74 THE entomologist's record. 



consisting of the largest spots frequently joined together into 

 portions of a circle. The number of spots in each circle 

 would be perhaps 6, 12 and 15 respectively where each row is 

 most regularly developed. The micropylar spot is small, and 

 surrounding it, the ribs join together in a wider area than 

 usual of confused and irregular ridges, not settling down into 

 regular ribs till half way to the margin. 



The newly-hatched larva (PI. V., fig. 10) is fully 2 mm. long, 

 the head is black early, but the rest of the larva pale, the dark 

 segments being marked by the dorsum being reddish-rufous ; 

 as it begins to feed, however, it becomes much darker. There 

 is a black plate on segment 2. Segments 5, 7, 8.9, 12 and 13 

 (and partially 4) have the dark dorsal areas (dark segments). 

 The tubercles on these segments are white when the larva is 

 just hatched. When the colour matures after some hours, the 

 general tone is fuscous, 3 is paler, there is a large white area 

 on 6, and 10 and 11 are white, the tubercles are black even on 

 these pale segments, larger on the dark ones, angularly 

 flattened against each other, but on 11 much smaller, circular, 

 and separated from each other. On 12 they are cruciform and 

 trapezoidal reversed (as usual) on 13. The tubercles each 

 carry one long hair, about twice the diameter of the larva in 

 length, the anterior trapezoidals each have two ; four on those 

 of 3 and 4, and three on those of 12. The skin is finely dotted 

 all over except on whitest portions ; on 3 and 4 the trapezoidals 

 are fused. The divisions of the segments into two sub- 

 segments carrying each the anterior and posterior trapezoidals 

 are very evident in this species. The head carries long hairs. 

 The larva sits curled into a note of interrogation (?) form ; it 

 sits beneath the leaf and eats the lower parenchyma between 

 the veins. 



In the 2nd skin, it sits coiled in a circle with the head 

 against the 12th segment, and this is its attitude at rest till it 

 is full-grown. In this skin, it still leaves the veins and upper 

 cuticle. The colour is a very deep brown (black at first 

 glance) with some white markings. It has white marks on 

 2, 3 and 4, tending to form a dorsal line and circles round the 

 tubercles, but most marked laterally on 3. Segment 6 has 

 white marbling concentrated into rings round trapezoidals 

 and supra-spiracular. On 10 and 11, these rings are so large 

 that the segments might be called white, with a dorsal and 

 sub-dorsal dark line, especially as the tubercles are pale, and 

 on II nearly white. The segments are swollen with deep
