The armature is described from the best-developed male, 

 in which the horns are about as long as the head and, with 

 the connecting ridge, form three-quarters of a circle. The 

 female is similar, but the head bears only two transverse 

 ridges, and the thorax shows only vestiges of the anterior 

 depressions. 0. Antillarum is allied to 0. marginicollis, 

 Harold, which is similar in size and form, while the traces 

 of yellow marking often present in the new species also 

 point to this affinity. It is less shining, however, the 

 striae are not punctured, and the horns of the male, although 

 not longer, are more slender. 



Aphodiid^. 

 Aphodius hiridus, Olivier. 



A single specimen of this almost universally distributed 

 species was found on the Leeward side of Grenada. 



A23hodius cuniculiis, Chevrolat. 



This was found in numbers in St. Vincent, Grenada, and 

 Mustique, and is no doubt distributed throughout the 

 Antilles. It also occurs on the American mainland. 



Atmnius strigicauda, Bates. 



This widely-distributed species was found in numbers 

 in St. Vincent and Grenada, and a specimen was also 

 brought from Becquia Island. It generally occurred 

 beneath rubbish in swampy places.
