NOTE V. 



FOUR NEW SPECIES OF THE MELOLONTHID GENUS 

 APOGONIA FROM BORNEO 



DESCRIBED BY 



C RITSEMA Cz. 



Apogonia Waterstradti, n. sp. 



Closely allied to and strongly resembling A. abdominalis 

 Rits., from Central Borneo (Notes Leyd. Mus. vol. XVIII, 

 p. 26), but somewhat smaller, the punctuation somewhat 

 stronger, the front margin of the clypeus slightly emar- 

 ginate, the sides of the prothorax more narrowly edged, 

 the pygidium provided with a more or less distinct longi- 

 tudinal keel, the abdomen black *). 



Length 8,5 — 9,5 mm. — Oblongo-ovate; black, the palpi 

 and antennae ferruginous; glabrous and glossy above, beneath 

 the punctures bear small white scalelike setae. 



The clypeus is broad, densely punctured and separated 

 from the face by a distinct suture, the front margin is 

 faintly emarginate, the lateral angles are broadly rounded. 

 The punctures on the face are as large as those on the 

 clypeus but somewhat wider apart. 



The prothorax is transverse, broadest at one third from 

 the base and obliquely narrowed towards the front; the 

 punctures are very distinct, smaller and wider apart on 



1) Of the 20 specimens before me 3 have the undersurface of the body and 

 the femora more or less red coloured. These specimens are certainly not 

 quite mature.
