Kocif. But the drawings and descriptions of Koch, Rehlese and 

 R, Canestrini are so wrong in all particulars, that I am compelled 

 to publish the mine. 



Larva (fig. 23). Length 220 /t. — Colour carmine. — Shape 

 oval; top forward. — Texture of dorsal shield and coxal shields 

 smooth, of unprotected skin finely wrinkled. — Dorsal side; vos,ÌYwra 

 triangular^ sharp; body divided by a transverse line in a céphalo- 

 thorax and abdomen Céphalothorax short, wider than rostrum; 

 abdomen slightly longer than wide, wider than céphalothorax, 

 almost pentangular, with one of the angles backward. On the base 

 of the rostrum the two stigmata so close together, that they seem 

 to coalesce in one hole. Peritrema tubular, not areolate, shaped 

 like an accolade (-''—). Over céphalothorax and abdomen lies a 

 dorsal shield; this is elongate, truncate anteriorly, convex at the 

 sides, pointed posteriorly, and bears 3 pair of haiis. On the abdomen, 

 on the shoulders, a pair of ei/es directed forward and outward. 

 Moreover 9 pair of hairs, arranged as shown in the figure. Anus 

 terminal, large^ pai'tly doisal. 



Ventral side (fig. 24) hairless; before the anus a pair of distinct folds. 



Mandibles external with thick base and styliform ends. (Fig. 27.) 



Maxillae. The coxae (fig. 24) fused, to form the underside of 

 the head, and the base of the palps. 



Trochanter (fig. 27) short but distinct. Femur nearly as long 

 as the remaining 3 joints together, cylindrical, somewhat swollen; 

 genu slightly longer than wide; tibia slightly longer than wide, 

 almost oval, with distal inside rod-like somewhat crooked (fig. 23) 

 hair or claw. Tarsus fixed on ventral distal end of tibia, sometimes 

 directed downward, as if hanging on the tibia. (Fig. 23). 



i/<?^* (Fig. 23) slender, cylindrical, diminishing in thickness distal- 

 ward. Coxae (fig. 24) 1 and 2 contiguous, coxa 3 close to coxae 2. 

 Coxa 1 with 2, coxa 3 with 1 hair, coxa 2 bare. Tarsi dorsally 

 (fig. 28, 29), with an ellipsoidal olfactory hair on their proximal 

 half. Clares didaclyle, between the claws two extremely thin (fig. 28) 

 nodded hairs ending in a little comb ventralward.
