranged ; posterior and penultimate rows each with 10-15 pores, next with 

 16-22, each of next 2 with 20-28, next with 15 or 16, next with 6-11, next with 

 8-15, and anterior row with 2-4 ; a few anterior multilocular pores sometimes 

 with an elongate, slender, sclerotized projection on edge ; 3-5 dark-rimmed 

 8-shaped pores each side of beak, some scattered anterior to mouth parts, a few 

 scattered in lateral area, and a few arranged in 2 transverse rows among multi- 

 locular pores ; submarginal 8-shaped pores in an irregularly single row terminating 

 near the second row anterior to the penultimate row of multilocular pores, about 

 as numerous as corresponding marginal 8-shaped pores ; submarginal setae in a 

 complete row terminating two-thirds length of apical seta from bases of apical 

 setae ; 2 pairs of setae in posterior row of multilocular pores, 1 pair in penultimate 

 row, and 1 pair in first row anterior to penultimate. 



Apex of abdomen : Notch present ; lobes sometimes indicated ; setae, apical 48 

 or possibly 50 fx long, interapical 10.8 /x long, dorsal 5.4-7.2 fx long, inner ventral 

 5.4 fi long, intermediate ventral 5.4 /x long ; anal ring with 6 setae 39-43 fi long and 

 with an inner row of 6 and an outer one of 14 or 15 pores, divided on dorsal and 

 ventral sides ; ventral surface of apex with a slightly sclerotized, elongate area 

 extending anteriorly from base of each interapical seta, surrounding area slightly 

 sclerotized in dentate rows, or sclerotized and rugose. 



Larva. — Nearly elliptical. 



Margin : With 28 8-shaped pores, the posterior 6 pairs slightly smaller than 

 the others and their axes transverse, axes of the others longitudinal ; a pair of 

 minute setae close to each of the posterior 3 pairs of pores ; 3 pairs of setae 

 anteriorly. 



Dorsal surface : 8-shaped pores in a submedian row of 9 and a lateral row 

 of 2 or 3, on oach half of body, with a total of 22 or 23, submedian pores very 

 slightly larger than lateral, and practically same size as marginal pores of 

 same segments ; disk pores in lateral area. 



Ventral surface : Antennal setae, I, 2 ; IV. 1 : V, 1 : VI, 2 long, 2 stout, 

 3 fairly stout, 2 slender : bases of antennae one-fourth length of antenna apart ; 

 beak setae, 2 pairs apical, 1 pair basal ; anterior spiracle with 2 trilocular pores, 

 posterior spiracle with 1 trilocular and 1 quinquelocular pore ; leg setae, coxa 

 4, femur 1 on inner margin near base and 1 each on inner and outer margins near 

 center, tarsus 2 on inner and 1 on outer margin ; tibia one-half length of tarsus ; 

 apparently 8 pairs of submarginal 8-shaped pores, 1 pair of which is between 

 the antennae ; apparently 10 pairs of submarginal minute setae, on abdomen 

 and thorax, 2 pairs of submarginal larger setae at anterior end ; 2 pairs of setae 

 between antennae and mouth parts. 



Apex of abdomen : Notch present ; setae, apical 56 n long, interapical about 

 7.2 fi long, dorsal 2 fi long, inner ventral 3 \x long, intermediate ventral 3 

 fi long; anal ring with 6 setae apparently 20 /x long and with an inner row of 

 6 and an outer row of 12 pores, divided on dorsal and ventral sides : ventral 

 surface of apex slightly sclerotized in dentate rows, or rugose; a small area 

 anterior to each intermediate ventral seta apparently slightly more heavily 

 sclerotized than elsewhere.
