PiiUCOBiUS, nov. gen. (juxta Ocypum locandus). 



Pal]:)i lablales articulo ultimo elongate, cylindrico. 

 Ligula emarginata. 

 Caput collo laivigato. 



The very interesting insect for wliicli this genus is 

 established appears to combine the characters of Ocypiis 

 and Philonthus in a remarkable manner, and would pro- 

 bably, at first sight, be considered an aberrant Philonthus 

 rather than an Ocypus. Its divided and emarginate 

 ligula distinguish it, however, in an unmistakeable man- 

 ner from the former of these genera; and the slender 

 palpi and smooth neck, as well as its general facies, dis- 

 tinguish it from Ocypus. Mandibles elongate, acumi- 

 nate, toothed. Paraglossre large, reaching quite to the 

 apex of basal joint of labial palpi ; 1st joint of labial palpi 

 rather long and slender, scarcely thickened at its extremity ; 

 2nd joint much shorter than 1st; 3rd joint elongate and 

 slender, qiute twice as long as the 2nd. ISIaxillary palpi 

 with the three terminal joints subequal in length; the 

 2nd joint curved, and stouter than the two apical ones; 

 the 4th joint slender and cylindric. Head with a strongly 

 and very abruptly constricted neck. Upper marginal line 

 of thorax extremely deflexed at the front angles. An- 

 terior tarsi strongly dilated in each sex. The middle 

 coxna almost, but not absolutely contiguous. 



The nearest ally of this insect I consider to be Tasgius 

 ater. The Qaedius pectoralis of Boheman, perhaps, be- 

 longs to this genus; and I have from China a sjiecies I 

 should suppose to be that of Boheman, except that the 

 words " caput ovatum" are not at all applicable to it. 



G5. Phucohius simulator, n. sp. Elongatus, parallelus, 

 niger, capite prothoraceque viridescentibus, nitidis ; elytris 

 rufis, dense subtiliterque punctatis, mctasterno rufescente. 

 Long. 5 — 6 lin. 



Mas, segmento 7° ventrali apice ti-iangulariter exciso, 

 excisione parva; segmento 6'" margine posteriore leviter 

 emarginato. 



Antenna3 black, reaching about half-way the length of 

 the thorax, moderately stout, not thickened towards the 

 extremity; 3rd joint considerably longer than 2nd, 4—6 

 differing little from one another, 7 — 10 each a little shorter 

 than its predecessor, the 10th not so long as broad, the 

 11th strongly emarginate at the extremity. Head as
