 Bartonian, Ba'i:shot Beds ; Bournemouth {J. S. Gardner'). 

 Brit. Museum, 19004. An abdomen, nearly 12 mm. broad, 

 probably belongs to the same species (B. Mus., 19037). 

 There is also a prothorax, 10 mm. broad, and 5 mm. loug 

 in niid'lle, formed exactly as in CotaJjia Innijiera, but im- 

 punctate, which may well belon-i^ here (H. ^^lus., 19040). 

 The data for the abdomen and prothorax are the same as for 

 the elytron.

Pelidnotites atavus, Ckll. 



This is by far the oldest genuine Scarabaid known, but it 

 seems clearly to belong to the llutelini in the vicinity of 

 Pelidnota and Cotalpa. The reference is strongly supported 

 bv the abdomen and prothorax, which show the presence of 

 such a type in the deposit, or at least indicate a veritable 

 Scarabjeid. As it is impossible to definitely refer the insect 

 to a living genus, I propose the name Pelidnotites for it.
