a spine, two submarginal pores, a spine and a single pore. Submarginal 

 pores with chitinous rims. Dorsal ducts smaller than those of the 

 margin, scattered, their arrangement as indicated in the figure. Micro- 

 ducts very small. Anal opening large, near the center of the pygidium. 

 Ventral side with a few very small ducts. Circumgenital pores in five 

 groups of 5 to 12 pores. 



Second stage very similar to adult but lacking dorsal ducts. 



First stage with the antennae (Fig. 40C) 5-segmented, the ter- 

 minal about as long as the others combined and distinctly annulate ; 

 pygidium (Fig. 40B) with one pair of quite large lobes. 



Notes: This species is very close to L. concolor (Ckll.), but it differs from 

 the latter in the low, rounded and rather widely separated median lobes. In 

 the numerous specimens of both species that I have examined I have found no 

 intergradation.
