CASE Seira buskii {Lubb.). — 10. Magnified sketch of ditto ; 11. .Magnified sketch 

 ^ll of scale of ditto. 



The antennae of Seira are four-jointed, the body clothed with 

 scales. The terminal segment of the antennae is simple ; it has 

 eyes, and the head is not concealed under the thorax. 



The species S. Buskii is dark violet with metaUic reflections. 

 Lubbock found it only in green-houses and hot-houses, whence he, 

 with apparent justice, infers that it is probably an exotic species 

 introduced. 



No. 12. Templetonia crystallina {Ltibb.). — 12. Magnified sketch of ditto. 



Templetonia is an interesting genus combining a number oi 

 characters belonging to different genera. Its scale is peculiar to 

 itself, and its antennae are five-jointed instead of four-jointed like 

 its allies. The first joint, however, is small, and may be over- 

 looked if not sought for. Its eye consists of one lens in each 

 eye-patch. The species when alive is silvery white, but when it 

 has been a few days in spirits it becomes pale with innumerable 

 reddish brown streaks and spots. It has figured in no less than 

 six different genera, a sufficient indication of the difficulty of 

 placing it in any of the old ones and of the necessity of a new 

 genus for it. Said to be common in Kent. 



No. 13. Beckia ARGENTEA {Lubb.). — 13. Magnified figure of ditto. 



Beckia may be said to be a Seira without eyes. The species 

 argentea is silvery with metallic reflexions.
