This resembles E. sulphur eiventris rather closely, but is smaller, 

 rather shorter, with the pronotum much more deeply channelled 

 along the middle and on each side, so that four distinct carina? 

 are formed, the two median ones nearly straight and the two outer 

 strongly oblique. These are always black, whilst the depressed 

 parts of the surface contain blue scales. The scutellum is small 

 and may be with or without blue scales. The elytra are shorter 

 and broader than those of E. sulphur eiventris , with a similar and 

 equally undefined and variable pattern formed by scales of a 

 rather brighter blue colour, which are densest around the scutellum 

 and along the inner and outer margins. The exposed part of the 

 propygidium, the pygidium, and the lower surface of the body are 

 densely covered, as in the Chinese species, with dull sulphur- 

 yellow scales, but the entire median part of the metasternum and 

 abdomen bear instead scales of a beautiful glistening blue, with 

 which the legs are also adorned, but less densely. There is a 

 denuded patch on each side of the metasternum. In the male the 

 front tibia? are more elongate and the teeth shorter and much 

 closer together than in the female. 



ECTINOHOPLIA affinis, sp. 11. (Plate I. fig. 9.) 



Nigra, squamis pallide viridibus supra ornata, pronoti linea 

 integra mediana margineque laterali, ab angulo postico intus 

 retrorsum producto, scutello, elytrorum margin e integro suturali, 

 saepe cum margine tenui externo connexo, viridibus, corporis 

 subtus lateribus pygidioque dense viridi-squamosis, illius parte 

 mediana argenteo-coeruleo-squamosa ; modice elongata, capite 

 rugoso, setoso, vix squamoso, clypeo semicirculari, pronoto longi- 

 tudine sua parum latiori, trisulcato, lateribus antice et postice 

 contractis, angulis anticis acutis ; elytris postice separatim 

 rotundatis, ad sutura? finem setis longis instructis ; pedibus modice 

 gracilibus, posticorum ungue fisso.
