it will attack other species found in the same water. When 

 mature the larvae reach 16 mm. long, are dull reddish purple 

 above, paler beneath and opaque. 



Green found many fully-grown larvae deeply encrusted with 

 Vorticellae. 



The figure of the pupa given in Vol. III. is not quite accurate 

 according to Green. It was figured from a rather shrivelled 

 alcohol specimen. The pupal stage lasts five to six days. Green 

 also notices a broad purple-blue median band on the venter : 

 this does not seem to appear in dried specimens.

Thorax with metallic green scales, an azure spot over the 

 wings. Abdomen purple, banded with pale blue. Legs unhanded 

 in the male, banded with white in the female ; the last two tarsals

9 . Head black, covered with broad flat scales ; along the 

 orbital margin is a narrow band of scales broadening out laterally, 

 which are peacock-blue, in some lights they show purple ; the 

 rest of the upper surface of the head is clothed with metallic 

 golden scales. Immediately around the nape are a few upright 

 forked scales, dark golden in colour ; on the vertex are four 

 golden-brown bristles. Eyes black. Antennae with basal 

 segments black, frosted, naked ; remaining segments black at the 

 nodes, brown at the internodes ; verticillate hairs black. Palpi 

 very short, of three segments, not more than one-sixth the length 

 of the proboscis ; first segment swollen at the base and constricted, 

 the last segment small and nipple-like ; scales broad, spatulate, 

 under a hand- lens dark brown, in stronger light rich blue, except 

 at the tip, where the scales vary from rose-purple to mauve 

 according to the angle at which the light strikes them. 

 Proboscis broad at the base, long and bent, covered with purple 

 and rose-purple broad scales ; at the angle the scales are golden 

 green and some peacock-blue mixed among them. Prothoraeie 

 lobes small, oval, rather prominent ; thickly clad with scales 

 which are purple-blue or rose-purple as the position to light is 

 varied. 



Mesonotum black, densely covered with broadly spindle- 

 shaped metallic green scales ; over the bases of the wings the
