seen' to be minute elevations in the eliitin. On the front 

 margin of the clypeus are 4 setae, the middle two shorter 

 than the outer : just behind the front margin is a trans- 

 verse series of G setae, the middle two shorter than the 

 rest. The suture between clypeus and frons is very 

 faintly indicated laterally, but obsolete in the middle. 



Fig. 2.—E. deprtssa, larva. A, dorsal view of head, X 56 : o., 

 ocelli. B, ventral view of head, X 56 : the more chitinised parts 

 indicated by shading: b., base of antenna; c, cardo of maxilla; m., 

 mentiini ( '!). C, whole antenna, X 170 : basal segment somewhat 

 collapsed in mounting. D, antenna, segments 3 and 4, and conical 

 appendage on 3rd, X 350. A and B are drawn from a siJccimen not 

 cleared, but lying in spirit and viewed as an opaque object; C and D 

 from a specimen cleared with caustic potash and mounted in balsam. 



There are several setae, near the middle line, in the frontal 

 region. The epicranial suture is indicated in fig. 2 a by 

 a finely dotted line. The vertex bears on either side a 

 series of about 4 setae, commencing just behind the base 

 of the antenna, and extending obliquely inwards and 

 backwards : and a less regular series of about 3 just behind 

 this. M(jst of these setae, especially on the posterior part
