Dr. Stal has siuik this as a synonym of the preceding on the 

 authority of Walker (List Homopt. Sup pi. p. 146), but, as I 

 think, wrongly ; we have three examples of each form and 

 H. viridissima not only differs in size and colour, being much 

 larger and greener than H, camelus, but it has considerably 

 longer tegmina, is far more coarsely punctured, has the front 

 margin of the pronotum bracket-shaped (,-»-^v-^,), the humeral 

 horns prominent, and the posterior process longer.
