CANARIAN COLEOPTERA. 179 



being less coarsely bordered, especially in front, and always totally 

 impunetate. Its smooth and shining prothorax (which has merely 

 a row of punctures along its extreme hinder margin) will, apart from 

 all other distinctions, at once separate it from the other Saprini here 

 enumerated. 



Like its more northern ally, the S. lohatus is purely a maritime 

 species, occurring beneath marine and other rejectamenta on the sandy 

 sea-shores. In such situations I have taken it in Lanzarote, Fuerte- 

 ventura, and between Las Palmas and the Isleta of Grand Canarj^ ; 

 in the second of which islands it was- also found by Mr. Gray. I 

 have likewise captured it at Mogadore, on the opposite coast of 

 Morocco. 



Genus 123. XENONYCHUS (nov. gen.). 



Corpus ut in Saprino, sed subtus valde convexum (meso- et meta- 

 stemis abdomineque crassis inflatis) necnou subtus utrinque lon- 

 gissime pilosum : f route marginata, valde depressa ; oculis parvis, 

 demissis, semicircularibus, sub frontis angulo lateral! absconditis : 

 pronoto ubique aequaliter punctulato ; prosterno (ut in Padiylopo)

 nino obsoleta, interdum parum distincta : alls magnis : propygidio 

 longiusculo. Antemup, fere ut in Saprino, sed scapo pilis multo 

 longioribus (sc. longissimis) subtus et supra obsito. Instrumenta 

 cibaria fere ut in Saprino ; sed mandihulis acutioribus necnon ad 

 apicem multo magis et subito incurvis, longe intra apicem deute

 iUarium ac labialium) articulo idtimo paulo longiore et omnino cy- 

 lindrico, in lahialibus multo majore et crassiore quam penultimo ;

 ovali ungidcidis setiformibus rectis (sed in anticis ad apicem ipsum 

 paido inflexis) longissimis {sc. articulo sublongioribus) instructis.
