ChalcoUenia Iceta^ n. sp. 



-^nea, subtus viridi-aurea ; thoracis disco nigro-eceruleo laxe punc- 

 tulato, linea mediana viridi, lateribus rugosis aureis ; elytrorum 

 sutura apiceqiie cyaueis, costis fere nigris, interstitiis viridibus, 

 regione humerali aurata, macula sub huraero, altera discoidali 

 rotundata ante medium, altera elongata obliqua (medio gutta ele- 

 vata, uitida) ante apicem lajte cupreis, impressis ; femoribus anticis 

 medio lajvibus. 



Long. 9-13 lin. 



This species is so close to G. australasice^ Saund. (Tr. Ent. 

 See. 1872, p. 248, pi. vi. fig. 6), that I formerly considered it a 

 variety of that species. Having now several S])ecimen3, I am 

 sure that it is distinct. The most noticeable character is the 

 oblique coppery impression near the apex of the elytra, which 

 is more conspicuous than in G. austraJasue and cuts off the apex 

 of the second costa, thus preventing its uniting at its apex with 

 the first costa; besides this, the third costa is more abbreviated, 

 a fragment of it, however, appearing before the middle of the 

 impression. The shoulders are more golden, the costce being 

 interrupted there. The thorax has the line of demarcation 

 between the rugose sides and the comparatively smooth disk 

 more clearly defined. The underside of the insect is less 

 golden, less densely punctured ; the abdomen has more smooth 

 space; the inner margin of the metathoracic epipleura is 

 more or less smooth ; but particularly the anterior femora are 

 smooth or very nearly so in their middle, instead of being 

 closely punctured all over. 



Stigmodera Macfarlani, n. sp. 



Thoraco purpureo, cupreo micante, lateribus flavis, seutello viridi ; 

 elytris flavis, ad basin angustissime ceneo marginatis, fasciis duabus 

 latis apiceque cyaneis, corporo subtus viridi llavo ornato. 



Long. 15-17 lin. 



Near S. Spencei, Gory, but with yellow sides to the thorax ; 

 of the same form, but with the thorax a trifle more narrowed 

 in front. Head yellowish green, tinted with coppery, closely 

 and finely punctured. Thorax distinctly and moderately 

 closely and evenly punctured ; purple or coppery red (accord- 

 ing to the position in which it is seen), with the sides broadly 

 yellow; the extreme base at the sides is bordered with 

 coppery. Elytra deep yellow, moderately strongly and evenly 

 punctate-striate ; there is a dark blue spot below the shoulder, 

 and a transverse band across the suture (this band and the 

 spot below the shoulder are united in the second example, and
