short ami even, the Uitcral ones longer. Later the color becomes broAvn- 
isli with seven red spots on the back, the one on joint 9 paler tiiau the 
otliers. Thei'e are no retractile tubercles at tliis staj^e and the only 
conspicuous Avarts are roAV 2 and the coalesced warts of rows .3-4. 
Second stage. — The structure of the mature larva is now assumed. 
Head shining black; width 1.0 mm. On joints 5-8 a pair of small prale 
orange retractile tubercles, and a single dorsal one on joints 10 and 11. 
Body and warts black with traces of a whitish lateral line. Hair thin, 
some hairs long, others short, black and white mixed. The sides of the 
body become mottled Avith yelloAvish Avith obscure triple dorsal, single

patches on joints 5-11 connected by a broken red dorsal line Avhich 
begins on joint 4. On joints 5-9 these patches have a black central dot. 
Warts of row 2 on joints 2-G and 12 and roAV 3 on joint 2 are blue-black;

distance In front of the large blood-red retractile tubercles on joints 10 
and 11 ; roAv 2 large, circular, subdorsal, normal; roAvs 3 and 4 coalesced, 
I'OAV 3 above the spiracle and 4 behind it, the tAvo forming a guard to the
