300 ME. G. LEWIS ON JAPAN 



4. HiGONius ciLO, n. sp. (Plate XII. figs. 9, 10. 

 Eufo-testaceus, tliorace peropaco, in medio canaliculate ; elytris 



profunde sulcatis, prime fere obsolete, ceteris fortiter elevatis, 

 secundo ad apicem ducto, dorse nigro-maculato ; corpore subtus 

 rufo nigroque variegate. 



Testaceous, very opaque ; thorax divided in tbe middle by a deep 

 furrow, the disk on either side being dark or discoloured; the 

 elytra are broadly and convexly striate, with interstices punctate. 

 In the dorsal region there is a dusky or black spot on each 

 elytron near the suture. Legs robust, each thigh with a large 

 tooth. Length 2-2| lines. 



This species is the largest of the genus at present known. 

 It occurs not uncommonly under bark in the forests of Higo ; 

 and I have used the name of the province in forming the generic 

 name.

This species is allied, though not very closely, to B. Miles, 

 Boheni., from the Himalaya mountains. Mons. Hiller first dis- 

 covered it at Hagi, and I subsequently found it not uncommonly 

 under bark in May in the forests of Tuyama in Higo. In 

 June 1881 I chanced to beat a single male at Nara off a young 

 tree. 



thoracic grooves are peculiar, and occur in no other genus in the family. 

 Mr. A. S. Oliff has described a species from the Andamans, also with the 

 five grooves, viz. Higonius crux. 



Description of a new species o/ Higonius. By A. Sidney Oliff. 



Higonius crux, n. sp. — Elougatus, rufo-castaneus, convexiuseulus. Antennte 

 picese. Prothorax antice valde attenuatus, margine antico nigro, fortiter 

 longitudinaliter quadricarinatus. Elytra prothorace plus quam duplo longiora, 

 postice parum angustata; ad basin, sutura maculaque transversa communi 

 pone medium nigris ; quadricarinata interstitiis sat latis Itevibus. Corpus 

 subtus nitidum, Ijeve; abdominis segmentis nigris. Pedes rufo-brunnei. 

 Long. 3J millim. 



Hab. South Andaman Islands. 



Allied to Higonius Poweri, Lewis, but certainly distinct. It is larger, pro- 

 portionately broader, more brightly coloured, and has the ridges on the elytra 

 more clearly defined.
