Both are Jamides species recognised by the HW discal white stria forming a spine near the inner margin(dorsum).

1. Jamides bochus. FW postdiscal band ; rounded marginal spots; dark ground colour.

2. J. caeruleus. FW postdiscal band's lower end with dislocated stria ; dark ground colour.
HW 2nd stria in space 7 much nearer to the 3rd stria in the cell.
The white striae appeared thicker than usual for J. caeruleus but is due to the excessive angle of the shot.
Correction : The 2nd is also Jamides bochus. The distortion has made it looks somewhat like J. caeruleus. The striae are not thin.

Post 3.
Potanthus trachala male.
This species is readily ID'ed by the following.
1. FW groups of spots have no overlap (They are joined only by spiny extensions.)
2. Outer margins of spots strongly notched or concave.
3. HW band is partially dislocated at vein 4 into 2 main blocks (not so obvious here).
4. Usually dark blackish smudges prominent.
eg female.

1. FW upper cellspot large (variable) ;Always small or absent in cormasa.
2. FW spots clear : often poorly defined in cormasa.
3. Underside scaling tending to dark chocolate ; deep rusty redbrown in cormasa & FW HW usually well-contrasted.
4. Antenna with prominent pale area ; similar in cormasa but less peominent.
