\OMA ORION {continued). — In the second skin, the 

 larva is at first colourless as it was on hatching, 

 but as it grows, it takes on some colouring, faintly 

 outlining the richness of the adult larva. The 



tubercles are still large, giving a rugged outline to the larva if 

 closely looked at. The 5th and 6th segments are widest. It 

 narrows towards the head and again to the nth segment, the 

 I2th and 13th are again very large, forming two dorsal humps, 

 the head is pale, with two transverse rufous bands. The 

 general colour is creamy yellow, with a red brown dorsal line 

 and another below the trapezoidals. On segments 3 and 4, this 

 lower line runs through the outer trapezoidal and another 

 red line runs between them, the result of the five lines and 

 the tubercles between is to strongly suggest a slashed and 

 puffed sleeve. On 5 and 7 the dorsal line is absent, and is 

 faint on 10. On 6, the two lines meet in a broad band, round 

 the anterior trapezoidal, and in front of the posterior the 

 incisions are also red brown. On 8 and g the dorsal line 

 sends a curved branch forward between the trapezoidals, 

 forming a trident-shaped mark. On the nth segment, the 

 colour is increased by the dorsal line widening behind the 

 anterior trapezoidals and the outer one behind the posterior. 

 12 has the dorsal trident, but no lateral line, 13 and 14 have 

 no lines. 



On the 4th to loth segments (and the others arc similar), 

 the anterior trapezoidals have four secondary hairs, the much 

 larger posterior have five secondary hairs and an indication of 

 an outer row of 10 or 12, the supra-spiracular have also five
