EXPLANATION OF PLATE. 



Fig. A. Laxva of Rhipiphorus paradoxus, from the interior of a feeding 

 wasp-g-rub, magnified 32 diameters : the small figures 1, 2, 8, &c. 

 mark the head and dorsal plates, the latter being placed at the 

 anterior margins of their several segments. 



Fig. B. Dorsal view of larva of Rhipiphorus paradoxus when about to 

 emerge from the interior of the spun-up wasp-grub, magnified 

 12 diameters. 



Fig. C. Ventral aspect of the same larva. The figures refer to the seg- 

 ments as in figure A, the ventral plates being placed about the 

 middle of each segment. 



Fig. D. Dorsal view of head and dorsal plates of larva of Rhipiphorus 

 (figs. B & C) ; the numbers refer to the corresponding segments 

 of the larva ; magnified 100 diameters. 



Fig. E. Ventral view of head and ventral plates of the same larva, similarly 

 numbered, magnified 100 diameters. The legs of one side are 

 represented, numbered with their corresponding segments. 



Fig. F. Leg, magnified 200 diameters. 



Fig. G. Mandible of right side, magnified 300 diameters. 



Fig. II. Dorsal plate of fourth segment, magnified 210 diameters, show- 

 ing tessellated structure. Figs. D, E, F, G, & II are drawn from 

 specimens mounted in turpentine. 



Figs. I & K. Lateral and ventral views of the tracheal system of the 

 recently emerged larva, magnified 14 diameters, showing the 

 position of the spiracles and indications of the positions of the 

 obsolete spiracles of the fourth and twelfth segments : a shows 

 the appearance of a portion of the intestinal tube of the larva 

 at this stage. 



Fig. L. Full-grown larva of Rhipiphorus paradoxus, lateral view; en- 

 larged 5 diameters.
