Goiioilo)tlis liypochniria II. -S. I luive wliite; four spots in front cover most of the 



described this larva previously (Ent. News, surface, clypeus pale ; two spots on the nar- 



V, 6i), but the present description is moie row sides; width about .5 mm. Bodyessen- 



full and exact. tially as before, the lateral blunt, brown 



Eifg. Regularly elliptical from upper as- processes present on joints 5 to 9, segments 



l)ect, one end depressed, wedge-shaped from banded irregularly' centrally with red-brown, 



side aspect, the thickerend obscurely truncate, connected by a number of indistinct brown 



consisting only of a slight flattening ; surface lines; interspaces broadly luteous, with 



neatly hexagmially reticular, tlie relicula- many small bright white spots. On joints 



lions distinct and raised, very narrow, but S to 13 the brown dorsal band predominates 



with rounded tubercles at the angles as large and the segmental bands are fainter, being 



as one third the diameter of a cell area. On absent on joints 10 to 13. Thorax all dark 



the side taking the light, the tubercles are above, feet |>ale, abdominal feet dark. Brown 



ilark, pale on the dark side, and on the edge ventral slriiie rather distinct. Later the 



view plainly protruding. The egg is well brown color pales and only the low processes 



rounded, without sharp angles; color shin- (i)ost stigmatal) remain dark,

pink and finally gray-black. Size .8 X .6 X .5 scarcely bilohed. half as thick as higli, whit-

blown, joined by a narrow dorsal line and a dark, except around the very slight elevation 



finer subdorsal one ; feet dark ; venter with behind and above the spiracle (tubercle 



large spots connected like the dorsal ones iii) and in three spots subventrally in an

Later the pale spaces are cut by several shaded. A number of very fine dotted white, 



dusky lines, being resolved into a number of longitudinal lines, viz.: addorsal, obscure; 



white spots. A dorsal pair on the anterior subdorsal, more distinct and on joints 6, 7
