less flattened, and the striohe are much coarser and stronger. 

 In A. bromeliarum both striolcC and strise are very tine 

 indeed, forming a remarkable and beautiful sculpture ; a 

 ratlier similar type of el) tral sculpture is to be seen in 

 Copelatus incognitus Sharp (Biol. Centr.-Am., Col. i. 2, p. 38), 

 though tliat insect is absolutely diflerent in other respects. 



Aglymbus closely resembles Copelatus, but is distinguished 

 therefrom by the absence of coxal lines. Seven species were 

 enumerated in Dr. Sharp's monograph 'On Dytiscidaj' 

 (p. 596), five from South America and two from Abyssinia. 

 He stated {op. cit. p. 893) that they are '' excessively rare.''' 

 Van den Branden, in his Catalogue of Dytiscidie published 

 in 1885, three years after Dr. Sharp's monogra])h, only gives 

 the same seven species (Ann. Soc. ent. Belgique, xxix. 

 p. 87) J and, although I have searched, I have found no 

 record of any species being added, to the original seven up 

 till now. It is just possible that an Aglymbus might be 

 descril)ed as a Copelatus ; but though I have looked up the 

 descriptions of many species of Copelatus published since 

 Dr. Sharp's monograph, I have found none in the least 

 resembling Aglymbus bromeliarum. Possibly further investi- 

 gation of the fauna of Bromeliaceae will add to our knowledge 

 of the rare genus Aglymbus. — H. Scott.

Long. Corp. ca. 4:\ mm. 



Oblong-oval but not elongate, rather less convex than 

 some members of the genus. Head very broad and short, 

 scarcely narrowing in front of tlie eyes except for the 

 rounding off of the angles, with the front margin straight ; 

 closely and finely punctured ; towards the anterior margin 

 very finely reticulate, this portion appearing dull, while the 

 rest of the head and all the remainder of the upper surface 

 are strongly shining. Thorax closely and finely punctured. 

 Scutellum very finely punctured. Elytra very closely punc- 

 tured (if anything a little more closely than the thorax), the
