Coelidia sexguttat a Walker, 1870 : 314. Holotype 9j, New Guinea (BMNH, London) [examined]. 

 Syn. n. 



Coelidia sexguttata Walker; Metcalf, 1964 : 74. [List.] 

 Coelidia sexguttata var. terminalis Walker; Metcalf, 1964 : 74. 



General colour testaceous; sexual dimorphism apparent. 



Crown ochraceous; pronotum and scutellum testaceous; elytra uniformly testaceous in 

 <J, testaceous in °J with three large ochraceous spots on each elytron, two equidistant 

 on costa and one on clavus. 



Head narrower than pronotum; crown long and broad, produced distally beyond anterior 

 margin of eyes, distal length about one-third entire median length, striate radially, lateral 

 margins slightly concave, disk elevated above eyes; ocelli small, situated anteriorly; eyes 

 moderate size, occupying nearly two-thirds entire dorsal area of head; pronotum with median 

 length less than median length of crown; surface finely knobbed; scutellum large, median 

 length greater than median length of pronotum, elytra elongate, veins prominent, appendix 

 well developed, venation as in description of genus. 



Distribution. Raja Ampat and New Guinea (Walker, 1870). 



Specimens examined. 



Coelidia guttata Walker, holotype $, Raja Ampat Is. (West Irian): Misool 

 (Wallace) (BMNH, London). Coelidia terminalis Walker, lectotype <$, Raja 

 Ampat Is. (West Irian): Misool (Wallace) (BMNH, London). Coelidia sexguttata 

 Walker, holotype $, New Guinea (Wallace) (BMNH, London). 



Coelidia guttata Walker, 1870 is preoccupied by Coelidia guttata Walker, 1851. 



The next available name is Coelidia terminalis Walker, 1870 by priority by 

 pagination. Coelidia sexguttata Walker, 1870 and guttata Walker, 1870 are both 

 synonymous with terminalis. 



Remarks. The above description was based on the type-specimens. No 

 illustrations were made since all abdomens were missing and no other material is 

 available at this time. 



Tharra subapicalis (Walker) comb. n. 



Coelidia subapicalis Walker, 1870 : 312. Holotype $, Raja Ampat Is. (West Irian) (BMNH, 



London) [examined]. 

 Coelidia subapicalis Walker; Metcalf, 1964 : 76. 



No description or illustration of this species was possible because the holotype 

 male is badly damaged. Only the elytra and thorax remain. However, I am 

 placing the species in the genus Tharra with some reservations. The specific 

 identity is virtually impossible and any recourse must be attempted through 

 Walker's original description, which is reproduced below. 



'Mas. Nigra, elliptica, nitens, capite fascia flava, pectore pallide flavo, abdomine piceo, 

 pedibus testaceis, femoribus anticis rufis, alis, anticis linea flava subobliqua. 

 Male. Black, elliptical, shining, very finely punctured. Head with a narrow yellow 

 band in front of the eyes; this band is much dilated beneath. Pectus pale yellow. 

 Abdomen piceous. Legs testaceous; fore femora bright red. Fore wings with a 

 yellow line, which joins the costa at the base, and thence diverges slightly from it to the 

 end of the hind border. Length of the body if lines, of the wings 3^ lines.'
