Remarks. — This tiny flealike beetle is distinguished from other 

 species of Longitarsus in the West Indies by its wingless elytra 

 lacking humeral prominences and by its black and white antennae. 

 It is closely related to L. oopterus Harold, another wingless species, 

 from Colombia, which has an impunctate prothorax, and L. inter- 

 medius Jacoby from Panama, which is also impunctate but has 

 similarly colored antennae. In L. angusticollis Jacoby the antennae 

 are longer than the body. L. impuncticollis Blatchley from Florida, 

 another wingless species, is dark chocolate brown with fuscous 

 antennae.

 vitta between humerus and apex, in paler specimens only sutural
