A specimen before me from Guatemala differs in the following points from the 

 typical species : — The antennae, instead of being entirely black, have their first joint 

 rufous ; the thorax shows a fine central line of punctures ; and the posterior femora do 

 not reach further than to the second abdominal segment, instead of the fourth, as 

 described by Lacordaire; but the latter character may be sexual. As it agrees 

 perfectly in other respects with the type, the specimen in my hands may be a local 

 variety. 



50. Lema longicornis.

It is not easy to determine with certainty three or four almost identically coloured 

 species described by Lacordaire, of which this is one; and he himself doubts the specific 

 distinction of L. longicornis. The specimens from Guatemala, however, agree per- 

 fectly with Lacordaire's description of L. dorsalis in not having the lateral margin 

 anteriorly marked with piceous, as is the case in L. gracilis. Their length is two lines ; 

 and in one specimen the anterior elytral blue patch is broadly united to the posterior 

 one along the sutural margin. Although this species has a very wide range, it has 

 not been previously recorded from Central America.
