 zar, on the Windward side ; Grenadines — Mustique I., 

 Becquia I., Union I. 



Eecorded by Mulsant from Guadeloupe I., Colombia, 

 and Guiana. Not known ironi Central America. Found

 Marshall in Antigua. 



Ctesicles. 



Head sunk into the protliorax up to the eyes, the latter trans- 

 verse and completely divided at the sides ; epistoma deeply 

 omarginate in front, leaving the labrum exposed ; mentum flat, 

 small, widened in front, rounded at the sides anteriorly ; apical 

 joint of the maxillary palpi subtriangular ; antennas moderately 

 long, the four outer joints distinctly widened ; prothorax trrns- 

 verse, strongly bisinuate at the base, and closely fitting to the base 

 of the elytra ; scutellum small, strongly transverse ; elytra convex, 

 oval, obliquely truncate and slightly emarginate on either side at 

 the base, the basal margin raised on either side of the scutellum, 

 the humeri more or less obtuse ; mesosteruum feebly excavate in 

 front, the sides very little raised ; metasternura very short ; inter- 

 coxal process of the abdomen broad, rounded in front ; iuflexed 

 portion of the elytra formed entirely of epipleurtE, the latter wide 

 in front and extending to the apex ; tibias rather narrow ; tarsi 

 sparsely clothed with long fine hairs beneath, the anterior pair in 

 the male with joints 1-3 spongy-pubescent beneath and more or 

 less dilated ; body convex, apterous, sparsely pubescent. 



Two species are referred to this genus. It is allied to 

 Blaj)stinns, but differs from it in the form of the elytra, 

 the broader epipleuras, shorter metasternum, apterous 

 body, etc. From Opatrinus it may be known by the 

 non-trilobate mentum, divided eyes, etc. Also allied, 

 but more distantly, to Dlastolinus, Muls. Both species 

 live under stones, drift-wood, etc., on sandy sea-shores. 



Ctesicles insularis, n. sp. (Plate I., fig. 2, S .) 



Oblong oval, convex, opaque above, shining beneath, black, the 

 antennae piceous, with the apical three or four joints ferruginous, 

 the base of the tibiae and the tarsi piceous or pitchy-red ; above
