 (1854) description. 



No description is given in the first reference, but a mil des- 

 cription of the b only is given in the second. I think, therefore, 

 the date of the genus ought to be altered to 1854, but I have followed 

 precedent in keeping it 1848. Only three oriental species are 

 known ; all closely allied. 



Larger sp. Thorax and abdomen more 



reddish — wings more brownish, and 



cloud in wings much larger . . julvciornis Sn. v. Voll. 



Long. 12' 13 mm. Thorax brownish yellow 



• — wings with less brown . . . . zonatus O.S. 



R. fulvicornis Sn. v. Voll., 1863. 



{Antidoxion Versl. en Meded. Kon. Acad. v. Weten xv, i, 

 figs. I — 3. ? Java. Type in Leyden Museum. 



Antidoxion of Voll. (1863) was recognised by Gerstaecke in the 

 same year (Entom. Bericht, 1863, p. 410) as a synonym of Rhachi- 

 cerus and Osten Sacken sees no, justification in their separation. 

 I have not seen a description of this species. 



R. zonatus O. S., 1880. 



Ann. Mus. Gen., xvi, 408. 



5 Mt. Singalang (Sumatra), July 1878. Long, (without ovi-
