162 SHUCKARD ON THE 



Var. 3. (Celeno.) In this variety the abdomen 

 is much more punctured than in the two pre- 

 ceding ; it is also more quadrate, being \^ » „ „ j nrS 

 broader in proportion to the general size. 

 Its colour is more opaque ; the terminal 

 teeth also have the two central ones closer together, and the 

 lateral ones wider from them, the depth of the central curve or 

 emargination being considerably less than that of the lateral ones, 

 and the apices of the teeth nearly equal. (Length from 3| — 

 4h lines ; from the inspection of thirty -four individuals.) 



Var. 4. (Electra.) In this the puncturing and 

 refulgence of the abdomen resemble Var. 3, 



but the terminal teeth are all at equal dis- V ^ J 



tances.the emarginations they form are of equal 

 depth, and their apices are in a straight line. 

 (Length 3 — 4| lines; from the inspection of nineteen individuals.) c 



Var. 5. (Ma'ia.) In this the puncturing and 

 refulgence is the same as the Var. 3 and 4, 

 but the terminal teeth are considerably bent \rv^rv 



round the lateral emarginations, describing 

 two-thirds of a circle, and the lateral teeth ad- 

 vance beyond the central ones. (Length from 3| — 5| lines ; 

 from the inspection of two individuals.) 



Var. 6. ( Taygela.) In this the sculpture of the 

 abdomen is the same as in the last, but the 

 apices of the teeth describe a slight curve, v^ y 



and the two central ones are closer together Pv-v^>l 



than to the lateral ones. (Length 3| — 4 J 

 lines ; from the inspection of two individuals.) 



I must make a few observations upon the colours of these 

 insects, which have been too often had recourse to for specific 

 subdivision in British entomological cabinets. In every va- 

 riety above described, the colours vary in intensity from bril- 

 liant green and gold to deep blue, and the abdomen from 

 crimson, with a golden refulgence, to purple, and even its 

 darker shades, arising, I conceive, from the quantity of juices 

 within the insect at the time of its death, and also from the 

 mode of killing, or the length of time in dying. As no two 

 specimens agree exactly in colour, I was obliged to resort to 

 what I consider safer characters, but which I think are also 

 doubtful, and characterise nothing more than varieties ; still 

 In this wood-cut there should be but four teeth.
