surface coarsely, rather densely and irregularly punctate, sparsely 

 clothed with shoi-t inconspicuous hairs, and the intervals smooth and 

 shining; anterior margin with a broad median lobe, Avhich is broadly 

 arcuately emarginato in front; prosternal process short, broad, flat 

 and without marginal groo\es, the sides nearly parallel to middle 

 of anterior coxal ca\ ities, v.here they are emarginate and abruptly 

 narrowed toward the apex, Avhich is very broadly rounded. 



Female. — Differs from the male in being larger and more robust, 

 the abdomen beneath more sparsely punctured and less pubescent, 

 and the first abdominal segment feebly convex and smooth at the 

 middle. 



Length, 15-22 mm.; width, 5.5-7.5 nnn. 



This species was described by Chevrolat (1838) from Cuba, and its 

 distribution is probably restricted to that island. Jacquelin Duval 

 1^1857) simply records it from Cuba, and Chevrolat (1867) states 

 that it is found in the eastern and central part of the island, and that 

 specimens are in the collections of Gundlach. Poey, and Chevrolat. 

 Gundlach (1891) records it from the eastern part of the island. 



The following material has been examined: Coll. British Mus. : 

 One male labeled " Cuba (Coll. Chevrolat)" and mnrked type. Coll. 

 Amer. Mus. Nat. Hist. : Male and female collected on the San Carlos 

 Estate, Guantanamo, Cuba, June 18, 1916, bv Chas. T. Ramsden. 

 Coll. Acad. Nat. Sci. Philad. : One female labeled (\iba (Poey Coll. 

 No. ;)39). Coll. U. S. Nat. Mus.: Male and female collected on the 

 San Carlos Estate, Guantanamo, Cuba, June 18, 1916, by Chas. T. 

 Kamsden. (Donated by the Amer. Mus. Nat. Hist.) There is also 

 a single specimen of this species labeled No. 861 in the Gr.ndlach 

 Collection in Havana which has not been examined by the writer. 



This species is easily separated from the other species of this genus 

 found in the West Indies by the two subopaque spots on the 

 pronotum.
