418 Mr. D. Sliarp's Additions to the 



Ccrcijou ustus, n. sp. Oralis, nitidus, fuscus, limbo 

 dilutiore ; antennis, palpis pedibusqiie testaceis ; crebre 

 punctatus, elytris evidenter punctato-striatis. Long. 2^ 

 mm. 



This species is closely allied to our Cercyon aquaticum 

 and Cercyon laterale, but is smaller than either of these, 

 and also has the palpi shorter than they are in those species; 

 the pale legs and palpi also readily distinguish it fi-om C. 

 aquaticum, and the more rounded hind angles of the thorax, 

 as also the strire of the elytra (which are not deeper behind), 

 from C. laterale. The head is black, and its punctuation 

 is distinct and moderately close. The thorax is pitchy, with 

 .the sides yelloAvish, and distinctly romided near the hind 

 angles ; its punctuation similar to that of the head. The 

 elytra vary in colour, being generally of a testaceous colour, 

 much infuscated ; the amount of the infuscation varjnng 

 considerably; they are distinctly and moderately closely 

 jnmctured, and each has also nine rows of fine punctures ; 

 the sutiu'al one becomes towards the extremity an impressed 

 stria, but the other rows do not. The legs are entirely 

 yeUow. 



Cercyon olihrus, n. sp. Brevis, rotundatus, castaneus, 

 nitidus ; elytris evidenter striatis, striis quatuor internis pos- 

 tice profundioribus, iuterstitiis obsolete punctatis. Long, 

 circiter 2 mm. 



About the size of Megasternum holetophagum, but less 

 convex than that species. Antennas and palpi yellow ; the 

 apical joints of the latter very slender. Head moderately 

 closely and distinctly punctured. Thorax rather finely and 

 only moderately closely punctured. The stria3 on the elytra 

 are at the basal portion formed by rows of fine distinct 

 punctures ; but the internal strife become deep towards 

 the extremity, so that the punctures there disappear ; the 

 external stria^, on the other hand, are formed entirely by 

 rows of punctures, which are obsolete towards the base, 

 but distinct near the extremity ; the punctuation of the 

 interstices is obsolete. The legs are yellow. The under- 

 surface does not differ from the ordinary European species 

 of Cercyon.
