230 Mr. Westwood's Observations^ ^c. 



Kirbii. Sp. 2. Sc. fulvo-rufa, abdomine basi nigro-coeruleo, in medio 

 fulvo, apice rufo — femoribus 4 posticis macula media viridi albida, an- 

 tennarum articulis 3 — 10 nigris. 



Long. Corp. (ovipos. incl.) lOAlin. Exp. tegm. 1 iinc. 10 lin. 



Long, antenn. 1|^ unc (fere.) 



Habitat in Brasilia. In Mus. nost.* 



Head fulvous red, face with a diamond-shaped black spot, extending 

 from the nose to the insertion of the antennse, and with a small black 

 spot beneath each eye. Nose and lip paler at the base of each ; jaws 

 and palpi fulvous red ; antennse, with the two basal joints, fulvous ; the 

 eight following black, the remainder fulvous, terminating in brown. 



Prothorax rufous, with an extremely slender, black border, edged with 

 a very delicate yellow line, another very slender yellow central hne ex- 

 tending from the base to the tip, above, and edged half its length with a 

 slight black line on each side. Metathorax and mesothorax fusco-rufous- 



Legs fulvous red, anterior femora with a slender yellow dash at the 

 base above, intermediate femora with a small yellowish triangular spot 

 before the centre, and the posterior with a beautiful triangular greenish 

 white spot near the centre. Tegmina reddish, paler at the tips and at the 

 anal margins, and having four short diagonal pale lines at the anterior 

 margins. Wings pale fulvous red, darker at the exterior margin. 



Abdomen, with the three basal segments blue-black, the third with a 

 rufous transverse line at the base, the three following segments fulvous, 

 each with a very slender black line at the posterior margin ; the remain- 

 ing segments, with the ovipositor, fulvous red. 



The medipectus, postpectus, and ventral •segments of the abdomen 

 yellow. This, by far the most elegant species, I have named after the 

 •celebrated founder of the genus. I was only able to procure a solitary 

 female specimen out of a large collection of Brazilian insects recently 

 arrived in England. 



Edwardsii. Sp. 3. Sc. atra, abdomine coerulescenti, femoribus 4 posticis 

 macula media pallida, tegminibus atris, alis nigro-fuscis. 



* A specimen, apparently of this species, is in the cabinet of Mr. Haworth, but 

 in consequence of not having had an opportunity of examining the individual, 

 I am unable to speak positively upon the subject
