XXI. On the Laparostict Lamellicorn Coleoptera, of Grenada 

 and St. Vincent (W. Indies). By Gilbert J. 

 Arrow, F.E.S. 



[Read October 7tli, 1903.] 



In 1900 I published a paper in these Transactions dealing 

 with the Pleurostict Lamellicornia collected by Mr. H. H. 

 Smith in the islands of St. Vincent and Grenada. The 

 present paper contains an enumeration of the remainder 

 of the Lamellicornia of the same collection. The total 

 number of species of the Laparostict families is 22, making 

 in all 40 species of Lamellicorns now known from the 

 islands. Of the present 22 species, 9 are known as in- 

 habitants of the mainland of America, 2 more have been 

 described from other islands of the Antilles, and 10 are 

 here described as new. One of the latter, Atxnius 

 tenehrosics, is also a widely-distributed form and, with the 

 exception of 3 rejaresented by single specimens and 3 by 

 two specimens, only 3 of the whole number did not occur in 

 both islands ; and two of these three occur elsewhere. The 

 families dealt with in my previous paper therefore differ 

 curiously from those now under consideration in the 

 localization of their species. 



The fauna of St. Vincent has assumed a very special 

 interest since the volcanic catastrophe from which the 

 island has so recently suffered, and which can hardly have 

 failed to produce a permanent effect upon its fauna and 

 flora. It is fortunate that so excellent a collection was 

 brought from the island before the event, so that future 

 comparisons will be possible which should throw valuable 

 light upon biological problems. 



I have also characterized in this paper a few Central 

 American allied forms, as to which confusion has previously 

 existed.

 Grenada, and Mustique in the Grenadines. It has only
