The localities recorded show this to be an abundant and widely- 

 distributed species. Its occurrence, however, in the Antilles has 

 not been recorded before. 



Three examples. 



EUXESTTJS ? 



Euxestus, WoUaston, Ann. & Mag. Nat. Hist. 1858, vol. ii. p. 411. 



The small insect here described presents, as does the type of 

 Mr. Wollaston's genus {E. parhi from Madeira), the greatest 

 difficulty in its classification. M. Fauvel (Eev. d'Ent. x. p. 162) 

 has regarded Euxestus as a synonym of Plceosoma, Woll. Both 

 insects are now before me, and present great differences in the 

 form of the body, in the length of the antennae, in the proportion 

 of their joints, in the length of the legs and structure of the tarsi. 

 Euxestus is, however, also very similar to an Eastern genus of 

 Motschulsky, Tritomidea. But they are not congeneric ; the 

 structure of the capitulus of the antennae alone will separate them. 

 Our insect from Grenada is so similar to Euxestus jnirJci that I 

 cannot at present point out any differences which would separate 

 it geuerically, but it is probable they will be found. 



Euxestus ? piciceps, sp. n. 



Elongato-ovalis, niger, nitidus, fere glaber ; capite p'otTioraeisque 

 margine antico rufo-inceis ; eh/tHs suhtilissime punctata- striatis ; 

 antennis, 2'>edilms abdomineque rujis. Long. 1*75 millim. 



Hub. Grenada : St. .John's Eiver and Mount Gay Estate, leeward 

 side ; Balthazar and Grand Etang, windward side {H. H. Smith), 



Shining, glabrous, nearly black above ; the head, trophi, legs, 

 and abdomen deep castaneous red. The antennae are ten-jointed, 

 if the capitular apical joint be considered as one, but there is pro- 

 bably a concealed joint in the summit of the capitulus, giving it 

 the appearance of being slightly truncate at the tip, the suture 

 (if one exists) not being made out under the microscope ; the 

 basal joint is large and globular, the second much smaller but 

 stout, the third elongate, gradually widening from the base, the 

 six funicular joints transverse, but becoming bead-shaped near the 

 club. The maxillary palpus has its apical joint awl-shaped and 

 rather long. The legs are stout and short, the femora wide and 

 receiving the tibiae into grooves. Punctuation is visible under the 

 microscope, when the elytra are seen to have series of very fine
