Description. — Head black, pronotum testaceous, sometimes clouded 

 on the disk, elytra testaceous more or less clouded apically, abdomen 

 testaceous generally clouded at base. Head not distinctly punctate 

 but with minute punctulae and transverse strigulae. Pronotum not 

 distinctly punctate but irregularly strigulose and with minute punc- 

 tulae. Elytra without concavity at sides except for a submarginal 

 groove; distinctly punctate but the punctures irregular and more or 

 less composite; without distinct strigulae. Abdomen with punctures 

 obscured by irregular strigulae. Male, eighth sternite with a large 

 triangular emargination about one-half wider than deep; eighth 

 tergite with four blunt teeth separated by rounded notches. Female^ 

 eighth tergite with four slender but triangular processes, the middle 

 a little longer and separated to base. Length, li/^ to 214 mm. 



Type locality. — St. Vincent. 



Types. — In the British Museum. 



Records. — The following are the records known to me: 



Antigua: (H. E. Box, as Blackwelder station 444Q). 



Montserrat: (Hubbard, in U.S.N.M.), 



St. Lucia: (Blackwelder station 226). 



St. Vincent: (Cameron, 1922; British Museum). 



Specimens examined. — I have seen two examples (including the 

 type) in the British Museum, eight in the United States National 

 Museum, six collected by Dr. H. E. Box, and one collected by me in 

 April 1936. 



Reraarks. — This species is the smallest of those having the sides of 

 the elytra unimpressed. It can also be distinguished by the irregular 

 elytral punctation. 



I have seen one specimen from the Museum of Comparative 

 Zoology, collected by Dr. W. M. Mann in Haiti, that keys out to 

 this species. It is 3 mm. long but differs in no other respect I can 

 find except color. I believe it to be a distinct species but will leave 

 it till more specimens are available. 



My specimens were taken in cocoa pods and "from inside of scarlet 

 bracts of a large Heliconia.'^''
