sharp, shortly dentate; anterior angles obtuse, not marked, 

 margin narrowly and very lightly flattened at widest part, 

 strongly reflexed posteriorly; border forming a narrow rim on 

 sides to behind widest part, then merged with edge. Elytra oval 

 (6*2 X 4-1 mm.), convex; apex lightly and widely sinuate on each 

 side; interstices convex, summits punctulate, the puncturation 

 weaker towards base and on third and fifth interstices. Length 

 10, breadth 4*1 mm.

 to me by Mr. W. W. Froggatt). 



Allied to F.australasue, Chaud.,but at once distinguishable from 

 it b}' the 3rd interstice of the elytra less raised into a carina, parti- 

 cularly on apical declivity; head decidedly narrower; ej^es smaller; 

 antennae more slender; maxillary palps more slender (penulti- 

 mate joint especially longer and more slender); prothorax almost 

 similar in shape and sculpture, more convex, more declivous from 

 middle of disc, especially to posterior part of sides and base; 

 sides more strongly rounded on anterior part; anterior angles 

 less marked; elytra similar in shape and pattern, but different 

 by interstices less raised (particularly the 3rd and 5th), more 

 punctulate; the 3rd interstice though raised has its summit 

 rounded, and does not form a strong carina posteriori}^, conse- 

 quently the elytra have not the marked wide sutural channel of 

 E, australasue, though the 1st and 2nd interstices are a little 

 depressed.

Eudema altei^nans, Casteln., I.e. p. 146. 



Elliptical-oval, lightly convex. Black; elytral spots orange, 

 a little distant from base; inflexed margin of elytra with an 

 obscure reddish mark below anterior spot. 



^. Prothorax broader than long (3-9 x 4-5 mm.); margins nar- 

 rowly explanate near anterior part of sides; anterior angles 

 widely rounded, a little advanced; sides lightly rounded at wildest 

 part, subobliquely narrowed to apex (2-5 mm.), strong]}^ and 

 sinuately narrowed to base (3-1 mm.) Elytra oval (9-7 x 6-2mm.);
