Hab. Panama, Bugaba (Champion). — South Ameeica, Cayenne 2 , Brazil 234 . 



A single female specimen from Bugaba is referred to this species, originally 

 described from an introduced example of the same sex found at Boston l . There is 

 a short series of the same species, including both sexes, from Brazil, in the Fry 

 collection at the British Museum, and the above description is supplemented from

2. Dynamis peropacus, sp. n. (Tab. IV. figg. l, c? ; 2, $ .) 



Black, opaque and strongly pruinose above, shining beneath. Eostrum a little shorter than the prothorax, 

 feebly curved, strongly compressed and of almost equal thickness (as seen in profile) to the tip, in both 

 sexes dilated at the apex (as seen from above), and very finely, sparsely punctate. Prothorax gradually 

 narrowing from the base, the median lobe broadly, arcuately produced, the surface with minute scattered 

 punctures. Scutellum small, oblong-triangular, and with a smooth lanciform median ridge. Elytra 

 each with five narrow, moderately deep sulci, the fourth and fifth not confluent at the apex, the outer 

 striae almost obsolete and represented by four sinuous lines of very fine punctures, the dorsal interstices 

 flat at the base and becoming feebly convex towards the apex. First ventral segment hollowed down 

 the middle anteriorly in both sexes. Femora and tibiae densely fringed with long matted blackish-brown 

 hairs in the $ , the hairs shorter in the $ , 



Length 32-36, breadth 13|-15 millim. ( c? ? .)

Hah. Nicaragua, Chontales (Richardson). 



Two males and one female. Extremely like Bhynchophorus palmarum, but with 



a very much stouter, compressed, apically dilated rostrum, which is not cristate in the 

 male, a longer median lobe to the prothorax, and a much smaller scutellum. The 

 velvety-black opaque upper surface, the broader scutellum, and the narrower elytral 

 sulci (the fourth and fifth of which are not coalescent at the apex) separated by flatter 

 interstices, sufficiently distinguish D. peropacus from D. germari. It seems curious 

 that this species was not obtained by either Belt or Janson at Chontales.
