48 Mr. David Sharp 07i the 



black, moderately shining. Scutellum large, its punctua- 

 tion similar to that of the elytra. Elytra about as long as 

 the thorax, rather closely and finely but distinctly punc- 

 tured, rendered dull by their distinct pubescence. Hiiid 

 body distinctly narrowed towards the extremity, with 

 strongly metallic reflections; on the apical segments this 

 lustre is fiery and very changeable; it is above rather 

 sparingly punctured, with rigid suberect hairs^ or pubes- 

 cence, on the underside the apical segment is reddish. 

 The legs are pitchy yellow, the anterior coxae pitchy, the 

 middle ones contiguous. Common in heaps of dry rubbish 

 at Nagasaki. 



This species occurs also in Eastern Siberia, Lake 

 Baikal. In China occurs an aUied species {micantiventris, 

 Sharp in lit.) with much more sparingly punctured head 

 and thorax. 



91. Philonthus gastralis, n. sp. (Sec. 8, Er.) Capite 

 thoraceque nigris, leviter metallescentibus, elytris fusco- 

 brunneis, pedibus testaceis ; abdomine apicem versus 

 attenuate, metallico-versicolore. Long. 4 lin. 



Mas, tarsis anticis simplicibus. 



Allied to the P. rutiliventris, but smaller, and dis- 

 tinguished at a glance by the paler elytra and legs. The 

 antenna3 are rather long, the basal joint, and often the 

 apical one or tAvo, paler than the others; all the joints 

 longer than broad, 3rd a little longer than 2nd. Head 

 about as broad as the thorax, broad and short, much punc- 

 tured between the eyes, but with a broad space in the 

 middle smooth, this space bounded in fi.-ont on each side 

 by three or four punctures placed in a row. Thorax 

 narrower than the elytra, quite as long as broad, straight 

 at the sides, and not narroAved towards the front, coarsely 

 punctured, Avith a smooth space along the middle; it (as 

 also the head) has a distinct metallic lustre. The elytra 

 are longer than the thorax, and are of an obscure-broAvnish 

 colour, often much infuscated at the base, and ahvays 

 brighter toAvards the extremity. The hind body is very 

 strongly metallic, and is rather sparingly and coarsely 

 punctured. The legs are yellow, the anterior coxns more 

 or less infuscate, the middle ones scarcely separated. 



In the male the front tarsi are quite simple, and the 7th 

 abdominal segment has only a slight emargination in the 

 middle beneath. 



Found together Avith the P. rutiliventris.
