. 



Three specimens, found under bark in the bamboo-thickets on the Pacific slope of 

 the Volcan de Chiriqui, at the highest elevation reached by the present writer. A close 



ally of B. chiriquensis, but differing from it in having the rostrum slightly broader at 



the 



luc utisc, the head more sparsely punctured between the eyes, the prothorax less 

 elongate and feebly constricted near the apex, and the elytra relatively broader, more 

 deeply punctate-striate, and with the interstices convex.

Found in seeds of " Laurus " *.

The type of this insect cannot now be found in the 



Stockholm Museum. It is a small narrow form, and probably not a true Rhyncolus.

MAORANCYLOIDES, gen. nov. 



■ 



llostrum very short and stout, about as long as broad, parallel-sided, unimpressed and almost continuous with 

 the vertex above, the scrobes extending backward to the anterior limit of the eyes and then abruptly 



running downward ; eyes very large, depressed, placed low down at the sides of the head and almost 

 hidden from above ; antennae with a closely articulated 7-jointed funiculus and a small ovate club ; 

 prothorax cylindrical, truncate at the base and apex, unimpressed ; scutellum minute, transverse ; elytra 

 very long and cylindrical, of the same width as the base of the prothorax, conjointly rounded and not

explanate at the apex ; anterior coxae narrowly separated ; metasternum nearly as long as ventral 

 segments 1 and 2 united; tarsi slender, the third joint sub-bilobed, the claws free ; body very elongate, 

 flattened-cvlindrical.

Type, M. perlongus. 





The type of this genus is a very elongate, cylindrical insect resembling Macrancylus, 



■ 



from which it differs in having the rostrum parallel- sided (i. e. not widened basally), 



■ 



the eyes larger and placed lower down at the sides of the head, and the anterior coxae 



Macrancylus and Stenancvlus would be almost as well placed 

 amongst the " Rhyncolini."

Black, the antennae and tarsi piceous, shining, finely alutaceous, subglabrous. 



closely punctate, the head transversely strigose beneath. Prothorax as long as broad, very gradually 

 narrowing from the base, the sides straight, the subapieal constriction faintly indicated ; closely punctate, 

 except along the narrow median line, longitudinally strigose at the sides (fig. 31 b). 

 twice the length of the prothorax, parallel-sided ; punctate-striate, the interstices feebly convex, finely 

 uniseriate- punctate.
