148 BRYAXIS SIAMENSIS. 



punctatis, striis suturali Integra, discoidali ad basin solum 

 uotata; abdominis segmentis tribus primis subaequalibus , 

 convexis. — Long. l'/j mra., lat. fere ^/.^ mm. 



Hab. Batavia (SijthoflP). — Not abundant. 



Neck closely punctured , gullet with a longitudinal chan- 

 nel , the chin convex , impressed anteriorly , provided on 

 both sides with a callosity before which small setae are 

 present; underlip twice as long as broad, emarginated in 

 a curvilinear manner on both sides. The lateral longitu- 

 dinal groove of the head , in which the maxillary palpi are 

 lodged, is better visible from below than from above. The 

 upperlip is broad ; it has rounded angles and projects over 

 the underlip in roofshape. — The intermediate coxae are 

 large, nearly globose, and as well as the anterior ones 

 contiguous; the posterior coxae are oblong, plain, sub- 

 contiguous. — Wings are present. — The abdominal seg- 

 ments margined. 



Differs from Z. opacics Schauf. by the elytra which are 

 convex, and rounded at the sides, by the abdomen which 

 is somewhat widened towards the end , by the head which 

 is larger and rounded in front, and finally by the size.

Abundant in Java : East Java CMulie) ; Batavia (de Ga- 

 vere and Sijthoff). 



To the description, which was made at the time from 

 a unique specimen, I may now add the following: 



Above the insertion of the antennae are two small tu- 

 bercles behind which an oblique shallow impression which 

 is directed backwards, may be observed. The shining lus- 

 tre behind the tubercles may easily lead to the assumption 

 that an impression is present: this is however an optical 

 illusion in the majority of the cases , as I only succeeded 

 in finding a real small pit in two specimens. — The 11th 

 antennal joint is the largest, short, inversely ovate , slightly 

 acuminate ; the penultimate one nearly globose , the first
