not by a retractile stinging apparatus, described by Duncan 

 as belonging to his Doratifera vuhierans. Our stinging Lima- 

 codes wounds with its external armature in the same way as the 

 larva of our Saturnia lo. Of the tubercles, besides the four 

 long, conical ones, there are four of a spherical form before, two 

 behind, and one on the side of each segment of the body. 

 Body before, behind and beneath, and an oval spot on the 

 back, reddish-brown ; sides and rest of the back green, bor- 

 dered with a white line. 



The next figure represents a very different larva ; in form 

 somewhat like an Oniscus, being oval and flattened, with lat- 

 eral tooth-like appendages fringed with hairs. General color 

 green, with lateral rows of minute, ocellated spots, each pupil- 

 lated with a black dot ; a dorsal row of dark spots, with two 

 of a rich scarlet color (in the figure black). Sonrel has made 

 me a magnified sketch of this curious larva [Plate ii, fig. 7 : 

 PI. Ill, fig. 6], showing the beautiful manner in which its 

 body is delicately variegated. This insect does not sting. 



The third form [PL iii, fig. 8] is that of my Liinacodes 

 scaplia. It is a " chunky " larva, almost lozenge-shaped, with 

 the back concave and the sides turned up, somewhat like an 

 old-fashioned cocked hat. Color green, edged and variegated 

 with brown. 



Limacodes cippus [PI. ii, fig. 2], approaches somewhat to my 

 first figure, but is still different, having a greater number of 

 elongated tubercles, not beset Avith stinging prickles. 



Limacodes pitfiecium is occasionally injurious to fruit trees. 

 It casts off its singular,lateral, velvety appendages before mak- 

 ing its pea-shaped cocoon, and then has the form of a kernel 

 of coffee. 



I have not succeeded in obtaining the winged insect from the 

 first figured Limacodes, my specimens having died in conse- 

 quence of the attacks of the little Ichneumons wherewith they 

 were infested. The onisciform Limacodes has not left the pu- 

 parium.
