EUPLECTUS ACUMlNATüS. 149 



and 2nd somewhat longer than broad , but little stouter 

 than the succeeding ones. 



The male shows on the middle of the head sometimes 

 a very shallow small groove. The metasternum is widely- 

 and deeply-, the fourth abdominal segment deeply-impres- 

 sed; the first abdominal segment is broad, notched in the 

 middle. 



The female shows only a feeble impression on the me- 

 tasternum ; the abdominal segments have no peculiar cha- 

 racteristics. 



The Javau individuals have the thorax somewhat wider 

 than my type specimen from Siam. In many specimens the 

 base of the thorax, the suture as well as the abdomen are 

 slightly brownish.

 '^Schaufuss, Pselaphiden Siam's. Dresden, 1877. p. 9). 



Very common in Java. 



A. well preserved specimen from Batavia (Sijthoff) shows 

 a richer pubescence on the elytra and on the thorax which 

 makes it appear opaque. In many specimens a small oblong 

 groove may be observed on the vertex ; this groove is much 

 smaller than the three other cephalic grooves. — The first 

 abdominal segment has on the uppersurface on both sides 

 a transverse line (longitudinal when seen from above). 



The milkwhite opalescent wings are longer than the 

 insect. 



6. Bryaxis Fonensis, Schauf. 



(Schaufuss, Pselaphiden Siam's. Dresden, 1877. p. 10). 



A single specimen from Batavia (Sijthoff). 

 When it is full coloured the insect has brighter tarsi , 

 antennae and palpi.
