Long. 16, iat. 3.25 tnm. 



Hab. Perak {Doherty): Suiiiativi: l\in«;-li('ran^--l^isaii^- {Modi- 

 gliani). Two 9 specimens. 



In tliis species, the last alxloniinal se^-iueiit is almost eiilirely 

 uiicoN'ercd by the elytra and is gradually dilaU'd behind; its 

 ventral plate . except near Ihe l)as(\ and its dorsal ])la1e in ihe 

 jiosterior half are ])la(d\, \vilh the hind margin fringeil \\ilh black 

 hairs. The specimen from Sumatra , while agreeing wholly in 

 structural characters differs slightly in markings from Ihe one 

 from Perak. Instead of a black band, it lias three black spo1s a1 

 the base of the prothora.\ ; and the first and fourth segin(>n1s of 

 the abdomen are without black spots, the ^"'' and o''' ha\ing a 

 large black spot on {^ach sidi^ , whereas in the sj)ecimen from 

 Perak, the first four segments of the abdouK^n are all marked 

 with large black spots or bands.

 abdominis utrinque nigro-maculato , segmento primo in cf

Hab. Sumatra : Pangherang-Pisang {Modigliani). 



Very like 0. clava, Pasc. (= armata Gahan) but easily di- 

 stinguishable from that species by the presence of a lai-ge black 

 s[)ot on each side of tlie second adominal segment , Ihe lliii'd 

 segment having souKdimes also a small black sjtot on (vtch side. 

 The mal(^ is witliout the s})iniform process on the first alidominal 

 si^gnu'ut whi(di characterises the male of 0. clara.
