attenuata, postice ampliata) in thorace, duabus maculis 

 magnis subanguliformibus duabus que miuutis suturalibus in 

 elytris, pectore et abdomine lateribus virenti-albidis. 

 Long. 15 tin., lat. 5 lin. 



The figure by M. Migneaux in PI. III. renders any further 

 description unnecessary. 



It is a rare species, much prized for its beauty. 



Sternotomis. 



1. Sternotomis imperialis. 



Lamia itnpertalis, Fab., Westw. Arc. Ent. ii. 149, pi, 86. f. 3. 

 Ceranihyx luteo-obscurus, Voet, Col. ed. Pz. iii. 20, 19, pi. 7. fig. . 



ornatus, Oliv. Ent., Ceramb. pi. 4. fig. 24 c. 



Lamia bifasciana, Fab. Ent. Syst. i. 281. 



I have taken this synonymy from Westwood's ' Arcana.' 

 It differs entirely from that given by M. Chevi-olat ; but, on 

 looking into the citations, I am satisiied that the above corre- 

 sponds best with the descriptions and plates. M. Chevrolat 

 doubtless rests his opinion upon a different estimate of the 

 value of the variations of the species, or upon a traditionary 

 knowledge of the types. 



Not very rare. When it arrives in spirits, the green parts 

 of this insect are of a lovely iridescent rose-red, slightly 

 changing to green. 



2. Sternotomis chrysopras. 



Cerambyx chrysopras, Voet, Col. ed. Panz. iii. 21, 22, pi. 9. fig. 22 j 



Schonh. Syn. Ins. vol. iii. p. 373. 

 Sternotomis chrysopras, Westw. Arc. Ent. ii. 155, pi. 86. f. 1. 



Rare. 



3. Sternotomis Targavei (Reiche), Westwood, Arc. Ent. 

 1844, p. 154, pi. 86. fig. 2. 



In Prof. Westwood's figure, the apical portion of the elytra 

 is figured green ; but in my specimen it is yellow almost to 

 the point. 



This beautiful species is exceedingly rare. 



QuiMALANCA, J. Thoms., Lac. 

 Quimalanca regalis. 

 Sternotomis regalis, Fab. Sp. Ins. i. 217. 

 Common.
