the ElatoridfP nf Japan. 27 



that '' Japan " for a locality of a s|jocio.>--, in the present state 

 of our knowledge of the fauna of the islands, is not sufficient, 

 and, when possible, more precise information is needed. 

 Ja])an is a country which is subtropical in tlie south, and on 

 a large part of tlic northern area and on the mountains of 

 Central Jajian snow lies to a great depth five months in the 

 year ; and whether a species comes from one or the other it is 

 important to know. 



There are five species, viz. Elater azurescensj Cand., Mela- 

 )w(us niger and laficollis, Motsch., Cardiopliorus vulgaris^ 

 Motsch., and Agn'otes fei-niguu'penni's, Motsch., wliicli are 

 not recognizable by the published descriptions ; and there are 

 nine species which have been introduced to the Japanese 

 (Catalogue in error, viz. Lacon trifasciatus, Cand., Elater 

 Itgei, Lew., Melanoxanthns zebra, Wiedm., Limonius cylin- 

 dricus, Payk., Cardwphorus sohrinns, Lap., Corymhites 

 tessellafus, L., Corymhites fristis, Cand., Corymhites lateralis, 

 Lee, and Corymhites sericeus, Gebl. Some of these are noted 

 in the body of this paper, but their names are not admitted 

 to the list at the end of it. The list contains 181 species, of 

 which 104 are considered novelties.

This species and some others are inserted in tliis paper 

 to give, when it seems desirable, additional localities to show 

 their distribution. 



Adelocera antennata, sp. n. 



Eufo-brunnea, parum nitido, pilosula ; fronte triangulariter im- 

 prcssa ; thorace canaliculate ; elytris striis obsoletis, punctatis, 

 interstitiis externis convexis ; antennis articulis brevibus et 

 compressis. 



L. U mill. 



Rather parallel, reddish brown, little shining, clothed with 

 golden-grey hair ; the head triangularly impressed between 

 the antenna?, rather closely punctured ; the thorax channelled 

 in the middle, narrowest in front, and gradually and slightly 

 widening to the hind angles, hind angles slightly turned out- 

 wards and rather more acute than those of ^. Maklinii, 

 Cand., punctuation like that of the head ; the elytra, strise 

 obscurely impressed or obliterated by the punctuation, inter- 

 stices 3-6 more visibly convex than the others ; the antennae
