216.— Xantholinus ctaneipennis. n. sp. 



Length 6 lines. 

 This species is about the same length as the last, but has a 

 slighter and more elongate look. The head is not so broad, not 

 so truncate behind, is proportionately longer, has the punc- 

 tures between the eyes more numerous, and the oblique lines 

 much shorter. The thorax is as broad as the bead at the apex, 

 which is truncate, bat is somewhat narrowed towards the base 

 which is rounded. The elytra are scarcely wider than the thorax, 

 and are of a chalybeate blue, with a series of small punctures on 

 each side of the suture, and another series in an obsolete de- 

 pression in the middle of each elytron. The abdomen is dark 

 olive, finely punctured and clothed with long soft hair. The legs 

 and palpi are of a piceous red. 



217. — Xantholinds dubius. n. sp. 

 Length 2 J lines. 



Of a pitchy black, nitid. Head longer than the breadth, and 

 rather rounded behind. Thorax rounded in front and behind, and 

 broadest at the base. Elytra sparingly punctured, broader than 

 the thorax, and with a reddish tinge throughout. Abdomen 

 rather dull, with a tinge of red on the two terminal segments. 

 Legs red. 



The last joint of the maxillary palpi in this species is neither 

 so acuminated nor so slight as is usual in this genus. The form 

 of the thorax also, which is very distinctly rounded at the anterior 

 angles, marks it out as being a very aberrant species. 



218. — Philonthus Austealis. n. sp. 

 Length 5 lines. 

 Black, subnitid. Head almost round, with a few large seti- 

 gerous punctures scattered over its surface. Thorax as broad as 

 the head at the apex which is truncate, narrowed a little and 

 rounded behind, longer than the breadth, and marked with a 

 number of large punctures on each side. Scutellum large, tri- 

 angular and closely punctured. Elytra broader than the thorax.
