170 Mr. G. C Champion on CoJeopt era from 



eyes and tlie tips of tlic nian(lil)lcs blade, the protliorax 

 \\'n\\ a narrow nicdiau vitta and an oblong spot on each side 

 (the vitta sometimes interrupted and the spot wanting), and 

 the liead in some sjiccimens Mith a spot between the eyes, 

 fnseons, tlie elytra fnscous, with the suture, three narrow 

 lines on the dise (the outer one fainter and abbreviated 

 anteriorly), and the lateral margin more broadly, pale testa- 

 ceous, the ventral surface and metasternum in pait infuscate. 

 liead moderately produced anteriorly, very finely punctate ; 

 eyes large, separated by more than the width of one of tiieni 

 as seen from above; mandibles unclcft at the tip ; antennae 

 long, joint 3 longer than 4, 4-] decreasing in length, 11 

 longer than 10 and feebly constricted at the middle. Pro- 

 thorax longer than broad, moderately constricted behind the 

 middle, transversely depressed anteriorly and also hollowed 

 in the centre before the base ; the surface polished, very 

 finely punctate, with an indication of a smooth median line. 

 Kl}tra much wider than the prothorax, somewhat attenuate 

 posteriorly, closely, very finely punctate, without definite 

 costse. 



^ . Fifth ventral segment excavate down the middle before 

 the apex. 



Length 7-lOi mm. ( c? ? .) 



Loc. Aldabra (1908, Fryer). Madagascar (Mus. Brit.). 



Four specimens, one only of which (a ? ) is from Aldabra, 

 apparently referable to A. lineola, Fairm., the ty])e of which 

 was from Madagascar.

This genus differs from Oxacis in having both mandibles 

 cleft at the tip. No type was given by Pascoe for Sessinia 

 and his name cannot be accepted. The five species referred 

 to Ananca hy Fairmaire and Germain were all from Chile ; 

 the first of these, Nacerdes 23aliens, Sol., which must be taken 

 as the type, proves to have bifid mandibles, and the name 

 Ananca, therefore, must be adopted in place of Copidita, 

 u.>ed by me elsewhere.
