These two species are the first representatives of this 

 large group so far recorded from any of the West India 

 Islands. 



A noticeable point is the apparent rarity of the males of 

 Plcdris. Among ten specimens from St. Vincent there is 

 a single male of one of the species only and a similar 

 disprojjortion seems to occur in other species. The various 

 characteristics peculiar to this sex are also remarkable. 

 An upper surface distinctly less glossy than that of the 

 female seems to be of general occurrence, and besides this 

 and its more elongate form the male of P. fungicola is 

 distinguished by the elongation of its maxillary palpi and 

 the dense clothing of long hairs upon its hind tarsi. Other 

 species show an extraordinary development of the posterior 

 tibial spurs. 



RUTELID^. 



Anomala inconstans, Burrn. 



Six specimens of this insect, which seems very liable to 

 local variation, were found at St. Vincent. Although 

 showing all degrees of coloration they all belong to a 

 variety very near that mentioned by Bates from Cliiriqui 

 (Panama), having prominent costte and narrow interstices 

 to the elytra. They are also rather smaller than con- 

 tinental specimens. Examples of the same variety have 

 been brought from the neighbouring island of Santa Lucia.

0. tristis is a deeply striated insect intermediate in 

 appearance between G. chalconota and C. victaUiai, being 

 of about the size and shape of the former but rather more 

 depressed and without its thick hairy clothing. It is at 

 once recognizable, however, by its sombre colour. It is a
