THE BUTTERFLIES OF THE NORTH CANADA DISTRICT. 387 



121. Tajuria longinus, Fabric ius. (No. 931.) 



Common along the coast, and, like T. indra^ Moore, the females are 

 almost as often seen as the males, while in the nearly allied genus 

 Camena, although breeding has shown certainly that as many females 

 are produced as males, a female is hardly ever obtained by the net. 

 The larva, which feeds on both the common species of Lorantkus 

 (L. elasticus and L. loallichianus), has the head flattened, and the next 

 segments enlarged : the segments then decrease in size to the anal 

 segment which is broad and rectangular at its extremity. Looked at 

 from above, the caterpillar is broad at the anal segment, narrow 

 nt the next four segments, and very broad at the thoracic segments. 

 In colour it is green, but has triangular marks of mottled white on 

 each side, and a rounded similar mark above on each segment. 



The pupa resembles that of T, indra^ but the abdominal segments 

 are much more angular than in that species. 



122. Ops melastigma, de Niceville. (No. 935.) 



This species we have never seen at large ; but in September, on the 

 Godhalli Hill close to Karwar, we obtained five small larvae feeding 

 on the velvety Lovanthus {L. tomentosus), which we hoped would turn 

 out to be Camena cippus^ Fabricius, as they closely resembled the larva3 

 of C. deva, Moore. Three of these died, but the others, to our 

 surprise, turned into this species. They were very similar to those 

 of C. deva, but the end of the anal segment was prolonged into two 

 short points. The colour also was redder, and they had two lateral 

 red lines. Just before they became pupa3, the central segments 

 contracted, and a triangular green mark, meeting on the back, 

 appeared on each side. 



The pupa was suspended along a leaf or stem, and was very similar in 

 shape to that of Camena cleobis, Godart ; it had, however, two extra 

 points on the second segment, a tubercle on the shoulder, and a conical 

 lateral tubercle on segments 6, 7, and 8, as also a roughened dorsal 

 rising on the same segments. In colour it was a dark apple-green, 

 whitened on the wing-cases ; the last five segments yellow-brown 

 marked dorsally with black and white ; head points pure white ; a 

 white mark along the sides of the thorax suffused with brown. 



We have, since writing the above, taken upwards of twenty larvfe, 

 bave never seen the butterfly at large.
