Fam. CRYPTOPHAGIDJE. 



Genus CRYPTOPHAGUS. 



Herbst, Kaf. iv. 172 (1792). 



Cryptophagus impressus, n. sp. 



(7. oblongo-fusiformis, subnitidus, fusco-ferrugineus, pube brevi om- 

 nino depressa parce vestitus ; prothorace transverso-subquadrato, 

 postice paulo angustiore, ad latera oblique subrecto, denticulo 

 medio acuto armato necnon ad angulos anticos in dentem magnum 

 ampliato, in disco convexo, basi in medio late transversim desi- 

 nenti-impresso ; elytris subfusiformibus, convexis ; antennis brevi- 

 usculis. Long. corp. lin. 1. 



Habitat Teneriffam, rarissimus. Specimina duo ceperunt DD. Crotch. 



Two examples of this Gryptoptiagus were captured in Teneriffe by 

 the Messrs. Crotch ; and it is totally distinct from all the species with 

 which I am acquainted. It may be known by its rather fusiform 

 outline, somewhat shining surface, short and perfectly decumbent 

 pubescence, and by the structure of its prothorax which is squarish- 

 transverse, but a little narrowed posteriorly, deeply impressed (like 

 many of the Atomarice) along the central portion of the extreme base, 

 and with the sides nearly straight (though oblique) and furnished 

 with a minute denticle in the centre, whilst the front angles are 

 enlarged into a very prominent (though not particularly elongate) 

 backwardly-pointed tooth. Its antennae appear to be rather short, 

 and its punctation (particularly on the elytra) not very coarse. 



Genus ATOMARIA. 

 (Kirby) Steph., J7/. Brit. Ent. iii. 64 (1830). 



Atomaria laticollis, n. sp. 



A. oblongo-ovalis, pube grossa fulvo-cinerea demissa parce vestita, 

 fusco-picea ; prothorace magno, lato, convexo, per basin ipsissimam 

 constricto, profunde et dense punctato, ad latera valde et a3qualiter 

 rotundato ; elytris convexis, levius ac minus dense punctatis, antice 

 (et interdum postice quoque) gradatim ac plus minus clare dilutio-
