true B. Icibeo of Brod. on pi. xxxv. fig. 207, but afterwards 

 figured the present species, stating that in his opinion the 

 latter was the normal condition of laheo, and the former 

 probably an abnormal form. Since then other specimens of 

 botli laheo and vicaria have been obtained, and they show 

 that the two are distinct species. 



The present species can be distinguished from siihlaheo, 

 Ancey {=Yaf est, var. suhlaheo, Dohrn, MS.), Bull. See. mal. 

 Fr. vii. p. 153, by its light olive colour, the almost entire 

 absence of markings, and the dark purple-brown colour of 

 the columella and parietal wall. The remarkable develop- 

 ment and curious punctured peristome of labeo separates it 

 easily from vicaria and all other known species of the genus. 



XV. — Clservations on some Buprestidge/ro/n the West Indies 

 and other Localities. By CHARLES O. WateeiiouSE. 



A FEW Buprestidse have been submitted to me for determina- 

 tion by the West-India Committee of the British Association. 

 They are as follows : — 



1. Fsilojjtera Guildingii^ Hope, from Mount Gay Estate 

 (leeward side), Mustique Island, Grand Ance (south end), and 

 Eequia Island, Grenada [U. IJ. Smith). These are all of a 

 bluish green, the one from Bequia Island being the darkest. 

 A small specimen (6^ lin.) from Union Island is a bright 

 golden green and very much resembles P. clara. 



2. Chrysohothris tranqiieharica, Gm., from Caliveny Estate 

 (windward side), Grenada [H. H. Smith). 



3. Chrysohothris pulchra, L. & G., from St. George's (lee- 

 ward side), Woburn (south end), and Mustique, Grenada 

 {H. H. Smith). 



4. Mastogenius uniformis^ sp. n. 



This species I have described below. My first impression 

 was that it must be made the type of a new genus ; but an 

 examination of some allied forms has convinced me that this 

 would be premature. 



Mastogenius. 



This genus was founded on a species from Chili. With it 

 has been associated a North-American species which Le Conte
