CLCEOTUS. 119 



have seen Cloeotus plicatus and another species feeding on old woody boleti, and a 

 species of the same genus on gall-like excrescences on the midrib of a Paullinia leaf.

On examination of a large series from various localities this species proves to vary in 

 all those points of colour, bloom of surface, and sculpture on which Germar and 

 Erichson relied in separating it into five, for I see nothing in the description of 

 Erichson's A. puncticollis from South Brazil to merit its specific separation from the 

 rest. The character derived from the carinated interstices of the elytra towards the 

 apex seems to be a little more constant than the sculpture of the head and thorax, 

 which is variable among examples from one and the same locality. In nearly 

 all the northern specimens the longer exterior carina is sharp and clear of indenta- 

 tions. This is the chief distinguishing feature in Germar's description of C. glo- 

 bosus. I find it more pronounced in the Jalapa examples captured by Hoge than 

 in specimens of the typical C. globosus from Louisiana. The Cordova specimens in 

 the Salle collection are somewhat different, and show a tendency towards C. sticticus 

 and C. macleayi in the laterally crenated and wavy line of the same carina. Guatemala 

 examples all show a more or less wavy carina, and in those from Chiriqui this feature 

 is generally a little more pronounced ; but I find that it varies even in South-Brazilian 

 examples of C. macleayi. Thus it must be held doubtful if the five species of Germar's 

 Monograph can be maintained even as constant local varieties. Further material from 

 South-American localities is required to decide the question.
