Packardia elegans Packard. 

 nigripunctata Goodell. 

 var. fusca Pack. 



Larva. — Head retracted under joint 2 ; joint 2 partly under joint 3 ; 

 dorsal region narrow ; body highest at joint 7, rounding to the extremities. 

 Subdorsal ridges distinct, not raised, segmentally undulate, approaching 

 each other posteriorly and marked with a yellow line which begins on 

 joint 3, not joining over the dorsum. Sides nearly perpendicular, a little 

 sloping and bulging superstigmatally, but not forming a decided lateral 

 ridge; joint 13 produced into a rather long, narrow, pointed tail, marked 

 with reddish purple above. Body closely covered with small transparent 

 granulations ; colour, light yellowish green, dorsal region dark green, with 

 a small dorsal dot on each joint (joints 6-1 1) largely surrounded with pale 

 yellowish green, reaching to the subdorsal lines except on joint 11. Sides 

 nearly uniform yellowish green; above the lateral bulge is a segmental 

 row of depressed darker spots, beginning on joint 4 and becoming in- 

 distinct after joint 9 ; on the lateral bulge a row of yellowish spots on 

 joint 6-9. Spiracles white, small, round, conically elevated A white line 

 borders the venter, which is colourless. Thoracic feet small, abdominal 

 ones wanting as usual in the subfamily. Head green, jaws brown, ocelli 

 black. Length of larva 11 mm., width 5.5 mm., height 3.5 mm. 



The subdorsal and lateral ridges have traces of tubercles, not elevated, 

 but a little smoother than the rest of the body, bearing very minute short 

 setge, just perceptible with a lens in certain lights. These represent the 

 tubercles of the following species : — 



Packardia geminata Packard. 

 Var. albipunctata Pack. 

 ocellata Grote. 

 goodellii Grote. 



Larva. — Body elongate elliptical, sides nearly perpendicular, slightly 

 ridged above the spiracles ; dorsal region flat, highest at joint 7 and 

 sloping each way ; subdorsal ridge moderately prominent, straight ; joint 

 13 prolonged into a pointed tail very faintly marked with reddish toward 

 the end. Along each subdorsal ridge is a series of little conical tubercles 

 (seen with a lens), two per segment, close together and each bearing a 

 very short seta ; a similar row along the superstigmatal ridge, but single 

 and smaller, and the setae even shorter and finer than those on the sub-
