examined. Three of these are alike in every respect and are taken 

 to be the type species. One of two specimens in the collection 

 of the American Museum of Natural History is different and is iden- 

 tified as B. sahlbergi Popp. That species is distinguished as follows: 

 " Sehr nahe verwandt mit B. heimingianus Sahib, unterscheidet sich 

 aber durch schmaleren Kopf, der sparlicher punktiert ist, besonders 

 aber durch den bedeutend schmaleren und etwas langeren Halsschild, 

 der nach hinten etwas starker verengt ist. Die Fliigeldecken sind 

 etwas langer, viel weitlaufiger und etwas feiner punktiert und starker 

 glanzend." The two American specimens at hand most closely re- 

 semble this specimen, which carries the pin label " Fennia. Reitter." 

 They differ in having smaller heads, shorter and more strongly dilated 

 elytra with less prominent shoulders and the elytral punctures are 

 coarser and less closely placed. They differ in these respects from 

 B. henningiamis and also in the thorax more strongly narrowed be- 

 hind. In one of the specimens the ocelli are very indistinct. 



Omaliini. 

 Boreaphilus, Sahib. 



Body subelongate or oblong, scarcely convex, pubescent, alate or 

 apterus. 



Head large, prominent, suborbicular, larger than the thorax, bifo- 

 veolate in front, subemarginate and very strongly constricted at the 

 base with a short, rather narrow neck, one half the width of the 

 head at the vertex or scarcely narrower. Ocelli very distinct, distant, 

 more or less behind the posterior margin of the eyes. Tempora 

 mutic at the sides, genae rather strongly mammillate beneath, gula 

 strongly impressed. Epistoma convex, front broadly and feebly bi- 

 impressed between the eyes, truncate and obsoletely margined in 

 front. Labrum very short, broadly truncate at apex. Mandibles 

 elongate, slender, very acute, strongly falcate, unidentate internally. 

 Maxillary palpi strongly developed, first joint small, second elongate, 

 subarcuate, subclavate, third large strongly incrassate, pyriform, 

 truncate at apex, the last minute, subulate. Labial palpi small, three- 

 jointed, the last slender, the first stouter, subequal in length, slightly 

 larger at apex. Mentum large, transverse, truncate or scarcely sin- 

 uate at apex, anterior angles visibly projecting. Eyes moderate or 

 rather small, semiglobular, projecting, more or less distant from the
