1887. J JAPANESE ENDOMYCHID^. 647 



as long, the disk convex, finely and sparsely punctured, rather 

 piihesceut, the lateral margin raised and flattened, sides rounded into 

 the front angles. In the sulcate part of the disk, before the raiseil 

 margin, are many large punctures, and the margin itself is somewhat 

 sulcate and punctured. The elytra are thickly and finely punctured, 

 without any trace of striae, and are densely pubescent, with rather 

 long ragged grey hairs ; they are blackish, with an ill-defined basal 

 red spot, which covers the humeral angles, but does not quite reach 

 the suture. The legs are pitchy-black, v\ith pitchy-red tibise and 

 tarsi. The underside is wholly black. The prosternum is coarsely 

 punctured, including the posterior process, the breast smooth, the 

 abdomen slightly pubescent, with its basal segment obsoletely punc- 

 tured. 



Mr. Lewis informs me that this species was not rare in the 

 localities where he met with it. In its general appearance it reminds 

 one of Dacne, but it is pubescent and more parallel. 



BoLBOMORPHus, n. gen. 



Corpus oblongo-ovatum. Elytra convexa, valde gibbosa, apicibus 

 acuminatis. Antenna: modice elongata, clava parum dilatata. 

 Oculi fortiter granulati. Pnlpi maxillares articulo ultimo trun- 

 cato, sitbsubulato. Prothorax subquadratus, nitidus, angulis 

 anticis acutis, sulcis basalibus btevibus distinctis ; prosternum 

 latum, fortiter punctatum, processu lata quadrato, apice leviter 

 rotundato. Mesosternum transversum, utrinque antice sulcatum. 

 Scvtellum transverso-ovatum. Abdomen segmentis quinque tantum 

 distinctis, segmento basali tribus sequentibus longiore, inter coxas 

 valde latum, punctatum. Pedes vatidi, sat longi, femoribus hand 

 clavatis, tarsis breviusculis. 

 Sexus differentia latet. 



This new genus, the most interesting of Mr. Lewis's fresh discoveries 

 in this family, has very much the general appearance of Eumorphus, 

 but is in fact allied to Eucteanus, Gerst., by the wide prosternum, 

 and, apparently, by the absence of secondary sexual characters, 

 which are not usual in Gerstaecker's third division of the family, tlie 

 Endomychini. 



It differs from it in the structure of the club of the antennae, 

 which is largely developed in both E. hardwicki and E. marseuli, 

 while in the Japan insect it is very little evident at all. Even more 

 does it diverge in the coarsely granulated eyes and the wider pro- 

 thorax, which is shining, though punctured, instead of being opaque 

 as in both species of Eucteanus.
