the Cistelidae &c, of Japan. 271 



Bonzicus hypocrita, sp. n. (PI. VIII. fig. 4.) 



Elongatus, niger, subnitidus, parum pubescens ; elytris puuctatis, 

 hand striatis, azureo-micans ; antennis nigris, femoribus apice 

 rufo-flavis. 



L. 12-13 mill. 



Elongate, black, with short greyish pubescence, some- 

 what shining, with an azure tint above in some lights, espe- 

 cially on the elytra ; the head densely punctate; the thorax 

 Avidest posteriorly, less thickly punctured than the head, 

 bisinuate at base, cniarginate before the scutellum, basal 

 fove^e wide and somewhat deep ; the scutellum somewhat 

 rounded oiT behind, rather closely punctured ; the elytra 

 punctured like the thorax, without striee ; the antennte 

 densely black, with apical joint reddish or testaceous at the 

 tip ; the legs black, with the apices of the femora broadly, and 

 the bases of the tibia3 narrowly, reddish yellow or clear 

 yellow. In some examples there is a red patch, more or less 

 diffused, on the elytra around the scutellum, and in such 

 specimens the abdominal segments are margined with red. 



During life this insect, running on timber, looks like a 

 spotted Buprestis, the yellow colouring of the femora appearing 

 to be lateral spots on the elytra. 



Hah. Oyayama, Nikko, Chiuzenji, and Nishimura in June, 

 and Junsai and Sapporo in August. Not rare where there 

 are large decaying beeches. 



IvANiA, gen. nov. 



This genus is also proposed for a species which corresponds 

 generally with those of Melandrya. Maxillary palpi short, 

 and formed like certain species of Melandrya, e. g. rujipes, 

 Gebl. ; antenna3, two basal joints as in Melandrya, third 

 flattened and triangular, fourth similar but rather larger, fifth 

 again larger and similar to 6, 7, 8, and 9 ; tenth less trian- 

 gular and scarcely as wide, terminal smaller and conical ; 

 liead rather small, eyes a little prominent, thorax narrowest 

 anteriorly, widest before the base, canaliculate in the middle ; 

 scutellum nearly quadrate ; elytra 4-striate, strias with wide 

 interstices. 



Ivania coccinea, sp. n. (PI. VIII. fig. 5.) 



Elongata, nigra ; thorace infuscato, parte obscure cocciueo ; elytris 

 4-striatis, intcrstitiis dense rugoso-puuctatis, iu totum coccineis ; 

 antennis pedibusque nigris. 



L. 8-11 mill. 



Elongate, black, with short scarlet pubescence j the head
