GAUROTES LeConte. 

 This genus was separated by Dr. LeConte for our common 

 Eastern species cyayiipennis, and now contains three species readily 

 recognized by the shining green elytra, which are sparsely and 

 weakly punctured in the typical species, more strongly in abdomi- 

 nalis, and quite closely and deeply in cressoni. The character used 

 to mark the genus in the " Classification," and which we have fol- 

 lowed above, is, strictly speaking, confined to cyanipennis, i. e. the 

 protuberant mesosternum. Mr. Frederick Blanchard first called 

 attention (Bull. Br. Ent. Soc. \ii, p. loS) to the fact that the meso- 

 sternum is not at all protruberant in abdominalis, and only feebly so 

 in cressoni, and the three species might indeed form the types of 

 three genera. We do not find any better character, and the color, 

 fortunately, renders them easy to distinguish and serves to separate 

 them one from another.

A large handsome insect, chestnut-brown in color with a long- 

 attenuated abdomen, which gives it a wasp-like aspect. The form 

 is very slender, and the elytra strongly sinuate as in the ne.xt genus. 

 The last ventral segment in the male is \ery strongly excavated.
