carin.a (c) separated from the propleural triangle by a continuous 

 caiina. In the insect before me the prosternal sulcus is bordered 

 on its inner side by a strong carina which extends from its hind 

 apex for a considerable distance but disappears at about the 

 middle of the length of the propleural triangle. Moreover the 

 propleural triangle itself is extremely short and does not extend 

 as far forward as the prosternum does, so that the front part of 

 the sulcus is bordered on its inner side (not by the propleural 

 triangle but) by the prosternum. The form of the hind-coxal 

 laminae is also unusual ; they are very wide at their inner end 

 and only feebly (though very decidedly) narrowed towards the 

 lateral margin, so that on the lateral margin they occupy more 

 than a third part of the distance from the front of the meta- 

 sternum to their own hind margin.
